Bond Strength of Orthodontic Brackets to Temporary Crowns: In Vitro Effects of Surface Treatment.

Background: The number of patients seeking orthodontic treatment has been consistently increasing. During orthodontic treatment, it is recommended to place the provisional restoration and to delay the final restoration until completion of orthodontic treatment. Recurrent bracket debonding necessitates orthodontists to prepare the bonding area with special measures.

Chemo-Mechanical Approach to Improve Repair Bond Strength of Denture Teeth.

Background: Detachment of acrylic teeth from denture base material is a common complication in dentistry which accounts for 26-30% of repair cases. This study aimed to evaluate the effect of alumina-blasting, silane coupling agent, and thermal cycling on the shear bond strength of repaired teeth to denture base.

Materials And Methods: Specimens (140) of repaired teeth to denture bases were fabricated and divided into 14 groups: 7 groups before thermal cycling and 7 groups after thermal cycling ( = 10).
