The 1/4 Perio Elevator Curved Blade 6mm Straight Edge is a surgical instrument used in periodontal procedures for elevating or reflecting tissue. The 1/4 size refers to the blade width, which is narrower and suitable for fine, precise manipulation of soft tissue. The curved blade allows for better access to curved or difficult-to-reach areas, and the 6mm size provides an ideal balance for maneuvering in tighter spaces.
