NCT07500194
This randomized clinical trial aims to evaluate and compare the effectiveness of the Quad Helix (QH) appliance versus Rapid Maxillary Expanders (RME) in treating posterior cross-bite in Egyptian children during the mixed dentition stage. The study will also assess patient comfort and pain levels associated with each appliance.
NCT06994754
The goal of this clinical trial is to learn if the aligners can expand upper dental arch in patients with cleft lip and palate at age of 6-8 years old to correct their collapsid archs. The main questions it aims to answer are: Does aligners can achieve transverse dento-skeletal changes? Does aligners can achieve anteroposterior and vertical dento-skeletal changes? Participants will: Wear sequence of aligners (each for 10 days). Visit the clinic every month for checkups. 3D x-ray and intraoral scan will be taken after completion of the aligners set to evaluate the intervention.
NCT06227351
The aim of study is evaluation of accuracy of completely versus partially limiting computer generated surgical three-dimensional guides during placement of zygoma implants in patients with atrophic maxillae.
NCT06446687
This study aims to evaluate the quantity and quality of the native and the newly bone around dental implants that's simultaneously installed with sinus lifting
NCT06315348
Research Question While the reduction in treatment times and the patient satisfaction after periodontally accelerated osteogenic orthodontics (PAOO) are well sustained in the scientific literature, there is still controversy regarding if grafting leads to i) change of the periodontal phenotype and ii) greater stability of post-orthodontic treatment outcomes, highlighting the need of controlled clinical trials. Aims of the Project The aim of this randomized clinical trial (RCT) is to compare piezocision-assisted orthodontics, concomitant to soft tissue grafting (volume-stable collagen matrix), with piezocision-assisted orthodontics, concomitant to bone grafting with a xenograft and a native collagen membrane, in orthodontic non-growing patients. The primary aim will be to determine the impact of this surgical protocol on the hard and soft tissue changes occurring on the buccal aspect of the dentition. Secondary objectives will include the assessment of the comparative impact on treatment duration, rate of tooth movements, presence of root resorption, periodontal parameters, bone level changes and patient-reported outcome measures (PROMs) between the two groups.
NCT06009796
This study aims to evaluate the effects of dentoalveolar, dentoskeletal, nasal resistance, and airway changes by applying rapid palatal expansion appliances in patients with maxillary constriction and the post-pubertal growth spurt stage.
NCT05089396
The aim of this study will be directed to the assessment of dentoskeletal effects concomitant with skeletally anchored maxillary protraction in orthodontic skeletal Class III patients.
NCT03503448
This study evaluates 2 Techniques of Surgically Assisted Rapid Maxillary Expansion (SARME) in the treatment of maxillary transverse deficiency. Half of participants will undergo an osteotomy between the maxillary central incisors, while the other half will undergo an osteotomy between the maxillary lateral incisors and canines (bilateral osteotomies).
NCT00519415
A new appliance will be used to transfer the tongue force during its physiological activity to advance the nasomaxillary complex; this method will be compared with the traditional method which uses a Facemask appliance.
