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.

The treatment of bruxism is reduced to several main methods - increasing the vertical dimension of occlusion (VDO) to normal, medialization of the mandible to influence the position of the joint condyle in the joint fossa and release the disc, and positioning the mandible in a balanced stable occlusion.[2,3]

Summary
Bruxism is a disease with a multifactorial etiology, such as stress, occlusal factors and trauma. We report a patient with bruxism, where proper articulation of the occlusal splint was performed using the T-scan Novus System. 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). On the last recording of the occlusion, evenly distributed contacts in the area of the lateral teeth were established The forces on both sides are approximately equal (right side 50.3%, left side 49.7%) and COF was in the middle. The frontal area was marked with contacts with the articulation paper and foil, which weren’t registered by the T-Scan Novus System (Figure 11)
