Implantables, commonly known as prosthetics, are medical devices which are used to replace missing or abnormal body parts or organs. Various biomaterials are used for the development of implants such as metals, polymers, ceramics, and composites. The choice of material for implant development depends on application area, duration of implantation, biochemical properties of the material, and the material’s impact on tissues in the vicinity. Polymers have been used in the development of implants as these offer biocompatibility, tissue regeneration, flexibility, and strength. Polymers are widely used in orthopedic, esthetic, and cardiovascular implants beside which they are also been considered in implantable drug delivery devices for target specific drug delivery for the treatment of cancer and other disease indications.
Polymers are used in the development of orthopedic implants such as spine implants, spinal spacers and discs, joint replacement implants, tendons, and ligaments. Increasing geriatric population is estimated to drive the demand for polymer-based orthopedic implants. It is estimated that more than 50% of orthopedic implants are used in patients aged 65 years and above. Moreover, with increasing demand for esthetics, the consumption of esthetic implants such as silicone-based breast implants and maxillofacial implants is projected to grow. Polymers are also used in cardiovascular implants such as drug eluting stents and artificial heart valves. According to an independent study conducted in the U.S., about 75% of coronary stents deployed in the U.S. was polymer-based drug eluting stents. Increase in the prevalence of cardiovascular diseases is expected to drive the growth of the polymer implantables market during the forecast period. However, there have been few adverse events in the recent years regarding the esthetic implants made with silicone, which has hampered the market growth. Additionally, inappropriate selection of materials, low-quality raw materials, and high cost of implants are the concerned areas of the polymer implantables market, which are estimated to restrain the market growth during the forecast period.
