Overview
Brief Summary
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.
Detailed Description
A three-arm randomized clinical study will be conducted: * Group 1 (study group): Ridge preservation with "Pontic-shield" technique. * Group 2 (positive control): Ridge preservation with deproteinized bovine bone and porcine collagen membrane after tooth extraction. * Group 3 (negative control): Tooth extraction only (fresh socket). A cone-beam computed tomography will be performed prior to tooth extraction and 4 months postoperative. Radiographic changes between before and after intervention will be evaluated to asses the effectiveness of "Pontic-shield" technique.

Eligibility Criteria
Inclusion Criteria
- •Patient from 18 to 80 years old
- •Patients who sign the informed consent
- •Need to perform extraction from second premolar to second premolar in maxilla and mandible
Exclusion Criteria
- •Tobacco consumption (more than 10 cigarettes per day)
- •Severe systemic disease ( ASA III or IV - American Society of Anaesthesiology)
- •Drug use that could interfere with alveolar bone healing
- •Active periodontal disease
- •Acute or chronic apical pathology of the tooth
Outcomes
Primary Outcomes
Bone resorption
Time Frame: From the day of the extraction to 4 months after
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.
Secondary Outcomes
- Satisfaction assessed by visual analogue scale (VAS)(From the day of the surgical procedure to the seventh-day)
