ABSTRACT
Introducción: Los implantes dentales de circona son una buena opción terapéutica que surge como alternativa a los implantes dentales convencionales de titanio, dadas sus excelentes propiedades de biocompatibilidad, baja acumulación de placa bacteriana y escaso infiltrado inflamatorio. El objetivo del presente caso clínico es describir la colocación de un implante monobloque de circona para reponer un incisivo lateral superior izquierdo en un paciente de 34 años de edad, para la posterior realización de una corona implantosoportada monolítica de circona. Descripción del caso: Se presenta un paciente varón de 34 años de edad, no fumador y sin antecedentes médico-quirúrgicos de interés (ASA I), que acudió a la consulta demandando una mejora en la estética de su sonrisa. El paciente presentaba una agenesia congénita en el incisivo lateral superior izquierdo que había sido tratada previamente con ortodoncia para cerrar dicho espacio. Tras el examen intraoral del paciente y el estudio radiográfico, se plantea la opción de tratamiento de abrir nuevamente el espacio mediante ortodoncia para rehabilitar la ausencia con un implante de circona, asegurando la estética que demandaba el paciente. Conclusiones: La rehabilitación mediante implantes de circona para el tratamiento de agenesias congénitas en incisivos laterales superiores, es una opción válida y efectiva, obteniendo resultados óptimos a nivel estético y funcional. Sin embargo, se necesitan más estudios clínicos con tamaños muestrales suficientes que comparen implantes de titanio y cerámicos con el fin de tener datos más concluyentes. (AU)
Introduction: Zirconia dental implants are a good therapeutic option emerging as an alternative to conventional titanium dental implants, given their excellent properties of biocompatibility, low bacterial plaque accumulation and low inflammatory infiltrate. The aim of the present clinical case is to describe the placement of a zirconia implant to replace an upper left lateral incisor in a 34-year-old patient, for the subsequent restoration of a monolithic implant-supported zirconia crown. Case description: A clinical case of a 34-year-old man is presented, nonsmoker and with no previous registered medical records (ASA I) who came to the dental clinic demanding an improvement in the aesthetics of his smile. The patient had a congenital agenesis of the left lateral incisor that had previously been treated with orthodontics to close the space. After the radiographic study and intraoral examination of the patient, the treatment option of reopening the space with a new phase of corrective orthodontics to rehabilitate the absence with a zirconia implant was proposed, ensuring the aesthetics demanded by the patient. Conclusions: Restoration using zirconia implants for the treatment of congenital agenesis in upper lateral incisors is a valid and effective option, obtaining optimal aesthetic and functional results. However, more clinical studies with sufficient sample sizes comparing titanium and ceramic implants are needed in order to have more conclusive data. (AU)

Objetivo: apresentar o relato de duas pacientes com agenesias dentárias em que cinco dentes autotransplantados foram utilizados como modalidade de tratamento. Além disso, objetiva-se mostrar questões sobre a técnica cirúrgica, suas indicações e previsibilidade. Relato de caso: Neste estudo, foram relatados 5 casos de autotransplante dentário em duas pacientes jovens, em que a equipe realizou os procedimentos e o acompanhamento clínico e radiográfico por 5 e 7 anos. Devido à alta sensibilidade da técnica, foram seguidos princípios previamente estabelecidos na literatura envolvendo o autotransplante dentário. Durante o período de acompanhamento, os dentes se mantiveram em posição e em função e as pacientes não apresentavam queixas associadas. Considerações finais: a técnica do autotransplante dentário, quando bem indicada e executada, é capaz de promover resultados bastante satisfatórios, sendo uma ótima alternativa reabilitadora, com taxas de sucesso elevadas e custos reduzidos. No entanto, critérios em relação aos sítios doadores e receptores e a habilidade do cirurgião devem ser levados em conta para o sucesso do técnica.
Objective: presenting the report of two patients with tooth agenesis in which five autotransplanted teeth were used as a treatment modality. Furthermore, the aim is to show questions about the surgical technique and its indications and predictability. Case report: In this study, 5 cases of dental autotransplantation were reported in two young patients, in which the team performed procedures and had clinical and radiographic follow-up for 5 and 7 years. Due to the high sensitivity of the technique, principles previously established in the literature involving dental autotransplantation were followed. During the follow-up period, the teeth remained in position and function and the patients had no associated complaints. Final considerations: the dental autotransplantation technique, when well indicated and executed, is capable of achieving very satisfactory results, being a great rehabilitative alternative, with high success rates and reduced costs. However, criteria regarding donor and receptor sites and the surgeon's skill must be taken into account for the success of the technique.

In the early 1900s, various authors worked on "artificial roots" to replace missing teeth. E. J. Greenfield's pioneering works (1910-1913) are among the best-known today and are often cited in publications reviewing the history of oral implantology. Shortly after Greenfield's first communications in the scientific literature, a French dental surgeon, Henri Léger-Dorez, designed the first expanding dental implant, which he indicated was used successfully in cases of single tooth edentulism. Its aim was to obtain the best primary stability and thus avoid the use of dental splint during osseous healing process. Léger-Dorez's works give us a new angle on the research in oral implantology by the pioneers of the early 20th century.

The absence of teeth in children due to congenital agenesis, syndromic or not, could lead to oral dysfunctions with general repercussions and sociopsychological problems. This case was a 17-year-old girl with severe nonsyndromic oligodontia who was missing 18 permanent teeth and had a class III skeletal pattern. It was challenging to provide functional and esthetically pleasing results in terms of temporary rehabilitation during growth and long-term rehabilitation in adulthood. This case report described the originality of the realization steps of oligodontia management, in 2 main parts. The osseous time by the LeFort 1 osteotomy advancement with simultaneous parietal and xenogenic bone grafting to improve a large bimaxillary bone volume, allowing future early implant placement by absence of growth of adjacent alveolar processes. The prosthetic rehabilitation with the conservation of natural teeth for proprioception and the use of a screw-retained polymethyl-methacrylate immediate prostheses to evaluate the needed vertical dimensional changes and make functional and esthetic results more predictable. This article could be retained as a technical note to manage this kind of case with the intellectual workflow and the difficulties encountered.

INTRODUCTION: the aim of this study was to report and assess the management and implant rehabilitation of oligodontia patients since its recognition in 2012 by french authorities in the nomenclature. MATERIAL AND METHODS: we conducted a retrospective study in the Maxillofacial Surgery and Stomatology Department of the Lille University Hospital between January 2012 and May 2022. Patients had to present an oligodontia recognized under the ALD31 in adulthood, and to have benefited from a pre-implant/implant surgical treatment in the unit. RESULTS: a total of 106 patients were included in the study. The mean number of agenesis was 12 per patient. The most missing teeth are the ones at the end of the series. After a pre-implant surgery phase including orthognathic surgery and/or bone grafting, 97 patients benefited from implant placements. The mean age for this phase was 19.38. A total of 688 implants were placed. The median number of implants placed was 6 per patient and 5 patients presented implant failures after or during the osseointegration phase (16 implants lost). The implant success rate was 97.6%. 78 patients benefited from rehabilitations by fixed implant-supported prostheses and 3 by implant-supported mandibular removable prostheses. DISCUSSION: The described care pathway seems to us adapted to the patients followed in our department, with good functional and esthetic results. It would be necessary to evaluate on a national scale to adapt the management process.

Treatment of pediatric patients with partial anodontia is a challenge requiring interdisciplinary approach. Growth period, reduced vertical dimension, microdontia, and unacceptable esthetics present difficulties at various stages of prosthetic rehabilitation. Congenital absence of teeth impairs the nutritional status of the growing child and causes a psychological setback. This article describes the prosthetic management of a patient suffering from partial anodontia done over a period of 10 years. Considering the age and psychological and financial requirements of the patient, removable and fixed prostheses were fabricated at different phases of the treatment. The ultimate aim was restoration of function, improvement of esthetics, and overall psychological upliftment of the patient which was achieved by maxillary metal ceramic bridge and mandibular implant retained hybrid prosthesis.

Maxillary lateral incisor agenesis (MLIA) is a condition that significantly compromises smile esthetics and is a particular concern in younger patients. The treatment options include orthodontics for space opening with rehabilitation or space closure with canine camouflage. Currently, there is some controversy regarding the most appropriate treatment. In this case report, we propose a multidisciplinary approach through the combination of orthodontic treatment, frenectomy, and a restorative finishing stage with composite resin and dental implants. More specifically, this treatment was planned to orthodontically close the anterior space by opening the premolar area for subsequent placement of implants and enameloplasty with a composite resin. The replacement of a missing lateral incisor by an implant is a predictable treatment approach, but it might best be deferred until dental maturity and then accurately placed in a well-developed site through a multidisciplinary approach. Precluding the closure of the anterior spaces and the opening of the posterior zone for implant placement, allows for a more stable and appealing esthetic and functional rehabilitation for young patients, in whom esthetic appearance and self-esteem play a primary role.

Hypodontia is commonly associated with cleft lip and/or palate and can be managed by autotransplantation of teeth. In this case report, autotransplantation of the immature mandibular right second premolar to replace the congenitally missing maxillary right second premolar was performed successfully in an 11-year-old Chinese male. An ectopic tooth resembling a premolar tooth was subsequently noted to be developing palatal to the root apex of the transplanted tooth one month after surgery. The development of a dental tooth germ at the site of the autotransplantation post-surgery is a possibility and clinicians should be aware and monitor for such development. The development of a tooth germ post-autotransplantation of an immature tooth could provide a new perspective into tooth organogenesis in patients with agenesis of permanent teeth.

BACKGROUND: Ectodermal dysplasia is a congenital genetic disorder with a prevalence of 1:10,000 to 1:100,000. The clinical features of ectodermal dysplasia include sparse hair, missing teeth, and abnormal development of the skin, sweat glands, and other tissues and organs. Since 1985, dentists have used implants to correct tooth defects in patients with ectodermal dysplasia with reasonable success rates. However, there is still no widely accepted treatment for the oral defects caused by this disease.Case summary: This report describes a 19-year-old female patient with congenital ectodermal dysplasia, congenital absence of most of her teeth, and mandibular and maxillary dysplasia. The patient and her family were concerned about the patient's growth and development, so she came to our hospital to restore her missing teeth. During several months of treatment, the patient underwent bone augmentation surgery for the maxilla and mandible, implant placement, a root repositioning flap, and free gingival grafting, which was completed in five stages. The patient completed the permanent implant restoration, and the desired results were achieved. CONCLUSION: The patient's mouth was restored through the use of bone augmentation and soft tissue grafting techniques, enabling appropriate function and appearance.

The replacement of the missing maxillary lateral incisor continues to be a challenge for the interdisciplinary dental treatment team. Over the past two decades the dental implant has become a primary method of replacement for this tooth. However, while implants offer numerous benefits, some significant potential problems are associated with implant treatment, including the possible need for tissue grafting, the long-term stability of bone and soft tissue overlying the facial surface of the implant, as well as the continued growth of alveolar bone and eruption of teeth adjacent to the implant. This article discusses various treatment options for the replacement of the missing maxillary lateral incisor with an emphasis on the bonded zirconia bridge.

Tooth autotransplantation is performed in patients with congenitally missing teeth and those with traumatic tooth loss. We report a course of edgewise treatment of a girl with multiple congenitally missing teeth and residual features of ectodermal dysplasia, who was treated with autotransplantation of 2 premolars with developing roots. She was 8 years old at the beginning of the treatment. No signs of inflammation, root resorption, or pulp symptoms were observed during the 2.5 years of edgewise treatment after autotransplantation. Cervical external root resorption was detected 31 months postoperatively in 1 transplanted tooth (maxillary first premolar), and the same problem occurred in the other transplanted tooth (mandibular second premolar) 2 years later. Root canal treatment was immediately undertaken and resulted in inhibition of further pathology. Consequently, the survival of both transplanted teeth was achieved. The orthodontic treatment that included intervals related to diagnosis and treatment of root resorption of the transplanted premolars is described in detail.

Resumo A agenesia dentária é a malformação craniofacial mais prevalente em humanos. Pode apresentar uma grande variedade de manifestações e, dependendo do número e localização dos dentes ausentes, pode afetar a estética, a mastigação, a fala e o equilíbrio da oclusão. Neste artigo, serão discutidas as propostas terapêuticas para resolução dessa condição e será descrito um caso clínico com agenesia de um incisivo lateral inferior, cuja opção de tratamento foi o fechamento do espaço remanescente da agenesia, associado ao incremento de resina composta nos incisivos centrais inferiores. No acompanhamento por três anos após o tratamento, verificou-se estabilidade oclusal, adequada intercuspidação em Classe I e excelente micro e macroestética.

Dental autotransplantation is the surgical transposition of a tooth from its original site to another site to replace a lost or compromised tooth in the same individual.1 It offers a method for replacing missing teeth or avulsed and traumatized teeth, particularly in children and adolescents. This surgical therapy is often overlooked as a treatment option by dentists and oral surgeons, who typically treat space closure by placing dental implants or bridges despite the fact that recent autotransplantation studies show high survival rates and success rates of 91.3%.2 Most tooth losses due to traumatic incidents occur in young patients, and implant placement is contraindicated until the completion of growth. In cases where there is no donor dilemma, and if a suitable graft is available, autotransplantation may be the therapy of choice.

STATEMENT OF PROBLEM: Long-term assessments of implant survival and treatment outcome in patients with oligodontia are lacking. PURPOSE: The purpose of this retrospective clinical study was to assess which factors determine a long-term implant survival and treatment outcome of up to 25 years in a cohort of patients with oligodontia. MATERIAL AND METHODS: The medical records of all patients with oligodontia treated with fixed implant prosthodontics between January 1991 and December 2015 in the Department of Oral and Maxillofacial Surgery at the University Medical Center Groningen, the Netherlands, were assessed. Specifically, this involved the retrieval of records on the need for and mode of bone augmentation, implant survival, and survival of and adverse events associated with the prosthodontics. The Kaplan-Meier estimator was used to analyze implant and superstructure survival. Log-rank tests were used to compare the survival of subgroups. RESULTS: A total of 126 patients with oligodontia were treated with dental implants. Of the 777 implants in total, 56 were lost, resulting in a 5-year cumulative survival of 95.7% (95% confidence interval [CI], 94.2% to 97.2%) and a 10-year cumulative survival of 89.2% (95% CI, 86.2% to 92.2%). The survival of implants placed in regions where bone augmentation surgery had been performed was significantly lower. The 5-year cumulative superstructure survival was 90.5% (95% CI, 87.6% to 93.5%), and the 10-year cumulative superstructure survival was 80.3% (95% CI, 75.3% to 85.3%). The performance of the screw-retained and cemented superstructures was comparable, but the survival of single crowns was significantly higher than the survival of fixed partial dentures (P<.001). CONCLUSIONS: Implant treatment is a predictable treatment option for patients with oligodontia with a favorable long-term outcome. Survival of implants in augmented areas is lower.

Here, we report a case of dental implant treatment involving computer-assisted surgery for bilateral agenesis of the maxillary lateral incisors. The patient was a 39-year-old woman with the chief complaint of functional and esthetic disturbance due to maxillary and mandibular malocclusion. The treatment plan comprised non-extraction comprehensive orthodontic treatment and prosthodontic treatment for space due to the absence of bilateral maxillary lateral incisors. A preliminary examination revealed that the mesiodistal spaces left by the absent bilateral maxillary lateral incisors were too narrow for implant placement (right, 5.49 mm; left, 5.51 mm). Additional orthodontic treatment increased these spaces to approximately 6 mm, the minimum required for implant placement if risk of damage to the adjacent teeth due to inaccuracies in directionality of drilling is to be avoided. For dental implant treatment with computer-assisted surgery, preoperative planning/simulation was performed using Simplant® ver.12 software and a toothsupported surgical template fabricated using stereolithography. Two narrow-diameter implants were placed in a two-stage procedure. It was confirmed that there was sufficient distance between the implant fixtures and the roots of the adjacent teeth, together with no exposure of alveolar bone. Following a 4-month non-loading period, second-stage surgery and provisional restoration with a temporary screw-retained implant crown were performed. Cement-retained superstructures made of customized zirconia abutment and a zirconia-bonded ceramic crown were fitted as the final restoration. At 5 years after implant surgery, there were no complications, including inflammation of the peri-implant soft tissue and resorption of peri-implant bone. Computer-assisted implant surgery is useful in avoiding complications in bilateral agenesis of the maxillary lateral incisors when only a narrow mesiodistal space is available for implant placement.

It is known that congenitally missing teeth can often cause differences in craniofacial morphology; however, there are few reported cases of orthognathic surgical treatment for these patients. Herein, the authors report a rare case of maxillary hypoplasia with congenital oligodontia treated by maxillary distraction osteogenesis with internal device. A 17-year-old male presenting with multiple tooth agenesis and maxillary recession was referred to our hospital for orthognathic surgical treatment. Preoperative simulation surgery was performed using Full-Color 3-dimensional salt model. After surgery, improvement in maxillary recession and occlusal stability was observed. This report demonstrates the advantages of the method used herein, which includes reduction in operating time with increase in the safety of the procedure.
