CBCT评估上颌磨牙腭侧牙槽嵴骨突的可行性分析

Feasibility Analysis of CBCT Evaluation of the Alveolar Ridge Bony Prominence on the Pal-atal Side of Maxillary Molars

摘要: 近年来，对牙周疾病的治疗目标有了显著的改变，不再只强调控制牙周感染炎症和改善功能，而逐步转向更注重口腔“粉白美学”的方向。在牙周整形和种植手术中，软组织移植发挥着重要的作用，尤其是以自体组织移植物为基础的牙周膜龈手术。膜龈手术在美学和功能重建中发挥着关键的作用，尤其在改善牙龈形态、解决牙龈退缩等问题方面。然而，在实际的临床操作中，涉及到软组织缺损位点和个体上腭供区的情况存在差异，需要根据患者的具体情况，个体差异，以及手术的目标来制定个性化的治疗方案，以达到最佳的临床效果。以一个例子来说，有些患者的上颌磨牙腭部牙槽嵴上可能存在骨性突起，这可能会对牙周手术的实施产生影响。随着锥形束计算机断层扫描(CBCT)在口腔临床中的广泛应用，它已成为常用的检查手段，能够进行头颅部全面、多角度的观测。在本文中，我们将对已有的CBCT对上颌磨牙腭侧相关指标测量的研究进展进行综述，并同时探讨CBCT在评估上颌磨牙腭侧牙槽嵴骨突可行性方面的发展。

Abstract: In recent years, the treatment goal of periodontal disease has developed from the single emphasis on the control of inflammation and improvement of function to the further shaping of oral “whiten-ing aesthetics”, and soft tissue transplantation is an important part of periodontal plastic and im-plant surgery. Periodontal ligament and gingival surgery based on autologous tissue transplanta-tion has predictability and long-term stability. It has also been widely used in aesthetic prostho-dontics of the oral cavity. However, the site of soft tissue defect and the donor site of the palate are different in clinical practice, which leads to a change in the operative procedure. Some patients have bony protrusions on the palatal alveolar ridge of their maxillary molars, which may affect perio-dontal surgery in these patients. CBCT has become a commonly used examination method in vari-ous oral clinical disciplines. It can be used to observe the skull from all angles and has a high clinical acceptance. In this article, we reviewed the research progress of CBCT in palatal measurement of maxillary molars and the feasibility of CBCT in evaluating palatal alveolar protuberance of maxillary molars.
