It is important to mention that reconstructive osseous surgery has been shown to have little or no success in interproximal furcation lesions of upper molars or in any degree III furcation invasion. Because of technical reasons reconstructive osseous surgery cannot be performed in areas of horizontal bone loss. The patient must have a positive attitude towards the treatment. Regenerative procedures are unpredictable and often times require a second surgery. It is important that the patient understands and accepts the limitations of the procedure.
Regenerative procedures are lengthy.
Several follow up visits are necessary and the patient must comply with a rigorous maintenance program especially during the initial phases of healing. Finally, and most important of all, the patient must have meticulous plaque control. Although plaque control is important for any type of periodontal therapy, it is critical to the success of a regenerative procedure. Another important point in terms of the success of regenerative procedures is the selection of the defect where the procedure will be applied. The following list identifies factors in the selection process that can strengthen procedure outcomes.
