Physical properties of root cementum: Part 23. Effects of 2 or 3 weekly reactivated continuous or intermittent orthodontic forces on root resorption and tooth movement: A microcomputed tomography study Banu…
Radiographic study of delayed tooth development in patients with dental agenesis
Introduction The aims of this study were to compare the radiographic development of permanent teeth in a group of children affected by dental agenesis with an unaffected control group and…
Three-dimensional finite element analysis of strength, stability, and stress distribution in orthodontic anchorage: A conical, self-drilling miniscrew implant system
Introduction The aims of this study were to analyze the stress distribution and displacement patterns that develop in an orthodontic miniscrew implant and its surrounding osseous structures for 2 implant…
A practical and effective method to increase the capacity of screws used for palatal disjunction
In clinical situations involving accentuated atresia in the maxillary arch, palatal disjunction is called for. This treatment often requires an appliance change to achieve the desired movement. The aim of…
Long-term stability of conservative orthodontic treatment in a patient with rheumatoid arthritis and severe condylar resorption
Rheumatoid arthritis is a chronic inflammatory condition that can result in progressive destruction of the articular surfaces of the joints, including the temporomandibular joint. The purpose of this article is…
Efficacy of low-intensity laser therapy in reducing treatment time and orthodontic pain: A clinical investigation
Introduction The long duration of orthodontic treatment is a major concern for patients. A noninvasive method of accelerating tooth movement in a physiologic manner is needed. The aim of this…
Interactive distance learning for orthodontic residents: Utilization and acceptability
Introduction Sharing resources through distance education has been proposed as 1 way to deal with a lack of full-time faculty in orthodontic residency programs. To keep distance education for orthodontic…
Orthodontic treatment for a patient with a unilateral cleft lip and palate and congenitally missing maxillary lateral incisors and left second premolar
Treatment of a patient with a cleft lip and palate can be challenging. A woman, aged 26 years 8 months, was referred for orthodontic evaluation of her anterior crossbite. She…
Improvement of nasal airway ventilation after rapid maxillary expansion evaluated with computational fluid dynamics
Introduction Rapid maxillary expansion is known to improve nasal airway ventilation. However, it is difficult to precisely evaluate this improvement with conventional methods. The purpose of this longitudinal study was…
Stress and displacement between maxillary protraction with miniplates placed at the infrazygomatic crest and the lateral nasal wall: A 3-dimensional finite element analysis
Introduction The purpose of this study was to compare the pattern and amount of stress and displacement between maxillary protraction with miniplates placed at the infrazygomatic crest and the lateral…
Effects of thread depth, taper shape, and taper length on the mechanical properties of mini-implants
Introduction The primary stability of a mini-implant is critical, since most orthodontic mini-implant failures occur at an early stage. As orthodontic mini-implants have restrictions in diameter and length, an optimal…
Blinding or masking
“Masking” (or “blinding”) refers to the steps taken to ensure that all persons involved in a trial are unaware of the type of treatment that each participant receives. In general,…
What to say given what was said
A reader from Connecticut wrote with the following questions. A parent calls last minute to reschedule their child’s after school appointment, demands to be seen at the same time on…
Development of white spot lesions during orthodontic treatment: Perceptions of patients, parents, orthodontists, and general dentists
Introduction Despite the many advances to improve the practice of orthodontics, white spot lesions, or decalcifications, remain a common complication in patients with poor oral hygiene. The purpose of this…
Perceived vs measured forces of interarch elastics
Introduction Orthodontists depend on perceptions derived from education and clinical experience to judge the optimal forces in patient treatment. The purpose of this study was to survey practicing orthodontists to…
Viscoelastic properties of elastomeric chains: An investigation of pigment and manufacturing effects
Introduction Orthodontic elastomeric chains are commercially available in various colors from many manufacturers. In this study, we investigated the viscoelastic properties of elastomeric chains using dynamic mechanical analysis to perform…
Comparison of the orthodontic load systems created with elastomeric power chain to close extraction spaces on different rectangular archwires
Introduction The 3-dimensional load system (forces and moments) was quantified at the canine bracket during space closure with sliding mechanics with elastomeric chain on dry and wet stainless steel and…
Correction of collapsed occlusion with degenerative joint disease focused on the mandibular arch and timely relocation of a miniplate
This report describes a novel concept of 3-dimensional tooth movement by using biocreative therapy to provide unrestricted distal movement of the full mandibular dentition. The patient was a 26-year-old Korean…
