Removable partial denture | EPFL Graph Search

A removable partial denture (RPD) is a denture for a partially edentulous patient who desires to have replacement teeth for functional or aesthetic reasons and who cannot have a bridge (a fixed partial denture) for any reason, such as a lack of required teeth to serve as support for a bridge (i.e. distal abutments) or financial limitations. This type of prosthesis is referred to as a removable partial denture because patients can remove and reinsert it when required without professional help. Conversely, a "fixed" prosthesis can and should be removed only by a dental professional. The aim of an RPD is to restore masticatory function, speech, appearance and other anatomical features. RPD may be used when there is a lack of required teeth to serve as support for a bridge (i.e. distal abutments) or financial limitations. A single-tooth RPD known as a "flipper tooth" may be used temporarily after a tooth is extracted, during the several months it takes to complete the placement of a dental implant and crown. Advantages of using RPD include: Reduced encroachment on existing teeth Replacement of a greater number of missing teeth Easily removed for cleaning and hygiene maintenace Fairly simple to fix/replace the prosthesis if damaged Modifications can be made to the prosthesis in some cases following additional tooth loss Disadvantages of using RPD include: Limited stability whilst in function Significant coverage even in cases where few teeth require replacement in order to maximise retention Visible components depending on teeth needing replacement Potential risk to the health of remaining teeth due to plaque accumulation or trauma The patient's oral condition is categorized based on the remaining dentition in a classification first proposed by Dr. Edward Kennedy in 1925. His classification consisted of four general outlines for partially edentulous arches that can present within a patient, which then could be treated with an RPD. When there is an edentulous space that is outside of the four classifications, it is termed a modification space.

Recognizing distant faces

Lukas Vogelsang, Marin Vogelsang

As an 'early alerting' sense, one of the primary tasks for the human visual system is to recognize distant objects. In the specific context of facial identification, this ecologically important task has received surprisingly little attention. Most studies ...

Improving filling level classification with adversarial training

Pascal Frossard, Andrea Cavallaro, Apostolos Modas

We investigate the problem of classifying — from a single image — the level of content in a cup or a drinking glass. This problem is made challenging by several ambiguities caused by transparencies, shape variations and partial occlusions, and by the avail ...

Scaffold requirements for periodontal regeneration with enamel matrix derivative proteins

John Christopher Plummer, Laurent Mirko Dejace, Matteo Gregorio Modesto Marascio, Peter Fischer, Alessandra Apicella

Periodontitis affects the attachment of natural teeth, and infection or inflammation associated with periodontitis may affect peri-implant tissues. Enamel matrix derivative (EMD) proteins provide stimulation for self-regeneration of the damaged tissue when ...
