About

The aim of the present randomized controlled trial (RCT) was to evaluate the efficacy of different alveolar ridge preservation (ARP) techniques on hard tissue dimensional alterations after tooth extraction, based on clinical measurements.

Full description

Thrirty-six patients were randomly assigned in four treatment groups: A) freeze-dried bone allograft (FDBA) covered with collagen sponge (CS), B) FDBA covered with free gingival graft (FGG), C) demineralized bovine bone mineral xenograft (DBBM) covered with FGG and D) FGG without socket grafting. Clinical measurements were performed immediately after tooth extraction and 4 months later. The related outcomes pertained to both vertical and horizontal assessment of bone loss

Alveolar ridge preservation with particulated allograft covered with collagen sponge.
Experimental group
Description:
Alveolar ridge preservation after tooth extraction. Freeze-dried bone allograft (FDBA) was applied in the socket immediatelly after tooth extraction and it was covered with collagen sponge (CS).
Treatment:
Other: Alveolar ridge preservation
Alveolar ridge preservation with particulated allograft covered with autogenous soft tissue punch
Experimental group
Description:
Alveolar ridge preservation after tooth extraction. Freeze-dried bone allograft (FDBA) was applied in the socket immediatelly after tooth extraction and it was covered with free gingival graft (FGG).
Treatment:
Other: Alveolar ridge preservation
Alveolar ridge preservation with particulated xenograft covered with autogenous soft tissue punch
Experimental group
