Abstract
An obturation apparatus for prepared root canals incorporates the functionality of an endodontic spreader but with a circular disk located at a fixed distance from a distal tip of the apparatus and regulates the length of bioceramic putty inserted into the prepared root canal. The instrument comes in various sizes to cater to prepared root canals of differing dimensions such that the apparatus must be prefit before the application of the bioceramic putty to the apparatus tip before extending the bioceramic putty to the distal side of the circular disk. The apparatus is then inserted to a desired depth with application of apical pressure leaving the bioceramic putty in place as an apical plug when the apparatus is removed.
Claims1
A method of performing obturations in a prepared root canal of a patient, the method comprising:
- selecting an endodontic spreader sized to fit the prepared root canal of the patient, wherein the endodontic spreader comprises:
- a handle portion having a distal end and a proximal end;
- a shaft or stylus having a distal end and a proximal end, the proximal end of the shaft or stylus being connected to the proximal end of the handle portion, and the shaft or stylus having a tapered portion that terminates in a tip at the proximal end of the shaft or stylus;
- and
- a circular disk situated 4 mm from the tip at the proximal end of the shaft or stylus wherein the circular disk is perforated by a plurality of holes along a periphery of the circular disk, wherein the tip is configured to hold a portion of bioceramic putty;
- placing the portion of bioceramic putty on the tip at the proximal end of the shaft or stylus of the selected endodontic spreader;
- proximally extending the portion of the bioceramic putty on the tip at the distal end of the shaft or stylus of the selected endodontic spreader towards a distal end of the circular disk such that the extended portion of the bioceramic putty is manipulated to stretch along the 4 mm distance between the circular disk and the tip of the shaft or stylus of the selected endodontic spreader;
- inserting the selected endodontic spreader into the prepared root canal of the patient such that a desired depth of the prepared root canal is reached;
- applying apical pressure to the selected endodontic spreader leaving the portion of the bioceramic putty as an apical plug;
- preventing the portion of the bioceramic putty from rising beyond a desired height of the prepared root canal by levelling off any extra putty protruding through the plurality of holes of the circular disk to be an even surface such that the portion of the bioceramic putty remains shaped as a plug at the apical end of the prepared root canal;
- and
- removing the endodontic spreader from the prepared root canal of the patient.
