The bond strength of mesh-base and metal-base brackets to human enamel was investigated for different adhesive systems. The bond strengths were determined by means of tension, shear, and torsion tests. The data were statistically analyzed and the following conclusions were drawn: 1. An adhesive system (bracket base and adhesive) cannot be selected on the(More)
Hardness of both the top and bottom surfaces were determined for five different composite resins varying the thickness and exposure time to light. Specimens of the five different composite resins (Durafill®, Visio-Dispers ®, Prisma-Fil®, Estilux®, and Visio-Fil ®) were prepared in brass rings with thicknesses of 1.5, 2.0, and 2.5 ram. A Barcol Hardness(More)
A three-dimensional photoelastic model was reproduced from a human skull. The insertions of the superficial and deep portions of the masseter muscle and the temporalis fascia were simulated with leather bonded to the appropriate areas. The following loading conditions were employed: (1) bilateral loading of the masseter muscle; and (2) bilateral loading of(More)
A three-dimensional photoelastic model was reproduced from a human skull. The insertions of the superficial and deep portions of the masseter muscle, the temporalis muscle, the medial pterygoid muscle and the temporalis fascia were simulated with leather bonded to the appropriate areas. The following loading conditions were employed: (i) all three muscles(More)
