Filter by:There is a scarcity in the current literature regarding such appliance and its effect on distalizing the first maxillary molar in absence of the second molar. Therefore, this study was made to evaluate the effect of bilateral distalization of upper first molars in a group of patients after extraction of maxillary second Molars using infra zygomatic mini implants.
The aim of this study is to determine the effect of orthognathic surgery on nutritional status, anthropometric measurements, food consumption levels, physical activity levels, biochemical parameters, chewing ability and oral-health impact profile.
Fixed Functional Appliances comparisons in treatment of orthodontic class II malocclusion cases
Few studies had investigated the effectiveness of segmental retraction. As a result of that, this study was concerned about comparing retraction rate of maxillary incisors between buccal and palatal mini-implant supported retraction groups in Class II division 1 non growing patients for 3 months interval.
Patients who have severe crowding that requires four premolars extraction will be treated in this study. The efficacy and effectiveness of in-house clear aligners therapy compared with vestibular fixed appliances in the treatment of severe crowding malocclusion cases requiring the extraction of first premolars will be evaluated using Little's irregularity index (LII), Peer assessment rating index (PAR), and treatment duration. There are two groups: First group (Experimental): the patients in this group will be treated using clear aligners. Second group (Control): the patients in this group will be treated using fixed appliances.
This study will aim to evaluate the effect of skeletally anchored extrusion arch on the dentofacial structures in patients with anterior open bite (AOB).
This study will be directed to evaluate The effect of two different types of fixed functional appliances on the temporomandibular joint. Study design: Prospective randomized clinical study. Study setting and population: This study will be conducted on twenty orthodontic patients. The number of patients was dependent on a power study. Sample size calculation was based on the observed average effect size derived from previous article addressing "the effect of skeletally anchored Forsus FRD using miniplates for the treatment of Class II malocclusion
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.
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.
