classification of partial removable dentures Flashcards
why is it important to classify different partial removable denture types
- formulate a good treatment plan
- anticipate difficulties common to occur for a particular design
- communicate with professionals
- to design the denture according to occlusal load usually expected for a particular group
what is Kennedy classification I
bilateral edentulous area located posterior to the remaining natural teeth
Kennedy class II
a unilateral edentulous area located posterior to the remaining natural teeth
Kennedy class III
a unilateral edentulous area with natural teeth remaining both anterior and posterior to it
Kennedy class IV
a single, but bilateral (crossing the midline) edentulous area located anterior to the remaining teeth
Kennedy class I
Kennedy class II
Kennedy class III
Kennedy class IV
what are the advantages of the Kennedy classification
permits immediate visualisation of the edentulous arch
permits a logical approach to the problems of design
makes possible the application of sound principles of partial denture design
what is the bailyn classification
based on whether the prosthesis is tooth borne, tissue borne, or a combination of the two that is based on support
all removable partial dentures are divided into A and P
what is A bailyn classification
anterior restorations where there are saddle areas anterior to the first bicuspid
what is B bailyn classification
posterior restoration saddle area posterior to the canine
what is class I of bailyn
bounded saddle where there is no more than three teeth missing
what is class II of bailyn
free end saddle where there is no distal abutment
