Effects of twin-block appliance on the anatomy of pharyngeal airway passage (PAP) in class II malocclusion subjects
BACKGROUND The use of functional appliances for the correction of retrognathic mandible is very common in orthodontics. Similar appliances known as oral appliances are also frequently used in adults for the treatment of mild to moderate obstructive sleep apnea (OSA). Many studies have reported improvement of pharyngeal airway passage (PAP) dimensions following functional appliance therapy in ch...
متن کاملEffect of Clark's twin-block appliance (CTB) and non-extraction fixed mechano-therapy on the pharyngeal dimensions of growing children
INTRODUCTION Narrow airway dimensions due to mandibular deficiency can predispose an individual to severe respiratory distress. Hence, treatment with mandibular advancement devices at an early age might help improving the pharyngeal passage and reduce the risk of respiratory difficulties. Therefore, the aim of the current study was to evaluate the mean changes in the pharyngeal dimensions of ch...
متن کاملEarly correction of unilateral scissor bite using transforce appliance and modified twin block appliance
Early treatment of scissor bite has been advocated mainly to prevent function jaw shift that can eventually lead to permanent skeletal asymmetry and temporomandibular joint pathosis. Although unilateral scissor bite is more common, most of the times, bilateral mandibular expansion is indicated. Lingual transforce appliance can be useful in such cases. This article presents a patient with unilat...
متن کاملTreatment of Class II div 1 malocclusion with quadri block-a modified fixed twin block appliance
In growing patients. Class II malocclusion can be corrected by various modalities. Among all methods, functional appliances bring about better facial esthetics and functional harmony. Twin block is a most common among all functional appliances used to the correct skeletal discrepancy in growing individuals.1−4 A crowded dental arches necessities an additional prefunctional orthodontics to align...
متن کاملMechanical effects of pharyngeal constrictor activation on pharyngeal airway function.
The mechanical effects of pharyngeal constrictor (PC) muscle activation on pharyngeal airway function were determined in 20 decerebrate, tracheotomized cats. In 10 cats, a high-compliance balloon attached to a pressure transducer was partially inflated to just occlude the pharyngeal airway. During progressive hyperoxic hypercapnia, changes in pharyngeal balloon pressure were directly related to...
