•Complete Denture: a removable dental prosthesis that replaces all of the natural teeth in the maxillary or mandibular dental arch. The denture is usually made of methyl methacrylate and is completely supported by the mouth tissues.

•Baseplate (Record Base): The portion of an artificial denture in contact with the jaw. A temporary form representing the base of a denture and used to help establish jaw relationships and the arrangement of teeth.

•Bite rim: a border constructed on temporary or permanent denture bases in order to record the maxillomandibular relation and for positioning of the teeth.

•Border molding: the shaping of an impression material by the manipulation or action of the tissues to determine the denture border position.

•centric occlusion:  that in the vertical and horizontal position of the mandible in which the cusps of the mandibular and maxillary teeth interdigitate maximally.

•denture base: the material in which the teeth of a denture are set and which rests on the supporting tissues when the denture is in place in the mouth.

•Border molding (muscle trimming): the shaping of an impression material by the manipulation or action of the tissues to determine the denture border position.

•Over [lay] Denture: a complete denture supported both by soft tissue (mucosa) and by a few remaining natural teeth that have been altered, as by insertion of a long or short coping, to permit the denture to fit over them.

•Vertical Dimension: a vertical measurement of the face between any two arbitrarily selected points that are conveniently located one above and one below the oral cavity, usually in the midline.

•Centric Jaw Relation: the relation of the mandible to the maxillae when the condyles are in their most posterosuperior unstrained positions in the glenoid fossae, from which lateral movements can be made at the occluding vertical relation normal for the individual. Centric relation is a relation that can exist at any degree of jaw separation.

•Occlusal Relationship: the individual and collective relationships of the mandibular teeth to the maxillary teeth and the relationship of the adjacent teeth in the same dental arch.
