“…2,[7][8][9]14,15 The present study has included completely edentulous patients master casts on which teeth were setup. While models with standard molds have a uniform thickness of flanges in all samples and the same OVD, which are advantageous in most studies, master casts of the patients (as used in the present study) inevitably have no uniform thickness in terms of the dimensions of flanges and different OVD which may have an impact on the changes of the OVDs and the number of occlusal contacts.…”

“…[1][2][3][4][5] The stability of a complete denture is highly dependent on an even distribution of the occlusal load, which can be achieved by obtaining the maximum intercuspation in the centric relation and by elimination of occlusal errors. [6][7][8][9] This intercuspation should be established bilaterally on the posterior artificial teeth. Unilateral and insufficient occlusal contacts, which are defined as an incorrect occlusion, and the consequent trauma affect the retention and resistance; cause soft tissue soreness, accelerate residual ridge resorption; and decrease masticatory efficiency.…”

“…20,21 Several studies have discussed the effect of molding and processing methods on the OVD of the complete dentures. [2][3][4][5][6][7][8] However, the effect of the applied method on the number and distribution of the occlusal contacts has not been investigated in great detail. 3 Moreover, these studies have mostly been done on low numbers of simulated edentulous jaws or models.…”

Aim: Occlusal errors during acryl processing affect the retention and stability of complete dentures. The aim of the present study was to assess the influence of a short curing technique on the number of occlusal contacts and the occlusal vertical dimension (OVD) of complete dentures. Materials and methods:Complete dentures were prepared. The number of occlusal contacts was recorded in centric relation (CR) using 60 µ articulation paper. The OVD was recorded with the waxed trial denture in place. Dentures were then invested and processed with compression molding and short cure water bath technique. The number of occlusal contacts was recorded again. The amount of pin opening was measured for all of the complete dentures on the articulator. Data were analyzed with paired t-test to determine the alterations. Results:The mean number of occlusal contacts before and after processing was 10.9 ± 2.4 and 6.3 ± 3.1 respectively (4.7 ± 1.9 decrease; p < 0.001). A 2 mm mean increase in OVD was observed in 47.7% of the dentures with < 6 occlusal contact changes and 88.9% of the dentures with ≥ 6 occlusal contact changes (p < 0.003). A significant change in the number of occlusal contacts was associated with an OVD increased up to two times. Conclusion:The short curing technique seems to be related to the decreased occlusal contacts and increased OVD. Clinical significances:More time is needed to adjust the occlusal errors of this method, because it has a negative effect on the morphologic pattern of artificial teeth of complete dentures and thus should be used carefully.
