Filter by:The study is aiming to evaluate the efficacy of Powerscope appliance in treatment of skeletal Class 2 malocclusion by three-dimensional image. Powerscope appliance is a hybrid fixed functional appliance used for treatment of Class II malocclusion with a retruded mandible.
The purpose of this research is to test which of four clear aligner attachment types is more efficient in extruding (erupting) maxillary lateral incisors vertically into correct position during orthodontic treatment.
the study aimed to clinically evaluate the effect of micro-osteoperforations on the rate of tooth movement, as evaluated by its effect on the rate of canine retraction.
This study aims to evaluate and compare the inclination of the lower and upper permanent first molars and the transversal width of the lower and upper jaws in individuals of different age groups to evaluate whether the existing anomaly at different ages in individuals with a bilateral posterior crossbite. For this reason, first molar tooth inclination and lower and upper jaw transversal width will be evaluated in adolescent and post-adolescent individuals with a bilateral posterior crossbite.
Various malocclusions require the extraction of the first premolars and retraction of the canines with the need for maximum anchorage. If the canines are pulled into the extraction space using the molar teeth for support, unwanted tooth movement occurs. This study aims to evaluate the effect of temporary anchorage devices and power arms, which are auxiliary orthodontic appliances in reducing undesirable tooth movements.
The aim of our research is to establish a link between malocclusions and oral dysfunctions. The clinical examination includes: caries screening (DMFT and dft scores), a quantification of dental plaque (Silness and Loë's plaque index) and orthodontic treatment need (Haute Autorité de Santé HAS). The functional examination includes improper mouth breathing, abnormal deglutition and incorrect position of tongue at rest.
The aim of this clinical prospective study will be directed to evaluate two approaches of micro-osteoperforations (MOPs) during orthodontic canine retraction.
Patients who have severe crowding that required four premolars extraction will be treated in this study. The effects of clear aligners therapy on oral health related quality of life (OHRQoL) in comparison with vestibular fixed appliances using the validated OHIP-14 tool during orthodontic treatment. So the aim of the study was to compare the changes in OHRQoL between patients receiving clear aligners or fixed appliances during the first year of the orthodontic treatment. 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 aims to assess the dental changes, periodontal health and the pulp vitality in mini-screw supported en-masse retraction associated with traditional or flapless corticotomy techniques. 40 adult patients exhibiting class II division 1 malocclusion requiring upper first premolar extractions followed by en-masse retraction will participate in the study. They will be randomly and equally distributed into two groups: traditional corticotomy (20 patients) versus flapless corticotomy (20 patients). The corticotomy procedure will be performed pre-retraction. The dental changes will be assessed using dental casts. The impressions will be taken after finishing the leveling and alignment phase and before starting the en-masse retraction (T0), 1 month (T1), 2 months (T2), 3 months (T3), 4 months (T4), and 5 months (T5) following the onset of en-masse retraction. The final impression will be considered at the end of the en-masse retraction (when the canines reach Class Ι relationship).
The force exerted by the rapid maxillary expansion (RME) appliances provides expansion of the transverse dimension by splitting of the midpalatal suture. This expansion results in three-dimensional (3D) changes in maxillary position which also effects circummaxillary surrounding structures. The aim of this randomized clinical trial (RCT) was to evaluate the effects of tooth-borne and tooth-bone-borne rapid maxillary expansion (RME) on soft tissue with stereophotogrammetry.
