“…In small and moderately powered studies (n = 80/58/26), those patients diagnosed with mandibular prognathism treated with vertical ramus osteotomies possessed a significant increase in occlusal force that likewise increased occlusal contact. [64][65][66] However, a systematic review of 697 patients treated for class III or mandibular prognathism revealed that the occlusal force was less two years after the vertical ramus osteotomy or sagittal split osteotomy. 67 Other cross-sectional studies (n = 78) that examined occlusal force traits indicate those subjects with apertognathia and Class II malocclusion or a posteriorly rotated mandible tend to have reduced occlusal force compared to those with Class I occlusion and less steep mandibular planes and reduced facial height.…”

“…Orthognathic classification is another variable that has a differential occlusal force potential often measured as a surrogate treatment outcome from orthognathic surgery. In small and moderately powered studies (n = 80/58/26), those patients diagnosed with mandibular prognathism treated with vertical ramus osteotomies possessed a significant increase in occlusal force that likewise increased occlusal contact 64–66 .

Purpose: The purpose of this Best Evidence Consensus Statement was to search the literature to determine if there is a relationship between patient specific factors and occlusal force. Materials and Methods: A literature review was conducted in the following databases: Evidence-Based Medicine Reviews (EBMR), Cochrane Database of Systematic Reviews, Embase, and Ovid MEDLINE(R) and Epub Ahead of Print. Articles on patient factors and occlusal force were compiled by using a combination of the key words: "bite force," "occlusal force," "partial and complete edentulism," "bruxism," and "orthognathic class." Inclusion criteria included meta-analyses, systematic reviews, randomized controlled trials, case series, and journal articles. Exclusion criteria were case reports, studies in children, animals, and bench studies. Results: Of the 1502 articles that met the initial search criteria, 97 related to patientspecific factors affecting occlusal forces. These articles were evaluated, rated, and organized into appropriate categories addressing questions of foci. Conclusions: The range of occlusal force is highly variable among subjects correlated to patient specific factors such as age, gender, partial and complete edentulism, the presence of a maxillofacial defect, location of edentulous area, orthognathic profile, and magnitude of occlusal vertical dimension. Tooth replacement therapies targeted at increasing occlusal contact seem to have a positive effect on increasing occlusal force. Bruxism does not necessarily demonstrate higher occlusal powering but may have greater tooth contact time. Occlusal force is not clearly affected by the type of dental restoration or restorative material used. The clinical significance of the changes in occlusal forces is yet to be determined.

“…Several factors are known to affect masticatory efficiency, for example, the occlusal contact area,789 bite force,9101112 malocclusion,813141516 number of functional teeth,11 oral motor function,17 and temporomandibular dysfunction 8. Henrikson et al8 and English et al14 have reported that malocclusion negatively affects masticatory efficiency.…”

ObjectiveThe objective of this study was to investigate the differences in masticatory efficiency among patients with different Angle's classes of malocclusion and to assess the correlation between masticatory efficiency and the occlusal contact area.MethodsThe mixing ability index (MAI) was calculated for measuring masticatory efficiency of 61 adult patients according to Angle's classifications of malocclusion. The study included 25, 15, and 21 patients with Angle's Class I, II, and III malocclusions, respectively. Silicone interocclusal recording material was used to measure the occlusal contact area.ResultsBoth the MAI and occlusal contact area showed the highest average values in the Class I malocclusion group, followed by the Class II and Class III malocclusion groups. No significant difference was observed in the MAI values between the Class I and Class II malocclusion groups (p > 0.05), whereas a significant difference was observed between the Class I and Class III malocclusion groups (p < 0.01) and between the Class II and Class III malocclusion groups (p < 0.05). A weak positive correlation was also observed between the MAI and occlusal contact area (p < 0.01, r2 = 0.13).ConclusionsThe results of this study indicated that masticatory efficiency was the highest in patients with Angle's Class I malocclusion, followed by those with Angle's Class II and Angle's Class III malocclusions. Moreover, a weak positive correlation was observed between masticatory efficiency and the occlusal contact area.
