Comparing patient satisfaction and bone changes with zirconia and titanium implants in dentures

Assessment of Patient Satisfaction and Crestal Bone Changes Around One-piece Zirconia and Titanium Implants in Mandibular Implant-Retained Overdenture: A Randomized Clinical Trial

Not applicable Interventional Ain Shams University · NCT06643975

This study is testing whether men aged 50 to 60 feel more satisfied and experience different bone changes with zirconia or titanium dental implants in their dentures.

What this trial studies

This clinical trial evaluates the differences in patient satisfaction and crestal bone changes between one-piece zirconia and titanium dental implants used in mandibular overdentures for completely edentulous male patients aged 50 to 60. The study involves a randomized approach where participants will receive either type of implant and will be monitored for 12 months following the placement of the definitive prosthetic. The goal is to determine if there are significant differences in outcomes between the two implant materials.

Who should consider this trial

Good fit: Ideal candidates are male patients aged 50 to 60 with moderately developed mandibular residual ridges and sufficient bone height for implant placement.

Not a fit: Patients with systemic diseases affecting bone quality, poor oral hygiene, or those who smoke heavily may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved patient satisfaction and better bone health outcomes for individuals receiving dental implants.

How similar studies have performed: Previous studies have shown varying success with different implant materials, but this specific comparison of zirconia and titanium in this context is relatively novel.

Eligibility criteria

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.
