Effective preparation of sulcus for the impression
This is a blunt therma-cut drill that is primarily designed to remove thermophilic carriers for endodontics.
When you put it in the turbine without cooling, it cuts the gingiva beautifully.
The advantage is that only vestibular anesthesia is sufficient. No palatal anesthesia is required. It does not hurt the patient at all!
If you use high-frequency current - Kauter, you must always inject palatal anesthesia, which is a loss of 3-5 minutes.
The huge advantage of this method is that it heals perfectly. The gingiva will return to their original level within a week.
