NCT03357705

Brief Summary

The aim of the present study is to evaluate the effectiveness of different alveolar preservation procedures performed at the time of extraction of the first or second upper molar in avoiding a maxillary sinus elevation or at least limiting the size, to allow the insertion of dental implants. The residual bone height will be radiographically evaluated on the sinus sinus floor at the time of extraction and after 6 months by comparing the cases where alveolar preservation is performed using a nanocrystalline synthetic hydroxyapatite graft (group A) with cases where the procedure of alveolar preservation is performed using bovine collagen sponge (group B).

Eligibility Criteria

Age19 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • indication for extraction of the first or second upper molar, based on a thorough diagnosis and treatment plan;
  • "three-rooted" anatomy of the first or second upper molar to be extracted so that it can have an inter-radicular septum that allows a precise measurement of the height of the bone ridge from the septum itself and from the walls of the 3 alveoli to the floor of the maxillary sinus;
  • Extraction of intercalate molar or last arch element;

You may not qualify if:

  • Anatomy of the molar with unique root or fused roots
  • contextual extraction of the molar and one or more contiguous elements
  • apical lesions with a diameter of\> 3 mm or cystic lesions with respect to the element to be extracted
  • root fracture which has produced resorption or bone fenestration
  • \) acute myocardial infarction in the last six months; 2) uncontrolled clotting disorders; 3) uncontrolled diabetes (HBA1c\> 7.5%); 4) radiotherapy in the head / neck district for the last 24 months; 5) immunocompromise (eg HIV infection or chemotherapy over the last 3 years); 6) treatment in progress or with bisphosphonates via e.v .; 7) autoimmune diseases in chronic therapy with methotrexate or other immunosuppressive drugs; 8) allergy to bovine collagen; 9) psychological or psychiatric problems; 10) abuse of alcohol or drug use; 11) uncontrolled periodontal disease;
