A Metal-Acrylic Bar for Splinting Implant Impression Copings
Precise transfer of three-dimensional position of dental implants from oral cavity to the cast needs special considerations in impression making. It has been suggested to splint the copings by bars or acrylic resin material before making impression. Some problems regarding to polymerization shrinkage of acrylic resin have been reported. In this study, we describe a metalacrylic bar tha...
متن کاملAccuracy of implant impression splinted techniques: effect of splinting material.
Three implant impression techniques, using 3 different splinting materials, were assessed for accuracy in a laboratory model that simulated clinical practice. For group A, an autopolymerizing acrylic resin was used to splint transfer copings. In group B, a dual-cure acrylic resin was used, and for group C, plaster, which was also the impression material, was used. A metal implant master cast wi...
متن کاملReusability of Implant Impression Copings-an in Vitro Study to Evaluate the Accuracy of Implant Transfer
INTRODUCTION: Implants are the mainstay of prosthetic dentistry nowadays. The number of accessory implant components essential for prosthetic rehabilitation are many. However De novo purchase of these components becomes an expensive treatment modality. So it becomes essential for the clinician to know about the reusability of these implant components without affecting the purpose served by them...
متن کاملComparison of implant cast accuracy of multiple implant impression technique with different splinting materials: An in vitro study
INTRODUCTION An accurate and passive fit of implant framework prosthesis, as well as the successful surgical operation is suggested as one of the critical requirements for long-term implant success. OBJECTIVE The purpose of this in vitro study was to evaluate the accuracy of the master cast using open tray impression technique with conventional and novel splinting materials. METHODOLOGY A m...
متن کاملEffect of Cervical Relining of Acrylic Resin Copings on the Accuracy of Stone Dies Obtained Using a Polyether Impression Material
The purpose of this study was to evaluate the accuracy of the respective dies after polyether elastomeric procedure in the presence or absence of cervical contact of the acrylic resin shell with the cervical region, establishing a comparison to dies obtained with stock trays. This study consisted of three groups with 10 specimens each: 1) acrylic copings without cervical contact, (cn); 2) acryl...
متن کاملretentiveness of implant-supported metal copings using different luting agents
background: with regard to potential retrievability of cement-retained implant restorations, the retentive strength of the luting agents is critical. the aim of this study was to evaluate the retention values of implant-supported metal copings using different luting agents. materials and methods: twenty iti implant analogs and solid abutments of 5.5-mm height were embedded vertically in autopol...
