Nano Coated Orthodontic Miniscrews for en Mass Retraction of the Upper Arch

study will be directed to evaluate silver-hydroxyapatite nano-coated versus uncoated orthodontic miniscrews for en masse retraction of the upper anterior segment.

Evaluation of the Biomechanical Response of Orthodontic Tooth Movement to Clear Aligner vs Fixed Orthodontic Appliance

Abstract Background: Orthodontic tooth movement (OTM) is mediated by biologic responses of the periodontal ligament (PDL) and alveolar bone to applied mechanical forces, involving release of inflammatory mediators such as interleukin-1β (IL-1β) and prostaglandin E2 (PGE2) that promote osteoclast activation and bone remodeling. Intraoral biomarkers in gingival crevicular fluid (GCF) reflect these tissue changes and can be used to monitor inflammatory and metabolic responses during treatment. Digital technologies, including intraoral scanning and 3D superimposition, allow precise quantification of tooth movement over time. Objective: This prospective, randomized comparative clinical study aims to compare the biological and mechanical responses of orthodontic tooth movement in patients treated with clear aligners versus conventional fixed appliances. Methods: Twenty adult patients (aged 18-25 years) with mild dental crowding will be randomly assigned to either a fixed appliance group (n=10) or a clear aligner group (n=10). Baseline and follow-up GCF samples will be collected to quantify IL-1β and PGE2 using enzyme-linked immunosorbent assay (ELISA). Tooth mobility will be assessed using Periotest analysis, and 3D digital models obtained from intraoral scans will be superimposed to measure the amount of tooth movement over time. Secondary outcomes include clinical measures of mobility and patient-reported pain. Expected Outcomes: It is anticipated that both treatment modalities will induce measurable increases in inflammatory biomarkers and tooth movement; however, differences in the magnitude and temporal patterns of IL-1β, PGE2, tooth mobility, and 3D-quantified displacement are expected due to the continuous forces of fixed appliances versus intermittent forces of aligners. Previous studies have shown that GCF cytokine levels rise with orthodontic force application in both aligner and fixed appliance treatments, with some variations between groups. Conclusion: This study will provide new clinical evidence comparing biological mediator profiles and mechanical outcomes between clear aligners and fixed orthodontic appliances, improving understanding of tissue responses and informing clinical decision-making in contemporary orthodontic practice

Clinical Trial to Assess the Efficacy of Reducing the Aligners' Wear Protocol

The hypothesis of this project is that replacing the current 7-day wear protocol with a 3-day wear protocol, while integrating less tooth movement per aligner (reduce the amount of activation per aligner) may produce more consistent and continues orthodontic forces, therefore, increase the predictability, accuracy and outcomes achieved for various types of tooth movements and enhance the rate of tooth movement with the Invisalign system

Clinical Evaluation of Local Calcitriol Delivery on Maxillary Canine Retraction

This study will evaluate the effect of locally applied Calcitriol on dental and skeletal changes during upper canine retraction. It is a split-mouth randomized clinical trial, where Calcitriol will be locally applied on one side of the maxilla, and the other side will serve as control.

Effect of MOPs During Orthodontic Movement in Periodontitis Patients

Micro-osteoperforations (MOPs) cause cortical bone injuries and consequently increase the expression of inflammatory mediators, allowing for increased bone and periodontal ligament remodeling associated with orthodontic movement. It remains unclear the effect of orthodontic intrusion combined with MOPs application on teeth with reduced periodontium. The general objective will be to determine the efficacy of MOPs during orthodontic tooth movement (OTM) in terms of periodontal and orthodontic outcomes in stage IV periodontitis patients, case type 2 with pathological tooth migration (PTM), characterized the presence of at least one flared tooth of the upper-anterior sextant with an intrabony defect (intrabony component \<5mm)
