Abstract
The utility model discloses a space retainer. The space retainer is used for being adhered on abutment teeth at two ends of an edentulous space to remain the size of the edentulous space. The space retainer comprises a fiber belt and resin, the fiber belt is impregnated in adhesive, the resin is coated on the impregnated fiber belt, and the space retainer is attached on lingual dental crowns and/or buccal dental crowns of the abutment teeth through the adhesive. The space retainer dose not contact with the periodontal tissue, has fine biocompatibility, is capable of avoiding metallic allergy, is low in foreign body sensation and easy to clean, is attractive and the like.
Description
Technical field
This utility model relates to a kind of space maintainer, particularly relates to the fixed space maintainer of a kind of fiber reinforced composite resin.
Background technology
In the stomatology field, early lose case for indivedual deciduous molars, tradition adopts wire ring formula keeper to keep the gap.Studies show that about the present conventional wire ring formula keeper that adopts its life-span, generally about 1 year, failure cause mainly was the forfeiture of bonding cement and the breakage (as snapping) of keeper itself.And the comfort level of wire ring formula keeper is relatively poor.
Therefore, the space maintainer that needs a kind of more comfortable and longer service life.
The utility model content
This utility model just is being based on top consideration and is making.Fiber reinforced composite resin (fiber-reinforced composite resin, be called for short FRC) is widely used in the Clinical Science of Stomatology field, as periodontal splint, just abnormal fixed retainer, the wound tooth is fixed and the making of interim pontic etc.This utility model utilizes this fiber reinforced composite resin to make the fixed space maintainer of fiber reinforced composite resin (fiber-reinforced composite resin fixed space maintainer, be called for short FRC-FSM), so that a kind of brand-new alternative gap maintenance technology to be provided.This FRC-FSM be by with the fiber reinforced composite resin bonding on the abutment at edentulous space two ends to keep the fixed space maintainer of edentulous space size.
According to an aspect of the present utility model, a kind of space maintainer is provided, be used to be bonded on the abutment at edentulous space two ends to keep the edentulous space size, it comprises: fabric strip, this fabric strip is handled through the immersion of immersing in binding agent; And resin, be coated on through immersing on the fabric strip of handling, wherein, this space maintainer sticks on the tongue side corona of abutment by binding agent, perhaps sticks on the cheek side corona of abutment, perhaps sticks to simultaneously on the tongue side corona and cheek side corona of abutment.
Selectively, above-mentioned space maintainer also sticks on the near/distal surface of abutment by binding agent.
Selectively, when space maintainer adhered to the tongue side corona of abutment and cheek side corona simultaneously by binding agent, space maintainer separated each other at the edentulous space place.
Selectively, when space maintainer adhered to the tongue side corona of abutment and cheek side corona simultaneously by binding agent, space maintainer was bonded to each other together at the edentulous space place.
Preferably, resin is a stir-in resin, or light-cured resin.
Preferably, fabric strip is made by parylene's glycol ester.
Preferably, binding agent is made by hydroxyethyl methylacrylate.
Than traditional wire ring keeper, FRC-FSM has and does not contact periodontal tissue, advantage such as good biocompatibility can prevent metal allergy, and foreign body sensation is little, and is easy to clean, attractive in appearance.

The specific embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings.
Fig. 1 is the sectional view according to space maintainer 1 of the present utility model.This space maintainer 1 comprises fabric strip 2, bonding agent 3 and resin bed 4, and it is made like this: fabric strip 2 is immersed in the bonding agent, take out then, apply light-cured resin in the above, through the illumination after fixing.Fabric strip 2 can be made by parylene's glycol ester, for example is the BIOSPLINT fabric strip that French Bi Lan company produces.Resin 4 can be made by bisphenol-A methacrylate ethylene oxidic ester (BIS-GMA) or double methyl methacrylate triethylene glycol ester (TEGDMA).Selectively, resin 4 can be commercially available Filtek
TMStir-in resin.Bonding agent 3 can be made by hydroxyethyl methylacrylate (HEMA).Selectively, bonding agent 3 is Adper
TMBonding agent.
Fig. 2 is the vertical view of space maintainer 1 when being applied between abutment A, the B of gap both sides, and Fig. 3 is the view when the tongue side direction is observed, and Fig. 4 is the view of cutting open along the A-A line among Fig. 3.When using, with bonding agent space maintainer 1 is bonded on the tongue side corona and near/distal surface of abutment A and abutment B, realize keeping the purpose of gap thus.
As another embodiment, on the corona that space maintainer 1 sticked to the tongue side and near/distal surface, can also be with space maintainer 1 ' stick on the corona and near/distal surface of cheek side, to obtain stronger support and retentivity.As shown in Figure 5, it should be noted that space maintainer 1 and space maintainer 1 ' can separate each other promptly to have clearance G at the gap place, also can G very close to each other, but at gap place space maintainer 1 and space maintainer 1 ' bond together.
Be noted that in the above embodiments space maintainer 1 sticks near/distal surface of abutment, yet, only stick on the corona and also be fine, that is, need not to stick near/distal surface of abutment.
Space maintainer of the present utility model need not tooth preparation, does not contact periodontal tissue, straightforward manipulation, and program simplification shortens the course of treatment, and it is little to take up room, and foreign body sensation is little, and is easy to clean, attractive in appearance, good biocompatibility, the metal allergic constitution is suitable for.
Though described this utility model in detail with reference to specific embodiment, apparently, under the condition that does not depart from spirit and scope of the present utility model, those skilled in the art can make various changes and modification.
