It is concluded that recommendations for treatment of apical peri-implantitis are still minimal. In the present study, a surgical approach with resection of the apical portion of the affected implants in combination with debridement is suggested. Our experience was that partially resected oral implants remain osseointegrated and also function well clinically with a follow-up period up to 3 years.

Based on the present data, a more restrictive regimen consisting of a 1-day dose of prophylactic antibiotic in conjunction with routine implant procedures is recommended.

The result from the present study suggests that a simplified operatory setup does not affect the survival rate of oral implant treatment.
