Extra-short vs. Non-extra-short Dental Implants Splinted on the Same Prosthesis

This study compares extra-short dental implants (less than 6.5 mm) and standard-length implants (6.5 mm or more) when they are both used to support the same dental bridge in people with bone loss in the jaw. In areas where the jaw bone is not deep enough for standard implants, shorter implants may be an option — this study examines how well they perform when combined with longer implants. You may be eligible if: - You are 18 years or older - You need a fixed dental bridge supported by a mix of short (under 6.5 mm) and standard (6.5 mm or longer) implants - Your prosthesis involves 2 to 4 implants - You have had a recent cone-beam CT scan (CBCT) You may NOT be eligible if: - You smoke more than 10 cigarettes per day - You need a complete (full) denture (all teeth in an arch) - You need a single-tooth (unitary) implant prosthesis Talk to your doctor to see if this trial is right for you.
