Porous coatings are widely used in dental implants. There has always been production of uncoated dental implants with different designs and materials. Basically, these components are inlaid into the mandible or maxilla bone without using polymethyl methacrylate. Generally, implants are used to support various dental prostheses in the oral cavity. As shown in Figure 10-15, it depicts an uncoated dental implant. The outcomes of dental implants vary greatly. Recently, some researchers have tried to bond dental components to bone by sintering porous powder and fiber coatings on a metal substrate.

Like those used in orthopedics, titanium and cobalt-chromium-molybdenum alloys are also widely used materials. Figure 10-16 shows typical dental implants. The structure of these coatings is the same as that of the orthopedic implants introduced earlier. Early clinical trials of implants with titanium fiber coatings indicate a success rate of over 90%. Therefore, implants with porous coatings have a promising future.

For high-temperature consolidation processes such as hot isostatic pressing, conventional dental components are slightly smaller. However, in the manufacturing of small stainless steel orthodontic brackets via injection molding, the metal injection molding process is well-suited for producing such parts.
