Virtual Articulator: Integration of Functional Occlusion in Digital Workflows for Oral Rehabilitation

This article explores the use of the virtual articulator within the Exocad software, emphasizing its significance in digital dentistry, particularly in oral rehabilitation. Although still underutilized by many professionals primarily due to a lack of knowledge regarding its theoretical foundations the virtual articulator is a key tool for precise prosthetic planning based on classical principles such as Bonwill’s equilateral triangle and the studies of Rudolf Slavicek. Clinical experiences have demonstrated that proper application of these principles enhances clinical predictability, minimizes intraoral adjustments, and improves patient comfort. The workflow involves model digitization using either individualized parameters provided by the clinician or standardized values widely validated in the literature. Manual adjustments within the Exocad virtual articulator can be tailored to the patient's anatomical and functional characteristics, enabling a more personalized approach. Results indicate superior outcomes with the digital workflow when the virtual articulator is employed, especially in zirconia-based prosthetic structures, supporting safer, more predictable, and efficient oral rehabilitations.
