Filter by:study will be directed to evaluate two approaches of micro-osteoperforations during maxillary molar distalization.
This clinical study will be directed to compare the effect of presence or absence of third molar on distalization of the upper posterior segment by using carriere motion appliance
Several methods aiming at the acceleration of orthodontic tooth movement have been proposed, including low-level laser therapy (LLLT), which showed promising results. However, the frequency of patient recall has been one of its major drawbacks.
Patients with skeletal Class II malocclusion due to mandibular retrognathism will be recruited and randomly allocated to three equal groups. first group will be treated by pushing orthopedic force mechanics, second group will be treated by pulling orthopedic force mechanics, and third group will be observed for 9 months to detect the natural growth changes. Skeletal changes will be evaluated and the treatment changes will be compared with the natural growth changes. The study hypothesis is that use of direct bimaxillary miniplate anchorage in conjunction with fixed functional appliance (pushing orthopedic force) or closed coil spring (pulling orthopedic force) will induce statistically significant skeletal mandibular growth in comparison to natural mandibular growth changes.
When there is space present between our teeth orthodontically we have the ability to close them through many methods. Using braces as our treatment modality this study will be investigating how efficient a new orthodontic wire is in closing tooth space. This new material is trade-named GUMMETAL and claims to have many benefits to treating patients orthodontically. We will be exploring its efficiency in space closure compared to an industry standard (stainless steel). We predict that the stainless-steel orthodontic wire will be more efficient at space closure than the new GUMMETAL wires.
Class II malocclusion with excessive overjet is one of the most common malocclusions among children and adolescents. The overall goal of the project is to analyze orthodontic treatment of Class II malocclusion with excessive overjet when the treatment is started in different ages and treated with removable and/or fixed appliance. Treatment initiated before the age of eleven is performed with a removable functional appliance, Headgear Activator (HGA). Treatment starting in early adolescence is performed with fixed orthodontic appliance (FA). The hypotheses are: - Treatment with HGA at the age of nine or eleven is effective. No spontaneous correction of the malocclusion is expected in the untreated control group. - Patient experience, treatment effect and cost-effectiveness are equivalent whether the treatment with HGA is initiated at the age of nine or eleven. - Treatment results, patient experience and treatment- and cost-effectiveness are equivalent whether treatment is initiated early with HGA or initiated in early adolescence with FA. - The treatment of Class II malocclusion with excessive overjet renders long-term treatment stability and patient satisfaction.
The main objective of this study is to quantify the distal movement of maxillary central incisors and molars achieved with infrazygomatic miniscrews in comparison with zygomatic miniplate anchorage.
The patients who applied to the hospital for orthodontic treatment were asked various questions to evaluate their oral health related quality of life, malocclusions and self reported temporomandibular joint problems.
OrthoPulse is a device that uses near-infrared light therapy in order to decrease orthodontic treatment time. The aim of this study is to evaluate OrthoPulse products modified with extended arrays, OrthoPulse 2.0 and OrthoPulse 2.1, and to assess their clinical effectiveness.
The purpose of this study is to assess the performance of the EXD-959 self-ligating ceramic bracket system using EXD 961 instruments in the treatment of orthodontic malocclusion. The information gained in this study and other studies will be used to evaluate the clinical performance of the bracket system during orthodontic treatment and to substantiate marketing claims for the bracket system, open/close instrument and de-bonding instrument.
