About this trial
Alveolar bone resorption after dental extraction frequently leads to situations in which long-term function and esthetic success of rehabilitations with dental implants is a challenge. "Pontic-shield" has been described as an alternative technique to maintain alveolar ridge after tooth extraction.
The aim of this study is to analyze the effectiveness of "Pontic-shield" technique in alveolar ridge preservation comparing to fresh socket and ridge preservation using deproteinized bovine bone and a porcine collagen membrane.
