Introduction: Orthognathic surgery, a well-established procedure for correcting significant skeletal imbalances, addresses both aesthetic and functional concerns. Traditionally, fixed orthodontic appliances have been preferred due to their effectiveness in managing dental movements and ensuring postoperative stability. However, the increasing demand for more aesthetic and comfortable options has led to the growing use of clear aligners, even in complex surgical cases. Although aligners...

Introduction: The purpose of this study was to evaluate the agreement between the predicted and the achieved tooth position planned by an orthodontic digital system. Methods: Digital models of the setup (Predicted) and the treated (Treated) groups of 23 subjects with Class I malocclusion were obtained. Digital models (Predicted and Treated) of each patient were superimposed, and referential geometric planes were constructed for linear and angular measurements: arch perimeter, arch depth,...

Objective: The aim of this study was to evaluate the effectiveness of four hygiene protocols for orthodontic mini-implants in reducing the subgingival bacterial load in the peri-implant sulcus. Methods: Thirty-nine healthy individuals who had fifty- nine as-received mini-implants (20 men, 19 women, 20 to 42 years old) were randomly distributed into four groups of hygiene protocols: mechanical hygiene (M); mechanical hygiene associated with 0.12% digluconate chlorhexidine (CHX), 0.03%...

Introduction: Fixed orthodontic appliances facilitate microbial adhesion and plaque accumulation. Although chlorhexidine has proven to be the most effective antiplaque and antigingivitis agent, it has several side effects. Objective: The present study aims to evaluate and compare the effectiveness of silver nanoparticles (SNP) and Chlorhexidine (CHX) mouthwash on reducing the microbial count and improving oral health during fixed orthodontic treatment. Trial design: 4-arm parallel,...

Introduction: Fixed orthodontic therapy is often accompanied by accumulation of plaque around the orthodontic brackets, which increases the number of periodontopathogenic bacteria. Objective: The objective of this study was to determine the changes in the subgingival microflora that occurred six months after the placement of a fixed orthodontic appliance. Methods: The study included 30 patients aged 13 to 35 years, in whom samples of subgingival plaque were taken before and six months after...

Objectives: This single-blinded randomized control trial aimed to assess the effect of Low-Intensity Pulsed Ultrasound (LIPUS) on the duration of alignment and leveling stage, and to assess patients’ pain and discomfort following the procedure. Material and methods: 30 participants (18-35 years) were recruited, of whom 22 were selected with Little’s Irregularity Index of 1-6mm following a non-extraction protocol, and were randomly allocated into two groups using a lottery method. The...

Introduction: Artificial intelligence (AI) has become a prominent focus in orthodontics. Objective: This study aimed to compare treatment plans generated by AI platforms (ChatGPT, Google Bard, Microsoft Bing) with those formulated by an experienced orthodontist. Methods: This observational cross-sectional pilot study aims to evaluate the effectiveness of AI-powered platforms in creating orthodontic treatment plans, using a clinical case treated by an experienced orthodontist as a benchmark. A...

Introduction: A wide variety of extra-alveolar orthodontic miniscrews are available. Objective: This study aims to describe and compare the design, and the topographical and mechanical properties of five distinct commercial brands of extra-alveolar miniscrews. Methods: Scanning electron microscopy (SEM), using 25×, 50×, 100×, and 200× photomicrographs, and in-vitro mechanical tests (driving torque, torsion, and pullout test) to compare extra- alveolar miniscrews (n=80, 2 mm x 12 mm) from...

Objective: This study aimed to evaluate the intra- and inter-examiner reproducibility of photographic records of the facial profile in Natural Head Position (NHP) and Oriented Position (OP) taken by four examiners (two orthodontists, one oral and maxillofacial surgeon, and one photography technician). Methods: Each professional captured two lateral photographs of 25 individuals during the first (T1) and second phases (T2), to assess the reproducibility of the technique and method error using...
