Study design:

Cross-sectional 

研究目的:

通过获取咬合重建患者的术前检查结果(包括影像学资料、临床病历、临床照片等)、治疗过程(包括咬合重建的流程、治疗过程照片等)、术后检查结果(包括术后临床照片、随访过程的临床病历和影像学资料等),利用CBCT三维模型重建测量咬合重建中咬合垂直距离升高前后颞下颌关节结构变化,对比咬合重建前后颞下颌关节临床表现,评估咬合垂直距离升高对颞下颌关节的影响,为咬合重建时咬合垂直距离的选择提供参考。  

Objectives of Study:

Obtain preoperative examination results of patients undergoing occlusal rehabilitation (including radiographic data, clinical medical records, clinical photographs, etc.), the treatment process (including the procedures of occlusal reconstruction, photographs of the treatment process, etc.), and postoperative examination results (including postoperative clinical photographs, clinical records, and radiographic data from follow-up visits, etc.). Utilize CBCT for three-dimensional model reconstruction to measure the structural changes in the temporomandibular joint (TMJ) before and after the increase in vertical dimension of occlusion during occlusal rehabilitation. Additionally, compare the clinical manifestations of the TMJ before and after occlusal rehabilitation to assess the impact of the increase in vertical dimension of occlusion on the TMJ, and provide a reference for the selection of vertical dimension of occlusion during occlusal rehabilitation.

测量指标:

Outcomes:

指标中文名:

髁突形态

指标类型:

次要指标

Outcome:

Condylar morphology

Type:

Secondary indicator

测量时间点:

治疗前及治疗后

测量方法:

分为扁平形、鸟嘴形和卵圆形三种

Measure time point of outcome:

Before and after treatment

Measure method:

The condylar morphology was divided into three categories: round, flattened, and beak-like.

指标中文名:

髁突-关节窝结构

指标类型:

Outcome:

Condyloide-articular fossa structure

Type:

Primary indicator

测量时间点:

Measure method:

指标中文名:

髁突位置

指标类型:

主要指标

Outcome:

Condylar position

Type:

Primary indicator

测量时间点:

治疗前及治疗后

测量方法:

利用关节间隙对髁突位置定性:LR=(P-A)/(P+A),其P代表关节后间隙,A代表关节前间隙。(LR<-0.325表示髁突后位;-0.325≤LR≤0.211为髁突中位;LR>+0.211为髁突前位)

Measure time point of outcome:

Before and after treatment

Measure method:

The articular space was used to characterize the condyle position: LR= (P-A) /(P+A), where P represented the postarticular space and A represented the prearticular space. (LR<-0.325 indicates posterior condylar position; -0.325≤LR≤0.211 is the median condyle; LR>+0.211 denotes anterior condylar position).

指标中文名:

髁突体积、表面积、形态学指数

指标类型:

次要指标

Outcome:

Condyle volume, surface area, morphological index

Type:

Secondary indicator

测量时间点:

治疗前及治疗后

测量方法:

3D Slicer 5.0.3软件自动生成髁突体积(V)、表面积(S),进一步计算获得髁突形态学指数:MI=V/S

Measure time point of outcome:

Before and after treatment

Measure method:

3D Slicer 5.0.3 software automatically generates condyle volume (V) and surface area (S). The morphological index of condyle was further calculated: MI=V/S.
