Filter by:Twenty patients need therapeutic extraction of the maxillary first premolars with subsequent retraction of the maxillary canines, will be divided randomly into two groups, and will randomly assigned to one side of the maxillary arch at the first premolar region, and the other side served as the control. Canine retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 150 g of force per side. Soldered transpalatal arch will be used as an anchor unit. The dento-alveolar changes will be assessed immediately before retraction and after 6 months using CBCT.

Pre- and post distalization dental casts will be evaluated to study rate of canine distalization, over a follow-up period until a Class I canine relationship will be achieved. The levels of Pain and discomfort will be monitored using a questionnaire with a VAS scale administered three times during the first day after prf injection.
The objective of this 2-arm parallel double blinded randomized controlled trial is was to evaluate and compare the treatment effects of PowerScope and Forsus in the treatment of Class II division 1 malocclusion. Patient comfort and operator convenience was also assessed and compared .
The main objective of this prospective, controlled clinical study is: 1. To compare the treatment effects of PowerScope2 and Forsus Fatigue Resistant Device in patients with Class II divison1 malocclusion. 2. To compare the treatment effects of PowerScope2 and Forsus Fatigue Resistant Device with the control group. The null hypothesis for this study is that Forsus and PowerScope2 are equally effective in the treatment of ClassII div1 malocclusion.
This study aims to evaluate and compare the skeletal, dental and soft tissue changes, the levels of pain and discomfort and the effect on periodontal health and teeth vitality associated to traditional corticotomy and flapless corticotomy in the retraction of upper anterior teeth. 40 patients requiring extraction of maxillary first premolars and maximum anchorage to retract the upper anterior teeth will participate in the study. They will be divided randomly into two groups : flapless corticotomy (20 patients) and traditional corticotomy (20 patients). Pre-retraction, corticotomy will be performed in the maxillary anterior segment. The skeletal, dental and soft tissue changes will be performed using lateral cephalometric radiographs which will be obtained pretreatment, pre and post en-masse retraction of the anterior teeth and we will also use the dental casts to evaluate the dental changes.
This experimental study will evaluate the effect of combined treatment with low-intensity pulsed ultrasound (LIPUS) and functional appliances (twin-block) on the correction of class II malocclusion, compared with the control group treated with functional appliances (twin-block) only. The study sample will consist of 40 patients with class II malocclusion. The sample will be allocated randomly into two groups: control group and experimental group. The functional appliance (twin-block) will be applied for all patients, while the low-intensity pulsed ultrasound (LIPUS) will be applied for the experimental group only. The skeleto-dental changes occurring after functional treatment will be assessed using cephalometric radiographs; pre and post- treatment changes for each group will be evaluated individually, and the two groups will be compared.
This experimental study will evaluate the effect of combined treatment with low-level laser and functional appliances (twin-block) on the correction of Class II malocclusion, compared with the control group treated with functional appliances (twin-block) only. The study sample will consist of 40 patients with Class II malocclusion. The sample will be allocated randomly into two groups: a control group and an experimental group. Functional appliance (twin-block) will be applied for all patients. Low-level laser will be applied for the experimental group only. The skeleto-dental changes occurring after functional treatment will be assessed using cephalometric radiographs; pre- and post- treatment changes for each group will be evaluated individually.
The purpose of this study is to compare the effectiveness and efficiency of labial versus lingual biocreative therapy in achieving en masse retraction of the maxillary anterior teeth in subjects with class II malocclusion requiring upper first premolar extraction.
the effectiveness of RME (Rapid Maxillary Expander) on the sagittal dental or skeletal parameters is still controversial because very little has been written regarding the behavior of antero-posterior mandibular changes in Class II growing subjects who underwent RME as the phase 1 treatment intervention. The reported significant occlusal improvement could be attributed to other reasons, ie, skeletal growth or the use of additional appliances during transition from mixed to permanent dentition. Moreover, the majority of the studies show some limits: they are not randomized, they are not prospective, and they have no control group or they use patients from growth studies as a source for the control group. The primary objective of the present investigation was to conduct a pilot randomized controlled trial (RCT) evaluating the changes in the antero-posterior mandibular position induced by bonded or banded RMEs compared with an untreated Class II control group
We aim to assess the treatment outcomes following upper incisors retraction accelerated by corticotomy procedure. So, we intend to randomize orthodontic patients with class II division I malocclusion into two groups: experimental group and control group. Both groups will start orthodontic treatment. Once a 0.019*0.025-inch stainless steel wire is fully engaged to the brackets, 1st premolars will be extracted. Canines will be retracted in the conventional manner. Then, the actual evaluation period starts when the upper incisors are retracted using two different methods.
