Coated nickel titanium archwires and their uncoated counterparts: In-vitro contemporary comparison of unloading forces.

Objective: To compare the unloading forces between aesthetic nickel titanium (NiTi) wires coated with rhodium and epoxy resin, as well as their uncoated equivalents. Additionally, intragroup comparisons between the different deactivation forces were evaluated, and the inner alloy cores were determined.

Material And Methods: Forty-four 0.

Comparison of gingival display in smile attractiveness among restorative dentists, orthodontists, prosthodontists, periodontists, and laypeople.

Statement Of Problem: Multidisciplinary treatment needs a common goal, and dentists should understand the esthetic perception of laypeople and the other specialists involved. Such information is sparse.

Purpose: The purpose of this cross-sectional study was to compare the influence of gingival display on perceived smile esthetics among restorative dentists, orthodontists, prosthodontists, periodontists, and laypeople.

Two-Year Follow-up of Multidisciplinary Treatment Using Digital Smile Design as a Planning Tool for Esthetic Restorations on Maxillary Midline Diastema.

One of the challenges posed by diastema closure treatment in the presence of tooth size discrepancy is to achieve adequate distribution of the spaces between the teeth. The use of the Digital Smile Design can assist the clinician in visualizing and measuring dentogingival discrepancies with maximum predictability. The present clinical case describes an approach to space distribution with assistance of the digital tool, allowing adequate restorative procedures.

Intrusion of maxillary molar using mini-implants: A clinical report and follow-up at 5 years.

This clinical report describes a straightforward alternative treatment for adult patients with extruded maxillary molars, who are reluctant to use fixed appliances and complex mechanics. The maxillary molar supereruption of a 57-year-old woman was treated using buttons bonded to the buccal and palatal surfaces of the molars, 2 mini-implants, and elastomeric chains. The intrusion was achieved in 5 months.

Evaluation of an alternative technique to optimize direct bonding of orthodontic brackets to temporary crowns.

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 diamond bur followed by conventional direct bonding by means of light-cured composite resin; discs in group 3 were bonded by means of CAAR (alternative adhesive); and discs in group 4 had surfaces roughened with a diamond bur followed by direct bonding by means of CAAR. Shear bond strength values were determined after 24 hours by means of a universal testing machine at a speed of 0.

Correlation between the Rotation of the First Molars and the Severity of Class II Division 1 Malocclusion.

This study aimed to evaluate the potential correlation between the severity of Class II division 1 malocclusion and the magnitude of mesiopalatal rotation of the maxillary first molars. Scanned images of 104 cast models were grouped according to the severity of Class II malocclusion as follows: Group 1, 1/4 Class II malocclusion; Group 2, 1/2 Class II malocclusion; Group 3, 3/4 Class II malocclusion; and Group 4, complete Class II malocclusion. The rotation was measured using parameters described by Henry, Friel, and Ricketts, referred to as indicators 1, 2, and 3, respectively.

Evaluation of Fracture Resistance of Orthodontic Mini-implants in the Transmucosal Profile Region.

Aim: This study sought to compare the fracture resistance of three trademarked orthodontic mini-implants in the transmucosal profile region. Thirty-six mini-implants of three different brands, separated into groups I, II and III, were tested. Each group consisted of 12 mini-implants of 6 mm in length.

Deflection Evaluation of Thermoactivated Nickel-Titanium Archwires after Heat Treatment on their Distal Ends.

Objective: This study evaluated in vitro the mechanical changes of 0.018" (0.45 mm) and 0.

Distalization of maxillary molars using a lever arm and mini-implant.

This article describes the orthodontic treatment of a young woman with a Class II malocclusion and maxillomandibular prognathism. One orthodontic mini- implant was placed in the posterior area of the palate to provide anchorage for?a transpalatal arch. The force for molar distalization was applied using an elastic chain from the lever arm inserted on the transpalatal arch to the mini-implant.

In vitro evaluation of an alternative method to bond molar tubes.

Unlabelled: Despite the advances in bonding materials, many clinicians today still prefer to place bands on molar teeth. Molar bonding procedures need improvement to be widely accepted clinically.

Objective: The purpose of this study was to evaluate the shear bond strength when an additional adhesive layer was applied on the occlusal tooth/tube interface to provide reinforcement to molar tubes.
