Comparison of condylar displacement between three biotypological facial groups by using mounted models and a mandibular position indicator

Abstract: ObjectiveFacial-type-associated variations in diagnostic features have several implications in orthodontics. For example, in hyperdivergent craniofacial types, growth imbalances are compensated by displacement of the condyle. When diagnosis and treatment planning involves centric relation (CR), detailed knowledge of the condylar position is desirable. The present study aimed to measure condylar displacement (CD) between CR and maximum intercuspation in three facial types of an asymptomatic orthodontic populati… Show more

“…Similarly, Ponces et al . [ 21 ] analyzed 216 condyles and found almost identical results to the present study, with a CD ≥ 2 mm in 27.77% of the cases in the vertical plane and a CD ≥ 2 mm or CD ≤ 2 mm in 6.49% in the horizontal plane. Nevertheless, other studies [ 33 ] have found conflicting results, suggesting that some factors related to the influence of the skeletal pattern on CR-MIC discrepancies remain unexplained.…”

“…Following the recommendations made by Joao Ponces et al . [ 21 ], the same operator carried out the CR registration, cast mounting procedures, and MCD measurements over two sessions within a 10-d period in order to evaluate intra-operator error and test the reproducibility of CR registration. For these procedures, eight patients were randomly selected and the clinical measurements were obtained twice during each session.…”

“…31 Moreover, most patients show a centric relation-centric occlusion discrepancy, usually caused by a posterior interference that is unilateral in most cases. [40][41][42][43] As an adaptation, the condyles might move asymmetrically and while the contra-lateral condyle moves sagittaly, the ipsilateral rotates to establish a more balanced dental occlusion. The absence of statistically significant differences between right and left joints for the PJS may be explained by stabilization of the TMJ posteriorly by the articular disk.…”

“…32,33 As a response to occlusal fulcrums, the neuromuscular system will displace the condyle more inferiorly to achieve maximal occlusal contact. 34 The condyle was displaced to a more inferior position within the fossa as a consequence of the adoption of orthodontic treatment. Although the statistic results showed that condyle move downward significantly, this fact may not influence TMJ clinical signs.…”
