“…No significant difference was noted in maximum occlusal force between occlusal schemes detectable with the dental prescale. Although other studies that used subjective methods to evaluate chewing ability between different occlusal schemes reported inconsistent results, [23][24][25][26]28 in this study, the patients' preferences for an occlusal scheme could not be related to masticatory performance when measured objectively. The present study evaluated the masticatory performance and maximum occlusal force objectively.…”

A few intra-individual studies with the same denture base have also been performed.…”

CRP--Studies of occlusal form and tooth arrangements, included balanced, lingualised and monoplane arrangements--lingualised posterior occlusion was preferred. Early studies on CRP design were observational as case reports, however data suggested that optimum function is achieved by modification of the maxillary occlusion, irrespective of the opposing mandibular occlusion. PRP--Edentulous ridge resorption is patient-specific, has a multifactorial aetiology and there is no objective data to confirm that mechanical factors cause bone loss; oral hygiene management is crucial for long-term health. Studies on distal extension PDs confirmed a link between bite force and masticatory function; preservation of two functioning posterior tooth units ipsilateral to the distal extension optimises function. Data indicate that patient-specific factors, rather than PD design-specific features, influence long-term PD outcomes. Implant superstructures--There is little scientific evidence specifying occlusal and superstructure design for fixed prostheses for teeth or implants. Occlusal scheme design and occlusal form have evolved through clinical experience, but there is no evidence to indicate that a particular design is superior. Complex neurophysiological mechanisms allow the jaw muscle system to accommodate to oral and dental changes.

“…In contrast, nonanatomic ones do not have a straight occlusal plane with cusp inclination at 0°. 9 Sutton et al 6 and Shetty 10 reported that nonanatomic teeth reduce lateral stress, minimize the masticatory load, and allow freer lateral movement without treatment, thus promoting better prosthesis stability, which would imply smaller TMJ effort. This study aims to report a case of an association between surgical treatment of temporomandibular dysfunction and total prosthesis (TP) rehabilitation using nonanatomic teeth in patients with recurrent anterior dislocation of the TMJ and persistent involuntary mandibular movement.…”

Aim:To report a case of association between the surgical treatment of temporomandibular dysfunction and rehabilitation with denture total prosthesis (TP) using nonanatomic teeth (cusp 0°) in patients with anterior recurrent dislocation of the temporomandibular joint (TMJ) and persistent uncontrolled mandibular movement, showing a technical adaptation and conduct.Introduction: There are several treatment approaches available for dislocation of the TMJ. The use of condylar mini-anchors for recurrent TMJ dislocation is a valid option and should be considered since it does not alter the joint anatomy. In edentulous patients undergoing TMJ surgical procedures, prosthetic rehabilitation can be seen as a means of treatment preservation. Case report:A 73-year-old female patient attended the oral and maxillofacial surgery clinic presenting with joint instability, ligament laxity, and chronic recurrent TMJ dislocations. She had already been through three previous unsuccessful surgical procedures. A treatment plan was done based on the installation of a mini-anchor in the patient's TMJ through the preauricular surgical access. Dislocations were then resolved, but the lack of mandibular control even to a lesser extent after surgery precluded the use of prosthetics even at rest. Conclusion:The use of an individual mini-anchor is simple and effective, and the use of artificial teeth is well suited to the case.Clinical significance: A multidisciplinary intervention (surgery/ prosthesis) is of utmost importance for the resolution and preservation of the treatment of these complex cases.
