The use of orthodontic treatments in patients with temporary prostheses has been increasing, the purpose of this in vitro research is to measure the adhesive bond strength between orthodontic resin and acrylic surfaces by applying different procedures. Objective. To compare the adhesive bonding strength between orthodontic resin and acrylic surfaces under different application protocols. Methodology. Transversal, experimental, prospective study. In vitro with acrylic provisions, was carried out in the laboratory of the Faculty of Dentistry of the Universidad Veracruzana region of Veracruz. In the period of February-June of the year 2019. The sample was conformed by two control groups of specimens and four experimental ones, each group conformed by 20 specimens, in total 120 provisional ones were made in acrylic Nic Tone of quick self-cure. The tests performed by the ULTRATESTER machine were expressed in MPa. Later, the data obtained were processed in Excel tables (version) for statistical processing in SPSS version 24. Contribution. When comparing the pre-cutting protocol of acrylic surfaces with fine diamond bur and the protocol without pre-cutting, no statistically significant differences were found, therefore, this step could be omitted in clinical practice.

Adhesive Bond Strength

Adhesive bonding is one of many materials connecting methods. In the last ten years periods the bonding technology noted a boom almost in all industrial branches. The use of bonding technology in the engineering and repairing industry brings considerable savings. Saving in costs, in critical metallic materials and in time are reached and the decrease of the joint weight, too. Therefore the bonding technology pertains to the modern jointing methods even though it is a very old technique. The adhesive bonding technology is influenced by a number of factors which affect the adhesive bond strength. Correcting coefficients have to be considered in construction calculations too. The correcting coefficients correct the strength deviations caused by particular factors. In the paper there are published laboratory experiments results.

Adhesive Bond Strength

Abstract Norway spruce wood specimens covering a wide density range, including density samples between 300 kg m-3 (low density wood) and 750 kg m-3 (high-density compression wood), were joined at end grain surfaces and tested in tension perpendicular to the bonded surface to estimate the effect of mechanical interlocking on the adhesive bond strength. It was hypothesised that the higher the density of the specimens the lower will be the mechanical interlocking of the adhesive joints due to a reduced penetration of the adhesive into the cell cavities. An increase of tensile strength was observed with increasing density. These results demonstrate that in the specific case investigated here the cross-sectional cell wall area available for adhesive bonding, which correlates with density, is probably more important than mechanical interlocking.

In recent years, there has been an influx of multi-material components into the manufacturing field. For a large number of cases where joining of non-metallic parts are involved, adhesive bonding is given preference over traditional joining processes. One of the prominent methods of enhancement of adhesive bond strength is by use of additives on the adhesive. Adhesive joints are commonly used in load-bearing structures. The loading is primarily in the shear mode. Hence, the shear modulus of the adhesive is a primary index of the adhesive bond-strength. In this work, a mathematical model for adhesively bonded single strap butt joint is developed and an inverse method to calculate the effective shear moduli of graphite/epoxy mixtures of different ratios is presented.
