目的探讨上颌第3磨牙的解剖位置特性与其并发症的关系及并发症的处理方法和拔牙操作时机.方法对1995年至2010年拔除的8 131枚上颌第3磨牙的诊治情况进行回顾性研究.结果 8 131枚上颌第3磨牙中,引起张口受限1 062例(其中冠周炎628例,颊部糜烂308例,伴颊部新生物126例),食物嵌塞2 604例,龋坏或牙周炎1 654例,无症状者2 810例.经拔牙及局部治疗后,随访1月至5 a,局部症状消除,断根残留者无异常.结论食物嵌塞、冠周炎、颊部糜烂、颊部新生物等是上颌第3磨牙的主要并发症;拔除无对颌或位置不正的上颌第3磨牙是治疗和预防由其引起的并发症的最佳有效方法.
Objective To investigate the relationship between the anatomical position of the maxillary third molar and its complications, the treatment of complications and the timing of tooth extraction.Methods The diagnosis and treatment of 831 maxillary third molar extracted from 1995 to 2010 were retrospectively studied. Results Among 8 131 maxillary third molars, 1 062 cases (including 628 cases of pericoronitis, 308 cases of cheek erosion and 126 cases of buccal neoplasms) were caused in the third molars. There were 2 604 cases of food impaction, 1 654 cases of periodontitis and 2 810 cases of asymptomatic.After tooth extraction and topical treatment, local symptoms disappeared and the residual root were normal after follow-up from 1 month to 5 years.Conclusion Food impaction, pericentritis, cheek erosion , Buccal neoplasms, etc. are the main complications of the maxillary third molars. To remove the maxillary third molars without or with malposition is the best and effective method to treat and prevent the complications caused by it.
