Total CAD/CAM Supported Method for Manufacturing Removable Complete Dentures.

The incorporation of computer-aided design/computer-aided manufacturing (CAD/CAM) technology into complete denture fabrication brings about several advantages to the fabrication process, providing better predictability of the desired outcomes and high accuracy of denture fit, mainly because the milling of prepolymerized acrylic resin eliminates the shrinkage of the acrylic base. Also, there is a decrease in the porosity when compared to a conventionally processed denture, and consequently there is a decrease in the retention of on the denture base. The presented workflow for complete denture fabrication presents a totally wax-free manufacturing process, combining rapid prototyping (RP) and rapid milling.

Treatment of the edentulous patient.

For decades the edentulous population has been unrecognized in its need to be treated in an effective manner. The debilitating condition affects quality of life. Implants have provided a strategy for developing a standard of care.

Flapless CAD/CAM-guided surgery for staged transition from failing dentition to complete arch implant rehabilitation: a 3-year clinical report.

The transition of patients from failing dentition to complete arch implant rehabilitation often requires that the patient be rendered edentulous and has to wear a complete removable dental prosthesis for varying periods of time. This is objectionable to many patients. A staged treatment approach allows a fixed interim restoration, patient comfort, and prosthodontic control throughout the rehabilitation process.

Effect of splinted and nonsplinted impression techniques on the accuracy of fit of fixed implant prostheses in edentulous patients: a comparative study.

Purpose: The effect of different implant impression techniques on the accuracy of casts has been investigated mostly in vitro, and clinically relevant evidence is scarce. The purpose of this study was to investigate the effect of implant impression techniques--specifically, splinted versus nonsplinted--on the accuracy of fit of fixed implant prostheses in edentulous patients.

Materials And Methods: This clinical study included 12 edentulous patients (13 edentulous arches).

Accuracy of implant casts generated with splinted and non-splinted impression techniques for edentulous patients: an optical scanning study.

Background: The accuracy of implant casts generated with various impression techniques was mainly investigated in vitro resulting in limited clinical data.

Purpose: (1) To compare the three-dimensional (3-D) accuracy of splinted and non-splinted impression techniques to the control casts (verification jigs) that had been used for actual patient treatment; and (2) to determine the maximum level of clinically undetectable misfit. The null hypothesis was that there would be no significant difference in the accuracy of casts generated with different impression techniques.
