Microdisplays are microminiaturized displays having a screen size of less than 25 millimeters (screen size refers to the diagonal distance from one corner to the opposite corner of the screen). They are high-density screens with high resolution and are used in magnified display systems. Microdisplays are often used in conjunction with magnifying optics because of their miniature size. They are used for two basic applications: projection and near-to-eye display. These applications are used in a number of devices across sectors such as consumer electronics, automotive, healthcare, and industrial. Microdisplays can be incorporated in a number of visual electronic products, with new 3G portable communications devices, digital camera wireless applications, portable DVDs, and PCs.

A dental implant procedure helps re-establish missing teeth and comprises three primary components: the implant device, the crown or denture, and the abutment. A dental implant is manufactured using biocompatible metals, titanium, and zirconia, which offer strength, apart from having the ability to fuse with the bone. Some of the major causes of tooth loss are tooth decay, gingivitis, injuries, congenital defects, root canal failure, and excessive wear and tear. Osseointegration is a procedure that helps lock the implant directly into the jawbone. Dental implants are available in different colors and can be customized.
