Adaptation of acrylic resin dentures as influenced by the activation mode of polymerization.

With the advent of newer methods of activation of the polymerization of denture base resins, there is a need to compare dentures constructed using various modes of activation such as heat, light, and microwave energy. This study compares the dimensional accuracy of a conventional heat-activated acrylic resin poly (methyl methacrylate) with a new pour resin, a visible light-activated resin, and microwave-activated acrylic resin, all polymerized for denture bases. All groups showed a processing contraction; the poorest-fitting group was processed in a brass flask and a water bath at 70-100 C, using a heat-activated resin (Acron); the relatively new light-activated resin (Triad) produced dentures of intermediate accuracy, as did Acupac 20, when either heat- or microwave-activated. The two best-fitting groups were prepared from an autopolymerizing resin (PERform) and the microwave-activated resin (Acron MC).

Suction cups on maxillary dentures: report of case.

A report of case is presented in which a maxillary denture was fitted with a suction cup causing a round, depressed area of inflammation on the center of the palate. Awareness of existing prosthodontic practices is important to recognize and manage such a case for the restoration of tissue health and prevention of further tissue damage.

A clinical study of rest position using the Kinesiograph and Myomonitor.

The clinical study was designed to study the vertical dimension of rest position and mandibular closure to maximum intercuspation of the teeth before, during, and after relaxation procedures on 14 subjects with stable dentitions. The findings call attention to the potential of both the Myomonitor and the Kinesiograph for research and clinical use, to the physiologic need for flexibility of the vertical dimension of rest position, and to the importance of measuring all three dimensions when examining the rest position.

The effect of relining on the accuracy and stability of maxillary complete dentures--an in vitro and in vivo study.

A technique was developed for evaluating in vitro the accuracy or fit of experimental denture bases using a low-viscosity impression material for determining the space between the master die and the processed denture base. These measurements indicated that relining heat-cured maxillary denture bases with autopolymerizing acrylic resin improved their adaptation to the ridges. Interestingly, if no teeth were present in the heat-cured denture base, markedly less distortion occurred after processing. Limited clinical measurements on the stability of maxillary dentures in function showed no statistically significant change in stability after relining, but the trend was toward increased stability with the relined denture.

Pulp reaction to a tricalcium phosphate ceramic capping agent.

A porous form of tricalcium phosphate ceramic has been shown to stimulate new bone formation around the implant. The purpose of the present study was to evaluate this material in a powder form as a pulp-capping material. It was found difficult to cover a pulp exposure adequately with Synthos ceramic powder alone. Histologic sections showed dentinogenesis around those particles which were forced into the pulp proper, demonstrating the nonirritating potential of Synthos. Because of the bacterial infection in so many of the specimens, this study is inconclusive with respect to the use of this material as a capping agent. A similar study, employing a rubber dam to protect the exposure, is recommended.

Effect of autogenous marrow and calcitonin on reactions to a ceramic.

The effect of autogenous marrow and calcitonin on reactions to a tricalcium phosphate ceramic was studied by subcutaneous implantation in rats. No bone formation was evident in association with uncoated and calcitonin-coated ceramic. At four weeks and thereafter bone formation was evident in association with all marrow-coated implants.
