Resumo

OBJECTIVE: Survival rates of mandibular overdentures on two implants retained by bar-clip system with immediate loading and the factors related to fractures was analyzed.
METHODS: Twenty-three subjects were followed for 32 months. Fracture occurrence was the outcome variable, while the thickness of denture base, maxillomandibular space and masticatory efficiency comprised the independent variables.
RESULTS: The survival rate was 49.5%, with 34.7% of fractures. There was no association between the independent variables and fractures.
CONCLUSION: So, the risk of mandibular overdenture fractures with immediate loading is high. Furthermore, masticatory efficiency, thickness of the denture base and maxillomandibular space did not influence the incidence of fractures.

 

*** Sobrevida e fatores associados a fraturas de sobredentaduras inferiores com carga imediata *** 

OBJETIVO: A taxa de sobrevida de sobredentaduras mandibulares com dois implantes retidas por sistema barra-clipe com carga imediada e os fatores associados a fraturas foram analisados.
METODOLOGIA: Vinte e três indivíduos foram acompanhados por 32 meses. A ocorrência de fratura foi a variável dependente, enquanto a espessura da base da prótese, o espaço maxilomandibular e a eficiência mastigatória compreendeu as variáveis independentes.
RESULTADOS: A taxa de sobrevida foi de 49,5%, com 34,7% de fraturas. Não houve associação entre as variáveis independentes e as fraturas.
CONCLUSÃO: Assim, o risco de fraturas de sobredentadura mandibular com carga imediata é alto. Além disso, a eficiência mastigatória, a espessura da base dentária e o espaço maxilomandibular não influenciaram na incidência de fraturas.

Palavras-chave: dentadura; prótese dentária; implantes dentários; carga imediata.
