mushroom-arch technique introduced by Fujita in the 1970s,1,2 Takemoto and Scuzzo developed the lingual straight-wire (LSW) technique in 1995.3,4 Mushroom archwires typically require vertical steps and insets between the canines and first premolars, necessitating complicated wire bends that can affect treatment outcomes. The LSW method eliminated this problem, but the thickness of the lingual b...

Introduction: The opinion on the ‘straight-wire’ concept has been evolving since its origin, characterized by faithful followers or absolute skepticism. Currently, it seems reasonable to state that most professionals have a more realistic and critical viewpoint, with an attitude that reveals Orthodontics’ maturity and greater knowledge on the technique. The most relevant criticisms refer to the...

STATEMENT OF PROBLEM One of the major outcomes of orthodontic treatment is the apical root resorption of teeth moved during the treatment. Identifying the possible risk factors, are necessary for every orthodontist. PURPOSE The aim of this study was to compare the rate of apical root resorption after fixed orthodontic treatment with standard edgewise and straight wire (MBT) method, and also t...

This article introduces the application background and research overview of esophageal stent. The finite element models of two different forms of braided esophageal stent, such as cup-sphericalshaped and straight shaped, are created. Based on the configuration of material model selection and boundary condition, the stress and axial elongation of the stent with different wire numbers, different ...

AIM The aim of this study is to present a case of large maxillary median diastema closed by bodily movement of central incisors using Bapat power arm (BPA). MATERIALS AND METHODS After extraction of mesiodens, a power chain with a force of 120 gm was applied to BPA ligated to preadjusted edgewise brackets bonded to maxillary central incisors to move them over round steel wire for closure of r...

BACKGROUND The aim of this study is to investigate the relative stiffness of straight and mushroom lingual archwires of different diameters, cross sections and alloys, plotting their load/deflection graphs and using a modified three-point bending test. METHODS Fujita's mushroom archwires and straight lingual archwires of different diameters, cross sections and alloys were derived by a virtual...

: To compare the aligning efficiency, pain experienced by patient during alignment and post third order values of anterior teeth in I arch (study) group conventional NiTi (control) wire group. A prospective clinical study. total 40 dental arches (maxilla/mandible) were divided into 2 study groups with 20 each based on selection criteria. Group I. Twenty (maxillary/mandibular) having 0.018” prea...

Three patients with rheumatic mitral stenosis were treated with percutaneous mitral valvotomy. A Brockenbrough catheter was advanced transseptally into the left atrium and then into the left ventricle over a long guide wire. An angle wire loop retriever was advanced through a 10 Fr straight catheter via the femoral artery into the left ventricle. The retriever was used to catch the flexible end...
