Details and patient eligibility

About

The purpose of the study is to test whether a two-piece zirconia implant is as reliable in the indication of immediate implant placement as a standard titanium implant.

Enrollment: 33 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

8. Teeth with removable periapical lesions are included.

Exclusion criteria

Primary exclusion criteria are as follows:

1. parafunctional habits;

2. active periodontitis;

3. smoking;

4. pregnancy;

5. acute or chronic medical conditions for which implant therapy has always been considered a contraindication: uncontrolled diabetes (HbA1c >8.0%), mucosal disease, untreated periodontitis, immunological disorders, active malignancy, alcoholism, condition after radiation therapy to the head and neck area and antiresorptive therapy.
