Modifications of the subpedicle connective tissue graft technique: a predictable procedure for covering exposed roots.

This article reviews modifications to Nelson's technique for covering exposed roots using an autogenous connective tissue graft covered by a double papilla pedicle graft. Case reports will illustrate how this technique can be used for both root surfaces pathologically exposed to the oral environment and those previously restored with cosmetic bonding procedures. Enhancements of this procedure over Nelson's original description will be enumerated, and advantages over other root coverage modalities will be presented.
