faulty restoration

faulty restoration

[fôl′tē]

Etymology: L, fallere, to deceive, restaurare, to renew

any dental filling or fabrication that contains flaws, such as overhanging or incomplete fillings, voids, and incorrect anatomic characteristics of occlusal and marginal ridge areas. Such flaws may mar individual tooth fillings and fixed bridges or clasps of removable prosthetics and may cause inflammatory and dystrophic diseases of the teeth and periodontium. See also restoration.

restoration,

n (prosthetic restoration), broad term applied to any filling, inlay, crown, bridge, partial denture, or complete denture that restores or replaces lost tooth structure, teeth, or oral tissues; a prosthesis.

restoration, amalgam,

n a direct restoration made from an alloy consisting of mercury and other metals (e.g., silver, copper, or tin), which is carved and contoured after placement in the tooth; allow a minimum of 24 hours between placement and polishing.

Amalgam restoration.

restoration, ceramic,

n an indirect restoration made from metal and nonmetal compounds, which is carved and contoured before placement in the tooth; closely resembles natural teeth in strength, hardness, chemical inertness, and esthetic appearance.

restoration, dental prosthetic,

n See prosthesis, dental.

restoration, direct,

n a restoration prepared for immediate application to the tooth or cavity, as opposed to one prepared on a diagnostic cast and applied later.

restoration, faulty,

n restoration in which there are imperfections or incorrect attributes (e.g., overhanging or deficient fillings, incorrect anatomy of occlusal and marginal ridge areas, faulty clasps). Such faults may be present in individual tooth restorations, fixed bridges, and removable partial dentures and are conducive to the initiation and perpetuation of inflammatory and dystrophic diseases of the teeth and periodontium.

restoration groove,

n an opening between the restoration and the tooth structure, which results from either a broken flash or a material contraction; may also be called
ditch.

restoration, implant,

n the single-tooth implant crown or multiple-tooth implant, crown, or bridge that replaces a missing tooth or teeth.

restoration of cusps,

n (preferred to tipping, capping, or shoeing cusps), reduction and inclusion of cusps within a cavity preparation and their restoration to functional occlusion with restorative material.

restoration, overcontoured,

n a restoration containing so much excess restorative material that normal anatomic structure is altered; may cause plaque retention and open or deficient gingival margin.

restoration, PFM,

n also called a
porcelain-fused-to-metal restoration. A restoration made up of a metal substructure covered by an esthetic ceramic coating.

restoration, porcelain,

n an indirect restoration made from a ceramic material that is cast in a laboratory prior to insertion in the oral cavity and finished during placement. See also ceramic restoration.

Porcelain restoration.

restoration, prosthetic,

n See prosthesis.

restoration, temporary,

n an artificial prosthesis used for a limited period to provide protective function and esthetics until a definitive prosthesis can be fixed into place.

restoration, undercontoured,

n a restoration containing too little restorative material so that a space occurs between the margin and the cavity wall; may result when either the matrix band or wedge is improperly placed.
