The study on ridge preservation for implant site development

ABSTRACT

PURPOSE: The aim of this study was to investigate healed bovine bone particles (Bio-Oss(R)) and absorbable collagen sponge (CollaPlug(R)) applied extraction socket site at 4-6 months' post-extraction. MATERIAL AND METHODS: From August, 2004 to October, 2005, 17 sockets in 5 adult patients were selected out of the patients whose received ridge preservation using bovine bone particles and absorbable collagen sponges at Department of oral and maxillofacial surgery in Samsung Medical Center. There were 5 male patients, ages 30 to 58 years. Immediate postoperation and 4-6 months after operation study models were compared to evaluate the ridge dimension by measuring vertical height and horizontal width of alveolar ridge. RESULTS: The measurements at 4-6 months revealed, in the ridge dimension, a loss of vertical height of 0.91+/-0.40mm and horizontal width of 1.25+/-0.58mm. There was no adverse reaction. CONCLUSION: This study suggests that treatment of extraction sockets with graft materials and collagen sponges is valuable in preserving alveolar bone in extraction sockets and preventing alveolar ridges defects.
