Filter by:The goal of this clinical trial is to show the effect of patient specific lateral nasal wall osteotomy to the pterygomaxillary separation during Le Fort I down-fracture. Participants will be divided into two treatment groups. In study group, surgery planned according to the patients' indivudial anatomy and in the conventional group, surgery planned according to mean anatomical datas. Researchers will compare patient specific lateral nasal wall osteotomy to see if it affects the pterygomaxillary junction seperation during le fort I downfracture.
This clinical trial aimed to compare the effect of immediate light short Class II elastics versus conventional Class II elastics on the skeletal, dental and soft tissues in patients with Class II malocclusion. Participants with class II malocclusion divided into 2 groups; early group wore immediate light short Class II elastics and conventional group wore conventional Class II elastics on rigid stainless steel arch wires.
The primary aim of the study is to compare the perception of pain and discomfort with two different protocols of attachments' placement during clear aligner therapy: the conventional protocol (CP), when attachments' placement is performed are placed at the delivery of the first aligner; the delayed protocol (DP), when the attachments' placement is performed at the delivery of the third aligner. The rationale of this study is to evaluate whether dividing the two phases most associated with the onset of pain and discomfort, namely the initiation of aligner therapy and the placement of attachments, can improve patients' quality of life during clear aligner treatment. Patients' discomfort will be evaluated with a questionnaire adapted by OHIP-14 (Oral Health Impact Profile 14).
use new hybrid aesthetic functional appliance for treatment of class II div 1 malocclusion.
: the purpose of this study was to evaluate the dento-skeletal effects of the mini-implant supported Twin Block versus the incisal capped appliance in the treatment of skeletal class II patients with mandibular retrognathism. Methods: Twenty patients with skeletal class II mandibular retrusion were included in the study. They were recruited with a random and equal allocation into 2 groups. The first group was treated with incisal capped TB without skeletal anchorage. The second group were treated with mini-implant supported TB. The mini-implants were inserted in the inter-radicular region between the mandibular second premolar and first molar. Intra-oral elastics were attached from the mini-implant to the wire hook in the canine region of the lower part of the TB and they were changed every 24 hrs. 100 to 150 gm of force was applied. Cephalometric radiographs were acquired at the beginning (T1) and end of treatment (T2). The paired-samples and independent-samples t-tests were used to evaluate and compare the changes within groups and between groups, respectively.
The goal of this randomized clinical trial is to compare the effect of LLLT in adolescent patient with class II malocclusion. The main question it aims to answer is: • is there a difference in the amount of distalization between laser and control groups? Participants will received bony supported distal jet. Researchers will compare laser group with control group to see if there is a difference in amount of distalization between groups.
The goal of this prospective, single-arm clinical trial is to evaluate the speech performance of children with anterior dental crossbite before and after correction. Also, to assess the impact of early interceptive orthodontic treatment in the mixed dentition stage to correct the anterior dental crossbite on the quality of life of children. Fifty children of both sexes aged from 8 to 10 years were enrolled and evaluated using the study's inclusion & exclusion criteria. before beginning interceptive orthodontic treatment, each child underwent full mouth treatment. then, using a removable anterior expansion screw along with posterior bite planes to treat the anterior crossbite. All children were subjected to the Protocol of speech evaluation before appliance insertion and after complete correction of anterior crossbite. Also, the Child Perceptions Questionnaire (CPQ 8-10) in the Brazilian version was used to gauge how the anterior crossbite affected the children's oral health-related quality of life.
The present study will be performed to Evaluate the treatment outcome of anterior open bite by temporary anchorage device on buccal and palatal mini screws
Building artificial intelligence models for diagnosis of anterior open bite malocclusion
To evaluate whether the use of augmented reality (AR) for visualizing 3D models can be a valuable addition to patient education regarding orthognathic procedures compared to using only 2D visualization (on a computer screen).
