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 کاملA Silver/Silver Sulfide Selective Micro-Electrode Prepared by Chemical Treatment of Silver Wire
The preparation conditions and the performance of a small size Ag/Ag2S selective electrode are described. The analytical behaviour of this electrode, made by chemical treatment of a silver wire, is described in terms of potential concentration curves, standard potential, lifetime and electrode selectivity. A series of electrodes have been prepared and investigated. Their response and selectivit...
متن کاملMemotain: A CAD/CAM nickel-titanium lingual retainer.
Approximately 1/2 of maxillary and 1/5 of mandibular multi-stranded lingual retainers fail during retention in some form, either bond failure or wire breakage. Memotain is a new CAD/CAM fabricated lingual retainer wire made of custom-cut nickel-titanium, as an alternative to multi-stranded lingual retainers. It offers numerous perceived advantages to the traditional multi-stranded stainless ste...
