Sorting through your choices for repairing these deep-seated defects


Technique for guided tissue regeneration

1. Expose the intrabony defect with a mucogingival flap (Photos 6 and 7).

2. Use a thin curette to clean accessible granulation tissue, calculus and plaque between the root and alveolus. Do not remove clot formation (Photo 8).

3. Apply the chosen membrane over the cleaned defect (Photo 9).

4. Follow the manufacturer's directions concerning suturing in the membrane (some do not require suturing).
