Rebond strength of bonded lingual wire retainers.
There is no consensus in the literature concerning the rebonding procedure for orthodontic retainers. The aim of this in vitro study was to evaluate the bond and rebond strength of retainers bonded to enamel surfaces with and without composite remnants. The retainers were bonded with Excite and Tetric Flow on three different surfaces: clean enamel, enamel where the composite had been removed by...
متن کاملA new lingual straight-wire technique.
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...
متن کاملWire jigs for stabilizing lingual retainers.
T simple stabilizing jigs for bonded lingual retainer wires are easily fabricated from materials in the office, using the following procedure: 1. Bend a circular retentive tag into one end of an .031" stainless steel wire segment.* 2. Double-wind the wire 6-8mm from the tag to form a helix with an internal diameter of 3mm (A). 3. Bend the other end of the wire 90°, leaving a space of about 2mm ...
متن کاملDocument Expansion for Cross-Lingual Passage Retrieval
This article describes the participation of the joint Elhuyar-IXA group in the ResPubliQA exercise at QA&CLEF 2010. In particular, we participated in the English–English monolingual task and in the Basque– English cross-lingual one. Our focus was threefold: (1) to check to what extent information retrieval (IR) can achieve good results in passage retrieval without question analysis and answer v...
متن کاملNon-Wire Alternatives to Capacity Expansion
Distributed energy resources (DERs) can serve as non-wire alternatives to capacity expansion by managing peak load to avoid or defer traditional expansion projects. In this paper, we study a planning problem that co-optimizes DERs investment and operation (e.g., energy efficiency, energy storage, demand response, solar photovoltaic) and the timing of capacity expansion. We formulate the problem...
