Description

A base station for dental implant restoration interlock record

Technical Field

The utility model relates to the field of tooth implantation and restoration, in particular to an abutment for an occlusion record of oral implantation restoration.

Background

Implant restoration has become the best treatment for most tooth loss. The implant can form firm osseointegration after being implanted, has high long-term success rate, can better recover the oral function of a patient compared with the traditional false tooth repair, and better protects the stability and health of soft and hard tissues of the oral cavity. The planting restoration belongs to fixed restoration, and has high precision requirement. In many clinical situations, occlusion recording is a prerequisite to improve the precision of occlusion and to restore proper occlusion. The occlusion recording method of the traditional denture mainly comprises the following steps: a. the two sides of the tooth lacking area of the traditional fixed bridge restoration are provided with the abutment teeth, and the two side abutment teeth are used for supporting the occlusion recording material, so that stable and accurate occlusion recording can be made; b. the partial denture can be removed to repair the missing of free ends of a plurality of teeth, the temporary base and the wax dike are used for making occlusion records, soft mucous membranes are arranged below the temporary base, the accuracy of the occlusion records is not high, but the partial denture can be removed and the occlusion can be adjusted by a small amount. In the implant restoration, particularly when multiple teeth are continuously lost and far free ends are lost, the tooth-lacking area is a mucous membrane or a healing base station, the method for manufacturing a temporary base support and a wax levee on the mucous membrane is poor in elastic deformation accuracy, so that many doctors adopt a method for directly placing an occlusion recording material on the healing base station or manufacturing a temporary base support bearing occlusion material, the healing base station is smooth in surface and small in area, the shape between the mucous membrane of an intra-oral implant and a model artificial gum is often different, and the temporary base support cannot be accurately positioned in the mouth, so that the commonly-used occlusion recording is poor in stability, and the situation of poor occlusion during trial wearing of the implant restoration in clinic is caused. Therefore, a need exists for a new type of abutment for dental implant restoration bite registration.

For example, publication No. CN208625879U discloses an abutment for dental implant restoration bite registration. The base station includes: a support portion for carrying an occluding recording material, the size of a cross section of the support portion increasing from top to bottom; the gum penetrating part is arranged below the supporting part and connected with the supporting part, and the gum penetrating part is of a cylinder structure; and the connecting part is used for fixing the abutment in the implant, and the connecting part is arranged below the gum penetrating part and is connected with the gum penetrating part. The utility model discloses a beneficial technological effect does: the abutment can obtain high-quality occlusion records in tooth implantation restoration, so that a reliable foundation is established for a patient to manufacture a high-precision implantation restoration. However, the utility model still has the following technical disadvantages: because occlusion record base station formula structure as an organic whole, be not convenient for change the supporting part alone when its supporting part does not match with patient's dental crown, and then lead to the doctor to change different base stations conveniently and do the occlusion record many times so that reach accurate data to the patient, bring a lot of troubles for the treatment. Therefore, improvement is necessary to overcome the shortcomings of the prior art.

CN 108784862A discloses a base station for dental implant restoration interlock record, comprising a base station, first recess has been seted up to the bottom of base station, slidable mounting has the round pin axle in the first recess, the bottom welding of round pin axle has the gum bracing piece of wearing, the second recess has all been seted up to the both sides of round pin axle, the third recess has all been seted up on the both sides inner wall of first recess, slidable mounting has first slide bar in the third recess, the one end that two first slide bars are close to each other extends to in the second recess that corresponds respectively, and the inner wall sliding connection of first slide bar and the second recess that corresponds, slidable mounting has first spring in the third recess, the one end welding of first spring is on the one side inner wall that first recess was kept away from to corresponding third recess. The base station is simple in structure and convenient to operate, the base stations can be rapidly disassembled through simple pulling action, different base stations can be conveniently replaced to carry out occlusion recording, and therefore the accuracy of data is improved, and great convenience is brought to people. However, the base station dismounting work of the utility model can be completed only by matching two hands based on a plurality of degrees of freedom, and the service life of the device can be greatly influenced by the pulling action, so that the base station dismounting work of the utility model can be improved based on the working principle of the push pen aiming at the defect of the prior art, thereby realizing simple operation and prolonging the service life at the same time.
