“…OCAs or occlusal points have been compared using occlusal articulating paper (1,2), occlusal strips or silk (3,4), alginate impressions (5-7), black silicone bite registration material (8), pressure-sensitive film (9,10), the T-Scan system (11,12), and silicone material. These studies demonstrated a positive correlation between OCAs or occlusal points and tooth clenching intensity.…”

The aim of this study was to investigate the occlusal contact area (OCA) in individual teeth during low-level tooth clenching in 24 healthy participants. Before measurements were made, the 100% maximum voluntary contraction (MVC) was determined. At baseline, all subjects were instructed to close their mouth and touch the opposing teeth with minimal force. Occlusal contact was recorded during three jaw motor tasks (baseline, 20% MVC, and 40% MVC) using a blue silicone material. OCA thickness was determined from images and defined on five levels: level 1 (0-149 µm), level 2 (0-89 µm), level 3 (0-49 µm), level 4 (0-29 µm), and level 5 (0-4 µm). Premolar and molar OCAs increased significantly from baseline to 20% MVC and 40% MVC. The OCA of each anterior tooth did not change significantly with increasing clenching intensity at all levels. Our findings suggest that premolar and molar OCAs may be altered by low-intensity clenching, affecting the teeth and periodontal tissues.

“…Studies on the reproducibility of facebow transfers have shown variations in methodology and results. [5][6][7][8][9][10][11][12][13][14] The literature supports the notion that an accurate transfer of the orientation of the OP can significantly affect function 15,16 and esthetics. 17,20 A study by Kattadiyil et al 20 reported that perceived changes in OP orientation affected the esthetic preference for smiles.…”

“…The accurate transfer of the orientation of the OP can significantly affect function 15,16 and esthetics [17][18][19][20] has implications in the field of orthognathic surgery. 11 The effect of the OP on esthetics was discussed by Pitchford, 17 who stated that failure to transfer the OP accurately can result in complete dentures with an OP in which the maxillary posterior teeth seem to hang below the anterior teeth.…”

“…On the contrary, the closing angle near the intercuspal range was found to be related to occlusal guidance. 25 This may explain why closing angle was similar in the two chewing tests.…”

In application of the mixing ability test for evaluating objective masticatory function, clinicians should recognize that the mixing ability test is partially different from a traditional masticatory performance test in respect of masticatory movements. AbstractPurpose: The purpose of this study was to compare mandibular movements in the mixing ability test with those in the masticatory performance test.Methods: Twenty-six dentate subjects (mean age 25.3 years) performed a mixing ability test using a twocolored paraffin wax cube and a masticatory performance test using 3 g peanuts. Mandibular movements during the chewing of each test item were recorded using an opto-electronic system. Twelve parameters of mandibular movements on a mandibular incisal point were measured for each masticatory cycle. The mean from 2 nd to 5 th cycle in each parameter was employed for paired t-test. Results: 7 of 12 parameters showed significant mean differences between the mixing ability test and the masticatory performance test. Vertical amplitude, anteroposterior amplitude, maximum closing velocity and opening angle for the mixing ability test were significantly greater than for the masticatory performance test (P<0.05). Opening duration and cycle duration for the mixing ability test were significantly longer than for the masticatory performance test (P<0.05). Envelope angle for the mixing ability test was significantly less than for the masticatory performance test (P<0.001). Conclusion:The results of this study suggest mandibular movements in the mixing ability test are partially different from those in masticatory performance test.
