Biomaterials are natural or synthetically obtainable materials which are used for prosthetic, diagnostic or therapeutic purposes and which are in contact with tissue, blood and other body fluids within the body [1, 2]. The performances of the materials used in the body are important. The performances of the materials placed inside the body can be examined from different angles. Depending on the area in which the problem is to be solved, a classification can be made at the tissue-organ level or according to the materials used [3]. Biomaterials can be used for a long time or for a short time. The most basic feature that implants should provide is that they are not allergenic or toxic. In addition, biomaterials, designs and mechanical behavior are important qualities. Ceramics are usually blends of metals formed by non-metallic elements. The interatomic bond is ionic or covalent. Ceramic materials have been used as medical materials for many years despite their fragility, porous structure, low tensile strength and low impact strength. With the recent development of new methods, ceramics are used in many different fields of biomolecules. They are widely used in dentistry as gold-porcelain crowns, silica–filled resin composites, and dentures. Due to its high wear resistance, high hardness and excellent corrosion resistance, Al2O3 and yttria–stabilized ZrO2 are widely used in hip prostheses and dental industry with load carrying function [4, 5].
