Aim: The digital workflow used to manufacture an adjusted oral splint will be demonstrated 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, Amann Girrbach) and full-arch scans of the maxilla and mandible, a biocopy of the maxilla with bite fork as well as buccal scans of the centric jaw relation (Primescan, Dentsply Sirona). 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 laboratory. The design was nested and milled from a polymethyl methacrylate (PMMA)-containing blank (CLEARsplint Disc, Astron Dental Corporation).Result: The oral splint was inserted into the patient’s mouth and checked to ensure a tensionfree 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 procedure described allows for an adjusted oral splint to be manufactured in a purely digital workflow.
