The Triple Tray is a type of plastic tray used for taking impressions for a crown using the double arch or dual bite impression technique. It is used for taking impressions of the tooth preparation and the opposing teeth, by the use of a special impression material, usually elastomer.
The tooth has not fully erupted and continued active and passive eruption can cause unfavourable margins when the tooth is fully through as the patient is still undergoing skeletal development. Young children may be unable to cope with invasive dental treatment and long procedures, therefore it is advantageous to wait until they are fully ...
Once the tooth in question has been prepared with acceptable dimensions, it is equally important to make an accurate and dimensionally stable record or impression of the preparation or dental implant, surrounding hard and soft tissues as well as the opposing dental arch so that the restoration created will conform to the required dimensions 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 ...
The polymer solution casting process utilizes a mandrel, or inner diameter mold, that is immersed in a tank of polymer solution or liquid plastic that has been specifically engineered for the process. Due to a combination of thermal and frictional properties, the polymer solution then forms a thin film around the mold. [1]
An all-electric injection unit with 14 mm screw to inject the polymer melt into the mold; Arburg developed a micro injection molding machine with an 8 mm injection to ensure high degree of dosing precision. This type of machine is combined with a second screw, which is responsible for melting and homogenous mixing of the material. [2]
The process of preparation usually involves cutting the tooth with a rotary dental handpiece and dental burrs, a dental laser, or through air abrasion (or in the case of atraumatic restorative treatment, hand instruments), to make space for the planned restorative materials and to remove any dental decay or portions of the tooth that are ...
Gum grafting, also known as a gingival graft or periodontal plastic surgery, is a surgical procedure to reverse gum recession. Gum recession exposes the roots of teeth, [9] which can lead to sensitivity and put teeth at a higher risk of damage or disease [10] due to the loosening of their attachment within the gums and bones of the jaw.
