Proper localization of supernumerary teeth is very important for the diagnosis, treatment planning, and prior to any surgical intervention. Traditionally, supernumerary teeth were diagnosed and located using two-dimensional (2D) radiographic methods such as panoramic views, cephalometric imaging, and also intraoral (also often occlusal) radiographs. With the introduction of cone beam computed tomography (CBCT) in dental medicine, this three-dimensional (3D) imaging technique is now more and more used for the exact localisation of supernumerary teeth and the diagnosis of root resorption of adjacent teeth. Treatment planning depends on various factors such as the time of diagnosis, the age of the patient, the position of the supernumerary tooth and possible complications. In the present second part of this review article on supernumerary teeth in the maxilla and mandible, the diagnostic workflow and current treatment concepts will be presented and critically discussed.
额外牙的准确定位对于诊断、治疗计划制定以及任何手术干预之前都非常重要。传统上，额外牙是使用二维（2D）放射成像方法进行诊断和定位的，如全景片、头影测量成像以及口内（通常也是咬合）X线片。随着锥形束计算机断层扫描（CBCT）在牙科医学中的引入，这种三维（3D）成像技术现在越来越多地用于额外牙的精确定位以及相邻牙齿牙根吸收的诊断。治疗计划取决于多种因素，如诊断时间、患者年龄、额外牙的位置以及可能的并发症。在这篇关于上颌骨和下颌骨额外牙的综述文章的第二部分中，将介绍并批判性地讨论诊断流程和当前的治疗理念。
