Efficacy of MimetikOss in Alveolar Ridge Preservation Previous to Implant Placement

Inclusion Criteria: * \>18 years old. * Able to sign an informed consent form. * Patients in need of socket preservation presenting 4 wall defects on premolar and molar zone in the maxilla or in the mandible. * Healthy extraction site (no infected walls). * The height of root molar bone support must be \> 6 mm. The height of root molar bone support plus the bone height between the most apical root part and the sinus floor must be \> 3 mm. As described in the picture below. Molar roots must be surgically separated previous to extraction * Only 4 walled defects are included (3mm max of difference between buccal and lingual plate height). * Presence of opposite occlusal dentition with natural roots in the area intended for extraction and implant placement. * Natural roots are adjacent to implant site. * If patient presents more than 1 defect that could be included in the study, only one will be part of the study, the other sites will be treated with the standard of care. * Patient in good physical health. * The subject is willing and able to comply with all study-related procedures (such as exercising oral hygiene and attending all follow-up procedures). * Full-mouth bleeding score (FMBS) lower than 25%. * The subject is suitable for a 2-stage surgical procedure. Exclusion Criteria: * Patients with premolar extraction due to the root fracture that present infected two wall type defect. * Patients presenting the defect in the molar and/or premolar region of the maxilla with th…
