The applications of various technological advances in implant dentistry and in all aspects of the diagnostic, treatment planning, surgical, and restorative phases are gaining popularity. Additive rapid prototyping and computer-aided design/computer-aided manufacturing (CAD/CAM) technology are used to generate stereolithographic surgical guides and(More)
Surgical and prosthodontic implant complications are often an inadvertent sequelae of improper diagnosis, planning, and placement. These complications pose a significant challenge in implant dentistry. Presented in this article is a technique using a highly advanced software program along with a rapid prototyping technology called stereolithography. It(More)
Eight implants were placed in the posterior part of the mandible using computer-generated stereolithographic templates. Preoperative implant simulation was done on a 3D computer model created by reformatted computerized tomography data. The surgeon and the prosthodontist positioned the simulated implants in the most favorable position addressing all(More)
OBJECTIVE To report the clinical results and technical complications with computer-assisted design/computer-assisted manufacturing (CAD/CAM) zirconia, implant fixed complete dental prostheses (IFCDPs) after 2-4 years in function. MATERIALS AND METHODS Fourteen consecutive edentulous patients (16 edentulous arches) were included in this study. Ten of the(More)
UNLABELLED Immediate loading in implant dentistry has provided several advantages for both patients and clinicians. Recent advances in computer-aided design/computer-aided manufacturing (CAD/CAM) technology, medical imaging and rapid prototyping have added to the armamentarium of implant dentistry in terms of efficiency, accuracy and predictability. Rapid(More)
Papaspyridakos and Lal Papaspyridakos and Lal The dental literature is replete with techniques for registering maxillomandibular relationships and transferring them accurately to the articulator. For edentulous patients receiving implants, several methods have been described for articulating the definitive implant cast at the appropriate occlusal vertical(More)
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;(More)
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(More)
Computer-guided flapless surgery for implant placement using stereolithographic templates is gaining popularity. The advantages of this surgical protocol are its minimally invasive nature, accuracy of implant placement, predictability, and reduced time required for definitive rehabilitation. One of the disadvantages, however, pertains to complete arch(More)
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(More)
