Utility model content
Based on this, be necessary to there is for full porcelain artificial tooth the problem that easy porcelain collapses, a kind of glass ceramics artificial tooth is provided.
A kind of glass ceramics artificial tooth, comprise the glass-ceramic substrate of cutting forming, described glass-ceramic substrate surface comprises first surface and second surface, the part contacted with gingiva is first surface, the part do not contacted with gingiva is second surface, and described second surface successively sinter molding has dyeing enamel coating and glaze layer.
Wherein in an embodiment, the apparent height of described first surface is no more than 1/3 of described glass-ceramic substrate apparent height.
Wherein in an embodiment, described dyeing porcelain thickness is 0.2 ~ 0.3mm.
Wherein in an embodiment, described glaze layer comprises the first glaze layer first glaze layer and the second glaze layer.
Wherein in an embodiment, described second glaze layer is carved with developmental groove.
Above-mentioned glass ceramics artificial tooth, owing to being the glass-ceramic substrate of cutting forming as the matrix of main body, good integrity, intensity is high, can reduce stress, and result of use is stablized.And in manufacturing process, enamel coating needs cooling after Overheating Treatment, because the heat conductivity of porcelain is poor, when dyeing enamel coating cooling meat, the larger temperature difference can be there is between glass-ceramic substrate surface and the dyeing enamel coating being attached to glass-ceramic substrate surface outer surface, glass-ceramic substrate surface can limit the contraction of dyeing enamel coating, causes in dyeing enamel coating and produces tensile stress; If dyeing enamel coating is coated on glass-ceramic substrate surface completely, and the thickness of dyeing enamel coating remains unchanged, such meeting is because the apparent height of dyeing enamel coating is excessive, thus the enamel coating that causes dyeing holds tensile stress that can't stand generation and fine fisssure occurs, and life-time service collapses porcelain unavoidably.And when using glass ceramics artificial tooth, the first surface contacted with gingiva is main stressed concentrated place, therefore dyeing enamel coating is sintered in the second surface do not contacted with gingiva, reduces the stressed of dyeing enamel coating, namely reduce the probability of dyeing enamel coating generation fine fisssure, thus reduce the probability collapsing porcelain.
Accompanying drawing explanation
Fig. 1 is the structural representation of glass ceramics artificial tooth.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described further.
As shown in Figure 1, a kind of glass ceramics artificial tooth 100, comprises enamel coating 110.Described enamel coating 110 outwards comprises glass-ceramic substrate 112 and dyeing enamel coating 114 successively.The surface of described glass-ceramic substrate 112 comprises first surface 1122 and second surface 1124, the part contacted with gingiva 200 is first surface 1122, the part do not contacted with gingiva 200 is second surface 1124, and described dyeing enamel coating 114 is sintered in described second surface 1124.The surperficial sinter molding of described dyeing enamel coating 114 has glaze layer 120.
Above-mentioned glass ceramics artificial tooth 100, owing to being the glass-ceramic substrate of cutting forming as the matrix of main body, good integrity, intensity is high, can reduce stress, and result of use is stablized.And in manufacturing process, enamel coating 110 needs cooling after Overheating Treatment, because the heat conductivity of porcelain is poor, when dyeing enamel coating 114 cooling meat, the larger temperature difference can be there is between glass-ceramic substrate 112 and the dyeing enamel coating 114 being attached to glass-ceramic substrate 112 outer surface, glass-ceramic substrate 112 can limit the contraction of dyeing enamel coating 114, causes in dyeing enamel coating 114 and produces tensile stress; If dyeing enamel coating 114 is coated on glass-ceramic substrate 112 surface completely, and the thickness of dyeing enamel coating 114 remains unchanged, such meeting is because the surface area of dyeing enamel coating 114 is excessive, thus the enamel coating 114 that causes dyeing holds tensile stress that can't stand generation and fine fisssure occurs, and life-time service collapses porcelain unavoidably.And when using glass ceramics artificial tooth 100, the first surface 1122 contacted with gingiva 200 is main stressed concentrated place, therefore dyeing enamel coating 114 is sintered in the second surface 1124 do not contacted with gingiva, decrease the stressed of dyeing enamel coating 114, thus reduce the probability that fine fisssure occurs dyeing enamel coating 114, namely reduce the probability collapsing porcelain.
Wherein in an embodiment, the apparent height of described first surface 1122 is no more than 1/3 of described glass-ceramic substrate 112 apparent height.If described first surface 1122 is long, then described glass ceramics artificial tooth 100 can be caused to embed gingiva 200 excessively dark, when laboratory rodent chow, wear and tear too much to gingiva 200, cause the diseases such as gingivitis, cause human body uncomfortable; If described first surface 1122 is too short, then can cause the surface exposure of glass-ceramic substrate 114 outside gingiva 200, cause whole glass ceramics artificial tooth 100 insecure, have and easily cause glass ceramics artificial tooth 100 to loosen the risk causing coming off.So, the height of first surface 1122 is set to less than 1/3 of the apparent height accounting for described glass-ceramic substrate 114, for comparatively reasonably arranging.
Wherein in an embodiment, described dyeing porcelain thickness is 0.2 ~ 0.3mm.The effect of described dyeing enamel coating 114 mainly makes described glass ceramics artificial tooth 100 closer to the tooth of human body itself, makes glass ceramics artificial tooth 100 intensity larger, longer service life simultaneously.And enamel coating 110 blocked up easily causing cracks, therefore it is comparatively reasonable that the thickness of dyeing enamel coating 114 is arranged on 0.2 ~ 0.3mm.
Wherein in an embodiment, described glaze layer 120 comprises the first glaze layer first glaze layer and the second glaze layer.When making first at unsintered dyeing enamel coating 114 external coating first glaze layer, and together sinter with dyeing enamel coating 114, sinter the second glaze layer at the first glaze layer external coating again, glaze layer 120 like this can as required evenly be reasonably distributed in enamel coating 110 surface, surface quality and result of use good.
Wherein in an embodiment, described glaze layer 120 is carved with developmental groove.In a specific embodiment, developmental groove is engraved on the second glaze layer.The acting as of described developmental groove increases bites power broken when chewing, and chews more abundant.So collapse for reduction porcelain, be not necessary.
