Abstract

Bone grafting is a surgical procedure aimed at implanting graft material in alveolar bone defects or resorption cases to provide sufficient volume for the placement of dental implants. The techniques used to modify the dimensions of resorbed alveolar bone have varied and have included the use of autogenous, allogenic, or synthetic bone grafts, along with resorbable and non-resorbable membranes.

Due to the instability of the bone graft material and its displacement to adjacent tissues, as well as the need for mechanical support from membranes and screws, and the invasive surgical procedures necessary to increase bone volume, this study aims to investigate the extent of vertical bone gain using a locally made synthetic bone graft composed of calcium phosphate cement (monetite) combined with collagen using the subperiosteal tunnel technique.

The study sample consisted of 12 patients from the Department of Oral and Maxillofacial Surgery at Tishreen University Hospital, all of whom suffered from bone loss. All patients underwent clinical and radiographic examinations using CBCT technology to analyze the structural dimensions in the area of bone loss and to measure the dimensions before grafting, after 4 months, and after 6 months.

In the mandible, measurements were taken from the upper edge of the alveolar canal to the apex of the bone, while in the maxilla, measurements were taken from the apex of the bone to the floor of the maxillary sinus or the buccal cavity depending on the area of bone loss. The average increase in the length of the alveolar ridge after 4 months was 1.09, which was statistically significant. However, the increase after 6 months was 0.91, which was not statistically significant, with a substantial difference of 0.81 between the increase measured after 4 months and after 6 months.

We conclude that the use of the subperiosteal tunnel technique for bone augmentation is a minimally invasive surgical procedure that allows access to the alveolus while preserving the integrity of the periosteum, thereby reducing swelling and postoperative complications. This technique provides the potential for vertical bone gain after only 4 months, while after 6 months, the gain was not statistically significant.
