abutment, custom,
n a custom-made post attached to the superior part of the metal dental implant that protrudes through the gingival tissues and onto which the restoration is fitted; either machined or cast, and used in situations where prefabricated abutments cannot be used.
abutment, healing,
n a cylinder or screw used during the second stage of dental restoration. This serves two purposes: to allow gingival tissues to heal prior to the placement of the permanent abutment, and to maintain proper spacing in the oral cavity before the final restoration (prosthesis) is placed.
abutment, intermediate,
n an abutment located between the abutments that form the ends of the prosthesis.
abutment, multiple,
n abutments splinted together as a unit to support and retain a fixed prosthesis.
abutment, prefabricated,
