Osseointegration of Mobile Posterior Single-Tooth Implants with SLA Surface: Report of 2 Cases

The conditions for achieving osseointegration of endosseous implants have been well established. The criteria that validate this result concern the physical properties of the implant (eg, material, surface properties), its controlled loading, and its primary stability. Theory regarding primary stability has evolved in recent years. Two clinical cases of totally mobile yet eventually successful sandblasted, large-grit, acid-etched implants serve as illustrations of the possible success of implants deprived of primary stability. In certain circumstances, and if certain recommendations are enforced, it may be possible to consider the preservation, with success, of implants that are completely mobile.
