Role of mechanical compression on bone regeneration around a particulate bone graft material: an experimental study in rabbit calvaria

Abstract

Increasing the compressive force applied to bone graft particulate used to fill small defects created in rabbit calvaria appears to be beneficial.

Influence of wound closure on the volume stability of particulate and non‐particulate GBR materials: an in vitro cone‐beam computed tomographic examination. Part II

“…†Statistically significant. Benic et al 2015) and low compression of the graft (increased space between particles) (Romanos et al 2015) may be some of the reasons, which could explain why graft particles become embedded in a fibrous tissue instead of forming new bone. Consequently, the combination of a granular bone substitute plus an additional layer of soft-block bone substitute aims to achieve a stable coagulum with high potential for bone regeneration around the implant surface while retaining as much volume as possible in the buccal and occlusal areas.…”

Infected tooth extraction, bone grafting, immediate implant placement and immediate temporary crown insertion in a patient with severe type-B hemophilia

“…A 4.1 mm diameter implant with 12 mm length facilitated the haemostasis of the apical bone and the middle and apical thirds around the implant body. Graft particles were embedded in TXA to stabilise the fibrin clot and to create a more stable and malleable grafting paste11 12; afterward, the graft was compressed to provide additional haemostasis, stabilise the graft particles by reducing the voids between particles and to facilitate the fibrin clot contact with all the surfaces 13 14…”

“…Residual bleeding coming from the remnants of the socket walls was controlled by filling the gap (space between the implant body and implant bed produced by the differences between the root anatomy and implant geometry) with a particulate bone graft (Bone Ceramic, Straumann, Basel, Switzerland) previously embedded in TXA11 12 (Amchafibrin, Meda Farma) and packed with 200g compression force with a bone condenser 13. The graft particles were condensed against the base and walls of the socket until the particles were compacted, stabilised and filled with a blood coagulum 14…”

Concepts for prevention of complications in implant therapy

“…Bone grafting is a current requirement, and improvement of surgical skills is a prerequisite, providing the foundation for hard‐tissue stability. Recent studies show that particulate bone‐grafting materials should be compressed as formation of new bone is more effective under compression . Empirical approaches need to be tested to provide evidence for clinical practice success.…”
