Abstract:
Objective To study the treatment for orthodontic traction of the impacted tooth with glass ionomer cement to improve adhesion efficiency. Methods A total of 46 orthodontic traction of the impacted tooth cases (46 bonded or-thodontic attachments impacted teeth pulled) were selected from March 2005 to December 2012 with traction of im-pacted tooth in our hospital of stmatology department, 46 orthodontic patients were divided into two groups randomly.Following closed-eruption surgery. Experimental group were bonded with glass ionomer cement, the control group with enamel adhesive resin. Compared the failure rates for the first time and after half months. Results The success rate of the first bond, the experimental group was 100%, the control group was 52%. The expulsion rate after half months,0 for the experimental group, the control group was 25%. Initial success rate and after half months expulsion rates were significantly different between the two groups (P<0.01). Conclusion Impacted teeth should be routinely applied glass ionomer cement bonded orthodontic attachments to improve the success rate and reduce postoperative loss rate, to avoid the second surgery.
