ABSTRACT
This article addresses diagnostic parameters that should be assessed in the treatment of extraction sockets with dental implant placement by presenting three case reports that emphasize the relevance of the amount of remaining bone walls. Diagnosis was based on the analysis of clinical and radiographic parameters (e.g. bone defect morphology, remaining bone volume, presence of infections on the receptor site). Case 1 presents a 5-wall defect in the maxillary right central incisor region with severe root resorption, which was treated with immediate implant placement. Cases 2 and 3 present, respectively, two- and three-wall bone defects that did not have indication for immediate implants. These cases were first submitted to a guided bone regeneration (GBR) procedure with bone graft biomaterial and membrane barriers, and the implants were installed in a second surgical procedure. The analysis of the preoperative periodontal condition of the adjacent teeth and bone defect morphology is extremely important because these factors determine the choice between immediate implant or GBR treatment followed by implant installation in a subsequent intervention.
RESUMO
Este artigo aborda os parâmetros clínicos que devem ser observados no diagnóstico e tratamento de alvéolos de extração por meio da instalação de implantes através da apresentação de casos clínicos, enfatizando a importância do número de paredes ósseas. O diagnóstico baseou-se na análise de parâmetros clínicos e radiográficos (p. ex morfologia do defeito ósseo, volume ósseo remanescente, presença de infecção na área receptora). O Caso 1 apresenta um defeito de 5 paredes relacionado a um incisivo central superior direito que apresentava extensa reabsorção radicular e foi tratado através da técnica de implante imediato. Os Casos 2 e 3 consistem em defeitos de 2 e 3 paredes ósseas presentes, respectivamente, que inicialmente não devem ser tratados com implantes imediatos, e, por isso, foram submetidos inicialmente ao procedimento de regeneração óssea guiada, com uso de biomateriais para enxertia e barreiras de membrana, para receberem implantes numa segunda etapa cirúrgica. A avaliação prévia das condições periodontais dos dentes adjacentes e da morfologia do defeito ósseo são extremamente importantes, uma vez que determinam se determinada área será tratada pela técnica de ROG ou pela técnica de implantes imediatos.
