Description

Adjusting jaw pad for overlong molar

Technical Field

The utility model belongs to the oral cavity field, concretely relates to an adjustment jaw pad for overlength molar.

Background

The upper and lower molars are the main functional teeth in the oral cavity for performing the function of chewing. Early loss of molars often results from conditions such as periodontitis, apicitis, abnormal chewing habits, nocturnal molars, trauma, and the like. Due to long-term loss of antagonistic teeth, excessive eruption and extension of molars of the jaw often occur, so that the vertical space between the jaws is insufficient, normal implantation, fixation or movable denture repair cannot be performed, jaw interference is caused in the forward extension, lateral movement or backward movement, and jaw injury is caused. Particularly in maxillary molars. Because of the relatively low bone density in the maxillary molar region, patients with clinically common mandibular molar loss experience hyperextension of the corresponding maxillary molar.

At present, the following methods are often adopted to treat hyperelongation molar: crown amputation, orthodontic correction, subapical osteotomy and surgical removal. Crown amputation is a common clinical procedure. The molar is excessively extended, the normal occlusion curve and the enough restoration space cannot be recovered by simply adjusting the jaw, and the restoration space can be required only by crown cutting at the time, but the pulp vitality is sacrificed in this way. The patient needs to perform root canal treatment before cutting the crown, and the fracture resistance of the treated tooth is reduced. Orthodontic correction adopts the orthodontic mode of anchorage nail and leather chain to depress molar of excessive elongation at present, anchorage nail adopts the mode of intraosseous fixation to strengthen anchorage, and this kind of method also has some deficiencies: such as ulceration of the mucosa caused by the protrusion of the anchorage pins, risk of loosening and falling off of the anchorage pins, periodontal problems caused by local devices, etc. Moreover, the implantation of the anchorage nail requires certain indications, such as too close distance between the adjacent tooth roots, insufficient alveolar bone mass, and failure of correct implantation of the anchorage nail when the opening of the patient is small. In addition to the above methods, sub-apical osteotomies and surgical extraction may be used to correct the bite curve when molar eruption is excessive or other methods are ineffective, but both of these methods are more traumatic than others.

Disclosure of Invention

The utility model discloses lie in remedying some not enough that the method of overextension molars exists among the prior art, provide an adjustment jaw pad that is used for overlength molars that pleasing to the eye, simple, strong adaptability, damage are little.

The adjustable jaw pad for overlength molar includes fixing part and depressing part connected fixedly, the fixing part is made of transparent high molecular material polyethylene die sheet, the fixing part is used to fix the jaw pad onto natural tooth, the depressing part is made of self-setting resin to form the shape of missing tooth, and the depressing part is used to contact with overlength molar to form occlusion pressure to depress overlength molar.

The utility model adopts the transparent film pressing sheet made of high polymer material to form the retention part to fix the jaw pad on the natural tooth crown, which is not limited by the shape of the tooth and has strong adaptability; because the retention component is transparent, the aesthetic appearance is not influenced; the jaw pad is fixed through natural teeth, an additional fixing device is not needed, and the damage is small; the jaw pad restores the occluding function between antagonistic teeth and the extended teeth through the depressing part, so that a patient can depress the extended molar teeth through the biting force or chewing pressure of the patient without an additional force applying device.

Preferably, the retention means is a tooth and mucosa formation obtained by an impression in the patient's mouth, the shape of which corresponds to the shape of the crown and mucosa. The retention component is retained by natural teeth, so that the retention component can be freely taken off and worn and has high flexibility.

Preferably, the depressing member is provided with an occlusal contact point for contacting the excessive molar, and the occlusal pressure is formed by the masticatory muscle of itself to depress the excessive molar.

Because the pressing part is the resin restoration, the resin can conveniently adjust the occlusion contact point to apply correction force in different directions while meeting the intensity required by occlusion and the intensity required by combination of the retention part, and adjust the moving direction of teeth, finally obtain a relatively normal occlusion curve and enough vertical space for repairing an implant, a fixed denture or a movable denture. If the tongue tip is obviously stretched, the tongue tip can be contacted, other points are not contacted, and the stretched tongue tip is depressed; if the elongation of the buccal apex is obvious, the buccal apex can be contacted, other points are not contacted, the elongated buccal apex, such as the buccal apex and the tongue apex, can be obviously elongated at the same time, and can be contacted at the same time and simultaneously reduced.

The utility model relates to a detachable movable jaw pad, compared with other pressing methods, the detachable movable jaw pad has the advantages of small wound, low cost, strong flexibility, high aesthetic degree, good comfort level and the like. The jaw pad of the utility model is taken as a detachable jaw pad, the manufacturing cost is obviously lower than that of the fixed corrector, and the retention part is made of transparent polymer, thereby having elegant appearance. More importantly, the jaw pad is simple to manufacture and convenient to operate, most stomatologists can operate the jaw pad by themselves, the complex referral process is reduced, the clinical time is effectively shortened, the treatment effect is improved, and the satisfaction degree of patients is finally improved.
