What are the advanced developments in dentistry

New ways in dentistry

One of the techniques uses three-dimensional (3D) printing processes to replace missing teeth. Currently, 3D printers are available from € 500, which are no bigger than a briefcase and just as easy to transport. Easy and affordable access to 3D printers gives dentists the opportunity to bring back the smiles on people's faces in some of the world's poorest and most remote regions.

And this is how it works: First, the dentist uses an intraoral scanner, an instrument that looks like a magic wand, to scan the patient's oral cavity. Each elevation and deepening is recorded at 3,000 images per second and put together in a digital file that is sent to a team of specialists at MegaGen. The team uses the data to create a new set of custom-made teeth. They then send the plans formatted for the 3D printer to the dentist. The printer uses a high-powered laser to convert liquid resin into a perfect tooth. This is anchored in the patient's jaw with a tiny metal screw. In implantations of this type, the screw is used to grow into the bone. Precise, strong, sterile, durable - and the process only takes a few minutes.

The technology behind this process was made possible by the pioneering work of MegaGen Implant. In its state-of-the-art manufacturing facility in Daegu, South Korea, MegaGen designs and manufactures some of the most advanced bionic teeth in the world, as well as the tiny screws that attach the new teeth to the jaw. The teeth are carefully machined from medical titanium, a material that is incredibly resilient and can be adapted as an implant down to the smallest detail. To ensure that new teeth grow quickly and completely into the bone, MegaGen has developed a novel process. Each screw is sandblasted, leaving tiny structures on its surface that help create the connection and an exceptionally strong hold to the bone. In addition, every tooth is coated with calcium ions, which support bone growth and prevent the body from rejection. The improvements in procedural processes by MegaGen have reduced treatment time from six months to a single day. Patients can have the implant inserted in the morning and chew an apple at bedtime.

While such bionic implants can be produced ever faster and easier, their costs are falling - which makes implants more and more affordable in developing countries as well. In countries with advanced medical technology, high-tech methods can also be used in oral health. A highly developed scanning device called CBCT allows dentists to look deep into the teeth and bones and delivers an extremely accurate 3D image. In conjunction with the interoral scanner, this device creates a perfect virtual image of the oral cavity for the dentist. This allows you to drill the guide holes of the implants with microscopic precision. At the same time, MegaGen produces even more durable teeth. They are cut out of an extremely tough composite using computers and state-of-the-art grinding machines. It only takes about four hours to produce and implant 12 new bionic teeth.
