Abstract |
Nowadays, it seems like that the concept of the early loading protocol has been intruded between the concept of the immediate loading supported by advanced clinicians and the concept of the conventional loading supported by the prudent clinicians. In particular, the stability dip, which is found to occur usually at 4~6 weeks after dental implant placement because the decrease of the primary mechanical stability is not compensated by the increase of the secondary biologic stability, is frequently pointed out as one of the major causes of early loading failure. In this article, based on our recent clinical investigation about the crestal bone preservation effect of the early loaded NanoTiteTM Tapered Certain Prevail(R) (Biomet 3i, USA), the concept of the early loading is revisited. In addition, various methods to overcome the stability dip are reviewed as the oral and maxillofacial surgeon's view point. |
