Survival Rates of Dental Implants in African Patients: A 5-Year Follow-Up Study

Abstract

The success of dental implant therapy has been extensively documented in Western populations, yet limited evidence exists regarding implant survival rates in African patients. This prospective cohort study examines the 5-year survival rates of dental implants placed in African patients across multiple clinical settings, with particular attention to factors influencing implant success. A total of 847 implants placed in 412 patients across five African countries were monitored from 2018 to 2023. The overall cumulative survival rate was 94.2% at 5 years, with variations observed based on geographic location, bone quality, implant site, and patient-specific factors. Maxillary implants demonstrated a survival rate of 92.8% compared to 95.1% in the mandible. Factors such as smoking status, diabetes control, and oral hygiene compliance significantly influenced outcomes. The findings suggest that dental implant therapy can achieve comparable success rates in African populations when proper protocols are followed, though specific considerations related to bone density patterns, dietary factors, and healthcare accessibility must be addressed. This study provides crucial baseline data for clinicians treating African patients and highlights the need for culturally adapted treatment protocols and patient education strategies.
