Conditions

Pulpal and periapical disease

Interventions

Anatomical marker registration:Dynamic navigation feature points were selected and matched with the anatomic landmarks of patients' dentition

Super thin film positioner registration:Dynamic navigation feature points were selected and matched with the super thin film positioner registration

registration locator made by CAD/CAM:Dynamic navigation feature points were selected and matched with the registration locator made by CAD/CAM

marker-free registration:The dynamic navigation registration is completed by marker-free registration

Inclusion criteria

Inclusion criteria: 1. The tooth was failed to root canal therapy and diagnosed as refractory chronic periapical periodontitis, accompanied by serious destruction of periapical bone tissues and delayed healing of fistula, 2. The root canals were obviously overfilled and accompanied with obvious discomfort; 3. Root canal calcification with periapical shadow could not be cured by routine root canal therapy or failed to the treatment, 4. Root canal therapy complications such as lateral perforation and instrument separation could not be cured by routine root canal therapy; 5. CBCT should be performed preoperatively and postoperatively with a follow-up of at least 1 year.

Exclusion criteria

Exclusion criteria: 1.The affected teeth had severe periodontal disease or root fracture, 2. The affected teeth were residual roots with no value of retention, 3. The patients had systemic diseases such as diabetes mellitus that affected bone healing, 4.The patients were in the acute inflammatory stage, such as acute periapical periodontitis and acute osteomyelitis, 5. The patients with dentition defect on the same jaw as the affected teeth, 6. The patients who lost follow-up and incomplete case data were excluded.
