A Novel Double Arrowhead Auxetic Dental Splint for Avulsed Tooth Reimplantation

The proposed superelastic NiTi alloy-based DUA auxetic splint with 0.7-mm arm-width reduces tooth mobility and stresses without exceeding biological limits. This will facilitate the reimplantation of the avulsed tooth, ensuring healing of the PDL and allowing physiological tooth mobility for ossification of the alveolar bone around the tooth socket. This will inhibit further complication of the affected tooth such as hyalinization of PDL, root resorption, or tooth ankylosis.
