Technical Field

[0001] The utility model relates to the technical field of artificial teeth, in particular to an adjustable customized artificial tooth. Background Art

[0002] Customized dentures are commonly known as "removable partial dentures", which are restorations that are supported by the mucosa and alveolar bone covered by the remaining natural teeth and base (dental tray) in the mouth and can be removed and worn by the patient. Customized dentures are retained and stabilized by the retention bodies and base components of the dentures, and are used to repair missing teeth and adjacent soft and hard tissues. It is a common method of repairing missing teeth.

[0003] When installing removable dentures, traditional technology often uses adhesives to connect the dentures to the base, which makes the dentures and the base inseparable. When the user eats and chews, food residues are easily stuck in the gap between the dentures and the base. The dentures and the base are inseparable and difficult to clean, making it difficult to clean the food residues, affecting the user's oral hygiene. Utility Model Content
