Hyperdontia is a disorder of odontogenesis characterised by excess teeth. Many complications can be associated with supernumerary teeth, such as crowding, tooth displacement, diastema, deep caries, retention or impaction, delayed eruption or ectopic eruption of adjacent teeth, aesthetic problems, neuralgic manifestations, root resorption of adjacent teeth, and dentigerous cyst formation with significant bone destruction. Treatment of hyperdontia depends on the area and number of supernumerary teeth, and also on the presence of pathologic processes that can affect them and/or the teeth of the normal series that could be erupted, retained or impacted.
The present case report describes the clinical management of two impacted supernumerary teeth, which impeded the eruption of the maxillary right central incisor in a paediatric patient. A multidisciplinary treatment approach was planned, including the surgical removal of the supernumerary teeth and the orthodontic correction of the unerupted permanent maxillary right central incisor. Combined surgical and orthodontic treatment resulted in an aesthetically pleasant and balanced occlusion. Thus, early multidisciplinary treatment is required for greater hard and soft tissue preservation.
多生牙是一种牙胚发育异常疾病，其特征为牙齿数量过多。多生牙可引发多种并发症，如牙齿拥挤、移位、间隙、严重龋齿、滞留或阻生、相邻牙齿萌出延迟或异位萌出、美观问题、神经痛表现、相邻牙齿牙根吸收以及含牙囊肿形成并伴有明显骨质破坏。多生牙的治疗取决于多生牙的部位和数量，还取决于是否存在可能影响多生牙和/或正常序列中可能萌出、滞留或阻生牙齿的病理过程。
本病例报告描述了一名儿科患者中两颗阻生多生牙的临床处理情况，这两颗多生牙阻碍了上颌右侧中切牙的萌出。制定了多学科治疗方案，包括手术拔除多生牙以及对上颌右侧未萌出的恒中切牙进行正畸矫治。手术与正畸联合治疗实现了美观且咬合平衡的效果。因此，为了更好地保存软硬组织，需要早期进行多学科治疗。
