Overview
This interventional randomized clinical trial study is conducted to assess patient satisfaction and crestal bone changes around one-piece Zr and Ti Implants in mandibular implant-retained overdenture in completely edentulous male patients in the age group between (50-60)years old to know if there will be a significant difference between the two types of dental implants through 12 months after the definitive prosthetic loading
Eligibility
Inclusion Criteria:

- moderately developed mandibular residual ridges, covered with healthy mucosa, firmly attached to the underling bone and with average mucosal thickness (2-3) mm.
- At least 12 mm of vertical bone height in the mandible allowing for placement of a 10 mm implant (2 mm safety distance to inferior alveolar nerve).
- Patients were selected with Angle class-I maxillomandibular relationship with sufficient inter-arch space (13-15mm
