Summary

The purpose of this study is to evaluate the effectiveness of heavy Vinyl PolySiloxane (VPS) and splinted implants impression (Study Group, SG) technique versus plaster implant impression (Control Group, CG) technique, in 12 edentulous patients rehabilitated with the All-on-4/6 concept and Procera® Implant Bridge (P.I.B.). A longitudinal, double blinded, randomised clinical trial (RCT) was designed to evaluate the accuracy of the impression. All patients were monitored from implant placement until prosthetic loading.

Detailed description

The aim of the present study was to investigate the accuracy of pick-up, splinted implants, and heavy VPS impression techniques (Aquasil Putty DECA™ and Aquasil Ultra Light Viscosity (LV) Regular Set, Dentsply International Inc, Caulk, USA); to compare two splint materials for implants: Primopattern LC gel (Primotec, Bad Homburg, Germany), and Smart Dentin Replacement (SDR™, Dentsply International Inc, Caulk, USA); to examine the clinical factors affecting the accuracy of implant impressions; to test the tension-free fit of the new scanner and software NobelProcera™ (NobelBiocare, AB, Göteborg, Sweden) titanium frameworks.The hypothesis to demonstrate is that all impression techniques and used materials reduce time for final restoration and improve the accuracy of the impression.
