About

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

Enrollment: 20 estimated patients

Sex: Male

Ages: 50 to 60 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Male patients
• The age range of 50 to 60 years old (average of 55).
• 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

Exclusion criteria

• Heavy smokers of more than 10 cigarettes a day
• Poor oral hygiene.
• Patients with temporomandibular joint disorders(TMD),
• Patients suffered of xerostomia,
• Patients exhibited Para-functional habits, or recent extractions were excluded.
• Patients with systemic diseases that might affect bone quality or quantity, or retard healing of the surgical wounds were excluded.
• Patients receiving intravenous forms of bisphosphonates.
• Patients who have had radiation therapy to the head and neck region.
• Patients with existing implants in the jaws
• Patients with previous bone grafting in either the maxillary or mandibular jaws.
