Title: Endodontic instrument for drilling root canals
Inventor: BREGUET OLIVIER
IPC: A61C5/00
Filed: 2015-07-06
Abstract: The present invention concerns an endodontic instrument or drill-bit for preparing a tooth of a patient, in particular an instrument for cleaning the root canal that follows the natural geometry of said canal. The root canal geometry is not straight or linear, but is curved or non-uniform. The endodontic instrument is made of a shape memory material having a first static state with a substantially straight geometry to facilitate the instrument being inserted partially into the said root canal and a second dynamic state corresponding to a structured geometry, a supple flexible behaviour, in which the endodontic instrument is set rotating to clean the said root canal following its natural geometry. The instrument has a rigid tip arranged to be mounted on a rotating support and a working sector arranged to be engaged in said root canal, when the instrument is in its dynamic state, the working sector consists of a first substantially straight active segment disposed in the extension of the said rigid tip, this first active segment being prolonged by a second active segment having a free end and having a curved shape between the point where the said first active segment and a free end meet. The shape memory material is a shape memory metal alloy in which the transition from the martensitic phase to the austenitic phase occurs naturally at a body temperature between 32°C and 37°C, the instrument being in its dynamic state at this temperature.

The proximal part of the first component facing the second component is curved away from it preventing it impinging against the 2nd component during flexion of the joint assembly in use. The fixation portions provide stable anchoring of the implant assembly straight after surgery.

Abstract: FIELD: medicine. SUBSTANCE: method includes processes for manufacturing and setting bearing overhanging and bridge structures and involves mounting anterior and posterior cross-pieces made from soft composite material Alphadent hardening under being exposed to light emitted by lamp of some kind onto prepared (pretreated) artificial and anchor (anterior and posterior) teeth surface. Optionally, the cross-pieces are useable that are manufactured from some chemical composite material. To make structure of higher strength and reliability level, the cross-pieces are connected through interdental spaces between the artificial teeth and artificial and bearing teeth. The structure receives rigid properties and becomes like magazine. The interdental spaces being too narrow, they are to be widened up to 2-3 mm at the cost of artificial teeth. When needed (high loads on teeth), the posterior cross-piece is reinforced by means of heat-treated stainless steel reinforcement wire which cross-section is not greater than 3 mm. Beside that, in case both cross-pieces are set, the spaces between the teeth are filled with composite material and treated to make impression of natural teeth . The material is treated so that vertical grooves (spaces) form angle in the cross-section of these teeth which sides belong to the lateral surfaces of the mentioned teeth. The apex of the angle is to belong to the anterior wall of the posterior cross-piece. Composite layer thickness between the groove and tooth is to be at least 1 mm. EFFECT: simplified process; wide range of applications.
