PerioTAG: A Reconstructive Surgical Technique for the Management of Non-Contained Vertical Periodontal Defects
Background:
Periodontal regenerative approaches have demonstrated predictable outcomes mainly in contained intrabony defects, where residual bony walls provide space maintenance and wound stability. Non-contained vertical periodontal defects lack these anatomical prerequisites and are therefore generally considered unsuitable for regenerative treatment, often leaving resective approaches or tooth extraction as the only therapeutic options.
Objective:
The objective of this proof-of-concept report was to describe a novel reconstructive surgical technique =(PerioTAG (tuberosity autogenous graft for periodontal reconstruction) designed to recreate a stable three-dimensional compartment to support periodontal reconstruction and defect stabilization, and to illustrate its clinical feasibility through representative cases.
Materials And Methods:
Three patients presenting with non-contained vertical periodontal defects in the anterior maxilla were treated using the PerioTAG technique. This approach involves reconstruction of the defect with an autogenous corticocancellous block graft harvested from the maxillary tuberosity and rigidly fixed to re-establish a three-dimensional bony compartment. Clinical and radiographic outcomes were evaluated over follow-up periods of up to three years.
Results:
In all cases, the PerioTAG technique allowed stabilization of non-contained vertical periodontal defects, contributing to the preservation of the affected teeth and maintenance of periodontal support. Healing was uneventful, and clinical and radiographic follow-up demonstrated stable periodontal conditions with minimal impact on the esthetic appearance.
Conclusions:
Within the limitations of this proof-of-concept report, the PerioTAG technique may represent a reconstructive option for the management of non-contained vertical periodontal defects not amenable to conventional regenerative or resective approaches. Further controlled studies are required to assess its predictability and long-term stability.
