Marginal Bone Loss
Conditions
Brief summary
This study aims to determine the differences in implant stability and measurement of bone loss near implants between two different healing approaches used for teeth replacement in the front part of the upper jaw.
Interventions
PROCEDUREImmediate implant placement
Tooth extraction was performed atraumatically on one side, followed by immediate implant placement, right after extraction.
PROCEDUREEarly implant placement
The tooth was extracted, and the implant was placed four weeks later (early placement).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Marginal Bone Loss | 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 | 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 |
