Objective: After periodontal specialist examination, periodontal treatment, or on the basis of the upstream after surgery, according to the teeth and adjacent teeth recovery conditions for the double crown abutment splint design, and finally the periodontal splint treatment were analyzed to observe the double crown splint restorative treatment of periodontal disease in clinical results. Methods: 10 cases of clinical cases. Inclusion criteria: (1) moderate to severe periodontitis and no contraindications to surgery 10 patients. (2) loose teeth degree Ⅱ - Ⅲ degree of periodontal tissue destruction evident. (3) x-ray showed alveolar bone resorption of root length 1/2-2/3. (4) patients voluntarily accept double crown splint therapy. Exclusion criteria: (a) severe progressive periodontitis or surgery in patients with contraindications. (2) can not be thoroughly root canal treatment. (3) teeth loose degree Ⅲ degrees, furcation Ⅲ degrees, alveolar bone resorption than 2/3. (4) the patient does not accept the double crown splint therapy. 1, taking X-rays of teeth periodontal understand the situation on the teeth for perfect root canal treatment. 2, the basic treatment: the patient do a detailed oral hygiene instruction, OK supragingival, subgingival scaling (root planing), rinse and local periodontal pockets on drugs. 6-8 weeks before they are fixed. 3, basic treatment, periodontal pocket depth is still greater than 5mm, furcation of Ⅱ or Ⅲ degree, need bone grafting and GTR, will have periodontal surgery. Periodontal surgery cases, the line will have 2-3 months to repair treatment. 4, the abutment periodontal recovery options: You can not loose or loose after periodontal treatment Ⅰ degree integrated within alveolar bone resorption 1/3 of the tooth is designed to retention-type abutments will be consolidated by periodontal treatment Pine Ⅱ degree or alveolar bone resorption of teeth 1/2-2/3 Cone sleeve is designed to cushion the crown. Results: The clinical criteria: From retention, comfort, chewing three aspects were evaluated. In the collection of 10 cases, the patients gave effect after the repair to the affirmative. After a year of these 10 cases cases for referral. There are nine cases considered to be very satisfactory: denture retention is good, inside and outside the crown fit, no gum recession, occlusal no Alice moving, no pain, beautiful and comfortable, masticatory function well. There is one case of gingivitis symptoms appear, after scaling subgingival plaque and smoke spot, and once again for patients with health guidance, the patient recovered well. Conclusion: Based on the 10 cases of periodontal disease for a total of 45 double abutments denture treatment, the results showed that periodontal disease can quickly adapt to the telescopic denture, masticatory function improved significantly. Double crown for the treatment of periodontal disease is periodontal splint has a positive effect, especially for patients with moderate to severe periodontitis, periodontal disease mitigation and restoration have a good clinical efficacy. But note that should guide the patient is clinically double crown splint for regular cleaning maintenance.
