Miniscrew anchorage
I read the case report entitled “Distalization of the maxillary and mandibular dentitions with miniscrew anchorage in a patient with moderate Class I bimaxillary dentoalveolar protrusion” (Chen G, Teng F,…
How ideas are spread and used
About 100 years ago, new ideas were spread mainly by newspapers and other forms of print media. At the dawn of the 20th century, thousands of newspapers were published in the…
Distalization of the mandibular dentition with a ramal plate for skeletal Class III malocclusion correction
The retromolar fossa is an anatomically suitable skeletal anchorage site. The aim of this report was to introduce a novel appliance for the correction of skeletal Class III malocclusions with…
Biomechanical effects of maxillary expansion on a patient with cleft palate: A finite element analysis
Introduction The aims of this study were to evaluate the effects of rapid palatal expansion on the craniofacial skeleton of a patient with unilateral cleft lip and palate (UCLP) and…
Miniscrew-assisted slow expansion of mature rabbit sutures
Introduction In this study, we experimentally evaluated whether complex, mature sutures can be separated using skeletal anchorage and light, continuous forces. Methods Twelve adult, 8- to 9-month-old female New Zealand…
Rescue therapy with orthodontic traction to manage severely impacted mandibular second molars and to restore an alveolar bone defect
This case report describes the successful treatment of severely impacted mandibular second molars with severe apical root resorption of the mandibular first molars. The vertically impacted second molars were orthodontically moved (using…
Relationships between soft tissues in a posed smile and vertical cephalometric skeletal measurements
Introduction The purposes of this study were to measure the 3-dimensional parameters of the posed smile and to see whether there are any correlations with vertical cephalometric skeletal measurements. Methods…
Alteration of palatine ruga pattern in subjects with oligodontia: A pilot study
Introduction The aim of this study was to compare the palatal ruga patterns in subjects with oligodontia and normal tooth numbers. Methods An observational investigation was conducted by using maxillary…
Management of severely impacted mandibular canines and congenitally missing mandibular premolars with protraction of autotransplanted maxillary premolar
Transmigrated mandibular canines increase the treatment complexity in terms of both anchorage and biomechanical planning. Additionally, a Class II malocclusion with a deep overbite and associated dental anomalies such as…
Recognizing and correcting developing malocclusions: A problem-oriented approach to orthodontics
This textbook deals pragmatically with mixed dentition treatment, looks squarely at 2 phases of treatment, and helps the reader to understand what can be done. Nine authors from around the…
Landmark errors on posteroanterior cephalograms
Introduction It is important to reduce the method errors when evaluating posteroanterior cephalograms to see either small deviations from normal or transverse changes caused by orthodontic treatment. The aim of…
Analysis of covariance, Part 2
In the previous article I used an example comparing residual tooth irregularity after 6 months in 2 patient groups treated with different nickel-titanium wires. I discussed the adjustment of the analysis…
Statistical shape analysis-based determination of optimal midsagittal reference plane for evaluation of facial asymmetry
Introduction The purpose of this study was to determine, by statistical shape analysis of original and mirrored skeletal landmarks, the optimal landmark-based midsagittal reference plane for evaluation of facial asymmetry. Methods…
Learned intermediary
The facts of Watts v Medicis Pharmaceutical Corp ., No. CV-15-0065-PR (Ariz. Sup. Ct. 2016), are straightforward. The plaintiff had acne, received a prescription for Solodyn (minocycline), and received some…
Quantitative and qualitative assessment of anchorage loss during en-masse retraction with indirectly loaded miniscrews in patients with bimaxillary protrusion
Introduction This study provides vital insight in assessing anchorage loss when miniscrews are indirectly loaded. Methods The study sample comprised 18 patients with bimaxillary protrusion (14 girls, 4 boys; mean…
Impact of dentofacial development on early mandibular incisor crowding
Introduction In this retrospective longitudinal study, we evaluated the influence of dentofacial development on mandibular incisor crowding from the early mixed dentition (T1) to the early permanent dentition (T2). Methods…
Genetic and clinical risk factors of root resorption associated with orthodontic treatment
Introduction External apical root resorption (EARR) is a common complication in orthodontic treatment. Despite many studies on EARR, great controversies remain with regard to its risk factors. The objective of…
Treatment comfort, time perception, and preference for conventional and digital impression techniques: A comparative study in young patients
Introduction The aim of this crossover study was to assess perceptions and preferences for impression techniques in young orthodontic patients receiving alginate and 2 different digital impressions. Methods Thirty-eight subjects aged…
Comparing orthodontic bond failures of light-cured composite resin with chemical-cured composite resin: A 12-month clinical trial
Introduction In this clinical trial, we evaluated and compared bond failure rates of light-cured composite resin vs chemical-cured composite resin for 12 months. Methods Twenty-two subjects (356 stainless steel brackets) were…
Congenital and acquired mandibular asymmetry: Mapping growth and remodeling in 3 dimensions
Introduction Disordered craniofacial development frequently results in definitive facial asymmetries that can significantly impact a person’s social and functional well-being. The mandible plays a prominent role in defining facial symmetry…
