| malleability | ability of a material to be pressed or hammered out into various forms and shapes |
| elongation | ability of a material to stretch before permanent deformation begins |
| inlay | a solid casted or milled restoration involving some occlusal and proximal surfaces that is cemented into a tooth preparation |
| onlay | a solid casted or milled restoration that covers some occlusal tooth cusp and side wall area that is cemented onto the perpared site |
| crown | a fabricated, tooth-shaped cover replacement for a missing crown area that is cemented onto the remaining prepared crown surfaces |
| full crown | cast metal, tooth-shaped cover that replaces the entire crown area |
| jacket crown | thin, preformed, metal shield used to cover a large area of anterior crowns |
| dowel crown | full crown coer with dowel pin extending into the root canal of a pulpless tooth, usually positioned on anterior teeth |
| three-quarter crown | simialr to full crown, covering all of the crown except the facial surface of the tooth that remains intact, to present an esthetic natural appearance |
| porcelain-fused-to-gold (PMF) | crown that has a complete capping of metal base with fused porcelain to metal, giving tooth contour, shape, and cover |
| direct veneer | is placed and cured directly on the tooth surface to build up the area or replace missing tooth structure |
| indirect veneer | tooth material is prepared in the lab and later cemented onto the tooth structure |
| bridge | a prosthesis used to replace one or more teeth |
| fixed bridge | cemented into the oral cavity and not removed by the parient; the number of teeth involved in the appliance determines the number of units |
| Maryland bridge | replaces anterior or posterior tooth and is cemented directly to the adjacent or abutting teeth; also called resin-bonded bridge |
| cantilever bridge | bridge with unsupported end, usually saddled |
| pontic | artificial tooth part of the bridge that replaces the missing tooth and restores function to the bite |
| abutment | natural tooth or teeth that are prepared to hold or support the retaining part of the bridgework in position |
| adjacent | (nearby or adjoining) may be included in units if they are involved in the bridge area |
| complete denture | (removable appliance composed of artificial teeth set in an acrylic base) full denture designed to replace the entire dentition of an upper or lower arch |
| partial denture | removable appliance, usuallt composed of framework, artificial teeth, and acrylic material; replaces one or more teeth in an arch |
| immediate denture | denture prosthesis that is placed into the mouth at the time the natural teeth are surgically removed |
| overdenture | prosthetic denture that is prepared to fit and be secured upon implant posts or prepared retained roots |
| framework | metal skeleton or spine onto which a removable prosthesis is constructed |
| saddle | the part of the removable prosthesis that strides or straddles the gingival crest; used to balance the prosthesis, and serves as a nase for placement of artificial teeth |
| rests | small extensions of removable prosthesis made to fit fit or sit atop the adjoinging teeht; provide balance and stability for the partial denture appliance |
| clasp | extension of partial framework that grasps the adjoining teeth tp provide support and retention of the prosthesis |
| retainer | in fixed prosthesis, the part of the appliance that joins with the abutting, natural tooth to support the appliance, like the pillar holding the span of a bridge over the water |
| connector | (device used to unite or attach two or more parts together) used to connect quadrants of a partial denture or connect and support an overdenture |
| stress breaker | a connector applied in stress-bearing areas to provide a safe area for breakage |
| artificial teeth | anatomical substitiutes for natural teeth; made of porcelain or acrylic material in carious shades and shapes, called molds |
| denture base | acrylic part of the denture prosthesis that substitutes for the gingival tissue |
| flange | projecting rim or lower edge of prosthesis |
| post dam | posterior edge of the maxillary denture; helps to maintain the denture and suction |
| elastomeric | having properties similar to rubber |
| hydrocolloids | (water, suspension) an impression material that is both recersible and irreversible |
| reversible hydrocolloids | impression material that can change from a solid or gel state to a liquid form and back again, depending upon temp. changes |
| thermoplastic | (heat, moveable) quality of a material that changes from a rigid to plastic or movable form as a result of aapplication of heat |
| irreversible hydrocolloid | quality that , once chemically set or in gel form, cannot be reversed or used again |
| imbibition | fluid absorption |
| extruder gun | calibrated mixing dispenser |
| compound | a non-elastic impression material that may be used in edentulous impressions |
| alveolectomy | surgical removal of alveolar bone crests may be required to provide smooth alveolar ridge for denture seating |
| alveoplasty | surgical reshaping or contouring of alveolar bone |
| extraction | surgical removal of teeth |
| template | guide or pattern |
| coping | (coverings) metal cover placed over placed over the remaining natural tooth surfaces to provide attachments for overdentures |
| reduction | (reducing) removal of tooth decay and surfaces to receive the appliance |
| chamfer | (tapered margin at tooth cervix) preparation for crown placement |
| shoulder | (cut gingival margin edge) preparation to provide junction of the crown and tooth |
| bevel | (slanted edge) tooth preparation for seating and holding a crown |
| core buildup | use of synthetic material to enlarge tooth core area to provide support for an artificial crown and to protect the pulpal tissues |
| post placement | addition of a metal retention post to teeth that have had pulp removal and root canal enlargement, to aid in stability and strength |
| undercut | removal of tooth structure near the gingival edge to provide a seat or placement for the extending edge of the appliance |
| retraction cord | chemically treated cord placed in the gingival sulcus to obtain chemical or physical shrinking of the gingiva |
| inpregnated | (saturated) |
| bite registration | impression of teeth while they are in occlusion |
| open bite | patient bites into the impression material |
| closed bite | the material in injected and expressed around the desired teeth while they are in occlusion |
| opposing arch | impressions of the occlusal surfaces of both arches are taken in the same procedure |
| work order | written directions from the dentist to the laboratory completing the case |
| temporary or provisional coverage | temporary protection for the prepared tooth while laboratory wirk is being completed |
| seating | placement and fitting of appliance for try-in and final cementation. The patient bites on a stick or device, applying pressure for application of the crown or prosthetic item |
| condular inclination | (pertaining to the condyle) observation of bite relationship and TMJ involvement |
