THE STUDY OF THE VALUE OF TEMPORARY GUM RETRACTION IN CARRYING OUT DENTAL ORTHOPEDIC PROCEDURES RESTORATIONS

Thompson first reported on gum retraction methods in 1941, suggesting the use of moistened twine. Currently, both mechanical and chemical and combined methods are used for gum retraction. Mechanical gum retraction involves the use of unpowered retraction threads or rings, silicone caps for gum retraction and special tools such as gum elevators. Hemostatic solutions or gels are used for chemical gum retraction. For complex gum retraction, retraction filaments, impregnation rings and retraction pastes are used.
