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 ...
Miscellaneous endodontic instruments. From left: Lentulo spiral, reamer, K-file and H-file. Hand files can provide tactile sensation when cleaning or shaping root canals. This allows the dentist to feel changes in resistance or angulation, which can help determine curvature, calcification and/or changes in anatomy, in which two dimensional radiographs may not always identif
Air turbine used in a dental handpiece Correlation between rotational speed and torque Correlation between rotational speed and turbine output power. The turbine is powered by compressed air between 35 and 61 pounds per square inch (~2,4 to 4,2 bar), [1] [2] which passes up the centre of the instrument and rotates a Pelton wheel in the head of the handpiece.
CAD-CAM (aka Computer Aided Design-Computer Aided Manufacture) is a fabrication method which aids the production of dental restorations e.g. crowns, bridges, inlays and onlays. It is possible for these indirect restorations to be provided in one visit. [25] This works by first taking an intra-oral scan to produce a 3D virtual impression.
A Lentulo spiral. The notches at left allow it to fit into a slow-speed latch handpiece. A Lentulo spiral is a dental instrument used to properly distribute root canal sealer and cement evenly throughout the root canal system, as when performing endodontic therapy or a post and core cementation.

When the lower jaw is pushed anteriorly as far as possible with some teeth in contact, it is said to be maximum protrusion. In Posselt's border movement diagram, maximum protrusion is the most anterior based on the sagittal view. Condyles are in the most anterior position and determined partly by stylomandibular ligaments. [8]
Dental aerosol from a dental hand piece. A dental aerosol is an aerosol that is produced from dental instrument, dental handpieces, three-way syringes, and other high-speed instruments. These aerosols may remain suspended in the clinical environment. [1] Dental aerosols can pose risks to the clinician, staff, and other patients
