‘Dentin Block’ as an alternative to bone regeneration
jeudi 14 juin 2018
Researchers from Belgium and Chile recently conducted a study examining the use of a ‘Dentin Block’ in an alveolar ridge preservation test model. The aim of the study was to test the clinical outcomes of the block as an alternative for bone regeneration.
Bone graft materials are important components for preparing and regenerating implant sites. However, there currently isn’t a viable graft material which has the same properties as autogenous bone. This study used a graft material composed of autogenous dentin mixed with L-PRF and liquid fibrinogen (Dentin Block) and examined its regenerative capabilities.
To test the ‘Dentin Block’, ten extraction sockets received the graft and were clinically examined after four to six months. All sites showed positive and progressive bone formation results with no traces of dentin observed in 40% of sites at follow-up.
The results showed that the dentin from the block had been replaced with new bone without any adverse tissue reactions and with favourable rates of bone formation. The authors note that longer-term research is required, though this promising result could have significant clinical implications, owing to the material’s regenerative potential, low risk of adverse effects and feasible acquisition.
This study was presented as an e-poster at the 2017 EAO Congress.
