Lec 1.1: Terminologies Flashcards
It is a device worn by a patient in the course of treatment (orthodontic appliance, space maintainer).
Appliance
A tooth, portion of a tooth, that portion of dental implants that serves to support and or retain a prosthesis.
Abutment
The fixation device, or any form of attachment applied directly to an abutment tooth and used for the fixation of a prosthesis.
Retainer
The retention of this prosthesis depends on the exact parallelism of the 2 retentive units.
Extracoronal partial denture
A partial denture that receives support from the natural teeth at each end of the edentulous space/s.
Tooth supported RPD
The denture base that extends anteriorly / posteriorly and is supported by teeth at one end and tissue on the other end (distal extension partial dentures).
Tooth tissue supported RPD
They are used in patients where tissue changes are expected, where a permanent prosthesis cannot be fabricated until the tissue stabilize.
Temporary removable partial denture
A temporary partial denture used for a short period to fulfill esthetics, mastication or convenience until a more definite form of treatment can be rendered.
Interim denture
A denture used for a short interval of time to provide:
a. esthetics, mastication, occlusal support and convenience.
b. conditioning of the patient to accept the final prosthesis.
Interim denture
Used when loss of additional teeth is inevitable but immediate extraction is not advisable or desirable. Artificial teeth may be added to the denture as and when the natural teeth are extracted.
Transitional denture
It is used when the soft tissue have been abused by ill-fitting prosthetic devices.
Treatment denture
It is the most posterior relation of mandible to the maxilla at the established vertical dimension from which lateral movements could be made.
Centric relation
It is the maximum inter-cuspation between the upper and lower teeth.
Centric occlusion
Relationships of the mandible to maxilla other than centric relation, that occur in horizontal plane (protrusive, right lateral, left lateral).
Eccentric relation
Defined as the “branch of dentistry” pertaining to the restoration and maintenance of the oral function, comfort, appearance and health of the patient by restoration of natural teeth or the replacement of missing teeth and “contiguous” oral and maxillo-facial tissues with an artificial substitution.
