What is the everStick periodontal splint?

periodic splintA relatively new technique for splinting mobile teeth is available in the everStick periodontal splint. The fibre reinforced composite periodontal splint stabilizes the mobile teeth and ensures a more comfortable chewing function for the patient. In this technique, glass fibre strands embedded into a polymer bis GMA matrix (resin) are used to reinforce the composite white filling material, which splints the mobile teeth together. The glass fibre bundles are embedded into the same matrix as is found in the composite (white filling) material and true bonding is obtained between the fibres and the composite filling material. The bond obtained between composite resins and etched enamel is the strongest bond possible in the oral cavity ( Bond strength of approximately 28 MPa). The flexural strength of the everStick fibres is as high as that of chrome cobalt cast metal but the splint has the advantage of not being completely rigid, but has a modulus of elasticity very close to that of dentine. The elasticity of the fibres may be beneficial to the healing of the supportive dental tissue. A fibre splint constructed in this way will form an reliable integrated structure which will give a potentially long term solution to the problem of mobile teeth. The fibres are transparent and unnoticeable when covered with the tooth coloured composite filling material. It is therefore possible to create an aesthetically pleasing splint on the inside of the mobile teeth.
