Abstract

Objectives: This study aims to assess the stability of soft tissues one and three years after orthognathic mandibular advancement surgery by superimposing the cone-beam computed tomography (CBCT) images and quantifying potential soft tissue changes following surgery.

Materials and methods: In this prospective observational study, changes in the hard and soft tissues of the chin, lower incisors, and lower lip due to displacement and/or bone remodeling were analyzed using three-dimensional models based on CBCT superimposition images acquired before surgery (T0), one year after surgery (T1), and three years after surgery (T3). The cranial base was used as a reference for the superimpositions, which were based on fully automated grayscale voxel-wise registrations.

Results: The soft chin showed more than 2 mm displacement between T0 and T1 and between T0 and T3, along with hard chin displacement. The lower lip had less displacement at T0 and T1. The soft tissue adaptation between T1 and T3 indicates stability of the soft tissue correction.

Conclusion: Even though the soft tissue three-dimensional response one year after surgery was variable, the investigated anatomical regions were stable between one- and three years post-surgery, and only the soft chin exhibited some relapse. The soft tissue chin changes observed were strongly correlated with the hard chin.

Clinical relevance: This study provides comprehensive and long-term insights considering soft tissue facial features' stability after orthognathic surgery, impacting orthodontic treatment planning, and integrating both problem-oriented and goal-oriented approaches. The outcomes emphasize the importance of surgical aesthetics alongside occlusion, ultimately contributing to better long-term results and enhanced patient satisfaction.

下颌正颌前移矫正II类错牙合后软组织稳定性的三维长期评估。
目的:本研究旨在通过锥形束计算机断层扫描(CBCT)图像的叠加和量化手术后潜在的软组织变化,评估正颌前移手术后1年和3年的软组织稳定性。材料与方法:本前瞻性观察研究基于术前(T0)、术后1年(T1)和术后3年(T3)采集的CBCT叠加图像,采用三维模型分析下颌、下门牙和下唇因移位和/或骨重塑引起的软硬组织变化。颅底被用作重叠的参考,这是基于全自动灰度体素配准。结果:软下巴在T0 ~ T1、T0 ~ T3间移位大于2mm,硬下巴同时移位。下唇在T0和T1时位移较小。T1和T3之间的软组织适应表明软组织矫正的稳定性。结论:尽管术后1年软组织的三维反应是可变的,但术后1 - 3年所研究的解剖区域是稳定的,只有软下巴有一定的复发。观察到的软组织下巴变化与硬下巴密切相关。临床意义:本研究综合考虑了正颌手术后软组织面部特征的稳定性,影响正畸治疗计划,整合了问题导向和目标导向的方法,提供了全面和长期的见解。结果强调手术美学与闭塞的重要性,最终有助于更好的长期结果和提高患者满意度。

期刊介绍: The journal Clinical Oral Investigations is a multidisciplinary, international forum for publication of research from all fields of oral medicine. The journal publishes original scientific articles and invited reviews which provide up-to-date results of basic and clinical studies in oral and maxillofacial science and medicine. The aim is to clarify the relevance of new results to modern practice, for an international readership. Coverage includes maxillofacial and oral surgery, prosthetics and restorative dentistry, operative dentistry, endodontics, periodontology, orthodontics, dental materials science, clinical trials, epidemiology, pedodontics, oral implant, preventive dentistiry, oral pathology, oral basic sciences and more.
