Centric relation and the treatment position in rehabilitating occlusions: A physiologic approach. Part II: The treatment position

Cone-beam tomography assessment of condylar position discrepancy between centric relation and maximal intercuspation

“…[3][4][5] Many authors support the use of CR in occlusal rehabilitation therapy, 3,11 since they consider it an easily reproducible reference position, and also in orthodontics, 1,3 strongly advocating the need to plan any treatment by mounting study models on an articulator and performing diagnostic teleradiography, both using CR.…”

“…[3][4][5] Some authors, however, have reported more balanced views, admitting that both RC and MI may be used in oral rehabilitation according to each patient's specific situation. According to this view, extensive prosthetic restorations, occlusal adjustments, parafunction management, rehabilitation after orthognathic surgery, unsatisfactory MI, TMD management, and orthodontic therapy of greater complexity would be indications for using CR.…”

“…In contrast, less extensive oral rehabilitations, a stable MI position, the absence of signs and symptoms, and less complex orthodontic therapy would be indications for using MI. [3][4][5] Based on the results of the present study, the latter approach seems to be a more logical choice. Despite the limitations previously discussed, the absence of symptoms and the relative similarity of results in our study sample suggest the existence of a relative balance capable of preventing pathologic changes in the condyle/fossa relationship, a balance which could be maintained after low-complexity procedures.…”

“…[1][2][3] Opinions diverge greatly with regard to the clinical use of these maxillomandibular positions. Systematic literature reviews include authors in favor of an extensive use of CR in the planning of occlusal rehabilitation therapy and orthodontics, 1,3 alongside others who suggest an individual analysis of each clinical situation when determining which maxillomandibular relationship should be considered correct.…”
