Description

Tooth space retainer

Technical Field

The utility model relates to the technical field of medical equipment, specifically a tooth space keeps ware.

Background

The deciduous teeth are used as chewing organs of children, have the functions of chewing, pronouncing, beautifying, maintaining the length of dental arch and promoting the normal development of the maxillofacial region, and the early loss of the deciduous teeth caused by serious caries, pulp periapical diseases, trauma and the like frequently occurs clinically, so that the inclination of adjacent teeth to lacuna parts can be caused, the normal eruption of inherited permanent teeth can be influenced to cause the arrangement of the permanent teeth to be irregular, the functions of the deciduous teeth can be influenced, the eruption of the permanent teeth is difficult, and the malposition eruption of the permanent teeth causes the occlusion disorder.

Clinically, a device called a space holder is often used to maintain the space between the positions of the missing teeth. The most early loss of deciduous teeth is the loss of a single first deciduous molar or a single second deciduous molar, in which case the gap is generally maintained clinically by using a wire-loop gap retainer fiber. It is composed of a stainless steel band and a bent metal wire. The stainless steel belt rings are two types, one type is preformed, a doctor selects a belt ring with a proper size according to the size of the abutment, and if the preformed belt ring does not have proper specification, the second type is selected, and the technician performs personalized belt ring welding according to the abutment plaster model. After the belt ring is determined, the metal wire is bent according to the length of the edentulous gap, and then the metal wire is welded on the near-middle surface of the belt ring. The retainer needs to be filled with a plaster model after the mold is clinically taken and then sent to a technical factory for manufacturing, the manufacturing period is long, and the missing tooth gap of the child is lost quickly, so that the phenomenon that the missing tooth gap is partially lost when the manufacturing of the gap retainer is sent back to clinical bonding wearing often occurs. In addition, when the second deciduous molar is lost, the first permanent molar often does not fully erupt, the distal crown often has flap coverage, and the band cannot be in place, resulting in failure to make a stand.

Aiming at the problems, the tooth space retainer is simple and convenient to operate, can be manufactured at the side of a chair instantly, does not need to take a model and fill a plaster model and send the model to a technical factory for manufacturing, reduces the possibility of losing the tooth space part caused by the manufacturing period to the maximum extent, completes the doctor seeing as the time is, does not need to make a double-visit, and is greatly convenient for the doctor seeing of a patient. In addition, the improved retainer does not use a belt ring any more, and the arc-shaped metal sheet with the bonding bottom plate is bonded on the near-middle adjacent surface of the abutment to replace the adjacent surface, so that the problem that the space retainer cannot be manufactured due to insufficient eruption of the first constant molar is solved.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a tooth space retainer to solve the current silk ring formula space retainer who provides in the above-mentioned background art, the assembly degree of difficulty is high, and influences erupting of tooth, the problem of gypsum model preparation cycle length.

In order to achieve the above object, the utility model provides a following technical scheme: an interproximal retainer for teeth, comprising: the supporting device comprises an arc-shaped sheet and a supporting semi-ring, wherein hollow tubes are arranged at two ends of one side of the arc-shaped sheet, supporting rods are arranged at two ends of the supporting semi-ring and are matched with the hollow tubes, a silica gel connecting seat is arranged at one side of the supporting semi-ring, a paster is arranged at one side of the silica gel connecting seat, and a spring is arranged inside the hollow tubes.

Furthermore, one side of the arc-shaped sheet is matched with the tooth surface of the tooth to be supported, and one side of the inner part of the arc-shaped sheet is provided with an overflow hole.

Further, the distance between two parallel hollow tubes is 0.6 times of the width of the tooth to be supported.

Furthermore, the distance between the hollow tube and the support rod and the tissue surface of the edentulous gap is 0.5-1mm.

Furthermore, the width of the arc-shaped piece is more than or equal to 80% of the width of the mesial adjacent surface of the tooth to be supported, and a latticed shading is arranged on one side, in contact with the tooth to be supported, of the arc-shaped piece.

Further, the height of the arc-shaped piece is greater than or equal to 30% of the height of the crown of the tooth to be supported.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses an arc piece that sets up, hollow tube and paster, realized when tooth clearance keeps the ware to use, cooperation through hollow tube and bracing piece, can support the width according to tooth clearance adjustment, need not to polish the tooth, thereby the assembly degree of difficulty has been simplified, hollow tube and bracing piece through parallel arrangement, erupt the position to the deciduous molar in the clearance and reserve the space outside, the bracing piece that the symmetry set up makes keeps the ware both sides to exert pressure evenly to both sides tooth, it is effectual to keep, the elasticity of spring makes the support dynamics that keeps the ware keep lasting, through spot facing (operation) arc piece and paster, make arc piece and paster tooth face laminating inseparable, moreover, the chair side site preparation, the preparation is fast, easily wear.
