Presentation Transcript

  1. An RCT comparing guided implant surgery (bone or mucosa supported) with mental navigation or the use of a pilot-drill template Vercruyssen M, Cox C, Coucke W, Naert I, Jacobs R and Quirynen M. J ClinPeriodontol 2014;E-pub Jan 28, doi:10.1111/jcpe.12231 • 59 patients were randomized into 6 groups as follows: Guiding systems1) Universal bone,2) Universal mucosa,3) Facilitatebone, 4) FacilitatemucosaControls 5) Mental navigation 6) Template pilot drill • Planning in SIMPLANT software usingimported MSCT scans • Fabricationof all stereolitographic guides wasdone by DENTSPLY Implants • 314 OsseoSpeed implants were placed (4 implants in mandible, 6 implants in maxilla) • Pre and postoperative scans were compared in Mimics software (Materialise) • Outcome variables (deviation): a) entry point, b) angular deviation, c) apex point Aim Evaluate the accuracy of stereolithographic surgical drill guides Materials & Methods VercruyssenM, et al. An RCT comparing guided implant surgery (bone or mucosa supported) with mental navigation or the use of a pilot-drill template. J ClinPeriodontol 2014;E-pub Jan 28, doi:10.1111/jcpe.12231

  2. An RCT comparing guided implant surgery (bone or mucosa supported) with mental navigation or the use of a pilot-drill template Results - Largerdeviation in lowerjaw and in poorqualitybone - No influenceoftypeof support, i.e. bone vs. mucosa or Universal vs. Facilitate Deviation: Conclusion • Guided surgery has an added value and shows smaller deviations compared to mental navigation or using a template for guide drills Vercruyssen M, et al.
