Chapter 30 - Care of Prosthesis (Vocabulary Flashcards)

Vocabulary flashcards covering key terms from Chapter 30: Care of Prosthesis.

Fixed partial denture (FPD)

A non-removable prosthesis that attaches to natural teeth or implants to replace missing teeth.

Natural tooth–supported fixed partial denture

An FPD anchored to existing natural teeth (abutments) to support the prosthesis.

Implant-supported fixed partial denture

An FPD anchored to dental implants rather than natural teeth.

Cantilever dental bridge

A bridge that uses a single anchor tooth; not advised for posterior areas due to excessive stress.

Maryland bonded bridge

A conservative resin-bonded bridge using a metal or porcelain framework bonded to backs of adjacent teeth; avoids tooth preparation but may cause discoloration.

Implant-supported bridge

A bridge anchored by dental implants; does not require modification of adjacent teeth and can span large gaps.

Removable Partial Denture (RPD)

A removable prosthesis that replaces one or more teeth; rests on mucosa and is supported by a metal framework with clasps.

RPD major connector

The primary structural element that connects RPD components across the dental arch.

RPD cingulum rest

A rest located on the cingulum of a tooth to provide vertical support for an RPD.

RPD occlusal rest

A rest placed on occlusal surfaces to stabilize the RPD.

RPD retainer (clasp)

The component that grasps an abutment tooth to retain the denture.

RPD denture base

The pink acrylic base that rests on mucosa and supports the denture teeth.

RPD denture teeth

Artificial teeth attached to the denture base.

Complete denture

A removable prosthesis that replaces all teeth in an arch.

Complete denture base

The pink acrylic that forms the base and rests on the mucosa.

Impression surface (complete denture)

The inner surface of a complete denture that contacts the oral tissues during fabrication.

Occlusal surface (complete denture)

The biting/chewing surface of the denture teeth.

Complete overdenture

A complete denture supported by retained natural teeth roots or implants; also called tooth-supported or hybrid denture.

Root-supported overdenture

An overdenture supported by natural tooth roots.

Implant-supported overdenture

An overdenture that is supported by dental implants.

Overdenture purpose

To preserve bone, improve retention and stability, distribute occlusal loads, and enhance proprioception.

Obturator

A maxillofacial prosthesis used to close or maintain the integrity of oral–nasal compartments after defects.

Denture marking

A system for marking dentures to aid identification; not universal but required in some jurisdictions.

Denture stomatitis

Candida-caused inflammation of oral tissues under a denture; treated with antifungals and/or chlorhexidine.

Traumatic ulcer

Denture-induced irritation lesion on oral mucosa from denture rubbing.

Angular cheilitis

Cracking and irritation at the corners of the mouth, often related to nutritional deficiencies or denture issues.

Epulis fissuratum

A painless, tumor-like growth on the gingiva/alveolar mucosa from chronic denture irritation.

Peri-implant mucositis

Reversible inflammation of the peri-implant mucosa without bone loss.

Peri-implantitis

Inflammation around an implant with progressive loss of supporting bone; may require non-surgical and surgical treatment.

Probing around implants

Probing around implants is more uncomfortable; plastic probes are used to minimize damage and improve accuracy.

Cleaning implants

Use a soft-bristled toothbrush and low-abrasive toothpaste; avoid ultrasonic tips on implants; titanium is biocompatible.

Denture marking (summary)

Identification markers on dentures; aids forensic and clinical identification.
