Fatigue Evaluation of a New Two-Piece Dental Implant, Having a Replaceable Titanium Sleeve

A new two-piece dental implant, having a replaceable thin titanium sleeve in its 5 mm crestal part was designed. The use of a sleeve of near 0.2 mm thickness reduces implant diameter by 0.4 mm. Narrower diameter implants may increase the likelihood of component fracture in dental implant systems. 14 two-piece dental implants, with 25 deg abutment angle were subjected to a dynamic fatigue test according to DIN EN ISO 14801. The highest load at...
