Can Ridge Preservation reduce vertical changes and thereby prevent sinus lift? For the first time, this question has been investigated in a prospective randomized clinical trial.
Verena Vermeulen | Switzerland
The trial with 40 consecutive patients in need of tooth extraction had two groups.
After 6 months, bone height was measured radiographically. Those patients who had chosen implant therapy (14 in each group) received an 8 mm implant if bone height was enough. If not, crestal or lateral sinus lift was carried out.
Summary of the study results
"Alveolar ridge preservation in the posterior mandible maintained the vertical bone height more efficiently and resulted in less need for sinus augmentation procedures at 6 months compared to spontaneous healing. […] Based on these findings, ARP would be strategically recommended to clinicians with the object of decreasing the invasiveness and complexity of implant treatment in the maxillary posterior area."
