3. Interim Partial Denture Definition:
Removable prosthesis, designed to enhance esthetics, stabilization and /or function for a limited period of time, after which it is to be replaced by a definitive prosthesis.
4. Types There are three (3) basic types of Temporary removable partial dentures:
Interim
Transitional
Treatment partial dentures based upon their individual uses
5. Indications When age, health, or lack of time precludes more definitive treatment
Young patients who have lost one or more teeth as a result of trauma
When orthodontic bands and wires are difficult to place due to the short length of the teeth (space-maintenance)
Elderly patients whose health contraindicates the lengthy and physically trying appointments of a definitive or permanent prosthesis
6. Indications Interim partial dentures as part of the total
treatment:
The sake of appearance
Maintenance of a space
Reestablishing occlusal relationships
Conditioning teeth and residual ridges
Conditioning the patient for wearing a prosthesis
7. Indications Esthetics
Space Maintenance
Occlusal Function
8. Complications
9. Clinical Procedures Maxillary and Mandibular alginate impressions (after teeth cleaned)
Cast fabrication using a Type III or IV dental stone
If the casts can be unmistakably articulated, a jaw record will not be necessary (maximum intercuspation)
10. Clinical Procedures If a jaw record is needed, a record base must be fabricated
Select the tooth shade
Shapes and sizes of the artificial teeth can be determined based upon information from the master cast
11. Laboratory ProceduresFlipper fabrication Wax Method:
Most of the removable partial dentures have acrylic resin denture bases and acrylic resin artificial teeth
Acrylic resin base that extends into interproximal areas provide retention for the prosthesis
Ball claps consist of a ball of solder on the end of a piece of wrought wire
12. Ball clasp
13. Measuring the ball clasp
14. Bend the ball clasp
15. Ball clasp cross the marginal ridges and engages an interproximalundercut on the facial surfaces
17. The remainder of the clasp is coiled and bent
19. The coiled portion must be slightly out of contact with the palatal surface of the cast To allow acrylic resin flows completely around the wrought wire and lock it in place
20. The wrought-wire clasps are shaped and affixed to the cast using sticky wax Selection of the denture teeth
22. Baseplate wax is softened and countered to fit the palatal portion of the cast
23. The wax extends into the interproximal areas to provide retention to the flipper
25. Finish and Polish
