摘要: 目的:探讨实现无牙颌种植固定义齿修复患者的数字化动态颌位关系转移和动态咬合调整方法。方法:无牙颌患者植入 4-6个种植体,术后即刻使用传统方法制作临时修复体,种植体植入4~6个月后,对患者拍摄锥形束CT、立体摄影测量、口内扫描和下颌运动轨迹描记。将这些数据在设计软件中进行对齐,以获得临时修复体的水平和垂直颌位关系、种植体三维位置信息、软组织信息和虚拟试戴??架的三维数据。结合个性化的下颌运动参数进行虚拟动态咬合调整,以完成最终修复。结果:患者的最终修复体实现了良好的正中和侧方咬合接触。口颌系统的组成部分,如咬合、下颌位置、关节和咀嚼肌,实现了良好的功能协调。结论:应用数字化工作流程可以准确制取无牙颌种植固定修复的印模,复制临时修复体的动态颌位关系,并对最终修复体进行动态咬合调整。修复体的咬合适应性得到了优化,并缩短了临床调整时间。

Abstract: Objective:?To explore the digital dynamic jaw position transfer and dynamic bite adjustment methods for patients undergoing fixed denture restoration with edentulous jaw implants.Methods:?Four to six implants were implanted in edentulous patients, and traditional methods were used to create temporary restorations immediately after surgery. Four to six months after implantation, cone beam CT, stereophotogrammetry, intraoral scanning, and mandibular movement trajectory recording were performed on the patients. These data were aligned in the design software to obtain the horizontal and vertical jaw position relationship of the temporary restoration, three-dimensional implant position information, soft tissue information, and three-dimensional data of the virtual trial occlusal frame. Combining personalized mandibular movement parameters with virtual dynamic bite adjustment to complete the final restoration. Results:The patient's final restoration achieved good occlusal contact in both centric and lateral positions. The components of the oral and maxillofacial system, such as occlusion, jaw position, temporomandibular joints, and masticatory muscles, achieved functional coordination. Conclusions:The application of digital workflow enables accurate impression production for fixed dental restorations, replicates the dynamic jaw position relationship of temporary restorations, and dynamically adjusts the bite of formal restorations. This approach optimizes the occlusal adaptability of the restoration and reduces clinical adjustment time.
