Outcome Measures
Primary Outcomes (2)
Marginal Bone Loss
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.
up to 12 months
Implant stability
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
up to 12 months
Study Arms (2)
Immediate implant placement
EXPERIMENTALEarly implant placement
ACTIVE COMPARATORInterventions
Tooth extraction was performed atraumatically on one side, followed by immediate implant placement, right after extraction.
The tooth was extracted, and the implant was placed four weeks later (early placement).
