Sureical temdate fabrication for immediate dentures

John B. Farmer, D.M.D.* Fort Hood, Tex.

T he use of a clear surgical template’ for immediate complete or temporary removable partial denture con- struction is of considerable benefit, especially if the alveolar contour is to be altered significantly. Proper contour of a master cast to anticipated bone loss; reduction of bony prominences, tori, or tuberosities; or reattachment of the mucogingival junction at a desired depth may be necessary in immediate denture construc- tion.*xl A surgical template is desirable when these procedures are to be accomplished.

The following modification of a technique previous- ly described for construction of custom trays has an application for construction of surgical templates.’ It provides an accurate reproduction of the tissue surface of an immediate complete or temporary removable partial denture.

TECHNIQUE

1. Completely contour, finish, and polish the pro- cessed immediate complete or temporary removable partial denture.

2. Make an accurate irreversible hydrocolloid impression of the tissue surface of the denture to include the entire flange. A rim lock tray serves as the matrix for the impression material.

3. Mix clear autopolymerizing orthodontic acrylic resin to a thin consistency (10 ml to 30 gm powder) (Unitek Corp., Walther Acrylics, Monrovia, Calif.).

4. Using a mechanical vibrator, pour the clear resin into the impression of the denture and place in a water bath at 30 psi pressure for 20 minutes.

5. Remove the cured template from the impression, remove the flash from the borders, and finish. Any excess acrylic resin is contoured to proper form and thickness with an acrylic resin bur. Total working time is less than 1 hour.

The resultant template is a clear, dense, accurate reproduction of the internal surface of the finished
