Movable retainer for teeth
Technical Field
The utility model relates to an orthodontic technical field, concretely relates to tooth activity keeps ware.
Background
After the upper and lower jaw teeth are deformed and corrected, the teeth are unstable at new positions, and the dental arch dentition, especially the dentition in the growth period, can cause the deformed and recurrent teeth again under the condition of lacking external force correction due to improper use. In order to consolidate the curative effect and ensure the stable position of the dentition, so that the teeth are always in an ideal and beautiful state, a protective measure needs to be taken on the corrected dental arch, the protective measure is called tooth maintenance, and the method is that a tooth retainer is worn on the corrected dental arch to keep the teeth stable on the new position of the alveolar bone until the reconstruction of the alveolar bone is completed. As an important means for maintaining the position of the teeth after straightening, the tooth holder can be divided into a movable tooth holder and a fixed holder, and the technical schemes of the two holders are superior and inferior, but with the continuous progress of new material processes, the movable holder is more and more widely adopted due to the advantages of convenient replacement, little influence on daily life, overall beauty and the like. The existing movable retainer is generally manufactured by adopting medical resin materials for hot-press molding according to the appearance of the dental arch to manufacture the tooth socket which is attached to the appearance of the dental arch, and transparent tooth sockets are respectively manufactured according to the appearance of the dental arch of the upper jaw and the lower jaw, so that the requirements of shaping and beautiful appearance are met to the maximum extent. However, when the tooth socket is tightly attached to the shape of the arch tooth, the arch tooth is inverted concave, the phenomenon that the tooth socket is inconvenient to take and wear and the sharp part of the tooth prematurely damages the tooth socket often occurs, and because the upper and lower teeth can still be forcefully occluded in the holding process of the tooth, the tooth socket is easily deformed and damaged by pressure, and the stability of a new position after the tooth correction is finished is also unfavorable. This mouthpiece-like movable holder is ineffective if further adjustment is required in the event of an individual tooth misalignment.
Chinese utility model patent CN210354949U discloses a pressure mode movable appliance, including a retainer, a positioning tongue side buckle and an elastic device connecting the retainer and the tongue side buckle, the retainer is provided with a positioning tongue side buckle preformed hole matched with the positioning tongue side buckle position and an adjusting tongue side buckle, two ends of the elastic device are respectively nested and adjusted on the tongue side buckle and the positioning tongue side buckle, the elastic device is an orthodontic rubber or an orthodontic rubber chain, the utility model has the advantages of low cost compared with the traditional process retainer, simple manufacture, less harm and beautiful appearance to the teeth of patients, the appliance closes the gap through pressure mode movable appliance, corrects the gap of a small number of scattered teeth (front teeth) in the back teeth area, which can not only keep beautiful appearance, but also continue to play the effect of correction to unmoved teeth, compared with a full-mouth bonding fixer, the appliance is small and exquisite, and can take off the belt by itself, the patient comfort is high. The utility model discloses an utilize the fixed unscrambler of location function cooperation of keeping the ware to realize that the tooth keeps and corrects dual efficiency, but difficult seeing out, as the ware that keeps that plays basic locate function is in order to realize location function, then must ensure the accurate cooperation of dental arch tooth and the ware that keeps, so can bring equally keep the ware to take the early wearing and tearing and a great deal of inconvenience that the in-process leads to because of the tooth undercut, keep the ware to receive the problem that interlock pressure damaged still to exist simultaneously.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems of the existing tooth holder, the invention aims to provide a new technical solution which has the characteristics of no influence of tooth undercut, convenient taking and durability on the basis of keeping the position of the arch teeth stable, and can effectively avoid the problem of tooth deformity and relapse caused by occlusion contact of the corrected teeth.
Specifically, the utility model provides a tooth activity keeps ware, tooth activity keeps ware includes outer fender of dental arch, the inner fender of dental arch and the steel wire body, the both ends of outer fender of dental arch are connected fixedly with the both ends of inner fender of dental arch respectively through the steel wire body, the arc that the dental arch kept off on the horizontal plane outside corresponds with the dental arch shape of upper jaw and lower jaw tooth near the buccal side, the arc that the dental arch kept off on the horizontal plane inside corresponds with the dental arch shape of upper jaw and lower jaw tooth near the lingual side, the arc of steel wire body on the horizontal plane is parallel with the tooth arc at the both ends of upper jaw and lower jaw tooth, the both ends of steel wire body imbed the both ends of outer fender of dental arch and dental arch inner fender respectively, in use, the dental arch groove that the outer fender of dental arch and the dental arch formed on the horizontal plane keep the dental arch of upper jaw and lower jaw simultaneously in the dental arch groove, the steel wire body that plays supplementary separation effect to preventing upper jaw and lower jaw from interlocking is placed between the mucosa, the contact surfaces of the dental arch outer baffle and the dental arch inner baffle and the dental arch are smooth.
Furthermore, the thickness of the contact surface of the dental arch outer shield and the labial dental arch of the upper jaw and the lower jaw is 1.0-1.5 mm, and the contact surface of the labial dental arch is transparent.
Furthermore, the thickness of the contact surface of the dental arch outer baffle and the dental arch on the buccal side of the upper jaw teeth and the lower jaw teeth is 1.5-3.0 mm.
Furthermore, the dental arch outer baffle and the dental arch inner baffle are both formed by hot pressing of resin diaphragms.
Furthermore, the steel wire body is made of 316L stainless steel wires with the diameter of 1.5 mm. .
The current tooth of contrast keeps the ware, tooth activity keeps the ware to have following beneficial effect:
1. keep off in the dental arch of tooth activity holder outside keeping off and the dental arch, its surface is smooth surface, does not receive the tooth influence of falling the concave, gets to take the convenience, and smooth surface does not fall concave assorted arch with the tooth simultaneously to overcome and kept the problem that the in-process caused the damage because of bellying and tooth frequent collision are being taken to the holder, effectively strengthened keeps the life who keeps the ware.
2. Tooth activity keeps ware can effectively prevent upper and lower jaw dental arch tooth interlock of each other through arranging steel wire physical stamina between the upper and lower jaw mucosa in to jaw tooth especially just rescues the tooth of accomplishing and takes place the not hard up problem in position once more because of the effect of interlock power about reducing.
3. Tooth activity keeps ware keeps the location to going up and down jaw dental arch tooth simultaneously, just so can make the ware of keeping and when stabilizing the dentition position, give play to the supplementary efficiency of correcting of upper dental arch lordosis (colloquially call bucktooth), in addition, keeps off the fine setting of keeping off in with the dental arch through keeping off outward the dental arch, can also realize correcting the still unsatisfactory tooth implementation of back position to indivedual and further correct.
4. The tooth activity keeps ware simple structure is firm, and the preparation is convenient, takes easily, and the cleanness of being convenient for is difficult for arousing the inflammation of tooth decayed tooth or periodontal tissue, and the appearance is pleasing to the eye when keeping effectual, and the foreign body sensation is light.
