Qualitative Evaluation of 3D Resin and Acrylic Occlusal Splints in the Treatment of Temporomandibular Disorders: A Pilot Study

Abstract Introduction: This study addresses the increasing application of digital technologies in dentistry, specifically in the fabrication of occlusal splints for the treatment of temporomandibular disorders (TMD). It investigates the effectiveness, fit, and comfort of splints made using conventional and digital methods (3D resin and acrylic), considering the importance of precision in TMD treatment. Methodology: The research was conducted with a sample of ten patients, evaluating the splints in terms of retention, adaptability, tilting, and the need for reprinting. Conventional and digital splints were compared using qualitative measurements and patient satisfaction as indicators. Results: Conventional splints demonstrated solid performance across all evaluated categories. However, a digital splint initially presented fitting problems, requiring reprinting. Despite this, digital splints showed significant advantages in precision and efficiency after necessary modifications, with high patient acceptance. Conclusions: The research highlights the potential of digital techniques in the fabrication of occlusal splints, suggesting superiority in terms of adaptability and patient satisfaction, despite initial fitting challenges. This study underscores the importance of technological innovation in improving dental care for TMD patients, recommending greater adoption of digital methods in clinical practice.
