PerioTAG: A Reconstructive Surgical Technique for the Management of Non-Contained Vertical Periodontal Defects

Area of Science:

• Periodontology
• Oral and Maxillofacial Surgery
• Regenerative Dentistry

Background:

• Periodontal regeneration is predictable in contained defects due to bony walls.
• Non-contained vertical defects lack prerequisites for regeneration, often leading to extraction or resective surgery.

Purpose of the Study:

• Introduce the PerioTAG technique for non-contained vertical periodontal defects.
• Demonstrate the feasibility of recreating a stable 3D compartment for periodontal reconstruction.

Main Methods:

• The PerioTAG technique uses maxillary tuberosity autogenous corticocancellous block grafts.
• Grafts were rigidly fixed to reconstruct the 3D bony compartment in three patients.
• Clinical and radiographic outcomes were assessed up to three years.

Main Results:

• PerioTAG successfully stabilized non-contained vertical defects in all cases.
• Affected teeth were preserved, maintaining periodontal support with uneventful healing.
• Stable periodontal conditions and minimal esthetic impact were observed.

Conclusions:

• PerioTAG may offer a reconstructive option for challenging periodontal defects.
• This technique is suitable for cases not amenable to conventional regenerative or resective approaches.
• Further studies are needed to confirm predictability and long-term stability.
