Outcome 5 - Fixed Prosthodontics Flashcards
Define Fixed Prosthesis
The prosthesis is permanently cemented into place and cannot be removed by the patient
Indications for Dental Prosthesis
When there is not enough naturual tooth structure remaining to retiain a new restoration - more coverage with a dental prosthesis may be advised. This can also occur as a result of extensive decay or the loss of tooth structure through disease/trauma
How treatment plan for an indirect restoration is determined?
-Patient History
-full mouth radiographs/specific area radiographs
-intraoral examination
-diagnostic models
-diagnostic models mounted on an articulator
-face bow records
What are indirect restorations?
Unlike restorative restorations such as amalgam or composite, they are not placed directly into the mouth but are made indirectly outsode of the mouth then “fixed” or cemented into place in the mouth permanently
What can restorations be fabricated from?
Gold, precious metal alloys, porcelain, ceramic or combinations of both
What are Inlays?
Restorations resemble class II not involving dental cusps
What are Onlays?
Restoratios involving dental cusps
What are veneers?
Made from porcelain or other ceramic. They are fabricated by technicians in a dental lab and are bonded to the facial surface of prepared anterior teeth by the dental team. These veneers are very aesthetic as porcelain has a more natural appearance and reflects light in much the same way as enamel.
What is a Crown?
A Crown is an indirect restoration that covers all or almost all of the anatomic portion of the tooth.
What is a full crown?
Covers the entire anatomic portion of the tooth
What is a 3/4 Crown?
Usually leave sone surface intact. This surface is often the labial or facial surface with the Crown covering the lingual
What is a bridge?
A bridge is a fixed prosthetic replacement for one or two missing adjacent teeth where there are strong supporting teeth on each side of the gap. The replacement teeth are called pontic and are connected to full crowns on either side of the gap, called abutments.
What are Implant Assisted Crowns & Bridges?
Dental implant is used when natural tooth has been lost. Dental implant is an artificial anchor (post like) that is surgically placed into the bone. Dental implant act as the “root of the tooth” Dental crown or bridge is added to aid intra-oral function. Dental implants are used in fixed and removable prosthetics.(removable prosthetics s will be discussed next semester)
What are Computer Assisted Prosthetics?
Computer assisted restorations use an in-office ceramic restoration system. These systems are often referred to as CAD/CAM which means Computer Assisted Design or Manufacturing. Advantages of using these machines include: one visit procedure, no impressions required, no temporary restoration required, and no outside laboratory costs.
What is a CEREC machine?
uses computer imaging to custom fabricate a ceramic inlay, onlay or crown in the office, within approximately 90 minutes.
