Inclusion criteria
Inclusion criteria: 1.Aged 18–65 years, any gender; 2.Confirmed diagnosis of Stage III or Stage IV periodontitis; 3.At least one mandibular anterior incisor presenting Miller tooth mobility grade II–III. Clinical and radiographic examinations confirm the tooth mobility is solely caused by severe periodontitis, excluding mobility resulting from endodontic lesions, dental trauma or other etiologies; 4.The affected tooth is clinically and radiographically evaluable as restorable: alveolar bone loss <= two-thirds of the root length, with no root fracture; 5.No missing teeth in the mandibular anterior region (i.e., complete mandibular anterior dentition); 6.The mobile tooth has no periapical lesions or pulpitis, or has undergone standardized root canal treatment; 7.Standard initial periodontal therapy (supragingival scaling, subgingival scaling and root planing) completed at our hospital, with well-controlled periodontal inflammation after treatment; 8.Voluntarily signs the informed consent form and is willing to comply with follow-up examinations and treatment procedures.
Exclusion criteria
Exclusion criteria: 1.Systemic diseases: diabetes mellitus (glycated hemoglobin >7%), osteoporosis, immunodeficiency disorders, long-term administration of corticosteroids or bisphosphonates; 2.Pregnant or lactating women; 3.Severe temporomandibular disorders or malocclusion that preclude routine occlusal adjustment; 4.Received occlusal adjustment or periodontal splinting within the past 6 months; 5.Uncontrolled periodontal inflammation after initial periodontal therapy; 6.Heavy smokers consuming more than 10 cigarettes per day who are unable to quit smoking; 7.Tooth mobility attributed to non-periodontal causes including chronic periapical periodontitis, dental trauma, root fracture, etc.; 8.Affected teeth deemed non-retainable based on clinical and radiographic assessment.
