Clinical use of Synthograft^® in the vertical alveolar bone defects

Abstract

Eleven outpatients (twelve cases) associated with vertical bone defects bilaterally were selected for this study.
After treatment of initial preparation, the one bone defect lesion was received flap-operation with bone grafts “Synthograft^®” (test) and the another was treated only flap-operation (control) in one of the patients.
Pocket depth, attachment level and roentgenographic bone loss which was the area of the vertical bone defect surrounded by CEJ of aproximate teeth coronally were employed for the pre-and post-operative examination. And the treatment effects were evaluated between the preoperative and three and six postoperative months periods.
Results revealed that
1. In the experimental groups, the mean values for decrease of pocket depth, gain of attachment level and roentgenographic bone formation were respectively 3.5mm, 2.5mm and 6.3mm² at three months, 2.6mm, 1.4mm and 5.0mm² at six months postoperatively.
2. In control groups, the mean values for decrease of pocket depth, gain of attachment level and roentgenographic bone formation were 3.3mm, 2.3mm and -0.2mm² at postoperative three months, and 2.4mm, 1.4mm and 2.1mm² at postoperative six months respectively.
3. There was a significant difference in roentgenographic bone formation at three months postoperatively between experimental and control groups.
