[A complete denture rebasing method in two appointments].

During rebase of the complete dentures, the denture bases are used as the trays for making border molding and final impression. Both open--mouth and closed-mouth impression methods are certainly expected to change the relationship between acrylic teeth and denture base after impression procedures. The upper denture usually shifts forward and downward, as a result, the occlusal relationship and esthetics are both damaged. The purpose of this article was to introduce an effective method for rebasing complete dentures. Through utilizing (1) the interridge distance, (2) the distance between the upper edentulous ridge and the occlusal surface of the lower acrylic teeth, and (3) the interocclusal records obtained immediately after each impression, the displacement of denture base can be corrected accurately. In addition, the original occlusion and esthetics are able to be preserved.

[Use of the maximal physiologic load test in the evaluation of functional values of newly made complete dentures and dentures rebased by the Rehm method].

There is a constant dilemma of dental practitioners in contact with patients in whom complete dentures have lost congruent relation toward supporting mucoosseous tegmen if new dentures should be made or rebased by change of denture base. The investigators who have studied those problems have been mostly concerned with problem of material and rebasing procedures of complete dentures. The aim of the study was to determine the functional value of unrebased, rebased by Rehm and new complete dentures and compare the time of initial functional adaptation of patients to rebased and new complete dentures. The study included 72 examinees. The functional value of complete dentures was estimated by test of masticatory muscles, bioelectrical activity by test of masticatory efficacy and by test of maximal physiological load. On the basis of the study it was concluded that complete dentures rebased by Rehm were in function worthier than unrebased, and the period of initial functional adaptation was missing. In the examinees with pair of newly made complete dentures, functional tests revealed the reduction of initial values after the new dentures were delivered. During the examination interval, progressive dynamics with tendency of establishing the optimal functional value and initial functional adaptation was revealed after 21 days.

Flexural strength of rebased denture polymers.

The properties of denture base and reline resins may be affected by daily changes between room temperature and mouth temperature. The purpose of the study was to evaluate the effect of thermocycling on the flexural strength of the relined denture base polymer with reline resin. Three denture base resins, three hard reline resins and their combinations were tested. Fourteen specimens, 65x10x2.5 mm, were fabricated for each material. Polymer combination specimens were made using 1.5 mm hard reline resin on 1.0 mm cured denture base resins. Half of the specimens were stored for 50+/-2 h in distilled water at 37 degrees C, while the other half were thermocycled for 20 000 cycles between 4 and 60 degrees C. Three point bending tests were conducted on a universal testing machine at a cross-head speed of 0.5 cm/s. The flexural strengths were measured and a statistical analysis was performed on the data using three-way ANOVA (P<0.05). The results showed that the flexural strength of relined denture base polymer was significantly higher than that of hard reline polymer. Thermocycling did not affect the flexural strength of the relined denture base polymers, whereas the denture base polymer and reline polymer alone showed a decrease in strength after thermocycling.
