目的:研究294例维吾尔族患者下颌阻生智齿不同萌出情况与拔牙术后并发症之间的关系。方法:根据长期临床观察及294例拔牙病例记录资料并进行分析。结果:在根尖发育已完成的294例中,近中阻生占48.3%(142例),其次为垂直阻生及水平阻生,各占25.2%(74例)及24.1%(71例),舌向位少见,占2.4%(7例)。在294例中,水平位拔牙后并发症最多见,占49.3%,舌向位最少,占14.3%。结论:拔牙时应根据牙齿位置,牙位高低,牙根及根尖形态,邻牙情况等来选择适当拔牙方法,预防术后并发症。 Objective: To study the relationship between different eruptions of mandibular impacted wisdom teeth and complication after extraction in 294 Uygur patients. Methods: According to long-term clinical observation and 294 cases of tooth extraction records and analysis. Results: Of the 294 cases with apical development, 48.3% (142 cases) had proximal and proximal obstruction, followed by vertical and horizontal occlusion (25.2% and 74.1%, respectively) and 24.1% (71 cases) , The tongue is rare, accounting for 2.4% (7 cases). In 294 cases, the complications after horizontal extraction were the most common, accounting for 49.3%, with the least tongue orientation, accounting for 14.3%. Conclusion: Extraction of teeth should be based on the location of teeth, the level of teeth, root and apical form, adjacent teeth, etc. to select the appropriate extraction method to prevent postoperative complications.
