方法

以描述性研究的方法，回顾2020年1月至2023年6月在空军军医大学口腔医院正畸科就诊的骨性Ⅱ类错

板联合正畸正颌治疗。比较治疗前后患者的头影测量参数，评价患者面型改善情况；同时比较治疗前后患者髁突高度和骨密度变化，评估患者骨质改建的影响。

结果

完成治疗后6个月，患者的各项硬、软组织参数较治疗前1个月趋于正常，除ANS-Me/N-Me和Pg-Pg′外，其余如SNA、SNB、ANB角等各项治疗前后指标差异均有统计学意义(

＜0.05)。与治疗前1个月相比，所有患者治疗6个月后的髁突高度无显著变化，髁突最前点、顶点和最后点的骨密度均普遍增加，差异有统计学意义(

0.01)。

结论

对骨性Ⅱ类错

Abstract

Objective

To investigate the efficacy of stabilization splint combined with orthodontic and orthognathic treatment on the patients of type Ⅱ bone malocclusion with condylar resorption by observing the changes in soft and hard tissues and condylar process in order to provide reference for combined therapy technology.

Methods

A descriptive research was performed on 13 patients with type Ⅱ bone malocclusion with condylar resorption admitted in our department from January 2020 to June 2023. Their clinical data were collected and analyzed retrospectively. They were 3 males and 10 females

with an age ranging from 18 to 27 years (average 21.769±3.032 years). All of them have received stabilization splint combined orthodontic and orthognathic treatment. The cephalometric parameters before and after treatment were compared to evaluate the improvement of appearance. The changes in condylar height and condylar bone density were observed and compared before and after treatment to evaluate the bone remodeling of the patients.

Results

In 6 months after treatment

the parameters of soft and hard tissues were in a trend of normal levels when compared with those in 1 month before treatment. Except for ANS-Me/N-Me and Pg-Pg′

there were significant differences in the indicators such as SNA

SNB and ANB angles before and after the treatment (

0.05). No significant change in condyle height was observed between the above 2 time points (

0.05). But the condylar bone density of the most anterior point

vertex

and the last point were generally increased between the 2 time points (

0.01).

Conclusion

Stabilization splint combined with orthodontic and orthognathic treatment shows significant and stable clinical efficacy in the patients of type Ⅱ bone malocclusion with condylar resorption. It can effectively relieve joint symptoms and meet patients' requirements for facial beauty.
