Moving device and method for depressing overlong maxillary posterior teeth

Abstract

The invention discloses a moving device and method for depressing overlong maxillary posterior teeth. The device comprises an occlusion bracket, a clamping ring, an artificial tooth part and a base plate. The moving device is beneficial for supporting an implant with good osseointegration and anteroposterior natural healthy teeth at the gap side. A patient can control occlusal force as main depressing force, and the occlusal force is controllable biological force. A resin artificial tooth plane on the lowering device is gradually adjusted to be higher to obtain a good lowering effect.

Description

technical field [0001] The invention relates to a movable device and method for depressing overlong posterior teeth, in particular to a movable device and method for depressing excessively long maxillary posterior teeth. Background technique [0002] After the loss of the mandibular posterior teeth, the maxillary posterior teeth often droop significantly over time. Insufficient jaw spacing often affects the restoration of the mandibular missing teeth and affects the patient's physiological functions such as chewing, which in turn leads to the patient's unilateral chewing and facial deviation. and physical and mental health. [0003] There are usually two methods to obtain normal occlusal space for the overlong maxillary posterior teeth: one is to use pulp inactivation for the overlong posterior teeth, after the root canal treatment is completed, part of the clinical crown is removed, and the full crown is restored to return to normal The occlusal plane can improve the prope...

AI Technical Summary

Problems solved by technology

However, this method reduces the clinical height of the maxillary overlong posterior teeth, reduces the strength of the full crown restoration, and has a significant impact on the long-term stability of the restoration.

Another method is to depress the overlong maxillary posterior teeth through orthodontics. The conventional orthodontic treatment takes a long time, and there are brackets and arch wires in the mouth, and there are many devices; it has obvious impact on the life and study of adults. impact, increasing the difficulty of oral hygiene maintenance

At present, with the development of implant technology, micro-implantation screws are mostly implanted on the buccal and lingual side of the maxillary posterior teeth, and the long posterior teeth are depressed by the anchorage of the implant screws and the continuous upward traction of the rubber band on the tooth surface, and the clinical treatment time is significantly longer. Shortening, lowering the efficiency is higher, but the treatment requires the implantation of micro-screws, and there are many traction devices, which may easily cause food residues to stay, which is not conducive to the maintenance of oral hygiene. If the patient has osteoporosis, the implant anchorage is easy to fall off and traction fail
