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 ...
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 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 ...

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 ]
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.
Impressions can be made digitally or by conventional technique. With regards to conventional impression techniques, the materials selected should have appropriate physical properties and handling characteristics to allow enough detail reproduction and durability when casting a model, including the ability to withstand effective decontamination ...
Dental impressions are negative imprints of teeth and oral soft tissues from which a positive representation can be cast. They are used in prosthodontics (to make dentures ), orthodontics , restorative dentistry , dental implantology and oral and maxillofacial surgery .
