Introduction to Prosthodontics

Prosthodontics

Branch of dentistry pertaining to the restoration and maintenance of oral function, comfort, appearance and health of the patient by restoration of natural teeth or the replacement of missing teeth and contiguous oral and maxillofacial tissues with the artificial substitution.

Removable Prosthodontics

It is devoted to replacement of missing teeth & contiguous tissues with prosthesis designed to be removed by the wearer.

Removable Complete Denture - Removable Partial Denture

What are the 2 disciplines of removable prosthodontics?

Partial Denture

It is devoted to replacement of missing teeth & contiguous tissues with prosthesis designed to be removed by the wearer.

Removable Partial Denture (RPD)

It is devoted to replacement of missing teeth & contiguous tissues with prosthesis designed to be removed by the wearer.

Removable Partial Denture (RPD)

Prosthesis which extends the partial edentulous phase to its maximum limit to avoid complete edentulism.

Temporary RPD (all-resin) - Definitive Cast Framework RPD

RPD can be in the form of (2)?

Prosthesis

An artificial replacement for a missing body part.

Dental Prosthesis

An artificial replacement for a missing body part.

Abutment

An artificial replacement for a missing body part.

Retainer

Portion of a fixed or removable partial denture that attaches the prosthesis to an abutment

Fixed Prosthodontics - Removable Prosthodontics - Maxillofacial Prosthodontics

What are the 3 branches of prosthodontics?

Provisional/Temporary RPD

A denture used for a short interval of time to provide esthetics, mastication, occlusal support and convenience.

Provisional/Temporary RPD

denture used for a short interval of time to provide conditioning of the patient to accept the final prosthesis.

Definitive RPDs

RPD constructed after extensive diagnosis, treatment planning, and thorough preparation of the teeth and tissues for the prosthesis.

Interim Denture

(Temporary RPD) Used for a short period to fulfill aesthetics, mastication or convenience until a more definite form of treatment can be rendered.

Transitional Denture

(Temporary RPD) May be used when loss of additional teeth is inevitable but immediate extraction is not advisable or desirable.

Treatment Denture

(Temporary RPD) It is used as a carrier for treatment material. It is used when the soft tissues have been abused by ill-fitting prosthetic devices.

Yes

Can artificial teeth be added to the transitional denture as when the natural teeth are extracted?

Yes

Can most patients function with a shortened dental arch (SDA)?

Fixed Partial Denture (FPD)

Requires abutments at opposite ends of edentulous space, more expensive than RPD, must grind down abutments, flexes and can fail if too long.

Implant Supported Prosthesis

Most costly treatment, closest replacement to natural dentition, less costly over long term.

Complete Denture

Treatment if there are few teeth left, with poor prognosis.

2 - 4

RPD is generally preferred when more than _ posterior teeth or _ anterior teeth are missing.

Canine

RPD is generally preferred if the ______ & two of its adjacent teeth are missing.

Distal

RPD is generally preferred when there is no ______ abutment tooth.

Edentulous

RPD is generally preferred if there’s a presence of multiple __________ spaces.

Tipped

RPD is generally preferred if the teeth adjacent to edentulous spaces are ______, they cannot be used as an abutment for a fixed prosthesis.

Weakened

RPD is generally preferred if periodontally _________ teeth are present near the edentulous spaces.

Short

RPD is generally preferred for teeth with _____ clinical crowns.
