About this study

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

Primary outcomes

  1. Vertical dimensional alterations of the alveolar ridge, after tooth extraction.

    Time frame: 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).

  2. Horizontal dimensional alterations of the alveolar ridge, after tooth extraction.

    Time frame: 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).
