Influence Of Free-End Distal Extension On The Accuracy Of Guided Implant Placement: An In Vitro Study, Geoffrey Ganzman
Master's Theses (2009 -)
Purpose: The aim of this study was to evaluate the influence of type of tooth-support (bounded edentulous space versus unbounded edentulous spaces) on the accuracy of fully-guided implant placement using static computer-assisted implant surgery (sCAIS) in partially-dentate patients. Methods: Four different clinical scenarios were simulated; (a) bounded single-tooth edentulous space (BES), and three different free-end distal extensions with (b) unbounded single-tooth edentulous space (UBES1), (c) unbounded two-teeth edentulous space (UBES2), and (d) unbounded three-teeth edentulous space (UBES3). An implant planning software was used to design 3D-printed stereolithographic surgical guides for the respective clinical scenarios. In total n=140 implants with dimensions …
