The definition of immediate loading includes the occlusion with the tooth in the mandibular counterpart. Already in 1979 it had been shown that with these conditions, the plant of the tooth with fixing screw occurred successfully. Many experimental studies have shown that the immediate load with respect to threaded implants do not comport necessarily the healing of the fibrous tissue. However, over time it develops a bone contact which can be assimilated to that which develops with conventional plants. The plants found in humans with adjacent bone have confirmed these experimental results both as regards the jaw that for what concerns the maxillary top. It was found a bone-implant contact in more than 93% of intra-osseous parts of the plant, and there was no statistically significant difference in 'ost eointegrazione of immediately loaded implants in smokers.
