The 'two-phase' dental implant remains in some cases an effective solution when it comes to a small segment of one or two teeth. To follow up on success and failure studies carried out for several years, we note that the dental implant in two phases is less effective during complete restorations or large segments from 3 teeth. On the other hand, it remains a good solution when replacing an individual tooth.
The traditional dental implant is placed in the spongy part (internal and central part). It is so-called because of its sponge structure which offers resistance to crushing. This part of the bone tissue has the defect of atrophy when it is no longer put under the constraint of a force (The chewing force of a tooth or that of a dental implant). For this reason, in traditional dental implantology, it is necessary to restore volume by a bone graft in the event of significant bone loss.
