Brief summary

Implant supported superstructure is necessary for long term success and durability of the implant itself in terms of stresses distribution and fracture strength capability. Stresses falling on an implant are too much greater than those applied on a tooth structure with a periodontal ligament offering a degree of elasticity. The important mechanical and physical properties of materials used for the fabrication of dental prostheses include adequate flexural and tensile strength and modulus of elasticity, maximum fracture resistance, optimal bond strength and adequate polishability.

Detailed description

One objective of implant dentistry is to provide excellent esthetics and soft-tissue profiles in the esthetic zone. Esthetic requirements have focused primarily on the position, inclination, shape, and color of the restoration. However, the peri-implant soft tissue also plays a major role in the esthetics of an implant-supported restoration especially in the anterior region.
