Abstract the aim of this study is to assess the use of beta-tricalcium phosphate only as particulate bone graft material in alveolar ridge splitting in posterior mandible versus alveolar ridge splitting without grafting material of horizontally deficient posterior mandible. Materials and Methods: this study was held in the outpatient clinic in oral implantology department, faculty of dentistry, Cairo University. This study was done on ten different operations sites on five female patients. The five patients suffered from teeth loss in posterior mandible which were horizontally deficient. These five female patients weren’t heavy smokers, pregnant, had systemic diseases that would affect normal healing. Panoramic radiographic examination and CBCT were done to the five female patients. The patients were randomly divided in to two groups where ridge split mouth technique was done. One group received Beta tricalcium phosphate (BTCP) as a grafting material, the second group received no grafting material. Both radiographic and histological assessment were done. Bucco-lingual bone width gain were measured in Mm by CBCT preoperatively, and immediately after surgery, and after 6 months in re-entry stage (second stage surgery). For each group the amount of horizontally bone gain after 6 months measured in Mm were subtracted from the amount of horizontally bone gain achieved immediately after surgery (primary outcome). A core biopsy were taken after 6 mounts in re-entery stage by surgical bur, and histopathological examination was done to detect bone quality for each group. Results: For Radiographic assessment results, group 1 was higher in bone gain at 2mm than group 2 and was statistically different than group 2. group 1 was higher in bone gain at 5mm than group 2 and was statistically different than group 2. group 1 was higher in bone gain at 10mm than group 2 and was statistically different than group 2. For histopathological assessment results, group 1 was higher in the area percent of compact bone formation than group 2 and was statistically different than group 2 |
