Purpose: The purpose of this study is to evaluate the immediate or early loading on partial or single implant cases with RFA measurements.
Materials & Methods: forty-four tapered designed implants(41 replace select?, 3 Tapered screw vent? implants) were placed in 10 patients of partial or single cases for immediate or early loading in all jaw lesions. The guidelines for early or immediate loading were the peak insertion torque more 20Nm during implant insertion and RFA ISQ values than 45 immediate after implant insertion. Apart from clinical and radiographic examinations, the patients were followed with RFA at placement, measured again every 2weeks until 12weeks and measured at 12 months. Statistical analyses were carried out to study the possible differences between the time of implant placement.
Results: Three implants failed. Two of them seemed to be failed because of surgical technique mistake and one was a prosthesis of overloading due to provisional prosthesis fracture. RFA values were pretty stable during all periods. But there seemed to be significant between initial v.s. final RFA values.
Conclusion: Within the limitations of this study, tapered implants with high initial stability can be used as immediate and early loading on various jaw regions.
