Enhancing Prosthetic Results by Predictable Impression Technique and Reliable NobelProcera™ Systems

2014-07-23 21:09:32 | BioPortfolio


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 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.


Background: Various implant impression techniques and materials have been proposed. Some clinical factors, such as the angulation or depth of implants, may affect the accuracy of the implant impressions. Lee et al. (Lee JPD 2008) reported that the splint-technique ensures a greater accuracy if compared to the non-splint technique, and, in case of 4 or more implants, the pick-up technique proves most appropriate. Polyether (PE) and VPS were the recommended materials for the implant impressions.

Aim: 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.

Medical and Biotech [MESH] Definitions

A snow sport which uses skis to glide over the snow. It does not include water-skiing.

Adherent debris produced when cutting the enamel or dentin in cavity preparation. It is about 1 micron thick and its composition reflects the underlying dentin, although different quantities and qualities of smear layer can be produced by the various instrumentation techniques. Its function is presumed to be protective, as it lowers dentin permeability. However, it masks the underlying dentin and interferes with attempts to bond dental material to the dentin.

Sports activities in the snow.

An apparently hereditary disorder of dentin formation, marked by a normal appearance of coronal dentin associated with pulpal obliteration, faulty root formation, and a tendency for peripheral lesions without obvious cause. (From Dorland, 27th ed)
