This article is about the use of a laterally repositioned interdental multiple papilla flap to augment the attached gingiva on a tooth with an abnormal root surface.

 

A 35 years old male non diabetic, non smoker, presented with recurrent gingival inflammation on a lower cuspid. After several recall visits an enamel pearl was detected on the root surface and surgical treatment was planned.

The flap is pulled by the muscles that run in a mesiodistal direction until it is positioned in the area of the recipient teeth. The interproximal papillae are moved over the root surfaces of adjacent teeth. Sling sutures anchored to the periosteum are performed around individual teeth, and horizontal sutures help in maintaining flap adhesion to underlying surfaces.

Img. 5 – The flap is moved laterally from 32 and sutured on 33, with a sling horizontal suture to promote adaptation of the flap to the periosteum. The papillae between 33-34 and 34-35 are moved distally and similarly sutured. 2-years follow-up.

Conclusions

After proper diagnosis and adequate surgical treatment, elimination of gingival inflammation, augmentation of attached gingiva and root coverage can be obtain long term.
