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.

Treatments tested in this trial
"Pontic-shield" technique
Procedure/SurgeryA 1mm thick fragment of the vestibular aspect of the root will remain after extraction (partial extraction)
Alveolar ridge preservation
Procedure/SurgeryParticulate deproteinized bovine bone and porcine collagen membrane will be placed after tooth extraction
Treatment groups
30 Participants
are divided into 3 treatment groupsGroup A: Study groupExperimental treatment 1 intervention
Group B: Positive control (ridge preservation)Active comparator 1 intervention
Group C: Negative control (fresh socket)No intervention 0 interventions
Trial outcomes
Primary outcomes
1
Bone resorption
Radiographic changes between preoperative (prior to tooth extraction) and postoperative (4 months after intervention) will be analyzed. This variation will be assessed by measuring changes in width and height (in millimeters) of the socket by superimposition of CBCT before and after the intervention.
Time frame
From the day of the extraction to 4 months afterSecondary outcomes
1
Satisfaction assessed by visual analogue scale (VAS)
Postoperative pain with visual analogue scale (VAS) from 0 (no pain) to 10 (maximum pain)
Time frame
From the day of the surgical procedure to the seventh-daySponsors and contacts
