Implante de zircônia e regeneração óssea guiada em área estética: relato de caso com acompanhamento de cinco anos e nove meses

RESUMO

O objetivo desse relato de caso foi apresentar uma regeneração óssea guiada associada a implante de zircônia em área estética. Foi instalado um implante de zircônia em região de dente 21, onde havia ausência de tábua óssea vestibular. Associou-se regeneração óssea guiada usando enxertos autógeno e xenógeno com barreira biológica. O contorno gengival foi obtido a partir de prótese provisória. A paciente foi acompanhada através de tomografias no período de um ano pós-operatório e clinicamente durante cinco anos e nove meses, não sendo observados sangramento gengival, perda óssea ou afecções locais. Observou-se que é possível obter um resultado estável a longo prazo com regeneração óssea guiada e implante de zircônia em área estética, entretanto mais estudos clínicos randomizados a longo prazo são necessários.

Palavras-chave – Implantes dentários; Regeneração óssea; Materiais biocompatíveis; Óxido de zircônio.


ABSTRACT

The purpose of this case report is to present a guided bone regeneration therapy associated with a zirconia dental implant in an aesthetic area. A zirconia implant was installed in the region of tooth 21, where there was no vestibular bone plate, and guided bone regeneration using autogenous and xenogeneic grafts with a biological barrier was associated. The gingival contour was obtained from a temporary prosthesis. The patient was followed up by CT scans in the period of 1 year post-operatively and clinically for five years and nine months, in which there wasn’t any gingival bleeding, bone loss or local conditions observed. It was noticed that it is possible to obtain a stable long-term result with guided bone regeneration and zirconia implantation in an aesthetic area; however, more long-term randomized clinical studies are needed.

Key words – Dental implants; Bone regeneration; Biocompatible materials; Zirconium oxide.
