The Periotest method: implant-supported framework precision of fit evaluation.
PURPOSE In this study, the Periotest instrument was used to measure the precision of fit between cast high noble-metal frameworks and the supporting implants in a patient-simulation model. Three framework conditions and three implant-location variables were used to evaluate the rigidity of the assembly as measured by the Periotest method. The framework variables were (1) one-piece castings (OPC...
متن کاملFit to Electroweak Precision Data
A brief review of electroweak precision data from LEP, SLC, the Tevatron, and low energies is presented. The global fit to all data including the most recent results on the masses of the top quark and the W boson reinforces the preference for a relatively light Higgs boson. I will also give an outlook on future developments at the Tevatron Run II, CEBAF, the LHC, and the ILC. The Higgs boson re...
متن کاملA method to improve passive fit of frameworks on implant-supported prostheses: an in vivo study.
PURPOSE A die stone jig was evaluated as to its ability to clinically verify the position of the abutment replicas on the master cast. MATERIALS AND METHODS A clinical evaluation was made on 58 edentulous arches necessitating rehabilitation with fixed partial dentures. Any broken jigs detected were replaced with a new set of jigs and clinically retested. Data were statistically confirmed. R...
متن کاملEvaluation of Electric Discharge Machining to achieve Passive Fit of Implant Superstructure: An in vitro Study
Objective: To evaluate marginal discrepancies between cast implant superstructure and EDM processed implant structure. Materials and methods: For the purpose of this study, an experimental model was prepared on which nine cast implant superstructure in nickel-chromium were fabricated which was then subjected to EDM processing. One-screw test was used to verify fit of superstructure both preand ...
متن کاملDigital vs. conventional implant impressions: efficiency outcomes.
OBJECTIVES The aim of this pilot study was to evaluate the efficiency, difficulty and operator's preference of a digital impression compared with a conventional impression for single implant restorations. MATERIALS AND METHODS Thirty HSDM second year dental students performed conventional and digital implant impressions on a customized model presenting a single implant. The outcome of the imp...
