Conical crowns

Mostly the dentist prepares the support dies tangentionally.

You can use a conometer which has a certain amount of “room to move” between 0° and 12°.

From an aesthetic point of view, the laboratory technique starts in a similar fashion to the telescopic technique starting with surveying in the anterior area.

 Surveying with a wax-scraper 2° shows a disadvantageous path of insertion of premolar 25.

 In order to decrease the undercut in the distal area, you can work with instruments calibrated to an angle of 6°.

 All conical crowns are surveyed with a 6° angle.
