CONTEXT: Assessing and monitoring treatment quality within graduate courses are vital for maintaining high standards and addressing areas needing improvement. In this study, we evaluated the treatment quality delivered by measuring the total scores obtained from the comprehensive clinical assessment (CCA) index and the objective grading system (OGS) index. AIMS: This study aimed to evaluate the quality of orthodontic treatments administered by graduate students by using the CCA index and OGS index. SETTINGS AND DESIGN: The research was carried out at the Orthodontic Department of Mashhad School of Dentistry, focusing on a cross-sectional analysis of orthodontic treatments administered by graduate students. METHODS AND MATERIAL: The study randomly selected 36 cases from the department's archives and evaluated them through pre- and post-treatment analyses, including radiographs, photographs, and dental casts. The evaluation employed the CCA and the OGS indices. STATISTICAL ANALYSIS USED: Data analysis was performed using the Spearman and Mann-Whitney tests. RESULTS: The CCA correlated with the patient's age and gender and was statistically significant (P = 0.007 and P = 0.010, respectively). The CCA index was substantially associated with treatment duration (P = 0.032 a). There was no significant relationship between OGS and CCA (P = 0.223). The mean of post-treatment OGS was 18.97. All criteria of OGS and the overall score were improved significantly (P < 0.001). CONCLUSIONS: The results of this study suggested that orthodontic treatment results provided by the investigated program have high scores and meet high standards of the CCA and OGS indices.

OBJECTIVE: To evaluate and compare the skeletal and dental treatment effects of Class II malocclusion cases using skeletally anchored Forsus (miniscrew-anchored FRD or miniplate-anchored FRD), with conventional Forsus FRD. MATERIALS AND METHODS: Unrestricted electronic search of six databases and additional manual searches were performed up to July 2023. Randomized controlled trials having one treatment arm with skeletal anchored Forsus FRD in treatment of Class II malocclusion and another matched treatment group treated with conventional Forsus FRD were included in this review. Risk of bias assessment was performed using Cochrane's Risk of Bias Tool. No restrictions were set concerning treatment duration, or the cephalometric analysis used. Skeletal and dentoalveolar outcomes data were extracted by two authors independently. RESULTS: Three studies using miniscrews as means of skeletal anchorage were evaluated and qualified for the final review and meta-analysis. Three other studies using miniplates were considered in the systematic review but were not qualified for a meta-analysis. The data gathered from the miniscrews anchored FRD papers included a total of 93 Class II patients (46 treated with miniscrew-anchored Forsus FRD, 47 treated with conventional Forsus FRD). The meta-analysis showed a statistically significant reduction in the SNA angle in favor of miniscrew-anchored Forsus FRD (mean difference: −0.26, CI: −0.50 to −0.02), a nonsignificant difference in the SNB (mean difference: 0.17, CI: -0.06 to 0.39), a statistically significant increase in the SN–MP angle in favor of miniscrew-anchored Forsus FRD (mean difference: 0.53, CI: 0.06–1.00)—a statistically significant reduction in the L1-MP angle in favor of miniscrew-anchored Forsus FRD (mean difference: −2.12, CI: −4.96 to −2.12). Data from miniplate-anchored FRD included 31 Class II patients treated with mini plate anchored FRD. Although meta-analysis was not applicable to these studies, lower incisor inclination was observed to be less. CONCLUSIONS: Based on the existing evidence, the use of skeletal anchorage could not enhance forward mandibular growth. However, miniscrew-anchored Forsus FRD could minimize mandibular incisor protrusion while miniplates could even retract the mandibular incisor position with a headgear effect on the maxilla.

Background/Objectives: The orthodontic treatment of posterior crossbite using appliances for gradual maxillary expansion is crucial to ensure proper transversal jaw relationships as much as occlusal functionality. The aim of this study was to analyze forces and torques generated by different appliances for maxillary expansion. Methods: Measurements were conducted for the Wilson® 3D® Quadhelix (WQH) and Wilson® 3D® Multi-Action Palatal Appliance (WPA) across various sizes and compared to the Remanium® Quadhelix (RQH). Activations were set to 8 mm for the WQH and RQH and 6 and 8 mm for the WPA. Rotations and root torque were simulated via an activation of 10° for arches. A total of eight test series were conducted. Results: The WPA displayed the highest force and torque values for all movements, far surpassing recommended guideline values (expansion 8.5–>15.0 N/46.3–86.5 Nmm, rotation 3.1–6.1 N/40.7–61.4 Nmm, torque 3.9–5.1 N/22.4–29.7 Nmm), and the WQH displayed the lowest values (expansion 2.7–12.6 N/11.1–39.6 Nmm, rotation 0.1–1.7 N/23.0–32.2 Nmm, torque 0.9–2.9 N/3.4–10.5 Nmm). Appliances with the smallest transverse dimensions exhibited the highest force and torque maxima. Conclusions: This study underscores the importance of understanding biomechanical principles in orthodontics for minimizing unintended tooth movements, providing detailed insights into the force systems of appliances acting in the transverse plane, and establishing a foundation for future clinical investigations to validate these in vitro findings.

The article explores the growing popularity of clear aligners in orthodontic care, driven by their effectiveness and aesthetic appeal. Topics discussed include the rising cost of orthodontic treatment, the appeal of direct-to-consumer aligners for affordability, and the trade-offs between cost and treatment quality.
