Abstract

Aim: The objective of the present article is to demonstrate the digital workflow used to manufacture an adjusted oral splint in a patient case.

Materials and methods: 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).

Results: 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.

Conclusion: The described procedure allows for the manufacture of an adjusted oral splint through a purely digital workflow.

口腔夹板制造的数字化工作流程。

目的：将在一个病例中演示用于制作调整型口腔夹板的数字化工作流程：一名 25 岁的女性患者前来治疗磨牙症。因此，制作了一个调整型口腔夹板。对患者进行了计算机辅助运动分析（JMA Optic, Amann Girrbach），并对上颌骨和下颌骨进行了全颌面扫描，还对上颌骨和咬合叉进行了生物扫描，并对下颌中心关系进行了颊面扫描（Primescan, Dentsply Sirona）。下颌关系是事先通过在椅旁制作的前牙夹具上进行弹道闭合确定的。密歇根夹板的数字化制作在实验室进行。设计是根据含有聚甲基丙烯酸甲酯（PMMA）的坯料（CLEARsplint Disc，Astron Dental Corporation）进行嵌套和研磨的：结果：将口腔夹板放入患者口中并进行检查，以确保无张力配合。检查了静态和动态接触关系。随访期间，患者表示咀嚼肌的张力有所改善：结论：所述程序允许在纯数字化工作流程中制造调整后的口腔夹板。

期刊介绍： This journal explores the myriad innovations in the emerging field of computerized dentistry and how to integrate them into clinical practice. The bulk of the journal is devoted to the science of computer-assisted dentistry, with research articles and clinical reports on all aspects of computer-based diagnostic and therapeutic applications, with special emphasis placed on CAD/CAM and image-processing systems. Articles also address the use of computer-based communication to support patient care, assess the quality of care, and enhance clinical decision making. The journal is presented in a bilingual format, with each issue offering three types of articles: science-based, application-based, and national society reports.
