CAD/CAM systems (CAD = computer aided design, CAM = computer aided manufacturing) are used in addition to the manual techniques of producing dental restorations. The computer produces a virtual copy of the tooth stump and then mills the final restoration from a blank (metal, ceramic or acrylic) with the aid of the data.
CAD/CAM system manufactured by Sirona GmbH, Bensheim, Germany, for patient-specific all-ceramic restorations in just a single session. The system comprises a mobile PC with an integrated flat panel display. A 3D camera enables precise measurement of the tooth. The dentist then uses this data to construct a precision-fit filling or crown directly on-screen. In approximately ten minutes, a separate milling machine grinds the restoration from a ceramic block.
Bridge where one pontic is located outside of the supporting framework between the bridge abutments, and is not supported on the other side by a further pillar.
Acute or chronic decay of the hard tooth substance (tooth decay). Caries (tooth decay) is caused by a chemical process which can be avoided if adequate oral hygiene is ensured.
In dentistry mostly non-metallic, inorganic materials that â€“ due to their advantages such as tissue friendliness, natural appearance, high biocompatibility, shade stability, hardness, chemical resistance â€“ serve as the basis for artificial teeth, tooth-colored dentures, fillings and implants.
Vestibular margin specific to metal-ceramic crowns that is fabricated from ceramic rather than metal. Its use requires the preparation of a ridge upon which the ceramic is directly seated and supported. By fitting crowns with a ceramic shoulder, the dark edge often noticeable at the gum line can be avoided.
Removable, esthetically less sophisticated denture which is fixed at the remaining dentition by means of clasps acting as retaining and supporting elements.
Filling materials for the treatment by the dentist composed of an organic plastic matrix mixed with inorganic filler particles. Composite is mainly applied in the area of the anterior teeth (â€œwhite fillingâ€). Today, composite is also used in the area of the posterior teeth, mostly with promising results.
Replaces lost or diseased tooth substance using tooth-colored composite. These fillings offer superior esthetics, and if fitted correctly, only dental professionals can distinguish them from the real thing.
Complete covering of a tooth for a severely damaged tooth with a substance which is still worth to be preserved.
Distinguishing feature for determining whether a tooth belongs to the right or left half of the jaw.
Crown that completely consists of metal (usually gold) and that is not veneered in tooth shade.
Part of the tooth that covers the dentine in the root area. It is part of the periodontic apparatus and consists of minerals, collagen fibers, cementocyts and water. The basic substance of the cementum is therefore similar to that of the fiber bone.
