Clinical outcomes of different centric relation recording techniques in edentulous individuals: An observational cross-sectional study

Abstract

Background: For the rehabilitation of edentulous patients, the centric relation (CR), which is regarded as a repeatable and useable reference position, is the best maxillomandibular position. Objective: We sought to evaluate the reproducibility of interocclusal wax and extra oral Gothic arch techniques for centric relation (CR) recording, as well as subjective evaluation of dentures made in this way for edentulous people. Methods: In 18 patients with total denudation, centric relation and horizontal condylar guidance were detected utilising interocclusal wax and Gothic arch tracing. The articulator received these records, and the difference between the two values was noted. Following that, patients were split into two groups based on how the horizontal condylar guidance recording method and centric relation were used to create balanced occlusion. "Woelfel subjective evaluation criteria" were used to evaluate the dentures' response subjectively. Each technique's ability to be repeated was evaluated. Results: In 22.41% of patients, the CR obtained using the static method (interocclusal wax record) was posterior to the CR obtained using the functional method (Gothic arch tracing), whereas in 70.92% of patients, the CR obtained using the static method was anterior to the CR obtained using the functional method, with the difference in CR varying between 0.5 and 1 mm. The clinical effectiveness of the entire denture is unaffected. According to subjective opinion, none of the measures in either group were statistically significant. By both techniques, the horizontal condylar guiding angle was roughly similar. Conclusion: The dentures made using the two distinct approaches were comparable in terms of correctness of centric relation, retention and stability, condition of basal tissues as well as chewing effectiveness and level of patient satisfaction.
