Key MethodThe 2 x 4 appliance comprises bonds on the maxillary incisors, bands on the first permanent maxillary molars and a continuous archwire. The appliance is used in the early mixed dentition for treatment of both anterior crossbites and alignment of ectopic incisors. Four cases using this appliance are presented. This appliance offers many advantages over alternative techniques as it provides complete control of anterior tooth position, is extremely well tolerated, requires no adjustment by the…Expand
Interceptive Correction of Anterior Crossbite Using Short-Span Wire-Fixed Orthodontic Appliance: A Report of Three Cases
TLDR
This sectional appliance provides an alternative method of correcting anterior crossbite of dental origin and offers many advantages compared to the use of removable appliances. Expand
Sectional fixed appliance therapy in the mixed dentition
TLDR
This paper discusses four case scenarios of malocclusion in the mixed dentition managed using sectional fixed therapy, and concludes that the sectionalFixed appliance is versatile, easy to use and well tolerated by patients. Expand
Diagnosis and Management of a Unilateral Posterior Open Bite Using a Temporary Anchorage Device (TAD): Case Report and Review of the Literature
  • B. Alyami

TLDR
This report describes the diagnosis and successful treatment of a unilateral posterior open bite in a 15-year-old Caucasian boy, who had ankylosis of left posterior teeth as the etiological factor of the POB. Expand
Failure of Eruption of First Permanent Molar Teeth: A Diagnostic Challenge
TLDR
A case where an initial presentation characteristic of mechanical failure of eruption (ankylosis) of a first permanent molar tooth was excluded following a period of monitoring, allowing spontaneous eruption of the tooth obviating the need for surgical intervention. Expand
The Timing of Orthodontic
TLDR
The current concepts of early treatment, both physiological and psychological, will be explored and the relevant indications and contraindications discussed. Expand
The use of 2x4 orthodontic appliance for interseptive treatment
TLDR
The corrections of malocclusion do not have to wait until the eruption of all permanent teeth, so the treatment time will be shorter compared to conventional orthodontic treatment. Expand
The timing of orthodontic treatment.
TLDR
The current concepts of early treatment, both physiological and psychological, will be explored and the relevant indications and contraindications discussed. Expand

Oligodontia is the congenital absence of six or more than six teeth in either permanent or primary dentition. Because of the missing teeth in these patient's esthetic, functional and psychologicalExpand
True orthodontic intrusion using three-piece intrusion arch for correcting excessive gingival exposure
The combination of proclined upper anteriors with high gingival exposure is challenging for the orthodontist. Correction of proclined upper anteriors sometimes leads to deepening of the bite and lossExpand
Shear bond strength differences of types of maxillary deciduous and permanent teeth used as anchor teeth.
TLDR
There were significant differences in shear bond strength among different permanent and deciduous tooth types, but deciduously teeth could be used as anchor teeth in orthodontic treatment with sectional edgewise appliances. Expand

The early treatment of posterior crossbites: a review of continuing controversies.
TLDR
A posterior crossbite may pose long-term risk through causing associated displacement in the mandibular path of closure and the current opinions on treatment of such a problem are reviewed. Expand

TLDR
The findings suggest that early orthodontic intervention is the norm, but practice characteristics affect treatment timing, and Orthodontists who have been in practice longer were more likely to treat temporomandibular joint sounds and deviations in opening. Expand

TLDR
It is concluded that there is little to be gained from precisely timing early treatment to specific age/maturity markers and that a favorable reduction in Class II skeletal problems can occur for patients in a broad range of skeletal severity and growth patterns. Expand

TLDR
Psychologic issues that should be considered in the decision to initiate orthodontics in the younger child or to wait until adolescence or later are examined, suggesting that younger children are good candidates for Phase I orthodentics, have high self-esteem and body-image, and expect orthodrontics to improve their lives.
