As of 2015, mini implants can cost $300 to $900 per fixture, according to The Dental Implant Center. Mini implants are about 2 millimeters in diameter and have limited application.
Mini implants can be used as supporting structures for individual teeth or can be inserted as a grouping in order to buttress a denture, according to The Dental Implant Center. This is in contrast to standard implants, which are usually about 3 to 6 millimeters in diameter. Standard implants cost from $1800 to $2,500 per tooth and can be arranged in a variety of abutments for customized connection to teeth.
