(MDIs) are small diameter dental implants. Dental implants may be split into two separate categories based on the diameter of the device. Small diameter dental implants, most often referred to as ‘Mini Implants’, are those with a diameter less than three millimeters (3mm.) Likewise, standard or conventional implants are those implants larger than 3mm in diameter, but most commonly 4-5mm. As a rule of thumb, Mini Dental Implants are at least half the price of conventional implants and sometimes a quarter of the price of conventional implants. Mini implants can be used in orthodontics to facilitate tooth movement.
