Exclusion criteria
Exclusion criteria: 1.Individuals under 18 years of age or over 30 years of age; 2.Presence of tilted or displaced teeth, or missing teeth; 3.Unstable occlusal relationship, unable to consistently achieve the intercuspation position; 4.Test tooth shows obvious tooth structure defects. 5.Test teeth have pulpitis or obvious caries, or have undergone filling treatment, root canal treatment or crown restoration. 6.Test teeth show signs of periodontal disease or significant alveolar bone resorption, or have poor mobility. 7.Have symptoms of poor occlusion. 8.Have bruxism or temporomandibular joint disorder; 9.Currently undergoing orthodontic treatment, or have undergone orthognathic surgery; 10.Have diseases related to the nervous system, mental state, or psychological factors, or there is a lack of ability to understand and follow the instructions given by the researchers.
