Procedure: Bone curettage + PRF
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 ]
  • The appearance of osteochemonecrosis during the follow-up period [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The characteristics of the received BP treatment: starting date of ongoing treatment, accumulated dose, type of BP, administration route [ Time Frame: 1 year ] [ Designated as safety issue: No ]
