title: [Clinical evaluation of synthetic hydroxyapatite implants for human periodontal osseous defects. 6 cases studied more than 3 years after the surgery].
abstract: We applied of granular hydroxyapatite HAP to periodontal bone defects, for the purpose of restoring the periodontal tissue destroyed by periodontal disease, the subjects were 6 patients (6 regions) with chronic marginal periodontitis who had passed more than 3 years since HAP implantation. After routine periodontal initial treatment, a flap operation was performed, and granular HAP, or a combination of granular and block-like HAP, was implanted into the periodontal bone defect. Clinical parameters were probing depth, clinical attachment level, clinical gingival margin, residual HAP volume and X-ray before operation, at 3, 6, 12 months, and 2, 3, and 4, 6 years after the operation. The results revealed that all measured values showed good results for both granular HAP and the combination of granular and block-like HAP after implantation, and that all cases showed stable results from 12 months on. No remarkable difference was noted between the implanted regions.
