Dentistry becoming more and more digital along with the whole world. Technologies have changed the dental industry to provide patient care and satisfaction. While the latest advancements ensure you with full comfort, the time you spend in the dental office become more efficient. Dentistry is progressing and below are listed some ways how:
1. Intra-Oral Scanner
The first thing restorative or aesthetic dental work need is an impression of your teeth. Mixing several materials together dentist create a smooth consistency, transfer that to a tray, and put it in your upper or lower jaw. The doctor holds the material up to a few minutes until it solidifies and removes it. Some patients feel uncomfortable during this process because of the material taste and unguided gag reflexes.
Due to these aspects, some important details may be missed which results in the improper fitting of restorations and improper occlusion. Step by step digital dental impression replaces this conventional method making the whole process rather comfortable for the patient.
Intraoral scanners are pen-shaped devices for making direct optical impressions in dentistry which is similar to 3D scanners. This scanner project a light source on the area to be scanned. The imaging sensors capture the dentogingival tissues, and the device software process it creating a 3D surface model. Such 3D models are perfect and more comfortable for patients alternative to traditional plaster models.
2. CAD and CAM
CAD is a short form of computer-aided design. It is computer software that designs a product and documents the design’s process. The CAD may facilitate the manufacturing process by transferring detailed diagrams of a product’s materials, processes, tolerances, and dimensions with specific conventions for the product. It can be used to produce both two- or three-dimensional diagrams. These diagrams can be rotated and viewed from any angle, even from the inside.
Computer-aided manufacturing (CAM) is the use of software and computer-controlled machinery to automate a manufacturing process. CAM software prepares a tooth model for machining by working through several actions. CMA checking if the model has any geometry errors, creating a toolpath for the model, setting any required machine parameters (cutting speed, voltage, cut/pierce height, etc). Once the model is prepared for machining, all of that information gets sent to a machine to physically produce the part.
There is no CAD without CAM. CAD focuses on the design of a product, how it looks, and functions while CAM on how to make it.
3. Dental 3D Printing
The possible applications of 3D printing technology are endless. If you ever needed a dental restoration procedure probably know how it performs. First, your dentist takes an impression of your upper and lower jaw and sends it to the laboratory. Then both of you wait for the lab to create the dental models. After the laboratory has done their work, you will return to the dentist to end the procedure.
This process may last up to several weeks while the use of 3D printing cuts this time to one appointment. A tech-savvy dentist will scan your mouth with an intra-oral scanner, then will digitally design the desired treatment, and send this information to the 3D printer that brings it to life. While this saving you weeks of waiting, it also provides you with more accurate results.
Dental 3D printing has many applications and can be used for Inlays and onlays, dental crowns, implants, mouth guards, dental bridges, dentures, and rthodontic appliances (clear aligners).
While conventional methods make it possible for your dentist to fix any defects only after the procedure done, 3D printing allows the doctor to prevent any misconceptions digitally before the printing.
