To describe the proportions of different osseous diagnoses in older patients with temporomandibular disorders (TMD) and to analyze the symptoms, disc position, occluding pairs, and facial skeletal characteristics of patients with bilateral osteoarthrosis (BOA) and bilateral normal joints (BNJ).
This retrospective cross-sectional study constituted 88 older patients (age ≥60 years). The osseous diagnosis, symptoms, disc position, occluding pairs, and facial skeletal characteristics were evaluated. Variables in BOA patients and BNJ patients were compared using the -test and chi-square test.
Forty-eight patients had BOA, 7 had unilateral osteoarthrosis, 11 had intermediate osteoarthrosis, and 22 had BNJ. The prevalence of disc displacement without reduction (DDw/oR) in BOA patients was significantly higher than in BNJ patients. BOA patients exhibited greater ANB angle, PP-MP, U1-NPo, L1-NPo, and facial convexity angle; shorter posterior cranial base; and decreased ramus height.
BOA patients with associated DDw/oR had more complaints of orofacial pain and exhibited a shorter posterior cranial base, and greater mandibular retrusion, anterior tooth protrusion, and protruded profile than BNJ patients.
描述老年颞下颌关节紊乱病（TMD）患者不同骨质诊断的比例，并分析双侧骨关节炎（BOA）和双侧正常关节（BNJ）患者的症状、盘位置、咬合对以及面部骨骼特征。
这项回顾性横断面研究纳入了88例老年患者（年龄≥60岁）。评估骨质诊断、症状、盘位置、咬合对以及面部骨骼特征。使用t检验和卡方检验比较BOA患者和BNJ患者的变量。
48例患者患有BOA，7例患有单侧骨关节炎，11例患有中度骨关节炎，22例患有BNJ。BOA患者中不可复性盘移位（DDw/oR）的患病率显著高于BNJ患者。BOA患者表现出更大的ANB角、PP-MP、U1-NPo、L1-NPo和面部凸度角；后颅底较短；下颌支高度降低。
与BNJ患者相比，伴有DDw/oR的BOA患者有更多口面部疼痛主诉，后颅底较短，下颌后缩、前牙前突和凸面型更明显。
