Closure of interdental spaces using proximal build-ups with resin composite is considered to be practical and conservative. However, a comprehensive approach combining two or more treatment modalities may be needed to improve esthetics. This case report describes the management of a patient with multiple diastemas, a peg-shaped lateral incisor and midline deviation in the maxillary anterior are...

BACKGROUND The aim of the present study is to evaluate the effects of a fluoride-releasing composite resin bonding material on reducing enamel demineralization underneath and around orthodontic brackets and compare that with a conventional adhesive system. MATERIALS AND METHODS Buccal surfaces of 10 intact extracted premolar teeth were divided into two parts with nail varnish and stainless st...

This study assessed bonding of orthodontic brackets to porcelain teeth using two different surface preparation techniques and comparing two bonding systems, Fuji Ortho L.C. and Transbond. Four groups of 20 porcelain premolar teeth were bonded with metal orthodontic brackets (0.022 inch Minitwin, 3M Unitek) according to the following protocol: Transbond with a phosphoric acid etch (group 1), Tra...

UNLABELLED In orthodontics, fixed appliances placed in the oral cavity are colonized by microorganisms. OBJECTIVE The purpose of this study was to quantitatively determine the independent bacterial colonization of S. mutans and S. sobrinus in orthodontic composite resins. MATERIAL AND METHODS Seven orthodontic composite adhesives for bonding brackets were selected and classified into 14 gro...

Four different orthodontic applications of a polyethylene fiber material are shown and discussed in case reports. Ribbond (Ribbond Inc, Seattle, Wash), a bondable, reinforced polyethylene fiber material, was successfully used in a fixed orthodontic retainer, a space maintainer, a temporary postorthodontic fixation device to attach a pontic to abutment teeth during periodontal therapy, and a pos...

After orthodontic brackets debonding, the remaining resin has to be removed. The purpose of this study was to determine the most efficient method as well as to introduce a new method of composite removal. The study was carried out on a sample of 30 premolars, extracted for orthodontic purposes. Brackets had been bonded using the Ortho One Bisco composite resin. After the removal of brackets, sa...

background. failure of orthodontic bracket bonds is a common occurrence during orthodontic treatment. different tech-niques have been suggested in the literature to remove resin residues from the bracket bases and enamel surfaces to prepare the surfaces again after debonding. this study attempted to compare multiple rebond shear strengths (sbs) of debonded brackets following preparation with sa...

Aim and objectives: To determine the shear bond strength of laser cured composite resin and compare with that of visible light cure resin and evaluate it’s clinical usefulness. Materials and methods: An argon laser with a wavelength of 488-500nm and a power density of 2.10 mW/cm and an optical diameter of 6mm with a curing time of 10 seconds was employed as against the visible light cure with a...

OBJECTIVE To compare shear bond strength of different direct bonding techniques of orthodontic brackets to acrylic resin surfaces. METHODS The sample comprised 64 discs of chemically activated acrylic resin (CAAR) randomly divided into four groups: discs in group 1 were bonded by means of light-cured composite resin (conventional adhesive); discs in group 2 had surfaces roughened with a diamo...

BACKGROUND Comparison of the demineralization potential of four luting cements, i.e. zinc phosphate, conventional glass ionomer cement (GIC), resin-modified GIC and acid modified composite resin. MATERIALS AND METHODS This study was conducted on 75 extracted premolar teeth, which were grouped into five, each group containing 15 teeth. Groups were non-banded control, teeth cemented with the ab...
