A retrospective cohort study on dental implant survival in patients with grafted alveolar clefts.

OBJECTIVES

The aim of this study was to assess the survival rate of dental implants inserted in an alveolar cleft area where one or more bone graft procedures were performed and to identify possible factors that affect the survival rate.

MATERIALS AND

METHODS

The available data from 78 implants placed in 64 patients with grafted alveolar clefts were retrospectively analysed. Statistical analyses were performed using Kaplan-Meier survival analysis, log-rank tests and univariable Cox proportional hazard models.

RESULTS

The median follow-up period from insertion to the last follow-up appointment was 46 months (IQR: 29-79.3). In five patients, a single implant failed. This resulted in a cumulative survival rate of 95.0% at median follow-up. The factors investigated in this study did not have a significant effect on implant survival.

CONCLUSIONS

Dental implants placed in patients with alveolar clefts are a reliable treatment option for dental rehabilitation.
