摘要/Abstract

摘要： 目的介绍一种步骤明确、技术评价指标清晰的咬合重建方法。方法选择无颞颌关节-咀嚼肌疼痛不适、承受咀嚼压力无痛、重度磨耗的恒牙列病例,在正中关系铰链运动的轨迹上,以满足修复空间需求的最小距离来确定垂直距离,从而构建牙尖交错牙合。以微笑分析原则进行前牙美学设计和“简单治疗牙合“原则设计咬合接触关系。结果对10例固定修复咬合重建患者观察1~5年,患者对美学、功能恢复满意;咬合稳定无干扰;无关节区、咀嚼肌的疼痛不适,口颌系统健康舒适。结论本研究提供了一种可以实现颞颌关节-咀嚼肌-咬合关系协调舒适的咬合重建技术体系。

Abstract: Objective To develop a protocol of fixed occlusal rehabilitation for severely worn permanent dentition. Methods Severely worn permanent dentition with no sign of tension/pain of temporomandibular joint and muscles when loading was included. On the pathway of hinge movement at centric relation position, the minimal thickness required by restoration materials was used to determine the vertical dimension of occlusion and construct intercuspal occulusion. The occlusion contact was designed by the principle of aesthetic prosthodontics and the simplified therapeutic occlusion. Results Ten patients with fixed prosthesis followed up for 1 to 5 years were satisfied with its aesthetics and function. The occlusion was stable with no occlusal interference. There were no signs of tension/pain of temporomandibular joint and muscles. The stomatognathic system was healthy and comfortable. Conclusion The easy-controlled protocol of full-dentition rehabilitation may achieve the coordination in stomatognathic system.
