    • The invention relates to a process for producing a titanium and ceramic adhesive composite system, and a titanium and ceramic adhesive system produced therefrom. Said system can be used to improve the adhesion of ceramics, intended for pure titanium or titanium alloys, to a structure consisting of pure titanium or a titanium alloy. Said improvement is attained in that silicon ions (4) are inserted into the surface (1) of a structure consisting of pure titanium or a titanium alloy by ion implantation with ion beams (3) between the atoms (5) of the titanium or the atoms (5) of the titanium alloy. Said silicon ions form a titanium and silicon layer (2) in the surface (1) of the structure in the penetration layer of the ion implantation, on which titanium and silicon layer crystalline, non-metallic inorganic materials are applied, and an adhesive composite is produced with said materials.

    • Means to decrease the effects of polymerization shrinkage, increase stiffness, decrease the coefficient of thermal expansion to a greater extent than previously possible, and improve the durability of composite restorations by use of improved microcrystalline glass inserts. Shaped pieces of assorted sizes within the range of one-half to 10 millimeters are heat treated to produce microcrystallinity in which the crystalline phases, such as for example stuffed beta quartz, beta-eucryptite, beta-spodumene solid solutions, and keatite and/or other phases, give the microcrystalline glass pieces exceptionally low coefficients of thermal expansion and other desirable properties. Compositions and heat treatment conditions are given to provide the insert pieces with the desired translucencies/opacities, colors, and shades, to match a range of those properties found in teeth. Treatment of the inserts with an organofunctional silane with or without an additional resin coating provides for chemical bonding with composite resins. Cavities in teeth are partially filled with unhardened composite material, and microcrystalline glass inserts of appropriate size, shape and appearance are pressed into the cavity so that the insert constitutes as much as possible of the finished restoration. The composite containing the insert is polymerized either by light, chemical, or combined cure mechanisms, and contoured and polished.
    • 降低聚合收缩效果,增加刚度,减少热膨胀系数比以前更大的方法,并通过使用改进的微晶玻璃插入物来提高复合材料修复体的耐久性。 热处理在一半至10毫米范围内的各种尺寸的成形片,以产生微晶,其中结晶相,例如填充的β石英,β-锂钇石,β-锂辉石固溶体和酮钙石和/或 其他相,给予微晶玻璃片特别低的热膨胀系数和其它所需的性能。 给出组合物和热处理条件以提供具有期望的透光性/不透明度,颜色和色调的插入片,以匹配在牙齿中发现的那些性质的范围。 用有机官能硅烷处理带有或不带有附加树脂涂层的插入物提供与复合树脂的化学键合。 齿中的腔部分地填充有未硬化的复合材料,并且具有适当尺寸,形状和外观的微晶玻璃插入件被压入空腔中,使得插入件尽可能地构成完成的修复体。 包含插入物的复合材料通过光,化学或组合固化机理聚合,并进行轮廓和抛光。
