The Lythos Digital Impression System (DIS) is an optical impression system intended for use by dental professionals to record the topographical characteristics of teeth, gingiva, and/or palate or stone models. The Lythos DIS is intended for use in conjunction with the production of orthodontic and restorative dental appliances, including orthodontic aligners. The Lythos DIS is a point-of-care turnkey imaging system used in the dental industry; the intra-oral wand hardware and personal computer (PC) based software form an integrated system that produces accurate, high resolution three dimensional (3D) digital images. The end result of an intra-oral patient scan is a 3D digital impression data file that accurately describes the surfaces of teeth, gingiva, and palate within a patient's oral cavity, or the surfaces of a stone model. The system consists of a handheld wand connected to a computer which is housed in a base unit. The computer contains proprietary software to acquire, process, and store the digital 3D image data. Patient information is entered into the software using a touch screen monitor connected to the computer. To capture a 3D image of the patient's dental arch and/or bite, the operator moves the wand along the surface of the teeth to be scanned. A video camera inside the wand captures images of the teeth surfaces. Algorithms in the software process these images into a 3D image and display the 3D image on the computer monitor in real time. The software also saves the 3D image data and identifying patient information to be used by orthodontic or restorative appliance manufacturers to design and manufacture customized appliances. The Lythos DIS device is also equipped with wireless network capability for secure transfer of the 3D image data to the orthodontic or restorative appliance manufacturer. The Lythos DIS is only used to gather the topography of the mouth and teeth, and to upload the data file (.stl) to the data cloud. The data is available to the licensed dental professional to send to a third party manufacturer. The Lythos DIS .stl data file is used in conjunction with CAD/CAM or 3D printing manufacturing processes. The proposed Lythos DIS is not used for the design, diagnosis or treatment planning of orthodontic aligners.

The Digital Impression System for Orthodontic Use is an optical impression system intended for use by dental professionals to record the topographical characteristics of teeth, gingiva, and/or palate. The Digital Impression System is intended for use in conjunction with the production of orthodontic appliances.

The Digital Impression System for Orthodontic Use (DIS) is a handheld intraoral 3D imager intended for use inside the human oral cavity to digitally capture the three-dimensional topography of teeth, gingiva, and/or palate in clinical settings. It is intended to replace traditional cast impressions which are the current standard for recording dental and orthodontic features of patients undergoing orthodontic treatment. The system is intended to be used by orthodontists and orthodontic assistants in an orthodontic office environment. The system consists of a handheld wand connected to a computer which is housed in a base unit. The computer contains proprietary software to acquire, process, and store the digital 3D image data. Patient information is entered into the software using a touch screen monitor connected to the computer. To capture a 3D image of the patient's dental arch and/or bite, the operator moves the wand over the surface of the teeth to be scanned. A video camera inside the wand captures images of the teeth surfaces. Algorithms in the software process these images into a 3D image and display the 3D image on the computer monitor in real time. The software also saves the 3D image data and identifying patient information to be used by orthodontic manufacturers to design and manufacture customized orthodontic appliances.

3M True Definition Scanner is an optical impression system used to record the topographical characteristics of the dentition and/or full arch and preparation areas (including features such as implant scan locator fixtures, braces, brackets, etc.). In addition it can record the topographical characteristics of the oral anatomy (such as soft tissue, gingivae and palate). The three dimensional (3D) model generated from the scan may be further used for the design and manufacturing of dental restorations including implant supported prostheses and partial frameworks, and can be used to design and manufacture physical models of the teeth. It may also be used in conjunction with production of orthodontic appliances, retainers and accessories.

The 3M True Definition Scanner is a digital impression generating system consisting of a computer system on a mobile cart, a lightweight scanning wand, and embedded software (including firmware). Accessory items include a contrast powder to be applied to the patient's teeth and/or oral anatomy and a battery powered powder sprayer. The computer system consists of a commercial off-the-shelf personal computer (PC) and a touch screen monitor. The scanning wand is a hand held optical device that captures high-resolution video images, in real time, as the patient is being scanned. The wand contains an optical system comprised of low intensity LED's, a light sensor, a lens and supporting electronics. The wand is connected to the cart via a high speed data transfer cable. The wand is designed to be easily maneuvered inside the patient's mouth and captures video imagery at 20 frames per second. Those images are converted to 3D data sets and displayed in real time. The software contains high-speed image processing algorithms, real-time modeling, case management, and archival functionality. 3M True Definition Scanner facilitates a digital workflow which reduces or eliminates many steps traditionally required by the dentist and lab, including tray selection, plaster pouring, material dispensing, base & pin, material setting, die cutting, trimming, articulation, packaging and shipping.
