结局指标
主要结局
Marginal Bone Loss
时间窗: up to 12 months
Cone beam computed tomography (CBCT) scans were obtained at the time of final restoration and post-placement. Measurements were made (in mm) from the implant platform to the most coronal bone level using OnDemand3D software. Each scan was oriented to align the implant with the axial plane. Measurements were performed by a single calibrated examiner to a precision of 0.01 mm.
Implant stability
时间窗: up to 12 months
Implant Stability Quotient (ISQ) values were measured using Osstell. To ensure accuracy, the probe was positioned at a 90° angle and 3 mm above soft tissue level, as recommended in previous protocols. Osstell's patented technology uses the ISQ scale, with values ranging from 1 to 100, where higher values indicate greater stability
