Abstract

The invention provides a boning round bur for dental crown lengthening. According to the boning round bur, an annular boss portion is arranged on the upper part of a spherical bur needle, and different heights of a scale area for determining the boning amount are formed at the lower end surface and the upper end surface of the annular boss portion, so that the boning round bur can facilitate operation of periodontal clinicians, and avoid accidental injury to tooth tissue, thereby better serving patients with periodontal surgery.

Description

technical field [0001] The present invention relates to a dental crown extension surgical instrument, in particular to a dental crown extension and bone removal drill. An annular boss is arranged on the upper part of a spherical drill, and the lower end surface and the upper end surface of the annular boss are formed into different The height line of the scale area used to judge the amount of bone removal can be beneficial to the periodontal clinician's operation, avoid accidental injury to the tooth tissue, and thus better serve the periodontal surgery patients. Background technique [0002] Crown lengthening is a routine oral procedure, generally classified as periodontal surgery, aimed at improving the patient's aesthetics (gummy smile) or in preparation for restorative treatment. At present, the instruments used for osteotomy and osteoplasty in crown lengthening surgery are relatively simple, and generally only different types of ball drills are used (different types of ...
