摘要：Although porcelain and zirconium oxide may be utilized instead of traditional dental metals for fixed partial dental prostheses in the near future, biocompatible metals will most likely continue to be used for RPD frameworks. Commercially pure (CP) titanium offers suitable mechanical qualities, is lighter (low density) compared to traditional dental alloys, and has excellent biocompatibility, preventing metal allergies. The laboratory conditions required for synthesizing titanium frameworks are described in this review, as well as the current status of titanium removable prosthesis. Titanium is progressively being used in the fabrication of cast RPD frameworks. There have been no reports of metallic allergies linked to CP titanium dentures. The long burn-out, inferior castability and machinability, reaction layer generated on the cast surface, polishing difficulty, and high initial costs are still some of its laboratory drawbacks. However, clinical issues such as discolouration of titanium surfaces, harsh metal taste, decreased clasp retention, plaque adhesion to the surface, denture base resin detachment, and severe wear of titanium teeth have gradually been rectified. There have never been any reports of titanium RPD frameworks failing severely. As a result, titanium is advised as a protection against metal allergy, particularly for large prostheses like RPDs or complete dentures.
