The aim of this study is to evaluate the levels of pain, discomfort and acceptance between two treatment modalities of Class III correction of growing patients in the late mixed dentition period.
The acceptance of orthodontic appliance is measured by the amount of discomfort occurring during orthodontic treatment. Different feelings can be encountered during the course of orthodontic treatment such as pressure, tension and pain. Pain is defined as an unpleasant feeling and a bad subjective experience combined with internal or external reason and it is considered as the most annoying factor during orthodontic treatment with fixed appliance. In a study by Oliver and Knappman, patients stated that the worse thing related to the orthodontic treatment was pain and 70% of the subjects suffered from pain during orthodontic treatment regardless the appliance' type. The fear from the pain is considered as the most important factor that not encourage patient to ask orthodontic treatment.Many studies demonstrated that there were no differences in the amount of the pain resulted from the orthodontic treatment between males and females [2, 5]. In a study of the reasons which make patient stopped the orthodontic treatment, Haynes found that the pain was the first reason, whereas the second one was the effect of the orthodontic appliance on the patient's daily social life.
When reviewing the medical literature, few studies have been found to identify the patient acceptance degree to the orthodontic appliance used for treating Class III cases in general and Class III functional appliances in particular.Removable appliances were evaluated by a series of publications by Sergl et al in Germany.Additionally, when rigorous study designs are considered utilizing randomized controlled trials (RCTs), there are only few RCTs in the dental literature that evaluated patients' responses towards orthodontic treatment. Idris et al., evaluated Class II growing patients undergoing functional orthopedic corrections, whereas Khattab et al., compared labial brackets versus lingual brackets in terms of speech and functional impairments. Recently, Saleh et al., evaluated the levels of acceptance towards the removable mandibular retractor (RMR) when treating young children with Class III malocclusion in the late primary dentition and early mixed dentition (i.e. between 5 and 9 years) and found high levels of acceptance recommending the need for further analysis of patients' responses to this appliance in older age groups.
Bone-anchored intermaxillary elastics have been proposed as a method of correcting Class III deformities. Although this method was compared to the removable mandibular retractor in terms of skeletal and dentoalveolar changes, but the published paper did not report any information about the associated levels of pain and discomfort as well the general acceptability to this treatment modality.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Removable Mandibular Retractor | Active Comparator | Patients in this group will be treated by the Removable Mandibular Retractor (RMR) in order to get rid of the anterior cross bite. This appliance is removable. |
|
| Bone-anchored intermaxillary Traction | Experimental | Patients will be treated using bone-anchored intermaxillary traction. Class III elastics will be extended from the Adam's clasps placed in the upper removable appliance towards the heads of mini-implants placed between the permanent canine and lateral incisors on either side of the lower dental arch. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Removable Mandibular Retractor | Device | The appliance will be used 18 hours per day. It can only be removed for eating meals. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Change in the sensation of tension or pressure | Patients will be asked this question about their sensation of tension or pressure (Item no 01): Do you have a sense of tension and pressure in your soft tissues? A standardized questionnaire will be used to assess pain, discomfort and functional impairments' levels during the first six months of treatment. A four-point Likert scale is going to be used consisting of: (not at all), (little), (much) or (very much) to which points 0, 1, 2 and 3 respectively are going to be ascribed. Each questionnaire is going to be completed by the child in the presence of one of his/her parents. | Questionnaires will be filled at the following assessment times: one day following appliance insertion (T1), one week (T2), six weeks (T3), three months (T4) and after 6 months of appliance insertion (T5) |
| Change in the perception of pain | Patients will be asked this question about their perception of pain (Item no 02): 'Have you experienced any degree of pain?' A standardized questionnaire will be used to assess pain, discomfort and functional impairments' levels during the first six months of treatment. A four-point Likert scale is going to be used consisting of: (not at all), (little), (much) or (very much) to which points 0, 1, 2 and 3 respectively are going to be ascribed. Each questionnaire is going to be completed by the child in the presence of one of his/her parents. | Questionnaires will be filled at the following assessment times: one day following appliance insertion (T1), one week (T2), six weeks (T3), three months (T4) and after 6 months of appliance insertion (T5) |
| Change in the perception of speech | Patients will be asked this question about any change encountered in the articulation of sounds (Item no 03): 'Do you feel that your articulation has changed?' A standardized questionnaire will be used to assess pain, discomfort and functional impairments' levels during the first six months of treatment. A four-point Likert scale is going to be used consisting of: (not at all), (little), (much) or (very much) to which points 0, 1, 2 and 3 respectively are going to be ascribed. Each questionnaire is going to be completed by the child in the presence of one of his/her parents. |
