OBJECTIVES Satisfactory bonding of orthodontic attachments to amalgam is a challenge for orthodontists. The aim of this in vitro study was to compare the shear bond strength of stainless steel orthodontic brackets to silver amalgam treated with sandblasting and Er,Cr:YSGG laser. STUDY DESIGN Fifty-four amalgam discs were prepared, polished and divided into three groups: In group 1 . Adhesive techniques are now used for many dental restorative materials, including amalgam. Several generations of dentine bonding agents have been developed, mainly for bonding composite resins.

  The aim of this research is to evaluate cyclic (CSBS) and static shear bond strengths (SSBS) of metal orthodontic brackets bonded to composite laminates using different conditioning protocols. A total of 80 direct nanofilled composite laminate veneers were prepared on permanent incisors and divided into four equal groups according to different surface treatments. With increased popularity of orthodontic treatment and advances in the esthetic appearance of attachments, more adults are visiting orthodontic clinics. Bracketing of these patients may frequently require bonding to crown-and-bridge restorations fabricated from porcelain and precious metals in addition to amalgam restorations.

Bonding orthodontic attachments to molars is difficult in the presence of extensive buccal amalgam by:   Bonding orthodontic attachments to molars is difficult in the presence of extensive buccal amalgam restorations.

The purposes of this study were (1) to examine different amalgam surface preparations, (2) to examine properties of adhesive cements to amalgam, (3) to determine the most shear-resistant bonding technique and (4) to discuss whether these shear bond strengths were of Cited by:   Abstract.

The aims of this study were to compare, in vitro, the shear bond strength (SBS) of stainless steel orthodontic brackets bonded to silver amalgam with the use of three different intermediate resins and two different adhesives, and to evaluate bond failure -five amalgam specimens were divided into three equal groups.

In groups 1 and 2, the brackets were bonded with Cited by: 9. Objectives: This study sought to assess the shear bond strength of orthodontic attachments to amalgam surfaces using Assure Universal Bonding Resin after different surface treatments.

Methods: This in-vitro experimental study was conducted on amalgam samples in eight groups of surface roughening with di. Adhesion of bonded orthodontic attachments to dental amalgam: In vitro study. Am J Orthod Dentofacial Orthop ; Am J Orthod Dentofacial Orthop ; Cited by: 3.

T he concept of adhesion of dental materials to enamel was first introduced in by Michael G. Buonocore [1] and only in there was a description of bonding orthodontic brackets to enamel.

Objectives: To determine the success of bracket retention using an adhesion promoter with and without the additional microabrasion of enamel.

Materials and Methods: Fifty-two teeth with severe dental fluorosis were bonded in vivo using a split-mouth design where the enamel surfaces of 26 teeth were microabraded with 50 μm of aluminum silicate for 5 seconds under rubber dam and high volume.

Objective: The aim of this study was to evaluate in vitro shear bond strength (SBS) and in vivo bond survival rates of brackets bonded using orthodontic indirect bonding als and Methods: For the in vitro study, the first group was direct bonding control group.

In Groups II and III, bonding was performed with indirect bonding resins that were either chemically or light-cured. Adhesion of bonded orthodontic attachments to dental amalgam: In vitro study. Am J Orthod Dentofacial Orthop.

;(5) doi/s (99) Jost-Brinkmann PG, Drost C, Can S. In orthodontics, the scientific interest regarding adhesion is focused on optimizing adherents: metallic or aesthetic bracket base conditioning, creating aesthetic brackets with improved mechanical properties, enamel conditioning and artificial surface conditioning (aesthetic veneers and crowns).

In order to investigate the interfaces between adherents there are several invasive (destructive. The aims of this study were to compare, in vitro, the shear bond strength (SBS) of stainless steel orthodontic brackets bonded to silver amalgam with the use of three different intermediate resins.

However, in adult patients with dental restorations, bonding onto composite, amalgam, laminate, or ceramic surfaces is required, and this presents new problems to orthodontists, as the bond strengths of orthodontic attachments is lower to these surfaces than to enamel surfaces.
