ExperTemp Temporary Crown Placement Guide

Quick answer

Place ExperTemp temporary crown and bridge material in four clear steps to achieve strong, esthetic provisional restorations with easy handling and excellent polishability.

Step-by-step placement guide

1. Prepare the tooth and select the matrix: Isolate the prepared tooth with a rubber dam or cotton rolls and retraction cord. Choose a preformed crown form or a vacuum-formed matrix from the diagnostic wax-up. Ensure the matrix fits passively without binding on adjacent teeth. If the matrix is too tight, trim the gingival margin or use a slightly larger size to avoid trapping excess material under the gingiva.
2. Mix and load the ExperTemp material: Dispense equal lengths of base and catalyst onto a mixing pad. Mix for 20-30 seconds until a uniform color is achieved. Load the matrix from the occlusal aspect, slightly overfilling the most retentive areas. Avoid trapping air bubbles by pressing the material into the matrix with a spatula. A common mistake is underfilling the matrix, which leads to voids at the margin. Overfill slightly and trim excess after setting.
3. Seat and hold the matrix: Place the loaded matrix onto the prepared tooth and seat it with gentle finger pressure. Hold steadily for 3-4 minutes (or follow the manufacturer's working time for the specific shade). During setting, wipe away excess material that flows onto adjacent teeth using a microbrush. Do not release pressure early; premature removal can distort the temporary or create open margins. Use a timer to ensure consistent setting.
4. Remove, trim, and polish: After the material has set, gently remove the matrix. Use a sharp explorer to lift the temporary from the tooth. Trim excess with a carbide bur or diamond finishing bur at low speed. Polish the temporary using silicone polishers or a pumice slurry to achieve a smooth, esthetic surface. Check marginal fit with an explorer. If the margin is open or overextended, adjust with a finishing bur and re-polish. Do not cement a temporary with a defective margin.
