1. What are fixed dentures? Fixed dentures use the natural teeth on one or both sides of the edentulous area as abutments, make various types of retainers on the abutments, and make bridges in the edentulous area, which are connected as a whole through connectors, and finally cemented A prosthesis that is fixed on the abutment and cannot be worn by the patient.

Where does the tooth feel come from?First, let's understand where the feeling of teeth comes from. The structure of the tooth can be divided into three parts from the external shape: the crown, the neck and the root. The crown is the main part of the chewing function, and the shape of different teeth is different. The root of the tooth is buried in the alveolar bone and is the supporting part of the tooth. The neck is the arcuate part where the crown meets the root. The structure of teeth can be divided into enamel, cementum, dentin and pulp according to histology.

Dental digital workflow is using CAD/CAM (computer-aided-design and computer-aided-manufacturing) to design and creation of dental restorations, especially dental prostheses, including crowns, crown lays, veneers, inlays, and Onlays, fixed dental prostheses bridges, dental implant-supported restorations, dentures (removable or fixed), and orthodontic appliances.We will Divide the process into four parts: 1. getting a Digital impression for the start, 2. CAD(Computer-aided design), 3. CAM(computer-aided manufacturing), and 4. post-processing.1.

What is a cracked tooth Cracked teeth, also known as tooth microcracks, also known as incomplete tooth fractures, refer to the non-physiological cracks that occur on the surface of the crown and are not easy to find. Shallow fissures generally have no obvious symptoms, but deep cracks may cause sensitivity to cold and heat stimuli, or bite discomfort.

For decades, the traditional dental impression process involved impression materials and techniques that required multiple steps and appointments. While effective, it relied on analog rather than digital workflows. In recent years, dentistry has gone through a technological revolution with the rise of intraoral scanners.Whereas impression materials and techniques were once the standard protocol, the digital impression process enabled by intraoral scanners offers significant upgrades.

Dental medical software can be divided into two categories: dental patient management software, which holds patients’ personal information and visit information, and dental treatment software, which is used for documenting and working with the patient’s treatment history and its planning. All programs from the second group can be classified as dental CAD/CAM software.
