Correction of Furcation Defect

What does that mean?

A furcation is the area of a tooth where the root divides from the common root trunk. It occurs due to progression of periodontal disease.

Why is it important to treat?

It is important to remove the bacteria from the exposed root surface. This aids in better maintenance of oral hygiene.
It can lead to tooth loss if left untreated.

Treatment options vary

Resective:
1. Furcationplasty,
2 Root amputation,
3 Root resection,
4 Hemisection
5 Tunnelling

Regenerative
1 PRF(Platelet rich fibrin)
2 GTR(Guided tissue regeneration)
3 Bone grafts

GUIDED TISSUE REGENERATION (GTR) FOR FURCATION INVOLVEMENT

Patient presented with chief complaint of food impaction in left upper back tooth region (26 , 27). On clinical examination the probing depth was 5mm with grade II furcation involvement irt 26. Gingival recession – Height 3 mm and width 4mm.

After oral prophylaxis and subgingival debridement the surgical procedure was planned
