目的 应用锥形束CT影像数据研究连续多颗下颌切牙之间的近远中空间,为临床下颌切牙缺失修复及种植手术方案设计提供理论依据.方法 选取 500 例患者的CBCT影像资料,对连续多颗下颌切牙间的近远中空间进行测量和统计学分析,并评估不同种植方案的可行性.结果 测量 2 颗中切牙之间近远中空间为(10.72±1.10)mm,单颗中切牙和同侧侧切牙之间近远中空间在左右侧分别为(11.33±1.00)、(11.45±0.98)mm;连续 3 颗下切牙近远中空间在左右侧分别为(15.69±1.25)、(15.79±1.26)mm;连续4 颗下切牙近远中空间为(20.76±1.48)mm.下颌切牙区各牙位区段的近远中空间有性别差异,男性均略大于女性.结论 下颌切牙区近远中空间窄小,连续 2 颗切牙缺失时仅部分患者可植入 2 枚窄径种植体,其余只能选择种植悬臂修复,当 2 颗以上下颌切牙缺失时可植入 2 枚植体,实现种植固定桥修复.
Radiological measurement and analysis of mesiodistal space at mandibular incisor positions
Objective To investigate the mesiodistal space in the area of multi-consecutive mandibular incisors,using CBCT image data,in order to provide a theoretical basis for the restoration of missing mandibular incisors and dental implant surgery.Methods CBCT imaging data of 500 patients were selected.The mesiodistal space in the area of multi-consecutive mandibular incisors were meas-ured and statistically analyzed,and the feasibility of different implant placement strategies was evaluated.Results The mesiodistal space between two mandibular central incisors was(10.72±1.10)mm,and the mesiodistal space between mandibular central and lateral incisors were(11.33±1.00)mm and(11.45±0.98)mm on the left and right sides,respectively.The mesiodistal space between three consecutive mandibular incisors were(15.69±1.25)mm and(15.79±1.26)mm on the left and right sides,respectively.The mesiodistal space between four consecutive mandibular incisors was(20.76±1.48)mm.There was a gender difference in the mesiodistal space between mandibular incisor positions,with males having slightly larger space than females.Conclusion The mesiodistal space between mandibular incisors is narrow.When two consecutive incisors are missing,only a few patients are available for two narrow di-ameter implants,while others have to choose cantilever restoration.When more than two mandibular incisors are missing,most patients are available for two narrow diameter implants,restoring with implant-supported fix partial bridges.
