Used after an immediate extraction in which a patient requires stabilization and function during the healing phase of therapy. The resin removable partial denture also is designed to restore appearance until a definitive prosthesis can be fabricated
- 4. Interim removable partial denture with anterior prosthetic teeth- nos. 9 &10. Teeth on the cast have been designated for removal prior to fabrication of the immediate transitional RPD. The wax - up showing replacement of teeth nos. 23 – 26 on the immediate transitional RPD. Interim RPD, occlusal view shows wire clasps for retention on bilateral second premolars.
