Maxillary protraction oral device

Abstract

The invention discloses a maxillary protraction oral device. The maxillary protraction oral device comprises a base support, fixing devices, protraction hooks and jaw pads, the base support comprisesa front part and side parts, the side parts are arranged at the two ends of the front part, one ends of the fixing devices are fixedly connected to the side parts of the base support, the number of the protraction hooks is two, one ends of the protraction hooks are fixed to the front part of the base support, the jaw pads are fixed on the end surface of the base support, hooking parts are arrangedat the other ends of the protraction hooks and are located in front of the front part, each hook part is composed of three hook bodies, and the bend directions of every two adjacent hook bodies are opposite. The maxillary protraction oral device has the advantages that the jaw pads are arranged, so that upper teeth and lower teeth can be effectively prevented from being occluded together, and therefore the height is increased, malocclusion of the teeth can be eliminated, the process of applying force to an appliance is facilitated, and the movement process of a maxillary bone is not hindered;and the protraction hooks are arranged, so that rubber bands can be conveniently hooked on the protraction hooks and can be adjusted to be matched with the hook bodies in different directions according to the malocclusion and malformation direction, and therefore the stress direction of the protraction hooks can be adjusted conveniently, the purpose of correcting is achieved, and the use and theoperation are convenient.

Description

technical field [0001] The invention belongs to a medical device for dental correction, in particular to a front traction intraoral device. Background technique [0002] According to the classification of malocclusions, in Angle III malocclusions, in addition to the overgrowth of the mandible, the large and poor growth of the maxilla is also an important reason. To correct this type of malocclusion, the cause must first be removed, and it should be corrected with orthodontic appliances. Existing orthodontic appliances include functional orthopedic methods such as mandibular lip stop, maxillary lip stop movable appliance, muscle activator, to block and correct malocclusion. However, the above-mentioned appliances have their own limitations in indications. The mandibular lip needs molar clinical crown height, which is not suitable for deciduous dentition; the lip wire of the upper lip movable appliance cannot be adjusted vertically, and the functional adjustment is limited; ...
