Intro + Treatment Planning Flashcards
art or science of replacing absent body parts
Prosthetics
any artificial part
Prosthesis
branch of dentistry that pertains to the replacement of missing teeth and oral tissues
Prosthodontics
What are the three Prosthodontics Divisions?
Fixed
Removable
Maxillofacial
What are the two branches of removable prosthodontics
complete
partial
artificial replacement of 1 or more teeth and/or associated structures
Dental Prosthesis
– Prosthesis replacing teeth in partially dentate arch.
– Not designed to be removed by patient.
• Fixed Partial Denture (FPD):
– Prosthesis replacing teeth in partially dentate arch.
– Designed to be removed by patient.
• Removable Partial Denture (RPD):
– Tooth used to support prosthesis
Abutment
– Residual bone & soft tissue covering that
remains after tooth loss.
– Part of support for certain types of RPDs
• Residual (edentulous) ridge:
– Maxillomandibular relationship in which the
condyles articulate with the thinnest avascular portion of their respective disks with the complex in the anterior-superior position against the slope of the articular eminence.
– Position independent of tooth contact.
– Position restricted to purely rotational motion.
Centric Relation
– Position with complete intercuspation of
opposing teeth.
– Independent of condylar position
– Previously called Centric (Habitual)
Occlusion
Maximal Intercuspal Position

accuracy not implied.
Model
An accurate positive reproduction of the
maxillary or mandibular arch.
Cast
Cast for the purpose of
diagnosis & treatment planning.
Diagnostic cast
Replica of teeth, residual ridges, & other parts of the dental arch used to fabricate dental restoration or prosthesis.
Master Cast
– RPD that depends entirely
on natural teeth for support
Tooth-supported RPD
– Extension base RPD
– RPD supported and retained by teeth at only one end.
– Denture base is supported by teeth & the residual ridge
Tooth-tissue Supported RPD
• Edentulous area(s) too long or numerous for a fixed prosthesis
• Need to restore lost soft and hard
alveolar tissue, especially in the anterior region****
• Reduced periodontal support of remaining teeth
• Need to distribute masticatory stresses across the dental arch: cross-arch stabilization
• No posterior abutment tooth
• Immediate replacement of teeth
• Attitude & desires of patient (economic considerations)
Indications for RPDs
- Removable, not considered ‘part’ of patient
- May be lost or broken
- Clasps may be visible, less esthetic
- May dislodge during function
- May trap food while eating
Disadvantages of RPDs
