The objective of the present article is to demonstrate the digital workflow used to manufacture an adjusted oral splint in a patient case.
A 25-year-old female patient presented for management of her bruxism. Therefore, an adjusted oral splint was manufactured. A computer-aided motion analysis of the patient was conducted (JMA Optic). Full-arch scans of the maxilla and mandible, a biocopy of the maxilla with a bite fork, and buccal scans of the centric jaw relation (Primescan) were performed. The jaw relation was determined beforehand by ballistic closing on a chairside-fabricated anterior jig. The digital construction of a Michigan splint took place in the dental laboratory. The design was nested and milled from a polymethyl methacrylate (PMMA)-containing blank (CLEARsplint Disc).
The oral splint was inserted into the patient's mouth and checked to ensure a tension-free fit. The static and dynamic contact relationship was checked. During the follow-up visit, the patient reported an improvement in tension in the masticatory muscles.
The described procedure allows for the manufacture of an adjusted oral splint through a purely digital workflow.
本文旨在展示用于制造患者调整式口腔夹板的数字化工作流程。
一位 25 岁的女性患者因磨牙症前来就诊。因此,我们制造了一个调整式口腔夹板。对患者进行了计算机辅助运动分析(JMA Optic)。对上颌和下颌进行全口扫描、使用咬叉进行上颌生物复制、以及进行正中颌位颊侧扫描(Primescan)。颌位关系通过在椅旁制作的前夹具进行弹丸关闭来预先确定。在牙科实验室进行密歇根夹板的数字化构建。设计嵌套并从含有聚甲基丙烯酸甲酯(PMMA)的毛坯(CLEARsplint Disc)中铣削而成。
将口腔夹板插入患者口中,并检查以确保无张力贴合。检查静态和动态接触关系。在随访就诊时,患者报告咀嚼肌张力有所改善。
所描述的程序允许通过纯数字化工作流程制造调整式口腔夹板。
