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
