Comparing narrow and standard dental implants for patients with bone loss in the jaw

Radiographic Evaluation of Crestal Bone Loss Around Narrow Diameter Implants Versus Standard Diameter Implants in Conjunction With Bone Augmentation in Horizontally Deficient Posterior Mandibular Partially Edentulous Sites: A Randomized Clinical Trial

Not applicable Interventional Cairo University · NCT06221306

This study is testing if narrow dental implants can work just as well as standard ones for people with bone loss in their jaw, to see if they can avoid extra surgeries.

What this trial studies

This study investigates the effectiveness of narrow diameter implants (NDIs) compared to standard diameter implants (SDIs) in patients with horizontal bone loss in the posterior mandible. The aim is to determine if NDIs can eliminate the need for additional bone augmentation procedures, which often increase treatment time, costs, and patient morbidity. Participants will be assessed for their eligibility based on specific criteria related to their dental and medical history. The study will focus on the survival rates and complications associated with both types of implants.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with edentulous posterior mandible sites requiring implant placement and sufficient bone height and width.

Not a fit: Patients with systemic conditions affecting bone metabolism or those with habits that could jeopardize implant longevity may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a less invasive and more cost-effective solution for patients needing dental implants in areas with bone loss.

How similar studies have performed: Previous studies have shown promising results for narrow diameter implants, indicating potential success for this approach.
