The goal of this study was to quantify the amount of bone graft material present in the anterior part of ascending ramus while avoiding the inferior alveolar neurovascular bundle injury.
This study was made on 16 samples of dry skull. Osteotomies were made in front of the mandibular canal from the mandibular notch to 3 mm posterior of the root of the third molar. The dimensions, the surface area, and the volume of the bone grafts were measured and evaluated.
The average dimensions of the graft material obtained from the anterior part of ascending ramus were 37.60 x 33.17 x 22.48 x 9.15 mm; the average bone volume was 2.36 mL; and the average surface area of the graft material was 495.13 mm(2).
The results of the present study show that the anterior part of ascending ramus can be used as the donor site for reconstruction of small bone defects in the oral and maxillofacial region.
本研究的目的是量化升支前部存在的骨移植材料的量,同时避免下牙槽神经血管束损伤。
本研究对16个干燥颅骨样本进行。在下颌管前方,从下颌切迹至第三磨牙牙根后方3毫米处进行截骨术。测量并评估骨移植的尺寸、表面积和体积。
从升支前部获得的移植材料的平均尺寸为37.60×33.17×22.48×9.15毫米;平均骨体积为2.36毫升;移植材料的平均表面积为495.13平方毫米。
本研究结果表明,升支前部可作为口腔颌面部小骨缺损重建的供区。
