Abstract
Bruxism is a disease with a multifactorial etiology. Its clinical manifestations are most often an unaesthetic smile with abraded tooth surfaces, temporomandibular disorders and muscle hyperactivity. Here we present a case of bruxism where proper articulation of the occlusal splint was performed using the T-scan Novus system. A patient with bruxism underwent treatment with stabilization splint made by 3D printer technology. Intraoral scanning was performed using Trios Color (3Shape, 2014), and the digital design was achieved using the 3Shape Dental system design - splint studio. Formlabs Form 2 printer with biocompatible resin Dental LT Clear Resin was used for printing. The T-Scan Novus system with software attached to it, version 9.1, was used for digital examination of the occlusion. A 2.7 mm thick occlusal splint was developed, and the software adapted the occlusion with antagonists. After adjustment with T-Scan Novus, a reduction in disocclusion time of the patient was achieved, which is a desired result in the treatment of bruxism. The position of the joint components was proven radiologically. The treatment of bruxism with splint therapy continues to be the main method of treatment. Using digital technology allows for more accurate constructions and precise balancing of occlusal relationships.
Highlights
Bruxism is a disease with a multifactorial etiology
The following changes have been made to the improved version of the article: 1. It was added a description of the intraoral scanner - Trios Color (3Shape, 2014)
Two articles showing the high precision of the used scanner were added - 3Shape intraoral scanners demonstrate a very precise virtual model, especially in distal zones.[8,9 3]
Summary
Any reports and responses or comments on the article can be found at the end of the article. We report a patient with bruxism, where proper articulation of the occlusal splint was performed using the T-scan Novus System. Initial digital design of the splint The digital software allows different design options In this case, the following parameters of the lower jaw position were set: vestibular thickness of the splint at 1 mm; occlusal opening at 2.7 mm; and protrusion at 1 mm (Figure 3). Occlusal surfaces were softwareextended and provide wider contact This is especially evident in the anterior teeth area. As the patient's clinical crowns were without retention areas, the splint borders were located to the cervical zone vestibularly and palatally, except the distal teeth, where the borders were 1 mm up of the cervix vestibularly This extension contributed to its stable position (Figures 4 and 5).
