Description

Safe tail-end molar positive locking correction device

Technical Field

The utility model belongs to the technical field of oral medical instrument, concretely relates to device is rescued in positive locking of safe terminal molar.

Background

Closure, also known as a straddle deformity, is a malocclusion of posterior teeth. According to the buccal-lingual position relationship of the upper and lower posterior teeth, the closure can be clinically divided into positive closure and negative closure. The positive closure means that the lingual surface of the lingual cusp of the maxillary posterior teeth is positioned on the buccal side of the buccal surface of the buccal cusp of the mandibular posterior teeth, and the occlusal surfaces are not in occlusal contact and are common in clinic. The locking can occur on one side of the dental arch and can also occur on two sides of the dental arch; more frequently occurring on one side of the dental arch and less frequently occurring on both sides of the dental arch; permanent occlusions are more common and deciduous occlusions are less common. Most commonly found in the second molars of the upper and lower jaws, locking of the anterior molars area also occurs more frequently. The orthodontia can reduce the chewing function and the facial asymmetry deformity, induce the temporomandibular joint disorder and induce the deep occlusion of the anterior teeth. Clinically, the following two methods are generally used: 1. moving the upper and lower posterior teeth to the buccal side or the palatal side to release the locking relation under the premise of raising the occlusion to achieve normal occlusion, but such a method may cause a traction rubber band to slide into the neck part of the distal molar to cause serious periodontal damage to the teeth; 2. implant micro implants on the locking lateral bed, pull molars, correct positive locking, but this approach creates an implant wound.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention provides a safety end molar positive locking correction device to solve the deficiencies in the prior art.

In order to achieve the above purpose, the purpose of the present invention is achieved by the following technical solutions:

the base and the tooth closing pad are integrally formed, the base wraps the front side of the maxillary palate, the tooth closing pad covers the occlusal surfaces of incisors, cuspids, first premolars, second premolars and first molars on the left side and the right side of the maxillary jaw, the traction hook comprises a rod end and a hook end, the rod end is fixed in the base behind the maxillary side, the hook end extends towards the throat direction, one end of the safety wire is fixed in the tooth closing pad positioned on the first molars, the other end of the safety wire extends towards the throat direction, one end of the adjacent hook spans over and is fixed at the adjacent position between the tooth closing pads, and the other end of the adjacent hook spans over and is fixed in the base on the maxillary side.

The safety tail end molar orthodontics locking and correcting device is characterized in that three groups of adjacent hooks are respectively bridged at the adjacent position between the occlusal pad of the canine and the occlusal pad of the first premolar, the adjacent position between the occlusal pad of the first premolar and the occlusal pad of the second premolar, and the adjacent position between the occlusal pad of the second premolar and the occlusal pad of the first molar.

The safety tail end molar positive locking correction device is characterized in that the traction hook is arranged outside the base and close to the base, and a U-shaped bend is arranged in the same direction as the bending direction of the end of the hook.

Above-mentioned safe terminal molar is just locked and is rescued device, wherein, draw the hook and adopt the stainless steel wire of diameter 0.8mm to make.

Above-mentioned safe terminal molar is just locked and is rescued device, wherein, the safety guarantee silk adopts the stainless steel wire of diameter 0.5mm to make.

The utility model discloses technical scheme's beneficial effect is:

structural design is reasonable, can effectively correct the positive closure of terminal molar, and is also fine to the effect of correcting of the serious positive closure of unilateral posterior teeth, and the wound is not created, can prevent to pull the periodontal injury that the rubber band slided into the terminal molar neck of upper jaw and brought, promotes greatly and corrects the effect, and is safe in utilization.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.

Referring to fig. 1, the utility model discloses safe terminal positive closure of molars is rescued device and is included base 1, the tooth closes pad 2, a set of hook 3 that pulls, a set of safety guarantee silk 4 and at least a set of neighbour hook 5 between, base 1 and tooth close pad 2 integrated into one piece, base 1 wraps the upper jaw palate front side, the tooth closes pad 2 and covers the upper jaw left and right sides incisor, the cuspid, first preceding molars, the occlusal surface of second preceding molars and first molars, it includes pole end 31 and hook portion end 32 to pull hook 3, pole end 31 is fixed in the base 1 that is located upper jaw side rear, hook end 32 extends to the throat direction, the one end of safety guarantee silk 4 is fixed in the tooth that is located first molars closes pad 2 in, the other end extends to the throat direction, 5 one end of neighbour hook is fixed in the base 1 that is located the upper jaw side, the other end strides over and is fixed in the department of adjacency between the tooth closes pad 2.

In the preferred embodiment, there are three sets of adjacent inter-hooks 5 for securing positions in the present device, spanning the abutment between the bite block 2 of the canine and the bite block 2 of the first premolar, the abutment between the bite block 2 of the first premolar and the bite block 2 of the second premolar, and the abutment between the bite block 2 of the second premolar and the bite block 2 of the first molar, respectively.
