Resumo(s)
As próteses sobre implantes são frequentemente utilizadas para reabilitar pacientes parcial ou totalmente edêntulos. Estudos publicados relatam taxas de sucesso elevadas e resultados a longo prazo satisfatórios para o paciente.
O planeamento da reabilitação é um passo essencial para o sucesso do tratamento. Uma das decisões importantes no planeamento passa pela escolha da conexão da reabilitação final ao implante.
Os diferentes tipos de mecanismos de retenção podem influenciar os resultados finais do tratamento, pois a estabilidade mecânica das coroas depende da engenharia do interface implante-pilar. Existem dois tipos principais de mecanismos de retenção utilizados: parafusos e cimento.
A escolha do modo de retenção, cimentada ou aparafusada, tem sido amplamente debatida nos últimos anos. Vários estudos tentaram responder à questão de saber se o uso de um modo específico de retenção resulta ou não em resultados mais favoráveis a longo prazo.
O sugerindo na literatura é a tendência para haver uma maior taxa de complicações biológicas nas coroas totalmente cimentadas e de complicações estéticas nas restaurações aparafusadas, no entanto, ainda não há um consenso na literatura sobre o sistema de retenção ideal: alguns autores defendem o uso de coroas aparafusadas e outros de cimentadas.
Prostheses on implants are frequently used to rehabilitate partially or totally edentulous patients. Published studies report high success rates and satisfactory long-term results for the patient. Rehabilitation planning is an essential step for successful treatment. One of the important planning decisions is the choice of the final rehabilitation connection to the implant. The different types of retention mechanisms can influence the final treatment results, as the mechanical stability of the crowns depends on the engineering of the implant-abutment interface. There are two main types of retention mechanisms used: screws and cement. The choice of retention mode, cemented or screwed, has been widely debated in recent years. Several studies have attempted to answer the question of whether or not the use of a specific mode of retention results in more favorable long-term outcomes. What is suggested in the literature is that there tends to be a higher rate of biological complications in fully cemented crowns and aesthetic complications in screwretained restorations. However, there is still no consensus in the literature on the ideal retention system: some authors advocate the use of screw-retained crowns and others cement-retained crowns.
