Furcation Invasions Deep degree II furcation invasions on the buccal of upper and lower molars and linguals of lower molars cannot be treated with a resective procedure since they do not become maintainable. The option available is to try to rebuild the attachment apparatus in the furcation area. 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.
