The aim of this study was to evaluate the effects of different surface preparation methods on the shear bond strength (SBS) of orthodontic metal brackets to aged nano-hybrid resin composite surfaces in vitro. A total of 100 restorative composite resin discs, 6 mm in diameter and 3 mm thick, were obtained and treated with an ageing procedure. After ageing, the samples were randomly divided as follows according to surface preparation methods: (1)Control, (2)37% phosphoric acid gel, (3)Sandblasting, (4)Diamond bur, (5)Air-flow and 20 central incisor teeth were used for the control etched group. SBS test were applied on bonded metal brackets to all samples. SBS values and residual adhesives were evaluated. Analysis of variance showed a significant difference (p<0.001) between the groups. Sandblasted group had the highest SBS value (12.85 MPa) in experimental groups. The sandblasting surface treatment is recommended as an effective method of bonding orthodontic metal brackets to nano-hybrid composite resin surfaces.

“…The use of amalgam has decreased and most patients demand composite restorations due to superior esthetics (3-5). Composite resins are extensively applied for restoration of carious teeth, pit and fissure caries, abfraction defects, diastema closure, build up of peg laterals, restoration of incisal fractures and composite veneers (6). Thus, composite restorations are frequently found in buccal surfaces of maxillary incisors as well as posterior teeth.…”

“…Mechanical methods include roughening of the composite surface with diamond bur or sandblasting. The chemical techniques include acid etching with phosphoric acid or hydrofluoric acid and application of different bonding resins (4-6,12).

BackgroundThis study aimed to assess the effect of surface preparation with sandblasting and diamond bur along with the use of three primers on shear bond strength (SBS) of metal brackets to aged composite.Material and MethodsIn this in vitro, experimental study, 60 Filtek Z250 composite discs were fabricated (10×2mm), immersed in distilled water for 24 hours and subjected to 5000 thermal cycles. They were randomly divided into two groups (n=30) of sandblasting with aluminum oxide particles for 10 seconds and surface roughening with bur. Each group was randomly divided into three subgroups (n=10) for use of Transbond XT, Assure Plus and Composite Primer. Metal brackets were bonded and the samples were stored in distilled water for 24 hours followed by 2000 thermal cycles. The SBS of brackets was measured and the adhesive remnant index (ARI) score was calculated. The data were analyzed by one-way ANOVA, t-test and Chi square test.ResultsThe difference in the mean SBS was not significant among the six subgroups. ConclusionsAll combinations of primers and surface preparation methods provided adequately high SBS between brackets and aged composite surfaces. Considering the ARI scores, surface roughening by bur is superior to sandblasting. Key words:Shear strength, composite resins, orthodontic brackets, aged composite, surface preparation.

“…The score was a 4-point scale, which was determined according to the remaining adhesive at the bracket base; 0=all adhesive left on the bracket base, 1=more than half of the adhesive left on the bracket base, 2=less than half of the adhesive left on the bracket base, and 3=no adhesive left on the bracket base. In 1990, Bishara and Trulove (39) developed a 5-point scale for ARI scores: 1=no adherence of composite on the bracket base, 2=less than 10% of composite remaining on the bracket surface, 3=more than 10% but less than 90% of composite remaining on the bracket surface, 4=more than 90% of composite remaining on the bracket surface, and 5=all composite remaining on the bracket base.In the literature on direct and indirect bonding (30,32,33,35,36), the ARI scores were usually 1 and 2 for most of the resins. This shows us that the fracture type is usually cohesive.…”

In recent years, the popularity of indirect bonding increased due to advantages such as reduction of chair time and enhancement of patient comfort. Although the indirect bonding technique has improved over the years, the literature has shown different techniques of bracket placement; furthermore, new materials were specially developed for this technique. The aim of this article is to provide a review of the literature, advantages, disadvantages, and laboratory and clinical stages of the indirect bonding technique. Keywords: Indirect bonding, bonding systems, orthodontics indirect technique INTRODUCTIONIndirect bonding was developed by Silverman and Cohen (1) in 1972 to reduce clinical time and to enhance patient comfort. In this method, they used cement for attaching brackets to the stone model, a sealant as a clinical adhesive, and thermoplastic trays for the transfer of the brackets. In 1979, Thomas (2) invented "custom composite base technique, " which is still the most widely accepted technique currently used for indirect bonding. In this technique, Thomas used a chemically-cured resin for attaching the brackets in a laboratory and a universal and a catalyst resin as the clinical adhesive. The major complication of the Thomas technique is that the polymerization of the chemical resin starts in the patient's mouth, which is problematic in terms of time. If the transfer tray was removed before the completion of polymerization, bracket failure can be seen, and if the tray was left in the mouth for too long, this can disrupt the patient comfort. To solve this problem, the Thomas technique was modified; the universal and catalyst resins were mixed outside the mouth and directly applied to the teeth and custom base (3). With the modified Thomas technique, indirect bonding achieved similar bond strength values compared with direct bonding.In the previous literature, chemically-cured resins were usually used as clinical adhesives for indirect bonding. Apart from these resins, glass ionomer cements, acrylic epoxy adhesives, and cyanoacrylates were also used (4-6).Read and O'Brien (7) used light-cured resins for indirect bonding in 1990, and with the advantages of these resins, the indirect bonding technique was further enhanced.In 2002, Miles (8) used a flowable composite in indirect bonding. The most important advantage of this resin was to fill the voids of the custom base with its favorable viscosity.With the advancement of technology, computers entered the practice of orthodontics, thereby enhancing the indirect bonding technique. Several companies offer three-dimensional computer-aided design and computer-aided manufacturing (3D CAD-CAM)-generated methods for the fabrication of indirect bonding trays. In one of these, Suresmile (Orametrix Inc.; Dallas, USA) system (9), teeth are scanned using an intraoral scanner, and computer generated 3D images are produced. These 3D images are used for digital set-up, and the brackets are placed in appropriate regions of the teeth. The customized transfer trays for in...
