• 1 other identifier: P-15/568
• Study Type: observational
• Target: 8
• Locations: 0 countries
• Sites: N/A

Brief Summary

The aim of this study is to propose a modification of the original periostal pocket flap technique consisting in replacing the xenograft by a conglomerate which contains autologous bone obtained from the future implant site through biological drilling technique and PRGF (Plasma Rich in Growth Factors)

Conditions

Bone Regeneration

Keywords

Periostal Pocket Flap Technique; PPFT

Outcome Measures

Primary Outcomes (1)

• Volume of bone augmentation

  Volume of bone augmentation of the surgical sites was measured in the postoperative parasagittal CT scans using a region of interest (ROI) containing the entire bone box regenerated area using the closed polygon tool of the OsiriX software

  4 months

Study Arms (1)

unique group

After local anesthesia, a full thickness flap was elevated from the lingual wall and a partial thickness flap was performed in the buccal one. After that, the buccal periosteum was detached and dental implants were placed following the biological drilling protocol, getting autologous bone particles from the implant site. Patient's blood collection was performed and the plasm obtained was poured down on a sterile container and mixed with autologous bone particles collected previously during the drilling procedure. Finally the graft was placed in the pocket prepared previously and the surgical wound was sutured in two planes.
