ABSTRACT

Abstract Objective: To analyze and compare changes of quality of life parameter among dental patients rehabilitated by the implant-supported overdentures with different attachment systems. Material and Methods: Forty-eight patients were recruited as a study cohort. The implant placement procedure was based on the results obtained by CBCT scanning and individualized surgical templates manufactured for correct implant placement. Each individual received two k3Pro Implants (Sure Type with 4.0 or 4.5 mm in diameter) at the intraforaminal area due to standard protocol of implantation provided by the manufacturer under local anesthesia. All patients were distributed between two groups based on the fact of using either Locator- or ball-attachments. Rank correlation was measured using Spearman correlation coefficient, while linear correlation was evaluated by Pearson correlation coefficient. Results: No statistically meaningful differences were noted regarding patients' distribution among groups considering age (p>0.05) and gender (p>0.05). Provided patient-level analysis demonstrated that increase of conventional full denture service time was positively correlated with escalation of OHIP-EDENT scores. The most prominent inter-correspondences were noted specifically between longevity of denture service and elevation of scores within "Functional limitation" (r=0.61; p<0.05), "Physical pain" (r=0.51; p<0.05) and "Physical disability" (r=0.57; p<0.05) subdomains. No statistically argumented regressions were noted between increase tendency of OHIP-EDENT scores and gender (p>0.05) or age (p>0.05) parameters. Conclusion: Significant improvements of quality of life measured with OHIP-EDENT were noted for both types of attachments compared to the pre-treatment situation independently of additionally provided surface electromyography-based alignment.

ABSTRACT

Abstract The aim of this prospective, randomized, clinical study was to analyze the influence of occlusal adjustment on the prevalence of postoperative pain after endodontic treatment. Seventy-eight patients, diagnosed with symptomatic irreversible pulpitis with indication for endodontic treatment, were selected to participate in the study. The participants were randomized and divided into two groups: in the occlusal adjustment group (OAG), endodontic treatment was performed with subsequent occlusal adjustment. In the control group (CG), endodontic treatment was performed without occlusal adjustment. Treatments were performed by the same operator. Pain occurrence and intensity were recorded on two scales: the verbal rating scale (VRS) and numerical rating scale (NRS). Pain assessment was carried out by a second examiner, blinded to the experiment, 6, 24 and 72 h after endodontic treatment. Data were analyzed using Mann-Whitney, chi-squared, and Fisher's exact tests. In the occlusal adjustment group, 71.1% reported postoperative pain and 67.5% reported pain in the control group. At the 6-hour assessment, 21 individuals reported pain in the occlusal adjustment group and 24 in the control group (p=0.672). At the 24-hour assessment, 18 and 19 individuals reported pain (p=0.991) and at the 72-hour assessment, 8 and 4 reported pain (p=0.219), respectively. Occlusal adjustment did not influence the prevalence of postoperative pain of endodontically treated teeth with symptomatic irreversible pulpitis.


Resumo O objetivo deste estudo prospectivo, randomizado e clínico foi analisar a influência do ajuste oclusal na prevalência de dor pós-operatória após o tratamento endodôntico. Setenta e oito pacientes, diagnosticados com pulpite irreversível sintomática com indicação de tratamento endodôntico, foram selecionados para participar do estudo. Os participantes foram randomizados e divididos em dois grupos: no grupo de ajuste oclusal (GAO), foi realizado tratamento endodôntico com posterior ajuste oclusal. No grupo controle (GC), o tratamento endodôntico foi realizado sem ajuste oclusal. Os tratamentos foram realizados pelo mesmo operador. A ocorrência e a intensidade da dor foram registradas em duas escalas: a escala de classificação verbal (VRS) e a escala de classificação numérica (NRS). A avaliação da dor foi realizada por um segundo examinador, cego para o experimento, 6, 24 e 72 horas após o tratamento endodôntico. Os dados foram analisados utilizando testes de Mann-Whitney, qui-quadrado e exato de Fisher. No grupo de ajuste oclusal, 71,1% relataram dor pós-operatória e 67,5% relataram dor no grupo controle. Na avaliação de 6 horas, 21 indivíduos relataram dor no grupo de ajuste oclusal e 24 no grupo controle (p=0,672). Na avaliação de 24 horas, 18 e 19 indivíduos relataram dor (p=0,991) e, na avaliação de 72 horas, 8 e 4 relataram dor (p=0,219), respectivamente. O ajuste oclusal não influenciou a prevalência de dor pós-operatória após o tratamento endodôntico em dentes com pulpite irreversível sintomática.

ABSTRACT

Resumen Introducción: entre las maloclusiones, la mordida cruzada es la de mayor prevalencia entre los niños en edad preescolar y se considera la principal depreciadora del sistema estomatognático, con un alto riesgo de desarrollar secuelas musculoesqueléticas irreparables en la edad adulta. Por lo tanto, es fundamental elegir un tratamiento eficaz que no requiera la cooperación directa del paciente y que utilice técnicas simples de ortodoncia. El objetivo de este artículo es informar la eficacia del tratamiento de rehabilitación neuroclusal (RNO) con la técnica de las pistas directas de Planas en la corrección temprana de la mordida cruzada posterior y el seguimiento de su estabilidad oclusal durante siete años. Presentación del caso: niña de 4 años de edad, que usó biberón, diagnosticada con mordida cruzada posterior funcional unilateral izquierda y desviación de la línea media. Para el tratamiento de la RNO, se realizaron los ajustes oclusales en los dientes 63, 64 y 65, y después de la desprogramación neuromuscular, se confeccionaron las pistas directas de Planas en los dientes cruzados. Después de 29 días, se corrigió la mordida y se hicieron ajustes oclusales para proporcionar una mayor armonía oclusal. Hubo monitoreamiento cada seis meses durante siete años para verificar el equilibrio y la estabilidad del tratamiento. Conclusiones: la RNO con el uso de pista directa de Planas fue eficaz para corregir la mordida cruzada posterior con una técnica simple y de bajo costo que puede ejecutar el clínico general.


Abstract Introduction: Among malocclusions, that of cross-bite is the most prevalent among preschool children and is considered to be the main depreciator of the stomatognathic system and is further linked to a high risk of developing irreversible musculoskeletal sequelae in adulthood. Thus, it is important to choose an effective treatment early on that does not require the direct cooperation of the patient and that utilizes simple orthodontic techniques in its execution. The objective of this study was to report the efficacy of the Neuroclusal Rehabilitation (RNO) treatment, with the Planas Direct Tracks technique in a case of early treatment of posterior crossbite, and the follow up of its occlusal stability for seven years. Case presentation: a 4-year-old female patient, who was bottle-fed, was diagnosed with a left unilateral functional posterior crossbite and midline deviation. For treatment of RNO, occlusal adjustments were made on the teeth 63, 64 and 65 and after neuromuscular deprogramming, the Direct Planks were made in the crossed teeth. After 29 days, the bite was corrected, and occlusal adjustments were made in order to provide greater occlusal harmony. Monitoring and evaluation took place every six months for seven years in order to verify the balance and stability of the treatment. Conclusion: the RNO treatment with the use of Planas Direct Tracks is an effective solution for the correction of posterior crossbite using a simple, low-cost technique that can be performed by general practitioners.

ABSTRACT

Abstract Objective: To evaluate the accuracy of cone-beam computed tomography (CBCT) in the assessment of mandibular molar furcation defects. Material and Methods: Thirty patients with furcation defects were selected, oral hygiene instructions, scaling, and root planing with ultrasonic devices and hand instruments and occlusal adjustments were performed. Pre-surgical clinical measurements were carried out at the buccal aspect of the selected mandibular molars. The horizontal furcation measurements were measured with a Nabers Probe starting at the furcation entrance to the greatest horizontal depth. The degree of furcation involvement was graded from 0 to III. Bone loss in the horizontal and vertical direction and the width of the furcation entrance were measured on CBCT and after reflecting the full-thickness flap and debridement of the defects. The data were analyzed using t-test and Pearson's correlation coefficient. Results: The width of furcation entrance in clinical method was 3.27 ± 0.77, while in CBCT method was 3.35 ± 0.71, clinically the vertical bone loss was 3.61±1.09, while in CBCT was 3.57 ± 1.15, horizontal bone loss in clinical method was 5.08 ± 2.21, while in CBCT was 5.11 ± 2.23. No significant difference between the two methods was noted, and a high correlation between the two methods was observed. With regards to the agreement between the two methods of assessment, the width of furcation entrance revealed a difference between the two methods by 0.08 ± 0.21, while vertical bone loss showed difference between the two methods by -0.04 ± 0.19, the horizontal bone loss showed a mean difference between the two methods by 0.03 ± 0.21. Conclusion: CBCT provided high accuracy for the furcation involvement detection and anatomy of surrounding periodontal tissues.

ABSTRACT

This case report describes a technique in which endodontic treatment and permanent indirect restoration were completed in the same clinical appointment with the aid of a computer-aided design/computer-aided manufacturing (CAD/CAM) system. Two patients were diagnosed with irreversible pulpitis of the mandibular first molar. After access preparation, root canals were located, irrigation was performed until bleeding ceased, and the coronal tooth structure was prepared for indirect restoration. Then, utilizing an interim 3-mm build-up of the endodontic access cavity, a hemi-arch digital scan was performed with an intraoral scanner. Subsequent to digital scanning, restoration design was performed simultaneously with the endodontic procedure. The root canals were shaped using the Race system under irrigation with 2.5% sodium hypochlorite followed by root canal filling. The pulp chamber was subsequently filled with a 3-mm-thick composite resin restoration mimicking the interim build-up previously utilized to facilitate block milling in the CAD/CAM system. Clinical try-in of the permanent onlay restoration was followed by acid etching, application of a 5th generation adhesive, and cementation of the indirect restoration. Once the restoration was cemented, rubber dam isolation was removed, followed by occlusal adjustment and polishing. After 2 years of follow-up, the restorations were esthetically and functionally satisfactory, without complications.

ABSTRACT

Occlusion may change spontaneously but dental treatment or trauma in the patients with temporomandibular disorders (TMDs) may also alter occlusion. This report presents three cases displaying occlusal changes. Review of literature emphasizes the significance of TMD treatment. Conservative treatment modalities such as counseling, medication, physical therapy and splint therapy may be selected as initial treatment options. Irreversible or invasive treatment, such as orthodontic, prosthodontic, and occlusal adjustment should not be attempted early. In case there is no response to conservative treatment, joint injection, muscle injection, arthrocentesis or arthroscopic surgery might be performed.

ABSTRACT

PURPOSE: When performing an occlusal procedure, it is recommended that the patient should be sitting straight with the head in a natural position. An inappropriate mandibular position caused by an incorrect occlusal record registration or occlusal adjustment can result in damaged teeth and cause functional disorders in muscles and temporomandibular joints. The purpose of this study was to clarify the influence of horizontal cephalic rotation on mandibular position by investigating the three-dimensional positions of condylar and incisal points. MATERIALS AND METHODS: A three-dimensional jaw movement measurement device with six degrees of freedom (the WinJaw System) was used to measure condylar and incisal points. The subjects were asked to sit straight with the head in a natural position. The subjects were then instructed to rotate their head horizontally 0°, 10°, 20°, 30°, 40°, 50°and 60° in the right or left direction. RESULTS: The results indicated that horizontal cephalic rotation made the condyle on the rotating side shift forward, downward, and toward the inside, and the condyle on the counter rotating side shift backward, upward, and toward the outside. Significant differences in deviations were found for angles of rotation higher than 20°. The incisal point shifted in the forward and counterrotating directions, and significant differences were found for angles of rotation higher than 20°. CONCLUSION: The mandibular position was altered by horizontal cephalic rotations of more than 20°. It is essential to consider the possibility of deviation of the mandibular position during occlusal procedures.

ABSTRACT

PURPOSE: Fractures, occlusal adjustments, or marginal corrections after removing excess composite cements result in rough surfaces of all-ceramic FPDs. These have to be polished to prevent damage of the surrounding tissues. The aim of this study was to evaluate the roughness of zirconia, silicate-ceramic, and composite after polish with different systems for intraoral use. MATERIALS AND METHODS: Each set of 50 plates was made of zirconia, silicate-ceramic, and composite. All plates were ground automatically and were divided into 15 groups according to the treatment. Groups Zgrit, Sgrit, and Cgrit received no further treatment. Groups Zlab and Slab received glaze-baking, and group Clab was polished with a polishing device. In the experimental groups Zv, Sv, Cv, Zk, Sk, Ck, Zb, Sb, and Cb, the specimens were polished with ceramic-polishing systems “v”, “k”, and “b” for intraoral use. Roughness was measured using profilometry. Statistical analysis was performed with ANOVA and Scheffé-procedure with the level of significance set at P=.05. RESULTS: All systems reduced the roughness of zirconia, but the differences from the controls Zgrit and Zlab were not statistically significant (P>.907). Roughness of silicate ceramic was reduced only in group Sv, but it did not differ significantly from both controls (P>.580). Groups Cv, Ck, and Cb had a significantly rougher surface than that of group Clab (P < .003). CONCLUSION: Ceramic materials can be polished with the tested systems. Polishing of interface areas between ceramic and composite material should be performed with polishing systems for zirconia first, followed by systems for veneering materials and for composite materials.

ABSTRACT

PURPOSE: The purpose of this study was to evaluate and compare three polishing systems on the surface roughness and phase transformation of monolithic zirconia. MATERIALS AND METHODS: 100 disk shaped specimens (10 mm diameter, 3 mm thickness) were fabricated from monolithic zirconia blocks. 20 specimens were left as a control group and remaining specimens were grinded by diamond bur to simulate the occlusal adjustments. Grinded specimens were randomly divided into 4 groups: group G (no polishing), group M (Meisinger, zirconia polishing kit), group E (EVE Diacera, zirconia polishing kit), and group P (EVE Diapol, porcelain polishing kit). Surface roughness was measured with profilometer and surface topography was observed with SEM. XRD analysis was performed to investigate the phase transformation. Statistical analysis was performed with one-way ANOVA and Tukey's post hoc tests at a significance level of P=.05. RESULTS: All polishing groups showed a smoother surface than group G. Among 3 polishing systems, group M and group E exhibited a smoother surface than the group P. However, no significant differences were observed between group M and group E (P>.05). Grinding and polishing did not cause phase transformations in zirconia specimens. CONCLUSION: Zirconia polishing systems created a smoother surface on zirconia than the porcelain polishing system. Phase transformation did not occur during the polishing procedure.

ABSTRACT

PURPOSE: The purpose of this study was to evaluate the deformation of the complete denture artificial teeth arrangement after festooning over time. MATERIALS AND METHODS: 10 wax dentures of equal teeth arrangement and equal gingival contour were used in this study. Festooning of the wax dentures were conducted and 3D model scans were conducted every 10 minutes for 120 minutes. Interdental transverse distances were measured with the scanned images. Statistical analyses were performed with SPSS Ver. 22. 0. RESULTS: Interdental transverse distance between teeth varied from 0.0999 mm to 0.1787 mm. Mean rate of deformation showed statistically significant change between the 40 – 50 minute interval and 50 – 60 minute interval and between the 50 – 60 minute interval and 60 – 70 minute interval. No statistically significant change of the mean rate of deformation was observed later on. CONCLUSION: Monitoring of the interdental transverse distance for 120 minute after festooning have shown the deformation and displacment of the artificial teeth arrangement. From after the 60 – 70 minute interval after festooning, the mean deformation showed no statistically significant change of the mean rate of deformation was observed. Within the limitations of this in vitro study results suggest that the final occlusal adjustment in wax denture before complete denture curing should be proceeded at least 60 minutes later after festooning.

ABSTRACT

This article describes cases of applying non-surgical treatment including scaling and root planing, occlusal adjustment and tooth splinting of periodontally compromised lower anterior incisors Clinical and radiographic evaluations were performed over a 1–3-year period. All clinical parameters and radiographic bone levels improved in both cases. Dramatic regeneration of alveolar bone and lamina dura were observed on radiographic images, and no specific complications occurred during the follow-up period. Within the limitations of this study, these cases demonstrated the possibility of tooth rescue through non-surgical treatment and splinting of periodontally compromised teeth typically considered for extraction.

ABSTRACT

Introdução: a recessão gengival é caracterizada pelo desnudamento parcial da superfície radicular decorrente da migração apical da gengiva marginal e pela degradação do mecanismo de inserção gengival sobre o elemento dentário. Objetivo: descrever um caso clínico de retalho reposicionado coronalmente com a finalidade de recobrimento radicular em paciente que apresentava recessão gengival Classe I de Miller nos elementos dentários 23 e 24. Materiais e Métodos: O presente estudo contou com a participação de um paciente que queixava-se de hipersensibilidade dentinária, quando aplicado o estímulo térmico, e de insatisfação estética devido à exposição radicular visível ao sorrir e durante o ato de conversação. Foi traçado um plano de tratamento para o recobrimento radicular através de cirurgia de retalho reposicionado de forma coronal, seguido de encaminhamento para a realização de tratamento ortodôntico, já que o paciente possuía oclusão traumática na região acometida pela recessão gengival, decorrente da presença de contato prematuro. Resultados e Discussão: com a técnica empregada, foi possível restabelecer a normalidade estética, prevenir o acúmulo de biofilme dental, devido à maior facilidade de higienização da região cervical, permitindo também a redução da hipersensibilidade dentinária, anteriormente relatada pelo paciente. Conclusão: a técnica cirúrgica de retalho coronal, utilizada para a resolução deste caso, mostrou-se uma eficiente forma de tratamento, pois apresentou resultados satisfatórios levando-se em consideração a previsibilidade de recobrimento da superfície radicular para esta técnica, que é de 70 a 99% da área exposta, devolvendo assim, função ao elemento tratado.

Introduction: the gingival recession is characterized by the partial denudation of the root surface resulting from the apical migration of the marginal gingiva and by the degradation of the gingival insertion mechanism on the dental element. Objective: we present a clinical report of a coronally advanced flap with the purpose of root coverage in a patient who presented gingival recession Miller Class I in the elements 23 and 24. Material and Method: the patient complained of dental hipersensibility when a thermal stimulus was applied and also a aesthetics dissatisfaction due to a visible root exposure to smile and during the act of conservation. A treatment plan was traced for the root coverage by a coronally repositioned flat, followed by a orthodontic treatment due to premature contact. Results: with the technique employed, it was possible to restore aesthetic normality, to prevent the accumulation of dental biofilm due to an ease of cleaning the cervical region, also allowing the reduction of dental hipersensibility, previously reported by the patient. Conclusion: it's possible to claim that the surgical technique of coronal flap used to the resolution of this case is an efficient form of treatment taking into account the root surface coverage for this technique, which is of 70 to 99% of the exposure area, returning to the treated element its function.

ABSTRACT

El desgaste dental patológico, ocasionado por el bruxismo, es una alteración que se observa frecuentemente en la clínica odontológica. En este caso clínico fue realizado un procedimiento mínimamente invasivo, a fin de restablecer una guía anterior alterada por desgaste dental, asociado a otros tratamientos, tales como, el blanqueamiento dental y el ajuste oclusal. Este abordaje restaurador directo, asociado a las otras técnicas, posibilitó la máxima preservación de estructura dental remanente, alcanzando un excelente resultado estético y funcional, con una correcta adaptación del sistema estomatognático.

The dental tooth wear due to bruxism is an alteration that is seen frequently in the today ́s clinic. In this clinical case, a mini-mal invasive procedure was conducted aiming to restore the altered anterior guide by bruxism, associating other treatments, such as occlusal adjustment and bleaching. This direct restorative approach associated to the aforementioned treatments, made possible the maximum preservation of the tooth structure, reaching excellent functional and esthetic results, with a correct adaptation of the stomatognathic system.

ABSTRACT

The objective of this study was to compare the masticatory performance with bilateral balanced occlusion and lingualized occlusion in complete denture patients reporting to Armed Forces Institute of Dentistry Pakistan. A randomized control trial study was carried out on sixty edentulous patients. Subjects were divided into two equal groups, A and B by non-probability consecutive sampling method. Group A patients were provided complete dentures with bilaterally balanced occlusion and group B patients were provided complete dentures with lingualized occlusion. Masticatory performance was determined at the 01-month follow-up appointment using Sieving method. Data were analyzed using SPSS 19.0.Results of the study showed that patients with bilateral balance occlusion dentures had superior masticatory performance as compared to ones' with lingualized occlusion. Conclusion made was that bilateral balance occlusal scheme patients were able to masticate properly with ease and comfort and were more comfortable with their prostheses

ABSTRACT

The development of translucent zirconia enabled clinicians to choose a monolithic zirconia crown as one treatment modality in the posterior dentition. Careful occlusal adjustments are recommended for monolithic zirconia crowns because grinding zirconia inevitably causes phase transformation, which may deteriorate mechanical properties. intraoral scanners enable the clinician to scan and superimpose a complete tooth structure before preparation onto the prepared abutment. This technique helps to reproduce the original tooth form and occlusion of the patient. In this case report, prostheses were fabricated for patients with cracked or fractured tooth by applying intraoral scanner, Computer aided design-computer aided manufacturing (CAD-CAM) and monolithic zirconia crown to reproduce the occlusion of original tooth and to minimize occlusal adjustment. The clinical results were satisfactory in both esthetic and functional aspects.
