Evaluation of the Dento-skeletal effects of Mini-implant Assisted Rapid Palatal Expansion in a sample of Adult Orthodontic Patients: A prospective clinical study

ABSTRACT The midpalatal suture has bone margins with thick connective tissue interposed between them, and it does not represent the fusion of maxillary palatal processes only, but also the fusion of palatal processes of the jaws and horizontal osseous laminae of palatal bones. Changing it implies affecting neighboring areas. It has got three segments that should be considered by all clinical analyses, whether therapeutic or experimental: the anterior segment (before the incisive foramen, or intermaxillary segment), the middle segment (from the incisive foramen to the suture transversal to the palatal bone ) and the posterior segment (after the suture transversal to the palatal bone ). Rapid palatal expansion might be recommended for patients at the final pubertal growth stage, in addition to adult patients with maxillary constriction. It represents a treatment solution that can potentially avoid surgical intervention. When performed in association with rapid palatal expanders, it might enhance the skeletal effects of the latter. Of the various designs of expansion appliances, MARPE (miniscrew-assisted rapid palatal expander) has been modified in order to allow its operational advantages and outcomes to become familiar in the clinical practice.

Orthodontic Separators

Introduction: Pain has been the most common and foremost reason for discontinuing the orthodontic treatment. The patients usually experience pain in Orthodontic treatment during separator placement, wire placement, headgear wear, and rapid palatal expansion. Placement of orthodontic separators (brass wire, elastomeric, spring-type steel separators, and latex elastics) results in a painful experience. Therefore the purpose of the study is to assess the pain perception among the patients seeking orthodontic treatment. Methods: This study was carried out amongst 120 (53 male and 67 female) patients seeking orthodontic treatment. Elastomeric separators were placed mesially and distally to the first molars and the participants were given a self-administrated Universal pain assessment Tool to document perceived pain and pain upon chewing, using a visual analog scale for seven days. Total scores were calculated and descriptive statistics in the form of a number (mean) and percentage were calculated. Results: This study showed a mean score for perceived pain of each day to be 7.16, 7.1, 6.05, 4.67, 3.69, 2.88, and 2.27 respectively with a mean of 4.831 +/- 1.273. Similarly, the mean score for pain on chewing was 8.21, 7.53, 6.62, 5.19, 4.38, 3.65, and 3 with a mean of 5.5119 +/- 1.269. Conclusions: There was a significant difference in pain perception among the male and female participants, females having higher pain perception. There was a significant difference in pain perception between the Adolescent and Adult in both normal life and during eating.
