摘要

目的:本研究的目的是明确在接受正颌手术和正畸治疗的牙骨III类错颌患者前区是否存在中远端牙齿尺寸差异,并评估前路博尔顿比与牙骨头侧测量的关系。方法:对113例非生长期患者(女54例,男59例;平均年龄:19.96±4.42岁)的牙骨骼III类错颌患者均接受了正颌手术和正畸治疗。使用精确到0.01 mm的数字卡尺从牙模上测量6颗前牙的中远端宽度,并计算前路博尔顿比。侧位头像数字化,用于测量4个骨骼和4个牙齿参数。结果:III类手术患者的平均前路比值为80.1%,标准差为2.8%。40.7%的患者前牙尺寸差异显著(大于±2个标准差),97.8%的患者下颌前牙过多。前路波顿比值与头侧测量无显著相关性。结论:临床医生在III类手术患者的诊断和治疗计划中应考虑牙齿大小差异的可能性,并在术前正畸治疗中采取措施消除这些差异。

Anterior Tooth Size Discrepancy in Class III Surgical Patients.

Objective: The purpose of the present study was to specify whether there are mesiodistal tooth size discrepancies in the anterior region in patients with dentoskeletal Class III malocclusion who underwent orthognathic surgery and orthodontic treatment and to assess the relationship between anterior Bolton ratio and dentoskeletal cephalometric measurements.

Methods: The diagnostic dental casts and lateral cephalometric radiographs of 113 nongrowing patients (54 females and 59 males; mean age: 19.96 ± 4.42 years) with dentoskeletal Class III malocclusion who underwent orthognathic surgery and orthodontic treatment were included in the study. The mesiodistal widths of the 6 anterior teeth were measured from dental casts using a digital caliper accurate to 0.01 mm and anterior Bolton ratios were calculated. Lateral cephalograms were digitalized and used to measure 4 skeletal and 4 dental parameters.

Results: The mean anterior ratio of Class III surgical patients was 80.1% with a standard deviation of 2.8%. Clinically significant anterior tooth size discrepancies (greater than ±2 standard deviation) were found in 40.7% of the sample, 97.8% of those patients having anterior mandibular tooth excess. No significant correlation was found between the anterior Bolton ratio and cephalometric measurements.

Conclusion: Clinicians should consider the probability of tooth size discrepancy in the diagnosis and treatment planning of Class III surgical patients and should perform interventions to eliminate these discrepancies during presurgical orthodontic treatment.
