Abstract

Introduction: For a successful implant-supported rehabilitation and long-term maintenance in the anterior maxilla, it is imperative that the patient possesses adequate bone quality and quantity.

Objective: The aim of this study was to assess bone gain and stability following reconstruction with titanium mesh in the anterior region of the maxilla, irrespective of the biomaterial used for bone augmentation.

Material and method: Patient follow-up data were obtained from the Faculty's follow-up database. The focus was on individuals who had undergone rehabilitation in the anterior maxilla, previously augmented with bone grafts and growth factors in conjunction with titanium mesh. This retrospective cohort study involved at least 10 patients who met the inclusion criteria. Following an initial review of medical records, the eligible patients were invited for evaluation appointments.

Result: Out of 39 patients who had undergone guided bone regeneration surgery using titanium mesh, 12 met the inclusion criteria. As such, 17 sites suitable for the study were obtained, from which total of 276 tomographic measurements were then taken. There was a noticeable increase in thickness at all assessment levels relative to the bone crest apex, both immediately (T1) and six months post-surgery (T2), compared to baseline measurements (T0). Moreover, bone thickness tended to increase with the proximity to the apical level.

Conclusion: The use of titanium mesh combined with various biomaterials has yielded favorable outcomes in terms of augmenting bone volume.

Resumo

Introdução: Para o sucesso da reabilitação com implantes suportados e da manutenção dos resultados a longo prazo na região anterior da maxila, é imperativo que o paciente possua qualidade e quantidade óssea adequadas.

Objetivo: O objetivo deste estudo foi avaliar o ganho e a estabilidade óssea após a reconstrução com malha de titânio na região anterior da maxila, independentemente do biomaterial utilizado para o aumento ósseo.

Material e método: Utilizamos dados de pacientes oriundos do banco de dados da Faculdade, focando em indivíduos que haviam passado por reabilitação na maxila anterior previamente aumentada com enxertos ósseos e fatores de crescimento em conjunto com malha de titânio. Este estudo de coorte retrospectivo envolveu pelo menos 10 pacientes que atenderam aos critérios de inclusão.

Resultado: De um total de 39 registros no banco de dados de pacientes que passaram por cirurgia de regeneração óssea guiada utilizando malha de titânio, doze atenderam aos critérios de inclusão, enquanto os demais foram excluídos. Assim, foram obtidos 17 sítios adequados para o estudo, envolvendo 12 pacientes e um total de 276 medições tomográficas. Houve um aumento notável na espessura óssea em todos os níveis de avaliação em relação ao ápice da crista óssea, tanto imediatamente (T1) quanto seis meses após a cirurgia (T2), em comparação com as medições iniciais (T0). Além disso, a espessura óssea tende a aumentar com a proximidade do nível apical.

Conclusão: A utilização da malha de titânio combinada com vários biomateriais resultou em resultados favoráveis em termos de aumento do volume ósseo.
