The extraction of maxillary impacted teeth is a common procedure in oral surgery, frequently complicated by oroantral communications. For less-experienced clinicians, accurately assessing the difficulty and associated risks of maxillary third molar extractions remain a significant challenge.
We present a case involving disparate outcomes following bilateral extraction of maxillary third molars. Using cone-beam computed tomography and three-dimensional software, we conducted a digital assessment of the factors contributing to extraction difficulty and risk, controlling for potential confounders. Key variables analyzed included alveolar bone volume, bone quality, crown-root angulation, and maxillary sinus mucosal thickness. Additionally, we introduce the novel concept of "tegmen bone" to quantitatively evaluate the bone mass between the teeth and the maxillary sinus. This unique case, with differing outcomes on opposite sides of the same patient, provided an opportunity to minimize extraneous variables and focus on the local anatomical factors influencing the procedures, thereby improving the precision of our analysis.
This case highlights the potential utility of predictive analysis in guiding the management of complex tooth extractions.
上颌阻生牙拔除是口腔外科的常见手术,常因口腔上颌窦交通而复杂化。对于经验不足的临床医生而言,准确评估上颌第三磨牙拔除的难度和相关风险仍是一项重大挑战。
我们呈现了一例双侧上颌第三磨牙拔除后出现不同结果的病例。使用锥形束计算机断层扫描和三维软件,我们对导致拔牙难度和风险的因素进行了数字评估,同时控制潜在的混杂因素。分析的关键变量包括牙槽骨体积、骨质量、冠根角度和上颌窦黏膜厚度。此外,我们引入了“骨板骨”这一新颖概念,以定量评估牙齿与上颌窦之间的骨量。这一独特病例,即同一患者双侧结果不同,提供了一个机会来尽量减少无关变量,并专注于影响手术的局部解剖因素,从而提高我们分析的准确性。
本病例凸显了预测分析在指导复杂牙齿拔除管理中的潜在效用。
