Machined short implants have been around since the 1980s but their high failure rate was used to justify sinus lifts; block grafts etc. Only with the newer micro-roughened surfaces have short implants been seen to be as successful as longer ones. In challenging cases where a residual ridge exhibits severe horizontal or vertical bone defects or when placement of an implant is limited by anatomical structures, short implants may be considered a practical option and may avoid the need for further extensive surgical procedures.enCrown-implant ratioSingle crownAnalysisPosterior maxillaMandibleArticle
