Clinical Trial 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.

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

Outcome
Type Measure Description Time frame Safety issue
Primary Vertical dimensional alterations of the alveolar ridge, after tooth extraction. 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). 4 months
Primary Horizontal dimensional alterations of the alveolar ridge, after tooth extraction. 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). 4 months
