Summary: This study evaluated clinical variables affecting attachment shape accuracy, finding that PET-G templates had greater precision and were recommended for use. Additionally, there were significant differences between high-viscosity and low-viscosity composite resins when pressure-curing.

Summary: The study evaluated the effects of orthodontic treatment with aligners and conventional fixed appliances on speech production. Changes in speech production were observed at the start of treatment in patients with aligners, but both groups reported significant speech difficulties immediately after appliance insertion. Over time, speech production improved in both groups.

Summary: This study demonstrates that seemingly minor experimental variations, even under normal baseline conditions, can have a significant impact on epigenome outcome measures and data interpretation. It highlights the importance of strict adherence to protocols in epigenetic studies, as protocol-sensitive changes may confound experimental results amongst naive animals.

Summary: This study verified that the orthodontic force in transparent orthodontic appliances can be estimated and visualized using near infrared 2D birefringence measurement. This information is crucial for meeting the aesthetic demands of patients and adjusting the aligners.

Summary: This retrospective real-world study evaluated the outcomes of clear aligner treatment (CAT) and patient demographics of patients seeking orthodontic re-treatment who had previously received orthodontic treatment in childhood or adolescence. Data from 2080 patients in Germany who completed their CAT between June 1st and June 30th, 2022 were analyzed. The study highlights the need for orthodontists and dentists to provide adequate information to patients about long-term retention and decision-making for orthodontic treatment, especially for re-treatment.

Summary: This systematic review and meta-analysis examines the impact of cancer and its treatment on orthodontic treatment success. It finds a strong association between radiotherapy, antineoplastic drugs, and reduced success in orthodontic treatment, especially in older populations. The review underscores the importance of considering cancer therapies in orthodontic planning to optimize results and minimize complications.

Summary: This study evaluated the trends and perspectives among orthodontists regarding the usage of clear aligner therapy in the mixed dentition, including indications, compliance, oral hygiene, and other factors. The results showed that the use of clear aligners in mixed dentition was less common compared to fixed appliances, but most orthodontists predicted an increase in future use of clear aligners. The study also found that the number of patients treated with clear aligners in mixed dentition was significantly lower than the total number of patients, and there were limited indications for clear aligners compared to fixed appliances.

Summary: This study evaluated the effect of different aligner materials and attachment shapes on the movement of a single tooth during orthodontic therapy. The results showed that while the BENQ group had smaller changes in the long axis angle of the canine, the movement of the canine in this group was mainly bodily, as opposed to the tipping movement seen in the BIOSTAR and TPU groups. Attachment shape or size had minimal influence on the bodily movement of the tooth, suggesting that high modulus materials may be suitable for clinical applications.

Summary: The present study aimed to assess the topographical and optical characteristics of thermoplastic dental appliance materials in relation to water sorption. The study found that surface roughness increased and optical characteristics showed some changes after water uptake. Additionally, an increase in inhomogeneity in the network structure of particles was observed at the nano-level. The evaluation of water uptake and desiccation stages showed a significant increase in the specific weight of the materials within the first 12 hours.

Summary: This study developed a thermoforming film loaded with hydrogen peroxide as a clear aligner and evaluated its bleaching effect on teeth and its influence on shear bonding strength. The results showed that the film effectively improved tooth color without affecting shear bonding strength.

Summary: This study investigates women's preferences for energy-efficient appliances in Pakistan and finds that place attachment and perceived behavioral control significantly influence their attitudes and intentions to purchase such appliances. However, personal norms and subjective norms are not significant factors. The study suggests that the prevailing patriarchal culture in Pakistan influences women's decision-making power regarding appliance purchases.

Summary: Comparing and analyzing the movement and rotation of teeth between a general attachment and an overhanging attachment, an effective design for the overhanging attachment is found to efficiently induce distal displacement of the central incisor while reducing crown tipping and preventing axial rotation. However, lingual inclination of the tooth cannot be prevented by aligners with or without attachments.

Summary: This study evaluated the initial retentive force and retention force after 2 years of simulated clinical use of a digitally designed ball attachment housing and compared it with a regular nylon ball attachment housing. The results showed that the CAD-CAM-PEEK attachment housing had higher retention forces compared to the conventional attachment with nylon rings, both initially and after long-term use.
