MR&R INTRODUCTION

In order to cope with some special cases of root canal treatment, dental tools manufacturer NIC Dental has introduced the MR&R System. The MR&R System was designed and developed on the basis of two national patents. It can be used to remove broken files in root canal and deliver MTA or other biomaterials.
Root canal file breakage can occur due to factors like complex canal anatomy, improper use of files, manufacturing defects, or inadequate knowledge. Broken endodontic files can block the canal, making cleaning difficult and affecting the prognosis of the tooth. Leaving the broken endo file unaddressed can lead to discomfort and increase the risk of treatment failure.
This is where our MR&R System comes into play. It is effective in removing broken files left in the root canal, handling perforation repair in endodontics, etc. It improves the success rate of treatment and patient comfort.
