Abstract

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.
