Long-term studies have indicated that alloplastic bone grafts composed of nonresorbable hydroxyapatite (NHA) are clinically stable and safe. However, our previous report suggested that NHA grafts may be an etiological factor for recurrent periodontitis in the absence of supportive periodontal treatment (SPT). We removed infected NHA from the root surface by flap surgery in two cases of recurrent periodontitis. After removal of the infected NHA, the inflammation subsided in these cases and they were clinically stable for several years. (J Oral Sci 51, 659-663, 2009)
