TRANSDENTAL IMPLANTATION PROCEDURE Russian patent published in 2014 - IPC A61C8/00 

FIELD: medicine.

SUBSTANCE: invention is applicable for restoring biomechanical characteristics of the teeth with resected and amputated roots, and orthopedic rehabilitation thereof. A crown portion and a tooth canal orifice are prepared for a dental inlay core. The root canal is prepared along the whole length, and a transfer pin is adjusted. A silicone impression compound is introduced into the canal, and reinforced with the adjusted transfer pin. An impression is prepared with the pin fixed therein. A cast is prepared. A supraradicular portion of the transdental implant is shaped from wax on the prepared model above the pin fixed in the cast. A circular chamfer inclined 135 degrees is formed on the cast stump along the whole perimeter. The prepared structure is prepared with an anti-reflective powder. An optical impression to be digitised is prepared. A diameter of the intraradicular portion is modelled providing a circular gap of 100 mc between the implant and canal walls. An end of the intraradicular portion of the transdental implant is shaped as a truncated cone with rough and corrugated surface in the form of a threading with a rounded end face. A virtual model of the transdental implant is milled from a titanium block. The root is resected or amputated under local anaesthesia. Glass-ionomer cement is introduced into the root canal on a canal filler, and the transdental implant is fixed. An intraoperative defect is filled with a bone-replacement preparation. The wound is closed completely. A temporary fixed orthopaedic denture is made and postoperatively fixed on the supraradicular portion of the transdental implant.

EFFECT: method enables providing more effective orthopaedic dental rehabilitation of the teeth with resected and amputated roots reinforced with the transdental implants.
