Abstract

Understanding the applicability, importance and effectiveness of Gysi's Gothic arch for carrying out oral rehabilitation treatment with complete dentures helps professionals to make the most appropriate diagnosis and treatment choice, reduces the need for adjustments during prosthesis adaptation and minimizes possible errors during patient assessment and procedure planning, in addition to being able to be used together with techniques that aim to define centric relationship and maximum centric intercuspation, and with measurements of the vertical dimension of occlusion and the vertical dimension at rest to complement the data offered by the Gysi tracing. This work aims to discuss the effectiveness and applicability of Gysi's gothic arch as a method for obtaining the central relationship for edentulous patients. A qualitative exploratory and descriptive research was carried out through a narrative literature review, using the Google Scholar, SciELO, LILACS and BVS databases and the descriptors “Total Prosthesis”, “Central Relation” and “Dental Occlusion”. According to the literature, the outline of the Gothic Arch of Gysi was the only scientific method to record the CR, regardless of whether it was used in intraoral or extraoral recording. Gysi's Gothic Arch is timeless in obtaining mandibular movements. It has reliability in obtaining the extension and each mandibular movement, as well as the condylar trajectory. Balancing the bite, the TMJ and the muscles of the stomatognathic system. Therefore, since there is no totally effective method for obtaining the CR, the gothic arch remains an important alternative with high applicability for the dental surgeon in the manufacture of complete dentures.
