Procedure: Bone curettage alone

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Contribution of Platelet Rich Fibrin (PRF) After Tooth Avulsion in the Prevention of Healing Delay and of Jawbone Osteochemonecrosis Induced by Bisphosphonates

Further study details as provided by Centre Hospitalier Régional Metz-Thionville:

Primary Outcome Measures:
  • Delay in cicatrisation at week 8 [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
