45 extraction, and debridement of the inflammatory tissue.

Filling with Geistlich Bio-oss® (small granules 0.25-1mm)

Buccal bone wall replaced by Geistlich Bio-gide® (13×25mm) double-layer

Geistlich Bio-gide® is sutured with a modified cross-mattress suture with 4-0 PTFE, allowing optimal adaptation between the borders of the soft tissues and the collagen matrix

Situation after 17days after surgery

Note the epithelium has become stretched
