Alveolar Ridge Preservation Techniques After Tooth Extraction
- Conditions
- Alveolar Bone Loss
- Interventions
- Other: Alveolar ridge preservation
- Registration Number
- NCT04934813
- Lead Sponsor
- National and Kapodistrian University of Athens
- Brief Summary
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.
- Detailed 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

Group Intervention Description Alveolar ridge preservation with particulated xenograft covered with autogenous soft tissue punch Alveolar ridge preservation Alveolar ridge preservation after tooth extraction. Demineralized bovine bone mineral xenograft (DBBM) was applied in the socket immediatelly after tooth extraction and it was covered with free gingival graft (FGG).

Alveolar ridge preservation with particulated allograft covered with autogenous soft tissue punch Alveolar ridge preservation 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).

No bone graft was applied and the socket was covered with free gingival graft (FGG).
- Primary Outcome Measures
Name Time Method Horizontal dimensional alterations of the alveolar ridge, after tooth extraction. 4 months Assessment of the alteration of the alveolar ridge width after different alveolar ridge preservation techniques, based on clinical measurements. Clinical measurements were carried out immediately after tooth extraction and 4 months later. Distances in those clinical measurements were recorded in 0.1 mm increments, using a digital calliper (Logilink digital caliper WZ0031).
Vertical dimensional alterations of the alveolar ridge, after tooth extraction. 4 months Assessment of the alteration of the alveolar ridge height after different alveolar ridge preservation techniques, based on clinical measurements. Clinical measurements were carried out immediately after tooth extraction and 4 months later. Distances in those clinical measurements were recorded in 0.1 mm increments, using a digital calliper (Logilink digital caliper WZ0031).
