Comparisons of tactile thresholds between implant-supported fixed partial dentures and removable partial dentures.

This study compared the tactile sensitivity of splinted abutment and denture teeth of 16 fixed partial dentures (FPD) supported by blade implants and 16 removable partial dentures (RPD) in patients with Kennedy Class I and Class II edentulous conditions. No significant differences were noted between the tactile thresholds of the natural abutment teeth and artificial teeth in the FPD and RPD groups. The splinted abutment teeth required 45.4 g, or 5.4 to 5.8 times higher occlusal loads than did those needed for the comparable nonsplinted teeth, to detect the stimulus. A further increase of 54% in thresholds with the FPD and over 100% with the placement of the RPD indicated the superiority of the RPD in terms of load distribution as a result of the cross-arch splinting and mucosal support. Moderate positive correlations (r = 0.37 to 0.46; P < .05) between tactile thresholds and masticatory performance were found, signifying that reduced tactile perception was not responsible for the incomplete restoration of the masticatory function with RPDs or FPDs but might be contributing to increased masticatory performance within both treatment groups.

The prevalence of Candida albicans in complete denture and removable partial denture wearers: a comparative study.

In this study, 60 complete denture wearers, 53 removable partial denture wearers and 50 dentate subjects were examined to determine the Candidal carrier state. The influence of local factors such as denture type, smoking habits and sex on Candidal carrier rate were investigated. Wearing complete or removable partial denture was determined as an important factor increasing Candidal carrier rate. Cigarette smoking is another factor which increases Candidal growth in complete denture and removable partial denture wearers. In contrast to denture wearers Candidal carrier rate was considerably less on dentate smokers. Candidal colonization rate was found to be higher on the dorsum of the tongue. This suggests that the tongue is the primary oral reservoir of Candida albicans in the mouth.

Subjective reactions to major connector designs for removable partial dentures.

Simlated partial denture frameworks were fabricated for 12 dentists (subjects) who had intact dentitions and who had intact dentitions and who had had no previous experience in wearing partial dentures. The outline of the major connectors was modified during a 1 week interval. The data obtained from questionnaires brought about the following conclusions: 1. Preferences in maxillary major connector design were as follows: (1) broad posterior strap, (2) anteroposterior bar, (3) ring-type design, and (4) full palatal coverage. 2. The mandibular lingual bar was chosen over the lingual plate by a 3:1 ratio. 3. The natural palatal metal finish was perferred to the highly polished finish. 4. Metal borders parallel to tongue movement were better tolerated than those lying transverse. 5. Thickening of the posterior strap to permit its narrowing was not clinically feasible. 6. In general, patients adapted best to major connectors that covered the least amount of soft tissues.

Interim complete immediate dentures for a patient wearing removable partial dentures.

This article describes a technique used for fabricating temporary (interim) complete dentures for a patient who had been wearing removable partial dentures and whose remaining teeth were to be extracted. Rather than attempt to incorporate the existing removable partial dentures into the interim complete dentures, the dentist used the existing dentures to fabricate acrylic resin teeth for the interim prosthesis.

The influence of heat treatments on several types of base-metal removable partial denture alloys.

Four removable partial denture alloys, Vitallium (Co-Cr alloy), Dentillium P.D. (Fe-Cr alloy), Durallium L.G. (Co-Cr-Ni alloy), and Ticonium 100 (Ni-Cr alloy), were evaluated in the as-cast condition and after heat treatment for 15 minutes at 1,300 degrees, 1,600 degrees, 1,900 degrees, and 2,200 degrees F followed by quenching in water. The following properties were determined and compared for each alloy at each heat treatment condition: the yield strengths at 0.01%, 0.1%, and 0.2% offsets, the ultimate tensile strength, the percent elongation, the modulus of elasticity, and the Knoop microhardness. The results were statistically analyzed. Photomicrographs were examined for each alloy and test condition. The following conclusions were made: 1. The "highest values" were exhibited by the as-cast alloy. 2. Heat treatment of the partial denture alloys tested resulted in reductions in strength, while the elongations varied. This study demonstrates that, in practice, one should avoid (a) prolonged "heat-soaking" while soldering and (b) grinding or polishing of the casting until the alloy is "red hot". 3. Durallium L.G. was the least affected by the various heat treatment conditions. 4. Conventional reporting of the yield strength at 0.2% offset, the ultimate tensile strength, and percent elongation are not adequate to completely describe and compare the mechanical behavior of alloys. The reporting of the yield strength at 0.01% offset, in addition to the other reported properties, will provide a more complete description of the behavior of the dental alloys.

The acrylic removable partial denture.

Some aspects of acrylic partial dentures have been reviewed. The spoon denture, the Every design, and the Lam design have been discussed and suggestions made for their construction and use for patients with specific problems.
