Zirconia dental implants for missing premolars

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial involves 24 patients with missing premolar teeth who will be randomly assigned to receive either tissue-level or bone-level zirconia implants. The implants will be 10-mm long and 4-mm wide, and their stability will be assessed using the International Stability Quotient (ISQ) device. After a three-month healing period, ceramic crowns will be placed on the implants, and various parameters related to implant survival and peri-implant health will be monitored over a period of 1, 3, and 5 years.
