Abstract: Disclosed is a method for digitally designing a dental restoration, wherein a 3D representation of at least a part of the upper or lower jaw is obtained. The 3D representation represents at least a target site for placing the final restoration and at least one antagonist tooth opposing the target site. Furthermore a digital anatomy design of the restoration is provided. The digital anatomy is based at least on a dynamic occlusion and a relative offset of the planned restoration position. Accordingly, a restoration may be designed that does not interrupt the natural occlusion.

Abstract: Disclosed is a method, an occlusion setup fixture and system for recording digital 3D representations of physical teeth models of a patient's jaws and for arranging the digital 3D representations according in a common coordinate system such that the digital 3D representations are arranged according to the patient's occlusion. The recorded digital 3D representations are virtually brought into occlusion by a virtual movement, where the virtual movement includes a translation along a path according to the confined relative movement of the occlusion setup fixture.

Abstract: Presented is an optical coherence tomography system and method to increase imaging depth of optical coherence tomography (OCT) by selective amplification. In a swept-source OCT system with periodically linear wavenumber-vs-time characteristic, the signal in principle is summation of various sinusoidal signals with different frequencies. Each frequency component of the recorded signal carries reflectivity information for a certain depth of the analyzed object. At greater depth inside the analyzed object, the reflectivity information is generally weak due absorption and scattering. An analog or digital electronic circuit selectively filters and amplifies frequencies above some threshold, possibly up to another threshold. In this way, even small signals for relatively larger depths become detectable.

Abstract translation: 提出的是通过选择性扩增来增加光学相干断层扫描（OCT）的成像深度的光学相干断层摄影系统和方法。 在具有周期性线性波数对时间特性的扫频源OCT系统中，该信号原则上是具有不同频率的各种正弦信号的总和。 记录信号的每个频率分量携带被分析对象的一定深度的反射率信息。 在分析对象内部的较深的深度处，由于吸收和散射，反射率信息通常较弱。 模拟或数字电子电路选择性地滤波和放大高于某个阈值的频率，可能高达另一阈值。 以这种方式，甚至可以检测到相对较大深度的小信号。
