ABSTRACT

Objective:

The aim of this study was to evaluate implant and prosthesis survival rates in full-arch rehabilitation supported by implants with platform-switched Morse taper connection submitted to immediate or delayed loading, after up to 5 years of follow-up. Material and

Methods:

Data was retrospectively collected from clinical records of patients who were treated by means of implant-supported full-arch rehabilitation. Survival rates of implants and prostheses were evaluated according to immediate or delayed loading.

Results:

The sample comprised 967 implants. Of those, 627 were submitted to immediate loading (IL) while 340 to delayed loading (DL). After a follow-up period of up to 5 years, the implant survival rate for IL was of 99.7% (622/627 implants) and 97.2% (333/340 implants) for DL. The overall implant survival rate was 98.8% (955/967 implants). Prosthesis survival rate was 100% (N = 178) for both groups. Significantly more implants in the DL group presented bone loss (p > 0.01), either greater or lower than 2 mm, during the follow-up period.

Conclusion:

Within their limits, the present results suggest that full-arch rehabilitation with platform-switched Morse taper connection implants can lead to surgical and prosthetic predictable outcomes. Moreover, immediate loading protocol seems to be a good option for the rehabilitation of fully edentulous patients, as it involves a shorter treatment time, which may lead to greater patient satisfaction.

RESUMO

Objetivo:

O objetivo deste estudo foi avaliar as taxas de sobrevivência de implantes e próteses em reabilitações de arco completo suportadas por implantes de conexão cone Morse e platform switching submetidos à carga imediata ou tardia, após até 5 anos de acompanhamento. Material e

Métodos:

Os dados foram coletados retrospectivamente em prontuários clínicos de pacientes que foram tratados por meio de reabilitação de arco completo suportada por implantes. As taxas de sobrevivência de implantes e próteses foram avaliadas de acordo com a carga imediata ou tardia.

Resultados:

A amostra foi composta por 967 implantes. Destes, 627 foram submetidos à carga imediata (IL) e 340 à carga tardia (DL). Após um período de acompanhamento de até 5 anos, a taxa de sobrevivência de implantes para IL foi de 99,7% (622/627 implantes) e de 97,2% (333/340 implantes) para DL. A taxa de sobrevivência geral dos implantes foi de 98,8% (955/967 implantes). Taxa de sobrevivência da prótese de 100% (N = 178) foi encontrada para ambos os grupos. Significantemente mais implantes no grupo DL apresentaram perda óssea (p > 0,01), seja maior ou menor que 2 mm, durante o período de acompanhamento.

Conclusão:

Os presentes resultados sugerem, dentro de seus limites, que a reabilitação de arco completo com implantes de conexão cone Morse e platform switching pode obter resultados cirúrgicos e protéticos previsíveis. Além disso, o protocolo de carga imediata parece ser uma boa opção para a reabilitação de pacientes totalmente edêntulos, pois envolve um menor tempo de tratamento, o que pode levar a uma maior satisfação do paciente (AU)
