Orthodontic bonding: Finite element for standardized evaluations

This study proposes a behavioural model to describe tooth–adhesive–bracket devices, which can assess objectively and optimize the hardening of orthodontic bonds in different clinical situations.

Description
Summary:This study proposes a behavioural model to describe tooth–adhesive–bracket devices, which can assess objectively and optimize the hardening of orthodontic bonds in different clinical situations. A numerical study is carried out and the mechanical strength of the joint is assessed with regard to several parameters: the direction of the loading of the bracket/adhesive/enamel system, the value of the elasticity modulus of the dental enamel, the thickness of the joint and the position of the bracket on the vestibular side of the tooth. The results show that the mechanical strength of the joint depends on the thickness of the adhesive, the specific position of the bracket on the vestibular side and the loading mode.
