Background:
The periosteum consists of an outer fibrous layer and an inner cellular layer, where bone cells reside. Hence, it has been suggested that applying periosteum to a periodontal defect may help new bone formation. The purpose of this case study is to present the clinical and radiographic outcomes of a vestibular regenerative approach and the application of a connective tissue graft (CTG) with periosteum to improve the periodontal prognosis of a pathologically migrated hopeless tooth with an endo-periodontal lesion (EPL).
Methods:
A 35-year-old female presented with a hopeless tooth with EPL on #9. To preserve the papilla, a horizontal incision with two vertical releasing incisions was made on the buccal vestibule where the buccal bone was present. A CTG with periosteum was harvested from the tuberosity area. After applying enamel matrix derivative (EMD) and freeze-dried bone allograft (FDBA), the CTG was placed over the defect and stabilized with absorbable sutures. The flap was replaced and sutured, achieving primary closure and healing by primary intention.
Results:
Following regenerative procedure, a localized orthodontic treatment was applied. A minimal ridge resorption, shallow probing depth, and radiographic stability of periodontal bone level were observed.
Conclusion:
This case study shows the successful application of a multidisciplinary approach to save a hopeless tooth with severe bone destruction and a non-contained periodontal defect.
Key Points:
Multi-disciplinary approach including endodontic, orthodontic, and periodontal regenerative procedure can improve the prognosis of natural teeth. It would be beneficial to maintain the blood supply to the crestal part of the flap with apical incision. Connective tissue graft with periosteum could enhance the healing potential when used in adjunct with periodontal regeneration.
Plain Language Summary:
The apical horizontal incision combined with periosteum graft could successfully save a tooth with severe bone destruction and a non-contained periodontal defect. The importance of wound stability on the papillae area was achieved with the vestibular approach with application of the room concept. This method would be beneficial to improve the periodontal prognosis of a severely periodontally compromised tooth.
