Exactive Tie-Back - An Accurate Active Tieback.

Abstract

Active tiebacks using elastomeric modules are preferred for space closure in most cases. Elastomeric ring should be stretched by equal amount on both sides for equalforce delivery and to avoid unwanted complication like shift in mid-line, asymmetric space closure. Elastic tiebacks were originally described using an elastomeric module, stretched to twice its normal size but in clinical situations, stretch of elastomeric rings are diffcult to measure intraorally. This paper introduces a manually fabricated guiding system that will allow the clinician to accurately activate active tie-back bilaterally without fear of over/under stretching the module to twice its original size. With the help of straight length 0.021" 0.025" SS wire and cold cure acrylic a guiding stent is fabricated. Guiding loops were made with 0.009" ligature wire around this stent, which can be placed along with active tieback. This "Exactive tieback" with the help ofguiding loop template is easy to fabricate and use. It is an accurate, effective, and predictable method for placement of symmetrical active tie-backs."
