“…Because of its low density, titanium dentures are more lightweight than conventional metal‐base dentures. It was reported that the difference in the weight of well‐fitting maxillary and mandibular titanium complete dentures did not affect jaw movements, denture stability or patient preference compared with conventional dentures (69, 70). However, the patients’ preferences were likely to be influenced by the preconceived idea that a heavy denture contributes to mandibular denture stability and that light maxillary dentures are hard to remove.…”

“…However, the patients’ preferences were likely to be influenced by the preconceived idea that a heavy denture contributes to mandibular denture stability and that light maxillary dentures are hard to remove. Thus, titanium maxillary dentures may be preferred by the patients who have such preconceived ideas (69). On the other hand, facial prostheses should be fabricated as light as possible because they cannot be given enough retention (71).…”

Although porcelain and zirconium oxide might be used for fixed partial dental prostheses instead of conventional dental metals in the near future, removable partial denture (RPD) frameworks will probably continue to be cast with biocompatible metals. Commercially pure (CP) titanium has appropriate mechanical properties, it is lightweight (low density) compared with conventional dental alloys, and has outstanding biocompatibility that prevents metal allergic reactions. This literature review describes the laboratory conditions needed for fabricating titanium frameworks and the present status of titanium removable prostheses. The use of titanium for the production of cast RPD frameworks has gradually increased. There are no reports about metallic allergy apparently caused by CP titanium dentures. The laboratory drawbacks still remain, such as the lengthy burn-out, inferior castability and machinability, reaction layer formed on the cast surface, difficulty of polishing, and high initial costs. However, the clinical problems, such as discoloration of the titanium surfaces, unpleasant metal taste, decrease of clasp retention, tendency for plaque to adhere to the surface, detachment of the denture base resin, and severe wear of titanium teeth, have gradually been resolved. Titanium RPD frameworks have never been reported to fail catastrophically. Thus, titanium is recommended as protection against metal allergy, particularly for large-sized prostheses such as RPDs or complete dentures.

The use of a single metal for all restorations would be necessary because it protects against metal corrosion caused by the contact of different metals. For this "one-metal rehabilitation" concept, non-alloyed commercially pure (CP) titanium should be used for all restorations. Titanium frameworks have been cast and used for the long term without catastrophic failure, whereas they have been fabricated recently using computer-aided design/computer-aided manufacturing (CAD/CAM). However, the milling process for the frameworks of removable partial dentures (RPDs) is not easy because they have very complicated shapes and consist of many components. Currently, the fabrication of RPD frameworks has been challenged by one-process molding using repeated laser sintering and high-speed milling. Laser welding has also been used typically for repairing and rebuilding titanium frameworks. Although laboratory and clinical problems still remain, the one-metal rehabilitation concept using CP titanium as a bioinert metal can be recommended for all restorations.

“…TI‐retained overdentures were fabricated by converting the existing mandibular complete dentures of seven mandibular edentulous patients. To observe the stability of the TI‐stabilized overdentures (24–28), masticatory movements (mandibular movements during chewing) were measured before and after TI placement, and the patients were questioned about the function of each denture.…”

summary Transitional implants (TI) can immediately improve the stability and retention of existing unstable mandibular complete dentures. This study evaluated the improvement of mandibular complete denture stability and retention with the use of TI. Three TIs were placed in the intraforaminal region of the edentulous mandible of seven patients (three men, four women; mean age 69·7 years). The patients’ existing mandibular complete dentures were immediately modified to TI‐stabilized overdentures. Their masticatory movements (mandibular movements during mastication) were measured using a commercially available tracking device (BioPACK, Bioresearch, Japan), both before TI placement and about 1 month after delivery of the TI‐stabilized overdentures. The mean time of each chewing phase (opening, closing, and occluding) and coefficients of variation were calculated. The patients also completed a questionnaire about the foods they could chew and indicated on a 100 mm Visual Analog Scale (VAS) their personal levels of comfort, ease of chewing, speech, and stability. For masticatory movements, there were no significant differences (P > 0·05) between the TI‐stabilized overdentures and existing complete dentures. However, the number of foods that could be chewed increased, and the stability and comfort were reported as improved with the TI‐stabilized overdentures. Using TIs, the stability and comfort of the existing mandibular complete dentures studied in this report could be immediately improved.

The Effect of Weight Change of Maxillary Complete Denture on Masticatory Movement.

Abstract: This study was conducted to investigate the effect of weight change of upper complete denture on masticatory function in case of five maxillary edentulous patients who had adequate retention and stability.
