The provisional crown is a temporary crown that protects the tooth and restores appearance until the permanent crown can be placed. It is held in place by the use of a temporary dental cement, and is designed to function adequately for a period of 2 to 4 weeks only. If the provisional crown comes off, cement it with a paste mixture of flour and water, or a denture adhesive paste.
No preparation is needed for Hi-Tech Temps. However, existing preparation of any type can be used.
For best results, reline with a methyl methacrylate acrylic reline material (Jet, Lang; Coldpac, Motloid; Palavit 55, Heraeus Kulzer). Other reline materials should be avoided. However, if used, mechanical undercuts must be cut into the abutment shells for better retention and reline material.
Follow these steps:
- Try in restorations. If any adjustment is needed to seat the restoration, use a low-speed carbide or composite finishing bur. Rinse with water and dry completely.
- Apply a thin layer of Vaseline to the outer surface of restoration to prevent excess reline material from sticking. Reline Hi-Tech Temps by blocking out any undercuts on the preparations.
- Mix acrylic per manufacturer's instructions and fill abutment between 1/2-3/4 full. After the surface of the acrylic material loses its shine, carefully place the Hi-Tech Temps over the preparations. Do not allow the reline material to fully cure on the preparations due to heat generation, which may cause injury to the pulp. Gently work the Hi-Tech Temps on and off the preps, allowing them to bench cure.
- Trim away any flash or excess acrylic using a plastic grinding disc. Hi-Tech Temps can be polished with pumice and polishing paste or resealed with a light cured glaze, such as Palaseal (Heraeus Kulzer). Cement Hi-Tech Temps using a non-eugeno.
