Planning a comprehensive dental treatment should include assessment and classification of the condition of the alveolar ridge. Existing classifications are insufficient. This study aimed to investigate the frequency of bone deficiencies in the anterior mandible and to develop an extension of one of the alveolar bone dehiscence classification.
Cone-beam computed tomography scans of 100 adults with the mean age of 36.75 ± 11.77 years were analyzed. Measurements were taken from the 31. tooth.
The presence of any bone defect was found in 91 (91%) of cases. Fenestrations were detected in 9% of study images, and dehiscence were detected in 90% of study images. A thin alveolar plate of below 0.2 mm independent from the side was found in 37 (37%) of cases. The mean height of buccal fenestration was 3.10 ± 1.09 mm, and the mean height of lingual fenestration was 2.73 ± 0.91 mm. The mean height of buccal dehiscence was 4.39 ± 1.82 mm, and the mean height of lingual dehiscence was 4.27 ± 2.49 mm.
An attempt to restore the correct morphology of the alveolar process after improper treatment constitutes a therapeutic challenge. The frequent occurrence of bone deficiency prompts establishing safe treatment planning strategies, including careful assessment of the alveolar process supported by the comprehensive classification of bone defects.
全面的牙科治疗计划应包括对牙槽嵴状况的评估和分类。现有的分类方法并不完善。本研究旨在调查前下颌骨骨缺损的频率，并对一种牙槽骨开裂分类进行扩展。
对 100 名平均年龄为 36.75±11.77 岁的成年人进行锥形束 CT 扫描。从 31 号牙开始测量。
91%（91 例）的病例存在任何骨缺损。研究图像中发现 9%有裂缝，90%有开裂。37%（37 例）的病例牙槽骨板厚度小于 0.2mm，且独立于颊舌侧。颊侧开窗的平均高度为 3.10±1.09mm，舌侧开窗的平均高度为 2.73±0.91mm。颊侧开裂的平均高度为 4.39±1.82mm，舌侧开裂的平均高度为 4.27±2.49mm。
由于治疗不当而试图恢复牙槽骨的正确形态构成了治疗上的挑战。骨缺损的频繁发生促使我们建立安全的治疗计划策略，包括对牙槽骨进行全面的骨缺损分类，并仔细评估。
