Tooth Supported
What Kennedy Classification System?
-Supported by teeth @ only one end,
-Distal Extension RPD’s
-Unbounded or Free End Cases
Tooth Tissue Supported
What Characteristics and Biomechanics?
- To Resist displacement by
FUNCTIONAL HORIZONTAL OR ROTATIONAL STRESSES?
Stability
What Characteristics and Biomechanics?
- Resistance to forces, directed TOWARD THE BASAL TISSUE OR UNDERLYING STRUCTURE
Support
What Characteristics and Biomechanics?

Retention
What Characteristics and Biomechanics?
-resist the forces of DISLODGEMENT ALONG THE PATH OF PLACEMENT
Retention
What Characteristics and Biomechanics?
Quality of Clasp assembly,
that counteracts
(Lateral Displacement) of the Abutment when the Retentive Terminus passes over the height of contour?
Reciprocation
What Characteristics and Biomechanics?
Prevents Movement of an Abutment, AWAY from the associated clasp assembly
Encirclement
What Characteristics and Biomechanics?
Resistance to ( Horizontal Component of Masticatory force;
-stabilizing element located in a NON UNDERCUT AREA
Bracing
What Characteristics and Biomechanics?
Providing regulation or direction to movement during insertion and removal
- contact of the rigid parts parallel to the path of isertion
Guidance
What Impression Philospohies?
The impression is taken when the patient is on “RESTING STATE”
- NO tissue displacement
Mucostatic /Minimal Pressure Impression
What Impression Philosophies?
Directing the force to the MOST CAPABLE WITHSTANDING FORCE
- Done by Beading the Diagnostic Cast or altering the impression tray?
Selective Pressure
What Impression Philosophies?
Directing the force to the MOST CAPABLE WITHSTANDING FORCE
- Done by Beading the Diagnostic Cast or altering the impression tray?
Selective Pressure
What Impression Philosophies?
Load or Pressure is applied on the ridge as the impression is taken
Functional Impression
What Impression Philosophies?
A Modification of the “Functional Impression Technique”
-A Negative Likeness of a
Portion of Edentolous Denture bearing area are made
Altered Cast Technique
A Method of Impression commonly used for THE MANDIBULAR DISTAL EXTENSION,
partially edentolous arch due to greater variation in tissue mobility and displaceability?
