Abstract

Background: Dental implants are becoming a popular treatment of choice. Immediate implant placement with immediate loaded full-arch fixed dental prostheses (IPILFFDP) presents an attractive solution for edentulous and partially edentulous patients because of its high success rate, reduction in overall treatment time, and improved esthetics. However, whether it can minimize the risk of temporomandibular disorder (TMD) has not been previously studied.

Objective: To quantitatively evaluate the temporomandibular joint (TMJ) morphology changes before and after IPILFFDP, using cone beam computed tomography (CBCT).

Methods: Twelve participants without TMJ symptoms undergoing IPILFFDP were included in the study. Preoperative and 1-year postoperative assessment of CBCT scans were performed on 18 items related to TMJ and vertical dimensions. Mimics software was used for data analysis. T-test, Pearson, and Spearman correlation analyses were performed.

Results: There were no significant differences in bilateral joints between pre and post IPILFFDP. Compared with pre-treatment CBCT, post-treatment CBCT showed a significant increase in posterior joint space. There was an approximately 2 mm increase in the vertical dimension after IPILFFDP, which is correlated with an increase in the medial joint space.

Conclusions: For patients without TMJ-related signs and symptoms, the IPILFFDP could keep the neuromuscular memory of patient's facial muscles and occlusion, and use adapted centric posture as a guide, which led to more precise restoration of the original jaw position and may shed light in future related clinical studies.

颞下颌关节形态变化的 CBCT 研究：即刻植入种植体和即刻装入全拱形固定义齿。

背景：种植牙正成为一种流行的首选治疗方法。即刻种植体植入即刻加载全口固定义齿（IPILFFDP）因其高成功率、缩短整体治疗时间和改善美观等优点，为无牙和部分无牙患者提供了一种极具吸引力的解决方案。然而，它是否能最大限度地降低颞下颌关节紊乱症（TMD）的风险，以前还没有研究过：使用锥形束计算机断层扫描（CBCT）定量评估 IPILFFDP 前后颞下颌关节（TMJ）形态的变化：研究纳入了 12 名无颞下颌关节症状、接受 IPILFFDP 的患者。对颞下颌关节和垂直尺寸相关的 18 个项目进行术前和术后 1 年 CBCT 扫描评估。使用 Mimics 软件进行数据分析。进行了 T 检验、Pearson 和 Spearman 相关性分析：结果：IPILFFDP治疗前后双侧关节无明显差异。与治疗前的 CBCT 相比，治疗后的 CBCT 显示后关节间隙明显增加。IPILFFDP 治疗后的垂直尺寸增加了约 2 毫米，这与内侧关节间隙的增加有关：结论：对于没有颞下颌关节相关症状和体征的患者，IPILFFDP 可以保持患者面部肌肉和咬合的神经肌肉记忆，并以适应的中心姿势为指导，从而更精确地恢复原有的下颌位置，这可能会为今后的相关临床研究提供启示。
