PRESERVATION OF MANDIBULAR ALVEOLAR BONE RIDGE BY USING BIOACTIVE GLASS FOLLOWING TEETH EXTRACTION (CLINICAL STUDY)

Abstract

Alveolar bone resorption is a common finding after teeth extraction, It creates an aesthetic and retentive problems for the fabrication of the conventional prosthesis, or it can make the placement of endosseous implant difficult or even impossible<l). Several materials were tried to augment resorbed ridges to solve this problem. The aim of our study was to evaluate the effectiveness of bioactive glass as a bone graft material for ridge preservation. This study were composed of twelve patients were selected free from any relevant diseases may affect the study or contra-indicated for surgical intervention, the patients were totally maxillary edentulous, and indicated for clearance of lower anterior teeth, for construction of complete denture. These patients divided into two groups each six patients as study and control groups. Preoperative panoramic X-rays and upper and lower impressions were taken to all patients. In both groups the patients were locally anaesethised, atraumatic extraction of lower anterior teeth were done, envelop flaps were performed, interseptal bone was removed, followed by green stick fracture to the labial plate ofbone and tilted lingually, sharp edges were trimmed, for the control group closure of the wound was done by 3-0 silk continuous suture. In study group blood samples were taken from study group patient, mixed with bioactive glass in dappen dish, introduction of the prepared material is performed between labial and lingual plate of bone, closure of the wound were done by using 3-0 silk continuous suture.
