摘要

目的:本临床研究的目的是评估使用鹿特丹腭牵张器治疗上颌横向缺陷(MTD)的骨骼成熟成年患者的硬组织变化,并分别使用x线片和牙科研究模型获得在经腭牵张期间发生的横向骨和牙齿变化。方法:采用鹿特丹腭牵张器(Rotterdam Palatal牵张器,RPD)治疗10例成年MTD患者。术前(T0)、巩固期结束3个月(T1)、固位期结束6个月(T2)分别获得牙体研究模型、后前位(PA)和侧位脑电图。所得资料的统计分析采用配对“T”检验。采用双“尾”检验来确定在牙科研究模型和x线片上观察到的变化的显著性。结果:研究模型测量结果显示,中切牙间宽度(+ 4.12 mm)、犬齿间宽度(+ 5.23 mm)、第一前磨牙间宽度(+ 5.62 mm)和第一磨牙间宽度(+ 5.11 mm)显著增加。PA脑电图测量结果显示,有效鼻腔宽度(+ 3.89 mm)、上颌骨宽度(+ 4.51 mm)和末磨牙宽度(+ 5.15 mm)显著增加。侧位脑电图测量结果显示,SNA升高(+ 0.90),SNB降低(- 0.70),ANB升高(+ 1.60),SN-Go-Gn升高(+ 2.80),具有统计学意义。结论:手术辅助快速上颌扩张术是治疗骨骼成熟个体MTD的一种成熟方法。在我们的研究中,骨载牵张器在实现上颌扩张方面的效果已经得到了临床和影像学的证实。

Evaluation of Hard Tissue Changes in Skeletally Matured Patients with Maxillary Transverse Discrepancy Treated by Rotterdam Palatal Distractor.

Objective: The aim of this clinical study was to evaluate the hard tissue changes in skeletally mature adult patients with maxillary transverse deficiency (MTD) managed using Rotterdam Palatal Distractor and to access bony and dental changes that occur in transverse plane during transpalatal distraction using radiographs and dental study models, respectively.

Methods: Ten adult patients with MTD were treated with a Rotterdam Palatal Distractor (RPD). Dental study models, postero-anterior (PA) and lateral cephalograms were obtained pre-operatively (T0), at the end of consolidation period of 3 months (T1) and after six months into retentive phase (T2). The statistical analysis of the obtained data was analyzed using paired 'T' test. Two-'tailed' tests were applied for getting significance of changes observed on dental study models and radiographs.

Results: The study model measurements illustrated statistically significant increase in inter-central incisor width (+ 4.12 mm), inter-canine width (+ 5.23 mm), inter-first premolar width (+ 5.62 mm) and inter-first molar width (+ 5.11 mm). The PA cephalogram measurements demonstrated statistically significant increase in effective nasal cavity width (+ 3.89 mm), skeletal maxillary width (+ 4.51 mm) and inter-last molar width (+ 5.15 mm). The lateral cephalogram measurements demonstrated statistically significant increase in SNA (+ 0.90), decrease in SNB (- 0.70), increase in ANB (+ 1.60) and increase in SN-Go-Gn (+ 2.80).

Conclusions: Surgically assisted rapid maxillary expansion is an established procedure for the management of MTD in skeletally mature individuals. The efficacy of bone-borne distractors in achieving maxillary expansion has been confirmed clinically and radiologically in our study.
