Mini implants are smaller in diameter, ranging from 1.8mm to 3.3mm, while conventional dental implants are larger. Mini implants are often used to stabilize dentures or support smaller restorations in areas with limited bone volume, while conventional implants are more commonly used for single-tooth replacements or larger restorations. The success rate has reached as high as 97% over a five-year period and 92% over a ten-year period.
