Gingival retractation

Any gingival retraction method can be used when taking an impression with Apol Classe, i.e.: single cord method, double cord method, or even gingivectomy using an electrosurgery unit, when the quality of the gingiva allows it.

However, whatever method is used, the aim remains the same: opening up the gum margin is essential in order to reproduce the cervical margins accurately.

The cord should not be completely buried in the sulcus. It should remain visible along the whole length of the preparation.

The cords sometimes have an annoying tendency to lift. Replacing the provisional crown on the preparation will keep the cords in the sulcus for as long as required.
