The application of dental zirconia block in periodontal disease patients
Periodontal disease is one of the main causes of tooth loosening and loss, and the repair treatment should take into account the biological properties, mechanical properties and aesthetic effects. Dental zirconia blocks have significant advantages in periodontal disease repair due to their excellent material properties, and specific applications are as follows:
biocompatibility
Zirconia is bioinert, does not cause tissue inflammation or allergic reactions, and is suitable for long-term implantation into the human body. Its chemical stability can avoid oral corrosion, reduce plaque attachment, and reduce the risk of periodontal disease recurrence.
Mechanical property
The flexural strength is 900-1200 MPa and the fracture toughness (KIC) is 5-10 MPa·m¹/², which can withstand high bite force and reduce the risk of fracture of the prosthesis, especially for patients with weak periodontal supporting tissue.
Aesthetic effect
The light transmission is close to the natural tooth enamel, and the natural appearance of the tooth can be simulated by dyeing and glazing technology, which can meet the aesthetic restoration needs of the anterior tooth area and improve the patient's self-confidence.
Upper implant repair
Immediate implant repair: After tooth extraction due to periodontal disease, the use of zirconia porcelain crown or bridge to achieve immediate repair, shorten the treatment cycle.
Thin gingival biologic repair: Through personalized design of zirconia through gingival structure, maintain the stability of soft and hard tissue around the implant and reduce gingival receding.
Long-term stability: Studies have shown that zirconia restorations have a 100% implant retention rate at 3 years of follow-up and long-lasting aesthetic effects.
Dental defect repair
Inlay and high inlay: It is suitable for cases with large tooth defects or occlusal reconstruction, providing better mechanical support and aesthetic effect.
Veneer repair: For the uneven color or surface defect of teeth caused by periodontal disease, zirconia veneer can improve the appearance of teeth and enhance wear resistance.
Orthodontic assisted restoration
Zirconia bracket: the transparency and comfort is better than the traditional metal bracket, suitable for periodontal disease patients with high aesthetic requirements, reduce mucosal irritation.
Digital technology application
CAD/CAM grinding technology: Through digital design to achieve accurate production of restorations, reduce human error, improve the adhesion of restorations and abutments.
3D printing technology: It is suitable for the repair system of complex curved structures, such as personalized implant abutments, prostheses, etc., to meet the personalized needs of patients with periodontal disease.
Long-term efficacy assurance
The zirconia prosthesis can effectively disperse the biting force, reduce the burden of periodontal tissue and promote periodontal health.
Its wear and corrosion resistance can reduce the frequency of prosthetics replacement and reduce the financial burden on patients.
Severe periodontitis repair case
A 35-year-old female patient with periodontal disease caused multiple loosening of mandibular anterior teeth and loss of posterior teeth was repaired by digital full-mouth implantation and zirconia stent. Reexamination one year after surgery showed that the implant retention rate was 100%, the gingival morphology was stable, and the aesthetic effect was natural.
Thin gingival bioremediation case
A 25-year-old male patient with missing tooth No. 11 received a single anterior dental implant. After 3 years of operation, the gingival morphology was similar to that of natural teeth, and there was no significant difference in bone absorption around the implant.
Periodontal basic treatment
Before repair, periodontal basic treatment (such as subgingival scaling and root surface leveling) should be completed to control inflammation and ensure repair effect.
Restoration design
Adequate occlusal space should be reserved to avoid fracture of the prosthesis caused by overadjustment .
Patient maintenance
Guide patients to use dental floss, interstitial brush and other tools correctly, regular review, maintain periodontal health.
Dental zirconia block is an ideal material for periodontal repair due to its biocompatibility, mechanical properties and aesthetic advantages. Precision repair through digital technology can significantly improve treatment outcomes and patient satisfaction. In clinical application, the indications should be strictly controlled and combined with periodontal basic treatment to ensure long-term curative effect.
