Filter by:study will be directed to evaluate the effect of low-level laser therapy during maxillary molar distalization using a skeletally anchored appliance
The study aims to compare the effect of periodontal accelerated osteogenic orthodontics (PAOO) with horizontal or vertical releasing incisions on operation time, healing, adverse effects, and effectiveness of bone augmentation. Methods: A total of 22 patients requiring PAOO surgery due to orthodontic treatment were enrolled in this trial, and randomly divided into test or control group, consisting of 11 subjects in each. The test group will receive PAOO with horizontal extending incisions on both sides of the flap; while the control group will receive PAOO with vertical releasing incisions; the two groups use the same surgical technic except for the incision design. Outcome measures include: operation time, postoperative scar, radiographic data (alveolar height and alveolar ridge thickness), gingival thickness, etc. Clinical evaluation will be performed at 1 week, 2 weeks, 3months, 6 months and 12 months after operation.
the objective of the current study is to compare the dentofacial effects of the mini-plate anchored Herbst appliance Versus the dentally anchored Twin force bite corrector Appliance in Young Adult Class II Orthodontic Patients with retruded mandible.
study will be directed to evaluate two approaches of microosteoperforations during skeletally anchored maxillary expansion
This experimental study will evaluate the effect of an esthetic Twin-block appliance on the correction of class II malocclusion compared with the traditional Twin-block appliance. The study sample will consist of 50 patients with class II malocclusion. The sample will be allocated randomly into two groups: the control group and the experimental group. The traditional Twin-block appliance will be applied for the control group patients, while the esthetic Twin-block appliance will be applied for the experimental group patients. The dentoskeletal, soft tissue changes and esthetic and functional efficacy occurring after functional treatment will be assessed using cephalometric radiographs and profile photographs, pre and post-treatment, and a questionnaire. Changes for each group will be evaluated individually, and the two groups will be compared.
The different types of brackets (e.g., self-ligating and conventional brackets), and the various acceleration methods (e.g., corticotomy) cause varying degrees of pain and discomfort. This study will assess pain, discomfort, and other patient-centered outcomes in adults with severe crowding on the upper jaw requiring two first premolars extraction. There are three groups: The first group (control group): the patients in this group will be treated using conventional brackets alone. The second group (Experimental group): the patients in this group will be treated using self-ligating brackets alone. The third group (Experimental group): the patients in this group will be treated using self-ligating brackets associated with flapless corticotomy.
The study will monitor changes induced by orthodontic treatment and in the retention period, two years after the end of orthodontic treatment. The alignment of teeth, hygiene and gingiva will be assessed. Efficiency of two types of fixed appliances in active phase will be compared - esthetic and metal. Efficiency of two types of retention appliances in retention phase will be compared - fixed and removable. The benefits of orthodontic treatment to be studied are aesthetic concerns, dental self-confidence, self-esteem, social contacts, psychological influences, and chewing limitation. The stability of personality traits, body image and perfectionism will also be analyzed, as well as the extent to which these dimensions modify the reporting of psychosocial effects of malocclusion treatment.
Bilateral sagittal split osteotomy (BSSO) is considered the main osteotomy design in corrective mandibular surgery, however abnormal anatomical configuration of the posterior mandible with rolled out inferior border and thin mandibular rami with cortically adherent inferior alveolar nerve may interfere with the utilization of this osteotomy. The aim of this study is to introduce a novel modification of the intraoral inverted L ramus osteotomy (ILRO) to overcome these limitations in mandibular setback surgery. preoperative CBCT was requested for virtual planning and fabrication of cutting and drilling guides. Cutting lines were outlined to be consisted of four cuts; lateral ostectomy to uncover and lateralize the inferior alveolar nerve (IAN), posterior cut run horizontally from the anterior border of the ramus to a point just above the mandibular foramen, two anterior vertical cuts run from the anterior end of the lateral ostectomy to the inferior mandibular border. The guide was removed and the osteotomy lines were completed then the mandibular setback was oriented and fixed using pre-bent plates osteosynthesis. Inferior alveolar nerve function was regained perfectly one year post-operatively. This procedure introduces a robust alternative to the BSSO osteotomy in some cases of mandibular setback surgery.
Patients at the Orthodontic Department of the University of Damascus Dental School will be examined and subjects who meet the inclusion criteria will be included. Then, initial diagnostic records (diagnostic gypsum models, internal and external oral photographs, and radiographic images) will be studied to ensure that the selection criteria are accurately matched. This study aims to compare two groups of patients with moderate crowding of the lower anterior teeth. Experimental group: the patients in this group will be treated with periodontally accelerated osteogenic orthodontics Control group: the patients in this group will be treated using fixed appliances without any acceleration method.
Due to the high prevalence of malocclusions in Mexico and the existing concern to improve aesthetics, function (chewing), or both, patients resort to orthodontic treatment. The patient may experience pain during treatment due to the release of different chemical mediators such as RANK-L. Analgesic and anti-inflammatory medications such as acetaminophen and ketorolac are used to control pain during orthodontic tooth movement. These drugs can inhibit the expression of RANK-L which can affect tooth movement, inhibiting bone remodeling. The orthodontist should indicate the drug that is safest for the patient without affecting treatment or tooth movement.
