Resumo: As atrofias severas da mandíbula apresentam grande dificuldade de tratamento, seja através de próteses convencionais, seja por próteses implanto-suportadas. Várias técnicas são descritas para o aumento vertical do rebordo ósseo. Todas apresentam alta morbidade, dificuldade técnica e prognóstico duvidoso. Os implantes curtos apresentam uma solução mais simples, menos mórbida e atualmente apresentam prognóstico semelhante aos de tamanho convencional. O objetivo deste trabalho é apresentar 4 casos consecutivos de mandíbulas severamente reabsorvidas e tratadas com implantes de 7,5 a 10mm de comprimento e próteses tipo protocolo. Neste casos foram instalados 12 implantes sendo que apenas um não apresentou sucesso sendo substituído por outro implante instalado em carga imediata. Estes casos foram acompanhados por 30 a 36 meses não havendo nenhuma perda de implante após a instalação das próteses e havendo uma perda óssea perimplantar média de 0,71mm. Os casos apresentados mostram que o tratamento com 4 implantes de tamanho reduzido retendo prótese tipo protocolo são uma boa opção para o tratamento das mandíbuals atróficas.

Palavras-chave: mandíbula severamente reabsorvida, implantes dentários, implantes curtos.

 

Abstract: Severe atrophy of the jaw have great difficulty in treatment, either through conventional prostheses, either by implant-supported prostheses. Various techniques are described for increasing bone vertical edge. All have high morbidity, technical difficulty and doubtful prognosis. Short implants have a simpler, less morbid solution and currently have similar prognosis to conventional size. The objective of this paper is to present four consecutive cases of severely resorbed mandibles treated with implants and 7.5 to 10mm in length and protocol type prostheses. In 12 cases implants were installed and only one had not succeeded in being replaced by another implant installed in immediate loading. These cases were followed up for 30 to 36 months and there is no implant loss after prosthesis installation and having an average of 0.71 mm peri-implant bone loss. The cases presented show that treatment with 4 reduced size implant retaining type prosthesis protocol are a good choice for the treatment of atrophic mandíbuals.

Key words: severely resorbed jaw, dental implants, short implants.
