RESUMO

Squamous cell carcinoma is a common malignant condition affecting the oral cavity and may involve the surrounding maxillofacial regions. Treatment commonly involves resection of the tumor, followed by prosthetic rehabilitation of the resection defect. This clinical report presents a 62-year-old Asian male patient who had previously undergone surgical resection, resulting in a post-surgical Aramany Class II maxillary defect. The patient's medical history included severe trismus, characterized by restricted mouth opening, as well as a diagnosis of maxillary sinus verrucous squamous cell carcinoma. This report provides a comprehensive account of the rapid fabrication of an interim obturator using digitally assisted dentistry techniques.

RESUMO

This report describes the case of a 68-year-old man who visited our department complaining of poor denture retention and difficulty masticating due to damage to the retainer of a maxillary obturator. The patient had never been satisfied with the fit of this prosthesis, which had been placed two years earlier. The obturator and the mucosal surface of the denture base were incompatible, which had caused the retainer to detach. The maxillary defect was categorized as H3S0D0T0 according to the HS classification. The diagnosis was a masticatory disorder due to a damaged retainer and an incompatible denture base. Optical impressions and occlusal records were taken and a maxillary obturator fabricated using a CAD/CAM system. Dental CAD software was used to design and complete the tooth arrangement. The CAM system was used to mill a polyetherketoneketone disc based on the obtained data and composite resin used to face the teeth and gingiva. The maxillary obturator was placed after only three visits, spanning from impression taking to denture completion. The use of digital data allowed the time to denture completion to be shortened in addition to the number of hospital visits to be reduced. Compared to conventional impression taking, optical impressions also prevent discomfort, decreasing stress for the patient.

RESUMO

The dynamic of velopharyngeal sphincter mechanism is a complex motor skill involving coordination of soft palate and posterior and lateral pharyngeal walls. At rest, the soft palate drapes downward so that the oropharynx and the nasopharynx open allowing for normal breathing. However, during deglutition and certain speech, sounds such as plosives require complete or nearly complete velopharyngeal closure, whereas during utterance of vowels, the port needs to be open at varying degrees. Defects in velopharyngeal mechanism lead to hypernasality and decreased intelligibility of speech. The aim of this article is to understand the technique used to rehabilitate a patient with velopharyngeal insufficiency using a palatopharyngeal obturator prosthesis connected via a metal velar connector to a maxillary complete denture, with nasal endoscopic and lateral cephalometric examinations done to evaluate the outcome.

RESUMO

Purpose: To evaluate the nutritional status (NS) of patients planned for maxillectomy and prosthodontic rehabilitation using three nutritional assessment methods. Methods: This longitudinal study enrolled 18 planned maxillectomy patients following the inclusion and exclusion criteria. NS was evaluated at five stages: before surgery (S0), 2 weeks after surgery (S1), 3 months after insertion of intermediate obturator (S2), just before fabrication of definitive obturator (S3), and 3 months after insertion of definitive obturator (S4) using two nutritional assessment tools i.e. Patient Generated -Subjective Global Assessment (PG-SGA) &Nutritional risk index (NRI); and body composition indicators i.e. body mass index (BMI), fat free mass (FFM), total body water (TBW), skeletal muscle mass (SMM) and skeletal muscle mass index (SMMI).To determine the changes in patient's nutritional status among different time points Repeated Measure ANOVA with Bonferroni post hoc adjustments was used. Results: Out of 18 patients, 12 were completed the study. NS of maxillectomy patients deteriorates significantly (p < .05) till stage S2. At S3, significant improvement occurred as compared to stage S2, but it remained significantly less than pre-surgical level. However, at stage S4, all parameters were statistically comparable to S0 (p > .05) except for PG-SGA (p < .001) and SMM (p = .044). Conclusion: NS of maxillectomy patients worsen post surgically due to surgical morbidity and adverse effects of radiotherapy (RT) but improves with post-surgical healing, resolution of sequel of RT and improved oral function due to well-adapted obturator prosthesis.

RESUMO

Aim: The aim of this study was conducted to evaluate the effect of socioeconomic status (SES) on psychological distress and treatment satisfaction levels of patients who underwent maxillectomy and rehabilitation with obturator prosthesis. Settings and Design: Prospective, observational, analytic study. Materials and Methods: Forty-three patients undergoing maxillectomy were enrolled and divided into upper, middle, and lower SES groups, according to the updated Kuppuswamy SES scale. Psychological distress levels were assessed using Hospital Anxiety and Depression Scale (HADS) before maxillectomy (T0) and at 3 weeks after delivery of definitive obturator (T1). Treatment satisfaction levels with obturator prosthesis were assessed using Obturator Functioning Scale (OFS) at T1. HADS and OFS scores were then correlated with the SES of the participants. Results: Out of 43 participants, 7 were lost to follow up. The total number of participants in upper, middle, and lower SES groups was 14, 11, and 11, respectively. Before surgery, there was no significant difference in anxiety levels (P > 0.05) among different SES groups. However, the depression levels were the highest in the lower SES and decreased significantly with increasing SES. Prosthetic rehabilitation led to statistically significant (P < 0.05) fall in the levels of both anxiety and depression assessed at 3 weeks after delivery of prosthesis. The upper SES group was found to be less anxious and depressed compared to middle and lower SES groups after prosthodontic rehabilitation. Treatment satisfaction level was found to be significantly low (P = 0.005) in lower SES group as compared to upper SES group while no difference was found in between the middle SES when compared to higher or lower SES groups. Conclusions: SES has a profound impact on the patient's psychosocial well-being and treatment satisfaction. Patients of lower SES reported with higher psychological distress and lesser treatment satisfaction compared to those belonging to upper SES.

RESUMO

A sobrevivência de pacientes com câncer de cabeça e pescoço vêm melhorando, entretanto, algumas deformidades podem ocorrer devido dos tratamentos cirúrgicos que geram mutilações bucomaxilofaciais como perda de dentes, estruturas do palato, língua ou assoalho, resultando em alterações na fonética, mastigação e deglutição. Nesses casos há a necessidade que seja realizado uma reabilitação protética buscando torná-los indivíduos com menos problemas sociais, psicológicos e físicos, visto que mais procedimentos cirúrgicos estão contra indicados para solucionar os efeitos colaterais gerados pelo tratamento das neoplasias. Esse tipo de reabilitação protética com prótese ou placa obturadora possibilita benefícios na fonética, facilita a convivência social e atividades nutricionais como alimentação e deglutição, permitindo ao paciente uma vida com menos constrangimentos. Este trabalho tem como objetivo relatar dois casos clínicos onde os pacientes foram submetidos a reabilitação com placa obturadora palatina feitos após cirurgias oncológicas. Os pacientes de gêneros diferentes e com comunicações buco-nasal similares receberam o mesmo planejamento reabilitador que foram confeccionadas a partir de um molde que foi enviado ao laboratório. Após a instalação foi possível verificar que houve sucesso no tratamento, notando uma melhora imediata comprovando a eficácia do método reabilitador(AU)


This paper relates two clinical cases where patients were recovered with a palatal splint made after oncological surgeries. Survival of patients and necks can occur, however, some deformities can occur during oral and maxillofacial treatment, such as the appearance of teeth, palate structures, mutilations or posterior jaws, leading to changes in aesthetics, surgery and swallowing. If the need to perform a prosthetic rehabilitation is necessary so that the results are seen with less problems, psychological and physical, that more procedures are performed so that the effects of neoplasms are contraindicated by the treatment. This type of prosthetic rehabilitation with prosthesis or obturator plate provides benefits in phonetics, facilitates social coexistence and nutritional activities such as eating and swallowing, allowing the patient a life with less constraints. Patients of different genders and with similar oral and nasal communications received the same rehabilitation plan that were made from a mold that was sent to the laboratory. After installation, it was possible to verify that the treatment was successful, noting an immediate improvement, proving the effectiveness of the rehabilitation method(AU)

RESUMO

The number of patients undergoing a surgical resection of the maxilla for oncological reasons is constantly increasing, the most common complication of which remains the communication between oral and nasal cavities. On the basis of data arising from the literature regarding the treatment options of maxillary oncological post-surgical defects, obturator prosthesis remains the most used worldwide. We studied 25 patients (with at least 1-year follow up) rehabilitated by obturator prosthesis after maxillary resection leading to oro-nasal communication, providing data on the objective/subjective evaluation of such rehabilitation and mastication performance measured by a two-color chewing gum test. The type of defect was classified according to the classification system proposed by Aramany. Among the patients in our study, 72% rated a higher score for either stability and retention than for aesthetic appearance, as confirmed by the Kapur score rated by clinicians. The two-color chewing gum test shows similar results as only one patient had insufficient chewing function. Interestingly, we found no correlation between the masticatory function and residual denture, confirming that the maxillary obturator remains a predictable solution in such patients regardless of the anatomical alterations following surgery.

RESUMO

During the current pandemic scenario, maxillofacial rehabilitation specialists involved with supportive care in cancer must transform its practice to cope with COVID-19 and improve protocols that could quickly return the oral function of complex cancer patients who cannot wait for surgical complex rehabilitation. This includes the role of the maxillofacial prosthodontist for the rehabilitation of surgically treated patients with maxillary cancers by the means of filling obturator prostheses that are considered an optimal scientific-based strategy to reduce hospital stay with excellent pain control, oral function (speech, swallowing, mastication, and facial esthetics), psychologic and quality of life outcomes for the patients following intraoral cancer resection. Therefore, the aim of this commentary was to bring new lights to the strategic use of obturator prostheses for the rehabilitation of oral cancer patients during the COVID-19 pandemic as well as to present a protocol for managing such cases.

RESUMO

BACKGROUND: There is insufficient evidence for the efficacy of silicone soft reliner on the obturator prosthesis after maxillectomy for oral malignant tumors. OBJECTIVE: To verify the efficacy of silicone soft reliner on the obturator prosthesis after maxillectomy, by evaluating masticatory performance and quality of life (QoL). METHODS: This was a single-arm prospective interventional study, verifying the efficacy of silicone soft reliner (GC RELINE II®) on the maxillary obturator prosthesis. Data were obtained from a comparison of the endpoints after 14 days of continuous use of acrylic and silicone soft-lined prostheses. The primary endpoint was masticatory performance. The secondary endpoints were occlusal performance and oral health-related QoL (OHRQoL). The masticatory performance, occlusal performance, and OHRQoL were assessed by glucose concentration, maximum bite force, and the Japanese version of Oral Health Impact Profile (OHIP-J49), respectively. RESULTS: This study included five patients (two males, three females), aged between 71 and 88 years, with a median of 74 years. The median of glucose concentration indicated a statistically significant improvement between the acrylic resin (99.6 mg/dL) and silicone soft reliner (126.0 mg/dL) obturator prosthesis (p = .043). There was no significant difference in the median of maximum bite force between the acrylic resin (302.0 N) and silicone soft reliner (250.0 N) obturator prosthesis (p = .893). Functional limitations domain of the OHIP-J49 indicated a statistically significant improvement between the acrylic resin and silicone soft reliner obturator prosthesis (p = .043). CONCLUSIONS: This study indicated that an obturator relined with soft silicone improved masticatory performance and the OHRQoL post-maxillectomy.

RESUMO

INTRODUCTION: A definitive maxillary obturator prosthesis can be used to rehabilitate a maxillary defect with the aim of improving speech, deglutition, and elimination of oronasal regurgitation. The aims of this study were (1) to determine the time required to fabricate a definitive maxillary obturator prosthesis and (2) to compare the fabrication and follow-up times between a patient's first and second definitive maxillary obturator prosthesis. MATERIALS AND METHODS: A retrospective review was completed of patients that had maxillary definitive obturators fabricated following head and neck surgery from 2002 to 2018 (n = 173). Demographics, clinical data, date of surgery, start date of fabrication, follow-up dates, and prosthesis follow-up data were collected. RESULTS: The median time to delivery of the patient's first definitive maxillary obturator prosthesis from the date of surgery was 7.7 months for nonradiated patients and 9.6 months for radiated patients (P ≤ .05). Additionally, there was a significant difference in the median number of appointments to fabricate the 1st definitive maxillary obturator prosthesis as compared to the 2nd prosthesis (6 vs 5; P ≤ .05). CONCLUSION: Fabrication timelines differed based on history of radiotherapy and patient experience. This data is helpful to set expectations for patients and practitioners regarding the process for prosthesis fabrication and follow-up.

RESUMO

INTRODUCTION: Maxillectomy following tumors or, more rarely, traumatic injuries may result in maxillary defects that may determine physical dysfunctions and functional impairment of speech and swallowing. The aim of our study was to present our experience in the management of post-maxillectomy patients by the use of obturator prostheses that were obtained by 3D digital casts via an intraoral scanner. METHODS: Patients with maxillary defects following maxillary and/or palatal resection or maxillary traumatic avulsion were selected for this clinical study between 2015 and 2018. Five to 6 months after surgery, a definitive obturator prosthesis was fabricated thanks to an intraoral scanner. The following parameters of clinical outcome were considered: the absence of fluid leakage, the recovery of phonation, the recovery of swallowing, and personal satisfaction. RESULTS: Twenty-eight patients (20 males, 8 females) fulfilled the inclusion criteria and were included in the study. Most patients had a maxillary and/or palatal defect because of a malignant tumor. On the whole, 93% of patients reported a complete absence of fluid leakage between maxillary sinuses or nasal fossa and oral cavity; most patients reported a good or complete recovery of phonation and swallowing. CONCLUSIONS: Digital technology for the fabrication of maxillary obturator prosthesis may be effective and useful. The reduced laboratory working time, the avoidance of the risk of aspiration of impression materials, and the overcome of the difficulties associated with whole tissue undercut impression are just some of the most important advantages that have been encountered thanks to this promising technology.

RESUMO

Surgical reconstruction after a total maxillectomy remains challenging. The standard treatment is the microvascular free flap. In cases of surgical contraindication, oral rehabilitation is usually performed with a palatal obturator prosthesis (PAP). Acceptable anatomical and functional outcomes in terms of speech, mastication, aesthetic appearance, stability, and comfort are not often achieved with a PAP. This technical note describes a technique for reconstruction after total bilateral maxillectomy involving the implantation of a custom-made bone-anchored titanium prosthesis obtained by 3D printing. Good functional and anatomical outcomes were achieved with this technique. It combines the advantages of the obturator prosthesis (short duration of surgery and hospitalization, low morbidity) and free flap (aesthetic/anatomical reconstruction and irremovable comfortable functional rehabilitation). This technique constitutes a new therapeutic alternative for the restoration of large defects after total maxillectomy when free flaps are contraindicated.

RESUMO

Total maxillectomy for patients with malignant lesions will often incapacitate the patient both functionally and aesthetically. An immediate surgical obturator prosthesis would be of utmost importance for patients in these critical situations to aid in deglutition, phonetics, respiration and effectively avoiding various post-surgical complications. This article emphasizes on utilizing circum-zygomatic wiring for retention of the immediate surgical obturator in cases of total maxillectomy or edentulous patients.

RESUMO

Maxillary defects, whether congenital or acquired, make a patient encounter an array of physical and psychological difficulties, leading to an extremely poor quality of life. Rehabilitation of such a patient is often challenging due to the extent of the defect area coupled with the absence of adequate retention caused by the size and weight of the prosthesis. Further, providing a proper seal of the oronasal communication is of utmost importance to restore function. Taking the above factors into consideration, a combination of hollow-bulb obturator consisting of a titanium framework and a flexible, snap-on silicone cap is an effective prosthesis providing a long-term treatment, increased retention, and a happy patient. The fabrication protocol included the use of computer-aided design, titanium along with laser welding, and an intraoral trial before final fabrication, hence, reconfirming the success of the prosthetic design. The maxillary obturator presented in this article eliminates several disadvantages associated with a conventional hollow-bulb obturator, thereby providing a novel, viable option for a maxillofacial prosthodontist.

RESUMO

The treatment of head and neck cancers requires a team approach. Maxillofacial prosthetics and oncologic dentistry are involved in many phases of the treatment. After the cancer ablation surgery, if surgical reconstruction cannot not completely restore the surgical defect site, maxillofacial prostheses plays an important role to rehabilitate the patient's mastication, swallowing, and speech. For patients undergoing chemoradiation therapy, the outcome is enhanced by jaw positioning stent and fluoride carrier mouthpiece. This perioperative care by maxillofacial prosthetics improves the posttreatment outcomes and the patient's quality of life.

RESUMO

@#Unilateral maxillary defects are common clinical maxillofacial deformities. Because of their large area and the complexity of the maxillary structure, the distribution of pressure from dental prostheses and on the sustentacular tissue is usually uneven, which often results in pain or ulceration of the soft tissue and agomphiasis during the therapeutic process. Recently, the finite element method has been used to guide prosthesis design and implantation. This method is conducive to the restoration and stability of the dental prosthesis and the protection of the remaining tissue, which improves restoration quality and patient satisfaction. This paper summarizes the establishment of a three-dimensional finite element model of unilateral maxillary defects and its application in repairing unilateral maxillary defects with traditional prostheses, implant-supported prostheses and surgical flap transplantation combined with prostheses.

RESUMO

Obturator prosthesis is a common treatment method for maxillectomy patients for maintaining their oronasal separation and resuming their social lives. After tumor resection, the remaining anatomical structures have a significant effect on prosthesis retention. The present study describes the rehabilitation of two maxillectomy patients after cancer surgery using a prosthesis consisting of a denture and a special retentive obturator that is positioned in the anatomical undercuts of the nasal cavity. These patients have undergone total and subtotal maxillectomy surgery after the diagnosis of squamous cell carcinoma. The systemic and local health status of the total maxillectomy patient was not suitable for zygomatic implant surgery. Only one osseointegrated dental implant was placed into the left maxillary tuberosity area in the subtotal maxillectomy patient. In addition, the quality, vertical height, and horizontal width of the remaining bone structures in the maxilla limited the use of osseointegrated dental implants. Mechanical prosthesis retention was provided using a multiunit retentive mechanism composed of an orthodontic forsus fatigue resistant device (OFFRD), two Herbst appliances, and an acrylic piece associated with healthy keratinized mucosa. The OFFRD could easily apply a consistent force and push the acrylic pieces toward the retentive undercut under the control of the two Herbst appliances. Two OFFRD units in different directions were designed for the total maxillectomy patient, while only one OFFRD unit was placed on the opposite side of the osseointegrated implant in the subtotal maxillectomy patient. A sufficient retention was obtained for both patients. The patients were satisfied, and no major complications were observed in periodic controls.

RESUMO

O tratamento cirúrgico dos tumores da maxila e regiões adjacentes é realizado por meio de maxilectomia total ou parcial, porém, o defeito cirúrgico gerado por este tipo de tratamento leva a muitos comprometimentos clínicos e psicológicos para os pacientes. A reabilitação bucal imediata, por meio de uma prótese com obturador palatino pós-maxilectomia, leva à otimização do pós-operatório imediato, reabilitando suas funções estomatognáticas imediatamente após o tratamento cirúrgico e evitando maiores sequelas para os pacientes. O objetivo deste trabalho foi realizar uma revisão da literatura atualizada na base de dados PubMed, Scielo e Medline, sobre a qualidade de vida dos pacientes maxilectomizados e reabilitados com obturador protético, e relatar o caso de um paciente que realizou hemimaxilectomia e foi reabilitado na Policlínica Militar de Porto Alegre. Pôde-se concluir que os principais objetivos dos obturadores protéticos são restaurar as funções mastigatória e fonética, e diminuir o tempo cirúrgico e a reabilitação imediata do paciente, reinserindo-o no seu convívio social. Porém, quanto maior o defeito cirúrgico, maior a dificuldade para reabilitar, sendo a qualidade de vida do paciente extremamente dependente da função do obturador. Ainda não existe uma classificação adequada que descreva o defeito cirúrgico e indique o melhor tratamento, portanto, são importantes a interdisciplinaridade e a integração entre as diversas especialidades da saúde no tratamento e reabilitação destes pacientes.


The surgical treatment of maxillary and/or adjacent region tumors is performed by total or partial maxillectomy. However, the generated surgical defect leads to many clinical and psychological compromises. The immediate oral rehabilitation through the obturator prosthesis optimize the postoperative period retrieving the stomatognathic system immediately after treatment. The objective of this work was to carry out a literature review on PubMed, Scielo, and Medline databases regarding the quality of life of the maxillectomized patients receiving an obturator, and to report the case of a patient who underwent hemi-maxillectomy and was rehabilitated at the Military Polyclinic of Porto Alegre. It can be concluded that the main objectives of the prosthetic obturators are to restore the masticatory and phonetic functions, reducing the surgical time and reinserting the patient in the social meaning. However, the greater the surgical defect, the greater the difficulty to rehabilitate, where the patient´s quality of life greatly depends on the function of the obturator. There is still no adequate classification that describes the surgical defect and indicates the best treatment, Therefore, the interdisciplinary and integration among the different medical health specialties are mandatory in the treatment and rehabilitation of these patients.

RESUMO

PURPOSE: Several authors have described zygoma implants as a reliable surgical option to rehabilitate severe maxillary defects in case of extreme atrophy or oncological resections. The aim of this study is to report a new technical approach to the rehabilitation of a complex oronasal defect by means of a zygoma-implant-supported full-arch dental prosthesis combined with a nasal epithesis. PATIENTS AND METHODS: The patient presented with a subtotal bilateral maxillectomy and total rhinectomy defect because of a squamous cell carcinoma of the nose. No reconstructive surgery was performed because of the high risk of recurrence; moreover, the patient refused any secondary procedure. After surgery, the patient presented a wide palatal defect associated to the absence of the nasal pyramid. Zygoma-retained prostheses are well documented, and they offer good anchorage in rehabilitating wide defects after oncological surgery and a good chance for patients to improve their quality of life. We hereby describe two prosthetic devices rehabilitating two iatrogenic defects by means of a single intraoral implant-supported bar extending throughout the oronasal communication, thus offering nasal epithesis anchorage. RESULTS: At 1-year follow-up after functional prosthetic loading, no implant failure has been reported. Clinical and radiological follow-up showed no sign of nasal infection or peri-implantitis. The patient reported a sensitive improvement of his quality of life. CONCLUSIONS: Simultaneous oral and nasal rehabilitation of complex oronasal defects with zygoma-implant-supported dental prosthesis and nasal epithesis represents a reliable surgical technique. According to this clinical report, the above-mentioned technique seems to be a valuable treatment option as it is safe, reliable and easy to handle for both surgeon and patient.
