Polycarbonate crowns are extremely attrition-proof. They may be adapted easily to the gingival line by means of a cutter. The crowns protect dentine against the influence of high and low temperatures, as well as protect a prepared tooth until a complete crown restoration is made. Polycarbonate crowns may be used in making temporary (provisional) bridges.

How to use :

1. After removing the enamel, remove the smear layer from the dentine. Disinfect the whole surface up to the line of cervical zone after preparation. Block all dentinal tubules with appropriate preparation.
2. Choose appropriate crown size, match the cervical part by cutting it, so that it reaches only the gingival line (PLEASE NOTE! No subgingival nor supragingival matching!), and then polish the sharp edges of the crown. The polycarbonate crown should be disinfected with e.g. ethanol.
3. Fill the polycarbonate crown with cement in a shade matching the colour to the colour of the adjacent teeth.
4. Place the crown filled with temporary cement in required position and hold it until the material is hardened – remove the excess material.
