Effect of Ethyl Alcohol Wet Bonding on Shear Bond Strength in Orthodontic Brackets - An Study.

Aim: To evaluate the effect of ethyl alcohol wet bonding on the shear bond strength of orthodontic brackets.

Materials And Methods: 90 premolar teeth were collected and divided into 6 groups - conventional dry, conventional wet, MIP dry, MIP wet, ethanol dry, and ethanol wet. The teeth were bonded as per the requirements for each group.

Evaluation and comparison of stresses and displacements generated by four different types of asymmetric maxillary expansion appliances in true unilateral crossbite using finite element method.

Introduction: True unilateral posterior crossbite can be efficiently treated by using asymmetric expansion appliances that essentially exert unilateral expansion forces thereby minimizing iatrogenic overexpansion of the normal pretreatment side.

Aim: To evaluate and compare the stresses and displacements generated by four different types of asymmetric maxillary expansion appliances in true unilateral crossbite using the finite element method.

Materials And Methods: A CBCT image of the skull was obtained from a 12-year-old female patient with a true unilateral posterior crossbite on the right side, for the FEM study.
