Abstract

This study examined the effects of periodontal disease on implants placed simultaneously with adjacent periodontal surgery through an evaluation of the survival rate, success rate, and marginal bone loss of the implants. In total, 11 implants were placed in nine patients. Regenerative surgery including guided tissue regeneration was performed in eight patients. Resective flap curettage (open flap debridement) was performed in three patients. Seven of the eleven teeth that underwent periodontal surgery were extracted, and the remaining four survived for an average of 6 years and 6 months during follow-up. Two implants failed during the follow-up period. Except the two failed implants, the mean survival period was 94 months and the success and survival rates were 90.9% each. Moreover, the mean marginal bone loss of the survived implants was 0.14 mm. The prognosis of implants placed simultaneously with periodontal surgery of the adjacent natural teeth with periodontitis is reasonable.
