Why shouldn’t we, as responsible professionals make oral implantology less invasive and as simple as possible? This will not only lower costs, it would decrease clinical time for the doctor and recovery time for the patient. On top of it, such procedures have been proven to be relatively pain free.

(6) One reason why mini- implants can be loaded immediately as a matter of routine is because there is minimal trauma to the bone. As such, the process of osseointegration begins immediately on implantation. There is no transitional margin of necrosis between the implant and bone which is found in conventional implant placement. Also, because the mini- implant is small, the healing challenge to the surrounding tissue is correspondingly small and the tissue heals rapidly and almost immediately.
The healing challenge of the surrounding tissue in the case of the conventional implants is much more and requires a longer time, thus immediate loading of conventional implants often is less successful.

(7) The actual surface area of minis are actually comparable to the surface area of conventional size dental implants. This is because minis are usually place deeper and therefore longer than conventionals, thus increasing its effective surface area available for osseointegration.
  • A conventional sized dental implant 4mm diameter and 10mm long has a surface area of about 125 sq mm.
  • A reduced diameter dental implant 2.5mm diameter and 10mm long has a surface of about 80sq mm.
  • A reduced diameter dental implant 2.5mm diameter and 13mm long has a surface of about 100sq mm.
  • A reduced diameter dental implant 2.5mm diameter and 16mm long has a surface of about 125 sq mm.
  • A reduced diameter dental implant 2.5mm diameter and 19mm long has a surface of about150 sq mm.

Thus  a mini that is 2.5mm diameter and 16mm long in its threaded area has a surface area equivalent to a conventional sized dental implant 4mm diameter and 10mm long.
In my experience, this length is one of the most common mini used and very often 2 minis are used to restore one molar. Two minis 2.5mm diameter and 10mm long has a surface area of 160 sq mm! This is more than that of a conventional 4mm diameter and 10mm long. Two minis 10mm long is more than adequate for one molar since very often one molar is restored by a conventional that has a surface area of only 125 to 150sq mm.
