Abstract
The utility model provides a stress buffer cushion for artificial implanted teeth. An elastic high-molecular-material cushion is added between the tooth crown core of an artificial implanted tooth and a cap-shaped crown to act as a stress buffer cushion. The buffer cushion is a layer of elastic high-molecular-material cushion overspreading the entire tooth crown core, and the thickness of the buffer cushion is 1.0 to 2 mm. The buffer cushion is provided with two holes to be in scarf joint with the holes on the tooth crown core, and thus the buffer cushion is not easy to peel off; the buffer cushion takes the action as a pericementum, and can adjust the allocation of the jaw force on the tooth line; the buffer cushion avoids periodontal traumatism, reduces load for the planted teeth, enhances success ratio of the artificial implanted teeth, and can lengthen service life.
Description
This utility model belongs to medical oral cavity manual tooth planting's equipment class, is canine implant superstructure stress buffer device.
Present medical artificial growth tooth implant divides tooth root (implantation jawbone), neck portion (impenetrating mouth transmucosal) and crown portion (being exposed in the oral cavity).When canine implant is repaired anodontia, be that the tooth root of implantation body is implanted jawbone, the artificial growth root of the tooth is connected with bone interface and is different from natural tooth root, and natural tooth root and bone interface have periodontal membrane, plays a part stress buffer, regulates the distribution of denture upper jaw power.When the artificial growth root of the tooth is connected for bone with the human mouth jawbone, lack elastic device on the overall structure, when being subjected to jaw power, easily cause periodontal trauma.Particularly implantation body and natural teeth are connected together when doing the successive winning of the number on title or bridge and repair with rigid material, by material mechanics principle, the canine implant load that rigidity is big is bigger, and is unfavorable to Dental Implant.At this problem, existing method is: 1. will plant corona and sting the jaw face and slightly reduce, and reduce stressedly, shortcoming is influence masticatory efficiency, and, can extend the reconstruction jaw to the jaw tooth and contact; 2. plant and plant corona resin reparation, shortcoming is that the jaw face abrasion resisting performance of hat is lower; 3. the stake of design macromolecular material is examined in the plantation root of the tooth, and existing unique product is the IMZ implantation body of France, but complex structure, production and processing cost height.
Main purpose of the present utility model is to provide a kind of simple in structure, canine implant stress buffer pad product that cost is lower with stress buffer device for clinical.
The design is to the effect that: adding one deck stress buffer pad (3) between artificial growth corona nuclear (1) and medicated cap shape hat (2), this stress buffer pad is one deck elasticity macromolecular material liner, thick 1.5-2mm, on two holes are arranged, corona nuclear has lip (cheek) for rigid high strength material on it, tongue (jaw) is to through hole (4), this liner and the interlocking of corona nuclear are with slip-off preventing.Liner can have shoulder (5) at hat nuclear base portion.
The design's major advantage is: 1. canine implant does not have periodontal membrane and plays the effect of stress buffer pad, and the design's stress buffer pad plays natural pericemental effect, regulates denture upper jaw power and distributes; 2. avoid periodontal trauma; 3. alleviate the canine implant load; 4. improve the canine implant success rate, and increase its service life.
Accompanying drawing and drawing explanation:
Fig. 1 stress buffer pad
Sequence number among the figure: (1) corona nuclear; (2) medicated cap shape hat; (3) cushion pad;
(4) hole; (5) shoulder;
Embodiment: between corona nuclear (1) and medicated cap shape hat (2), make a macromolecular material liner and be abound with medicated cap shape hat, the thick 1.5mm of liner by the corona nuclear shape.
Claims (1)
1, a kind of stress buffer pad of canine implant superstructure, it is characterized in that: this stress buffer structure is one deck elasticity macromolecular material liner, thick 1.5-2mm, on two holes are arranged, design is between the corona nuclear (1) and medicated cap shape hat (2) of Dental Implant superstructure, and this liner is abound with whole corona nuclear surface.
