牙根拔除术是牙槽外科门诊最常见的手术操作,但由于口腔解剖结构的复杂性和操作空间的有限性常常造成术区软、硬组织不同程度的损伤,特别是在操作不正规的情况下,易引起局部出血、疼痛、牙折、邻牙损伤等并发症。所以,在正规操作的前提下,选择合适的手术方式是牙根拔除术成功的关键。临床中作者发现,部分残根区域由于牙冠缺失时间较长,邻牙移位,牙间隙减小,致使牙根拔除的空间不足,拔除困难。通常,此类残根既可以通过挺拔法拔除,又可以采用分割 Tooth root extraction is the most common operation in alveolar surgery, but due to the complexity of oral anatomy and the limited space of operation, it often leads to different degrees of soft tissue and soft tissue injury, especially in the case of irregular operation , Easily lead to local bleeding, pain, tooth, adjacent tooth injury and other complications. Therefore, under the premise of regular operation, the choice of the appropriate surgical approach is the key to successful root extraction. Clinical authors found that part of the residual root zone due to a longer period of missing crown, adjacent teeth shift, reducing interdental space, resulting in insufficient space for root removal, removal difficulties. Often, such stubs can either be extracted by upright or split
