The 1/4 Perio Elevator with Curved Blade 3mm Straight Edge is a periodontal surgical instrument designed for precise tissue elevation and manipulation. The 1/4 size indicates the narrow width of the blade, making it ideal for fine, controlled work in delicate gum tissue areas. The curved blade allows for better access to deeper or more curved areas within the periodontal space, while the 3mm straight edge provides a clean and accurate cutting or lifting surface.
