The loop regulating appliance

The K-loop molar distalizing appliance.

With the recent trend toward more non extraction treatment, several appliances have been advocated to distalize molars in the upper arch. Certain principles, as outlined by Burstone, must be borne in mind when designing such an appliance:

Self-regulating Neurons in the Sensorimotor Loop

Synaptic plasticity for recurrent neural networks is derived by introducing neurons as self-regulating units. These neurons have homeostatic properties for certain parameter domains. Depending on its underlying connectivity a neurocontroller endowed with the derived synaptic plasticity rule can generate a variety of different behaviors. The structure of these networks can be developed by evolut...

Molar distalization with a pendulum appliance K-loop combination.

SUMMARY The aim of this study was to evaluate the dentoalveolar effects of a pendulum appliance supported buccally by a K-loop, and to compare these with a cervical headgear (CHG) group. The records of 30 patients with skeletal Class I and dental Class II malocclusions were divided in to two groups: Patients in group 1 (seven females and eight males; mean age, 15.0 +/- 3.4 years) were treated w...

The two by four appliance: a versatile appliance.

The 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 compl...
