Summary

Intraosseous defects are characterized by vertical bone loss within the borders of the alveolar bone surrounding the teeth due to periodontal disease and are considered a clinically concerning condition. Treatment of intraosseous defects involves regenerative techniques aimed at reconstructing lost periodontal structures (including bone, cementum and periodontal ligament). In the process of periodontal regeneration, it is of great importance that the blood clot attached to the root surface is protected from mechanical and microbiological factors and remains in a stable biological environment. Post-surgical wound dehiscence can lead to impaired clot stabilization and infection, negatively affecting the healing process and thus jeopardizing the results of the treatment. Regenerative therapies using conventional flap surgery have been reported to provide significant improvements in clinical attachment levels, but carry a high risk of loss of attachment if flap management is inadequate. Furthermore, complications such as difficulty in primary closure, risk of membrane exposure and tissue detachment have been observed with conventional flap techniques. Various minimally invasive flap surgery techniques have been developed to prevent these complications. One of the minimally invasive periodontal flap techniques is the full papillary preservation technique. Unlike traditional methods, this innovative approach provides vertical access to the defect area from the buccal and lingual adjacent areas without any incision in the papillary region. This technique reduces the risk of wound healing failure and exposure of regenerative biomaterials due to the fully preserved interdental papilla over the bony defect. The aim of our study is to compare the short-term (6 months) radiographic and clinical results of the Entire Papilla Preservation (EPP) technique with the Conventional Flap Surgery (CFS) technique.

Conditions

• Periodontal Intrabony Defect

Interventions

Type	Name	Description
PROCEDURE	Entire Papilla Preservation Technique	A buccal intrasulcular incision was made in the tooth with the defect and a vertical incision was made extending from the buccal center of the tooth to the mesial papillary crest and crossing the mucogingival line. Then, using a micro periosteal elevator, a full-thickness mucoperiosteal flap was lifted from the incision site to the defect under the papilla. After removal of the granulation tissues in the area, bone graft was applied for regenerative purposes and the vertical incision was sutured with 6/0 polypropylene suture using simple suture technique.
PROCEDURE	Conventional Flap Surgery Technique	After buccal and lingual intrasulcular incisions were made to eliminate the teeth and papillae adjacent to the defect, a full-thickness mucoperiosteal flap was raised in the vestibular and lingual direction with a periosteal elevator. After removal of the granulation tissues in the area, bone graft was applied for regenerative purposes and the papillary incisions were sutured with 5/0 polypropylene suture using simple suture technique.
