Abstract
Researchers are making huge efforts in the field of rebuilding the large missing parts of the human lower jaw, and this represents a major challenge in the field of bone engineering based on reconstruction on the basis of human bone implants. This challenge is to create customized designs that fit the physiological, genetic, and anatomical characteristics of each individual patient. Designing these implants specifically for each case will definitely improve and reduce the recovery period. In order to achieve an improvement in the lower jaw surgery process and clinical practice, the required design of a precise three-dimensional engineering scaffold whose external shape resembles the shape of the missing part of a lower jawbone will reduce the appearance of complications during recovery in addition to preserving the teeth to be implanted and meet mechanical as well as aesthetic requirements. The scaffolds that are designed and will be implanted to replace the missing parts of a lower jaw will be subject to great mechanical loads, for this reason, a scaffold that meets the anatomical conditions is designed on the basis of the 3D geometry of patterns be addressed in research. The process of changing the 3D patterns leads to the modification of the mechanical properties of the scaffold. Because of its complex structure, will be applying additive manufacturing techniques to manufacture this scaffold.
