ITI Research Grant Application 2021-1612: Alveolar ridge preservation with immediate or delayed implant placement: a multicenter randomized controlled trial

Alveolar ridge preservation (ARP) can be combined with immediate implant placement (IIP) or delayed implant placement (DIP). Both approach have specific advantages and disadvantages, yet RCTs have not been published on the need for soft tissue augmentation.

The hypothesis is that ARP + IIP reduces the need for soft tissue augmentation since the peri-implant mucosa can be immediately supported with a provisional crown. In contrast, ARP + DIP allows the tissues to collapse. The primary objective of this multicenter RCT is to compare ARP+IIP with ARP+DIP with respect to the need for soft tissue augmentation 6 months after ARP.
