Clear Aligners With Two Different Change Schedules vs Traditional Braces for People With Crowded Lower Front Teeth

The goal of this clinical trial was to compare two clear aligner treatment plans with traditional braces for treating crowded lower front teeth in adults. Clear aligners were removable plastic trays. Traditional braces were metal brackets and wires. The main questions the study aimed to answer were: How fast did the teeth move? How long did treatment take? How much pain did participants feel? Researchers studied 21 adults aged 18 to 40 years. The adults had mild to moderate crowding of the lower front teeth. They did not have teeth removed for treatment. Researchers assigned participants by chance to one of three groups: Aligner I: clear aligners that moved teeth 0.25 mm per step. Aligner II: clear aligners that moved teeth 0.35 mm per step. Control: traditional braces. Participants: Wore clear aligners for 22 hours a day and changed to a new aligner every 2 weeks, or wore traditional braces that were adjusted every month. Visited the clinic for checkups, tooth scans, and pain checks. Were treated for up to 20 weeks. Researchers measured crowding with a score that showed how crooked the lower front teeth were. They recorded how many weeks treatment took. They asked participants to rate pain on a 0 to 10 scale. A score of 0 meant no pain. A score of 10 meant the worst pain. Researchers found that all three treatments straightened the teeth. Traditional braces worked fastest. The typical participant in the braces group finished in 10 weeks. The typical participant in Aligner II finished in 12 weeks. The typical participant in Aligner I finished in 16 weeks. Pain changed over time in all groups. Clear aligners were not always more comfortable than braces. At weeks 8 and 10, both aligner groups reported more pain than the braces group.

Exploration of the Utility of Dental-dedicated MRI for Dentistry

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.

The primary aim of the current study was to estimate the validity, reliability, and repeatability of LII measurements

Bone Level Changes Using Clear Aligners Compared to Fixed Appliances in Non-Extraction Treatment of Adults

This study compares two common ways of straightening teeth in adults who have mild-to-moderate crowding of the lower front teeth and do not need any teeth removed: clear aligners and traditional fixed braces. The main aim is to find out whether the two methods differ in how they affect the bone that surrounds the teeth. Using three-dimensional X-ray scans (cone-beam CT) and digital models of the teeth taken before and during treatment, the researchers measure the level and thickness of the bone around the lower front teeth, the tilt (inclination) of the lower front teeth, and how quickly the crowding is corrected. Adults are randomly assigned to receive either clear aligners or fixed braces, and the same measurements are compared between the two groups over about six months.

A Study to Evaluate the Relationship Between Two Bracket System and Their Contribution to Initial Alignment of Maxillary Anteriors - De Crowding, Smile Arc Protection.

The goal of this clinical trial is to compare the two orthodontic bracket systems namely MBT and the Pitts21 for maxillary anterior decrowding, initial alignment as well as the smile arc correction in 6 month period.

Bracket Positioning Techniques and Quality of Orthodontic Finishing

This three-arm randomized clinical trial compares three orthodontic bracket positioning techniques - Smile Arc Protection (SAP), Smile Arc and Marginal Ridge Approach (SAMRA), and the McLaughlin-Bennett-Trevisi (MBT) bracket placement chart (control) - in young patients with Angle Class I malocclusion and mild-to-moderate crowding treated non-extraction. The primary aim is to determine which technique yields the highest quality of orthodontic finishing, measured with the American Board of Orthodontics Objective Grading System (ABO-OGS). Secondary aims compare anterior tooth tip and torque (assessed by CBCT) and mini-esthetic smile parameters (gingival display, incisal display, buccal corridor, and smile arc, assessed on standardized posed-smile photographs) among the three techniques.

Orthodontic Treatment Outcomes of Self Ligating System Compared to Clear Aligner System

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 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

Clinical Performance of Direct-Printed Versus Thermoformed Aligners

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.

Treatment Outcome of Elastomeric and Nickel-Titanium Separators in Tooth Separation

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.

Evaluating the Clinical Efficacy of Collagen Scaffold (Ossix VOLUMAX) With Piezo-Surgical Decortication in Enhancing Orthodontic Treatment Outcomes: A Randomized Controlled Trial

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.
