This study is to evaluate the validity of Ashley Howe's analysis for the prediction of the extraction treatment decision in orthodontic patients at the permanent dentition stage

The goal of this study is to evaluate and compare the clinical effectiveness of in-office directly 3D-printed clear aligners versus conventional multilayered thermoformed aligners. The main question it aims to answer is: Does the use of in-office direct-printed shape-memory aligners result in superior clinical effectiveness, compared to established multilayer thermoformed aligner systems? Researchers will compare a Direct-Printed Aligner (DPA) group using Senertek Clear-A V2 resin to a Thermoformed Aligner (TFA) group using Zendura FLX multilayer sheets to see if the additive manufacturing process improves clinical outcomes and patient satisfaction. Participants will: * Undergo initial records including intraoral digital scans, photos, and a panoramic radiograph for treatment planning. * Wear their assigned clear aligners (either direct-printed or thermoformed) for at least 22 hours per day, changing them every 7 days. * Attend follow-up appointments every 5 weeks.

This study is a multi-center, prospective, parallel-group randomized controlled trial designed to compare the orthodontic treatment outcomes of a passive self-ligating bracket system (Damon Ultima) versus a clear aligner system. The primary objective is to evaluate and compare the total orthodontic treatment duration between the two systems in patients with Angle Class I malocclusion and moderate crowding. Secondary objectives include assessing alignment efficiency, patient pain perception at multiple time intervals, dental arch dimension changes, root volume loss percentage, and overall treatment quality using the American Board of Orthodontics Objective Grading System (ABO-OGS).

This description observational research is comparative in design, that is comparing existing standard clinical dental images, not obtained in this study, to test (i.e., ddMRI) images. The standard clinical dental images consist of radiographs, such as bitewings, periapical, panoramic, cone-beam CT, and medical CT, as well medical MRIs of the temporomandibular joints (TMJ).The conceptualization of research questions, study designing, and interpretation of imaging data has and will involve content expertise in all ddMRI research.

Patients seeking fixed orthodontic treatment that requires band placement will be enrolled in this study. This trial aims to compare the efficiency of rectangular cross-section nickel-titanium separators with elastomeric separators in creating sufficient interdental space for orthodontic band placement. In addition, the impact of both separator types on pain perception and gingival health during a 3-day placement period will be evaluated. Participants will be allocated to two groups in a split-mouth design. On the experimental side, nickel-titanium separators will be used, while elastomeric separators will be used as the control on the other side. Outcomes will include separation efficacy, pain perception over time, gingival inflammation, analgesic consumption, and separator loss.

Recent advances in orthodontic treatment have explored various materials to enhance treatment efficacy, particularly focusing on collagen scaffolds. Collagen, being a primary component of the bone matrix, has garnered attention for its biocompatibility, cell adhesion, and osteoconductivity properties. Studies have shown that collagen scaffolds undergo natural degradation, mimicking biological processes, and play a significant role in tissue engineering (International Journal of Implant Dentistry, 2023). This aligns with the growing interest in minimally invasive methods that accelerate orthodontic treatment and improve tissue regeneration. In this context, the application of collagen scaffolds, such as Ossix VOLUMAX, in conjunction with piezo-surgical decortication, presents a novel approach. This study aims to build upon the existing knowledge, exploring the efficacy of collagen scaffolds in enhancing orthodontic treatment outcomes, especially in patients with specific dental conditions like a thin gingival phenotype and malocclusion. The study\'s hypothesis is grounded in the promising properties of collagen-based materials in dental and orthodontic applications, as evidenced by recent research in the field.
