ABSTRACT

Orthodontic retainers are referred to as the appliances which are used to hold the teeth in position. These are prescribed to the patients after surgery or any method of realigning the teeth. Orthodontic retainers are the custom-made devices, which are usually made of wires or clear plastic. These can be either removable or fixed retainers. If this retention phase fails, there are chances of relapse. Therefore, this study aims at assessing the stability of orthodontic retainers. This retrospective study was done by collecting data from the patients records. The data was obtained by the records of the patient who visited Saveetha Dental College and Hospitals. The patients who had undergone orthodontic treatment followed by placement of orthodontic retainers were considered for this study. The failure evaluation in all these patients were assessed. This study includes patients who were given different types of retainers [removable, fixed, etc.]. The various retainers were noted and analyzed. Out of 345 patients who were analyzed for the failure evaluation of orthodontic retainers, 184 patients [36.6%] were female and 161 [32.0%] were males. The mean age group of the patients is 24.21. When assessed for the failure associated with the arch, the upper arch had the highest failure rates of 29.6%, followed by lower arch [27.6%] and in cases of both arch [11.1%]. The various retainers that were given for the patients following the orthodontic treatment includes Hawley’s appliance which has the higher prevalence of 56.1%. The failure rates associated with relapse was [2.0%], and the failure associated with breakage includes 0.8%. The cases where there were no failure rates include 65.8%. The prevalence of failure rates of orthodontic retainers was lesser in this study. Most of the retainers were given in the maxillary arch and they were Hawley’s removable retainer. In comparison of relapse rates and breakage cases, the relapse rates were higher. Keywords: failure evaluation, orthodontic retainers, relapse, breakage, removable, fixed retainers
