Chrome-cobalt disc with bridges and crowns manufactured using WorkNC Dental CAD/CAM. CAD/CAM dentistry is a field of dentistry and prosthodontics using CAD/CAM (computer-aided-design and computer-aided-manufacturing) to improve the design and creation of dental restorations, [1] [2] especially dental prostheses, including crowns, crown lays, veneers, inlays and onlays, fixed dental prostheses ...
An alternative technique uses a titanium root fused to a zirconia abutment by a sintering process that eliminates any possible microgap (which could cause peri-implantitis, leading to bone loss around the implant). [14] True 'root-form analogue' or 'anatomic' dental implants have been attempted in the past.
Resonance frequency analysis was first suggested as an alternative method of analyzing peri-implant bone in a scientific paper by Meredith N et al in 1996. [4] As stated in the paper’s abstract, in measuring implant stability and osseointegration, “radiographs are of value, but a standardised technique is necessary to ensure repeatability.” [4] The new technique tested involved ...
Dental implants are also used in orthodontics to provide anchorage (orthodontic mini implants). Orthodontic treatment [ 13 ] might be required prior to placing a dental implant. An evolving field is the use of implants to retain obturators (removable prostheses used to fill a communication between the oral and maxillary or nasal cavities). [ 12 ]
Between the direct and indirect, the direct digital impression technique was statistically more accurate, they showed significantly better inter-proximal contact. [6] The entire process proved to be more time efficient for both the dentist and patient in comparison with conventional methods or taking impressions with silicone impressions and ...
An impression body, made from alginate impression material. A custom dental model or plaster cast. A dental impression is a negative imprint of hard and soft tissues in the mouth from which a positive reproduction, such as a cast or model, can be formed. It is made by placing an appropriate material in a dental impression tray which is designed ...
Panoramic radiograph of historic dental implants, made 1978. Fauchard was the pioneer of dental prosthesis, and he invented many methods to replace lost teeth. He suggested that substitutes could be made from carved blocks of ivory or bone.
This dental radiograph displays two identical 5.0 mm diameter Biomet 3i tapered dental implants placed into the lower right mandible. The healing abutment on the more posterior implant [left] is platform matched (it shares the same 5.0 mm diameter as the implant platform), while the healing abutment on the more anterior implant [right] is platform switched (it possesses a 4.1 mm diameter).
