抄録

Several less-invasive intervention techniques for single or several missing teeth, e.g., a fixed partial denture supported by resin-bonded cast retainers, single-standing bone-anchored prosthesis, have been advocated to recover its functionality. However, the non-invasiveness of the techniques could never be estimated sufficient in consideration of risk-benefit. Recently, we developed a fixed partial denture supported by tiny shape memory alloy (Ti-Ni alloy) pins attached to proximal surfaces of abutment teeth by an adhesive composite resin cement. Strong retention of the tiny proximal pins could be accomplished by the morphological recovery within the Titanium-nickel shape memory alloy end and excellent adhesivity of the adhesive resin, tooth surfaces, and Ti-Ni alloy. A pontic for the prosthesis was permanently fixed with an adhesive composite resin cement and estimated functional recovery were excellent under a small amount of tooth reduction. The special advantages of this method were the excellent less-invasiveness of the total procedure and the promised long-term durability.
