摘要
目的探讨锥形束CT(cone beam computer tomography,CBCT)引导下微创拔除前磨牙区多生牙的临床效果,为临床拔除前磨牙区多生牙提供经验参考。方法收集CBCT定位下使用种植机微创拔除前磨牙区多生牙的病例,分析多生牙的上、下颌分布情况、位置特点、手术时间及拔牙术后反应等情况。结果前磨牙区多生牙中下颌占70.13%,埋伏位置偏舌(腭)侧者占89.61%,手术平均时间上颌(26.96±7.60)min,下颌(27.70±7.35)min,术后疼痛视觉模拟评分为术后1 d[上颌(2.48±0.90)分,下颌(2.54±0.98)分],术后7 d[上颌(0.57±0.51)分,下颌(0.59±0.53)分]。结论前磨牙区多生牙以偏舌腭侧最为常见(89.61%);CBCT引导下使用种植机拔除前磨牙区多生牙时间较短,手术创伤较小。
Objective To investigate the clinical outcomes of minimally invasive extraction of supernumerary teeth in premolar region under Cone beam Computer Tomography(CBCT)guidance,and provide reference concerned.Methods Patients with supernumerary teeth in premolar region and accepted the tooth extraction by oral implant machine under the guidance of CBCT were collected.The distribution of supernumerary teeth in upper and lower jaw,position characteristics,operation duration and postoperative reaction were analyzed.Results The ratio of supernumerary teeth located in the mandible of premolar region was 70.13%.Supernumerary teeth impacted on the lingual(palatal)side has accounted for 89.61%.The average operation time of supernumerary teeth in maxilla was(26.96±7.60)min,and in mandible was(27.70±7.35)min.Visual Analogue Scale(VAS)score was respectively(maxilla 2.48±0.90,mandible 2.54±0.98)one day after extraction and(maxilla 0.57±0.51,mandible 0.59±0.53)seven days after extraction.Conclusion Supernumerary teeth in premolar region are always impacted in the lingual side(89.61%).Combined application of CBCT and implantology surgical unit can not only reduce the operation time of extracting supernumerary teeth located in premolar region,but also reduce the trauma and postoperative complications.
