Titanium Grade 4 (G4) is the most commonly used material for dental implants due to its excellent biocompatibility and mechanical properties. However, titanium require a rough surface that can increase biomechanical potential of implant–bone contact affect protein adsorption speed. In this work, effect sandblasting Ti G4 on long-term corrosion resistance in artificial saliva pH = 7.4 at 37 °C w...

objective: repair of an indirect restoration is usually preferred over its replacement. this study aimed to evaluate the effect of silane in different surface preparation techniques on the bond strength of direct to indirect composite resin.   methods: for this in vitro experimental study, 48 indirect composite cubes were fabricated, divided into 4 groups of 12 and subjected to the following pr...

background: repair bond strength of different composite resins has been assessed in few studies. in addition, reports on the effi cacy of surface treatments are debated. therefore, this in vitro study was conducted to evaluate the effect of three surface treatments on two nanocomposites versus a microhybrid composite. materials and methods: in this experimental study, 135 composite blocks (45 s...

High quality concrete is a type of that has been given special treatment, if no materials are added, it cannot always be obtained with conventional materials. The purpose this study was to determine the best sandblasting substitution composition in producing high concrete. method used design mixture SNI method, 42 MPa. results indicate for testing compressive strength at age 28 days, highest va...

: The purpose of giving space maintainer in primary dentition is to prevent the migration adjacent teeth, thus holding dental arch for succedaneous tooth erupt. Molar band fundamental component maintainer. retention surface important ensure fixed appliance therapy. Several methods have been described improve mechanical retentive surfaces bands including sandblasting, burs, etc. Sandblasting met...

This study evaluated the influence of conventional and alternative surface treatments on wettability bond strength between polyether ether ketone (PEEK) veneering resin. PEEK samples were randomly divided into five groups: sandblasting, tribochemical silica coating, etching with 98% sulfuric acid for 5 s, 30 coating plus heated silane. One them was subjected to analysis by energy-dispersive X-r...

This work aims to reveal the effects of 3D roughness parameters sandblasted surfaces on bond strength between thermal spray coatings and substrates. The investigation was carried out surface AISI 4140, which were pretreated with automatic-sandblasting system. topography analyzed by a optical profiler. WC-12Co measured using pull-off test method. Scanning electron microscope revealed that morpho...
