Reconstruction for Vertical Bone Defects by Synthograft^® Application

A two years period observation

Abstract

Synthograft^®, a synthetic bone grafting material, mainly composed of β-tricalcium phosphate was implanted into human periodontal osseous defects. Fourteen patients, 30 to 61 years of age, were selected for this study. After initial treatment, twenty two defects were implanted with Synthograft^®. Probing depth and loss of attachment were measured at the deepest portion of the defects. Tooth mobility was evaluated and the alveolar bone formation was determined by the areas occupied by a radiopaque substance in standardized dental radiographs. These examinations were made before and 3, 6, 12, 24 months after the surgery. Among twenty two cases, two cases were excluded from this study, because these teeth were extracted at 12 months.
Mean probing depth significantly decreased from 7.0mm to 3.7mm during two years. Mean loss of attachment significantly decreased from 7.5mm to 5.1mm during two years. In some cases tooth mobility was disappeared. Radiographically, in 75% of the cases bone formation was clearly observed, provided newly formed alveolar crest, lamina dura and bony trabeculae in the implanted site.
These findings suggest that Synthograft^® is a useful graft material because of its potential for osseous repair in combination with its availability, ease of manipulation and storage advantages.
