简要总结
Conventional loading protocol following implant placement 3 -6 months is considered the gold standard. However, early loading following 2 months after implant placement decreases the time and had a good survival rate.
详细描述
The conventional loading protocol presented involves healing period of 3 -6 months. A healing period without stress was recommended in the order to present better survival rate. This loading protocol was developed in the time when micro- and macro design of implant surface was machine produced. Early loading of dental implants within 2 months following placement on healed posterior mandible showed 100% survival rate for five years follow up, with uneventful crestal bone loss. The lack of difference between conventional loading 6 months following implant placement and early loading could be explained by the fact that even if the crowns were not put in direct occlusion, patients used them functionally when chewing. The most relevant factor which may explain the positive results obtained in this trial is the high insertion torque at implant placement.
