摘要

目的:研究不同数据采集方法对最终修复体设计和动态咬合形态的影响。材料和方法:数字系统允许使用口内扫描仪和光学下颌跟踪,通过数字记录功能生成路径(DRFGP)技术在口腔内记录功能咬合路径。进行了两个子研究。研究1评估了31名患有角度I级咬合的健康参与者的全弓咬合夹板,比较了虚拟关节器和下颌跟踪系统的结果。研究II评估了12名参与者的三单元固定局部假牙(fpd),比较了虚拟关节器、面部扫描和下颌跟踪的模型。此外,比较了两种颌骨跟踪系统:光学跟踪装置(OTD)和电子跟踪装置(ETD)之间的矢状和突出髁倾角和Bennett角。统计分析包括正态性检验和非参数检验,P < 0.05为显著性。结果:两组间髁突倾角测量差异有统计学意义(P < 0.01)。除中突外,侧髁倾角值显示差异。咬合夹板表面的偏差有统计学意义(P < 0.01)。对于FPDs,牙1.6表现出显著差异。结论:尽管下颌跟踪测量有显著差异,但全弓和FPD修复体对咬合设计的总体影响很小。半可调节关节器产生了与数字方法相当的结果,支持传统和数字工作流程的临床可靠性。

Impact of digital jaw tracking systems on dynamic occlusal surface morphology and condylar inclination measurements.

Impact of digital jaw tracking systems on dynamic occlusal surface morphology and condylar inclination measurements.

Purpose: This study investigated how different data collection methods affect final restoration design and dynamic occlusal morphology.

Materials and methods: Digital systems allow intraoral recording of functional occlusal paths through the digitally recorded functionally generated pathway (DRFGP) technique, using intraoral scanners and optical jaw tracking. Two substudies were conducted. Study I assessed full-arch occlusal splints in 31 healthy participants with Angle Class I occlusion, comparing outcomes from a virtual articulator and jaw tracking systems. Study II evaluated three-unit fixed partial dentures (FPDs) in 12 participants, comparing models from virtual articulators, face scans, and jaw tracking. Additionally, sagittal and protrusive condylar inclinations and the Bennett angle were compared between two jaw tracking systems: an optical tracking device (OTD) and an electronic tracking device (ETD). Statistical analysis included normality tests and non-parametric tests with significance set at P < .05.

Results: Condylar inclination measurements significantly differed between OTD and ETD (P < .01). Lateral condylar inclination values showed discrepancies, excluding mediotrusion. Occlusal splint surfaces showed significant deviations using OTD (P < .01). For FPDs, tooth 1.6 exhibited notable differences.

Conclusion: Despite significant differences in jaw tracking measurements, the overall impact on occlusal design for both full-arch and FPD restorations was minimal. Semi-adjustable articulators produced comparable outcomes to digital methods, supporting the clinical reliability of both conventional and digital workflows.

期刊介绍: This journal aims to convey scientific and clinical progress in the field of prosthodontics and its related areas to many dental communities concerned with esthetic and functional restorations, occlusion, implants, prostheses, and biomaterials related to prosthodontics. This journal publishes • Original research data of high scientific merit in the field of diagnosis, function, esthetics and stomatognathic physiology related to prosthodontic rehabilitation, physiology and mechanics of occlusion, mechanical and biologic aspects of prosthodontic materials including dental implants. • Review articles by experts on controversies and new developments in prosthodontics. • Case reports if they provide or document new fundamental knowledge.
