Abstract
The invention discloses an extraoral force type mandibular molar intrusion appliance, which comprises a chin holder, connectors and jaw pads, wherein each connector comprises an upper cross rod, a vertical rod and a lower cross rod which are sequentially connected with one another; the chin holder and the jaw pad are connected with each other through at least two rows of connectors; at least two jaw pads are fixedly connected with the upper side ends of the upper cross rods of the connectors; the chin holder is fixedly connected with the lower side ends of the lower cross rods of the connectors; the connectors have elasticity; and the upper cross rods of the connectors and the chin holder are tensioned through elastic elements. The appliance is a removable and movable device, and is simple in structure, relatively low in cost, simple to operate, safe, reliable and non-invasive.
Description
Technical field
The present invention relates to a kind of mouth external force type lower molar and force down appliance.
Background technology
Molar intrusion is that a kind of important in Orthodontic Treatment rescues technology, be widely used in that labial teeth is opened, tooth closes and to extend rescuing of grinding one's teeth in sleep, in the therapeutic process of molar intrusion, one of difficulty that clinicist faces is exactly how when forcing down target and grinding one's teeth in sleep, and avoids the unwanted movement of other tooth as anchorage.
Summary of the invention
In view of the deficiency that background technology exists, technical problem to be solved by this invention is to provide a kind of mouth external force type lower molar and forces down appliance.This mouthful of external force type lower molar forces down that appliance structure is simple, cost is lower, and this appliance is the head that can pluck simultaneously, simple to operate, safe and reliable and non-invasive.
The present invention takes following technical scheme: a kind of mouth external force type lower molar forces down appliance, comprise chin holder, connector and jaw pad, described connector comprises the cross tube, montant and the sheer pole that connect successively, described chin holder is connected by least two row's connectors with jaw pad, at least two described jaw pads are fixedly connected on the upside of connector cross tube, described chin holder is fixedly connected on the lower side of connector sheer pole, described connector has elasticity, is strained between the cross tube of described connector and chin holder by elastic component.
In the present invention, this mouthful of external force type lower molar forces down the jaw face that the mouth external force acting on chin portion is delivered to lower molar by the ingenious connection of appliance by connector, lower molar is produced and forces down Orthodontic force, elastic component between utilization upper connector and chin holder is in mouth applied force, produce softer and lasting Orthodontic force, this appliance structure is simple, cost is lower, simple to operate, safe and reliable and non-invasive.
