Furcation Defects

Class II mandibular furcation with the minimal interproximal bone loss.

For many clinicians, the treatment of class II mandibular furcation defects has long involved time-consuming treatment techniques, problematic post-surgical healing, and inconsistent long term results.
Straumann® Emdogain offers a simplified treatment option that shortens the surgical time and recreates lost periodontal tissues. Clinicians have reported improved wound healing and patients have reported minimal pain and swelling after Emdogain treatment.

Treatment of Furcation defects

Anesthetize the area selected for surgery. Avoid injecting a local anesthetic containing adrenaline in the interdental area or in the marginal gingiva adjacent to the periodontal defect which is to be treated.

    *Note: Indication approved in the U.S. is for class II mandibular furcation defects with the minimal interproximal bone loss.

Make intracrevicular incisions. If judged appropriate, make one or two vertical releasing incisions extending out into the alveolar mucosa. Raise full-thickness (mucoperiosteal) flaps on the buccal and palatal/lingual surfaces of the teeth.
Preserve as much of the gingival connective tissue in the flap as possible. Maintain viability of periodontal cells by hydration of the soft tissue with sterile saline.

Reflect soft tissue to expose the periodontal defect.

Remove only the granulation tissue adherent to the alveolar bone and any associated osseous defects necessary to provide full access and visibility to the root surfaces. Remove subgingival plaque and calculus.

Remove "smear layer" by conditioning the root surface with Straumann® PrefGel for two minutes. Rinse thoroughly with sterile saline solution. Avoid contaminating the cleaned and conditioned root surface with blood or saliva after the final rinse.

Apply Straumann® Emdogain immediately on the exposed root surface. Start at the most apical bone level and apply Straumann® Emdogain so that it fully covers the exposed root surface areas.

Complete coverage of the interproximal area and optimal soft tissue adaptation are essential. If deemed appropriate, a periosteal fenestration at the base of the flap may be used to facilitate coronal repositioning of the soft tissue.
Suture materials appropriate for extended stable closure are preferred. The overflow of surplus material during flap closure and suturing should occur.

Intrabony Defects


Straumann® Emdogain is a restorable, implantable material, which consists of hydrophobic enamel matrix proteins with a unique biomimetic effect that promotes predictable re-growth of specific hard and soft tissues within the oral cavity.
Emdogain is intended as an adjunct to periodontal surgery as a topical application onto exposed root surfaces.
Clinical studies on intra-bony defects, including 1-, 2- and 3-wall defects have demonstrated an average of 60-70% defect fill measured as a gain of radiographic bone one year following treatment with Emdogain as well as significant gain in clinical attachment.

Anesthetize the operative area. Avoid injecting a local anesthetic containing adrenaline in the interdental area or in the marginal gingiva adjacent to the periodontal defect which is to be treated.

Make an infraclavicular incision and, if appropriate, one or two relieving incisions. A mucoperiosteal access flap is reflected.

Remove any plaque, calculus and granulation tissue as necessary.

Remove "smear layer" by conditioning the root surface with Straumann® PrefGel for two minutes. Rinse thoroughly with sterile saline solution. Avoid contaminating the cleaned and conditioned root surface with blood or saliva after the final rinse.

Apply Straumann® Emdogain immediately on the exposed root surface. Start at the most apical bone level and apply Emdogain so that it covers the whole root surface.

Primary closure and optimal wound stability when suturing should always be the goal. If it is judged necessary for good primary closure, the flap can be lengthened by cutting through the periosteum in the mucogingival fold. Use sutures of a non-irritating material. Excess Straumann® Emdogain will overflow the edge of the gingiva when suturing the flap.

Regain of functional attachment and new alveolar bone. Do not probe surgically treated areas for 6 months after Straumann®Emdogain treatment.
