Any blinded information will be available then. Immediate Implantation for Molar Replacement with Pre- Extractive
Objective:
This prospective clinical case series investigates whether pre-extractive interradicular implant bed preparation for immediate implant placement in molar sites provides technical advantages with regard to sufficient implant primary stability and correct implant positioning without being disadvantageous in terms of survival and success rates.
Methods:
27 untreatable molars were replaced by immediate implants following pre-extractive interradicular implant bed preparation. Implant survival and success were evaluated. Success was defined by sufficient implant primary stability for transmucosal healing (final insertion torque value ≥ 15 Ncm), correct three-dimensional implant position enabling an occlusally screw-retained restoration, peri-implant probing depths ≤ 5 mm, and absence of clinical signs of inflammation two years after immediate implant placement.
Results:
Survival rate two years after immediate implant placement was 100%. Transmucosal healing as well as occlusally screw-retained restorations were achieved in all cases. The success rate was 96.3% due to one patient presenting a biological complication with increased peri-implant probing depths and clinical signs of inflammation.
Conclusion:
The proposed clinical protocol of pre-extractive interradicular implant bed preparation in molar sites provides advantages in terms of achieving implant primary stability for transmucosal healing and correct three-dimensional implant position, without being disadvantageous with regard to survival and success rates two years after treatment.
