Cemented vs. screw-retained restorations on dental implants

Abstract

Aim and objectives: Implants represent a growing business all over the world. As more and more dentists tend to treat patients using this kind of treatments, the complications are also much more common as time goes by. The prosthetic solutions are various, they include single/multi-unit restorations, cemented or screw-retained on a variety of abutments and ti-bases. The aim of this study is to compare the two choices - cemented vs screw-retained and follow up the tissue response after replacing an old cemented restoration with a screw-retained one. Materials and methods: A patient with cement-related peri-implantitis was treated and followed over a period of time. Tissue response was analysed as healing and bio-integration of the new restoration occurred. Results: Tissue healing and maturation progressed very well after the irritation caused by the cement was removed. Conclusions: Cemented implant restoration pose a higher threat of peri-implantitis compared to the screw-retained ones due to the risk of cement overpass into the peri-implant space.
