Advances in dentistry mean changes in the biocompatibility of materials, esthetic, the low-affinity with the plate and the properties close to the tooth structure are the basic requirements for modern dental materials.
Boundary Conditions and loadings. 2.5 Properties of materials The mechanical properties of the materials of the dental bridge fixed by implants, and of the mandibular bone of the present study, are summarized in Table 3.
Conclusion The purpose of this modest work is to study the evolution of biocompatibility materials, aesthetics, low, cost-effective and characteristics close to the dental structure are among the essential criteria of modern materials used in odontology.
