The aim of this study was to investigate the effect of bone augmentation simultaneous to implant removal on the prognosis of reimplantation at the same sites, providing recommendations for management strategies after failed implant removal.
The study aims to compare the radiographic and clinical indicators between bone augmentation simultaneous to implant removal and natural healing after implant removal, thus evaluate the effect on the prognosis of reimplantation. At the same time, patients with implant failure were also retrospectively collected to investigate the factors influencing the prognosis of bone healing and reimplantation after implant failure.

| Measure | Description | Time Frame |
|---|---|---|
| Ridge Height (RH) | Two reference lines were established for the radiological analysis: the longitudinal axis of the implant and a line perpendicular to this axis and tangential to a reference point (sinus floor in the maxilla and mandibular base in the mandible).Ridge height (RH) in mm, defined as the distance between the tangential reference line and the most coronal point of the bone crest, assessed buccal (B-RH) and lingual (L-RH). | Before implant removal and 6 months after implant removal |
| Measure | Description | Time Frame |
|---|---|---|
| Ridge Width (RW) | Two reference lines were established for the radiological analysis: the longitudinal axis of the implant and a line perpendicular to this axis and tangential to a reference point (sinus floor in the maxilla and mandibular base in the mandible).Ridge width (RW) in mm, recorded at 1, 3, and 5 mm from the bone crest. In the event of discrepancy between the buccal and lingual bone crests, the most apical one was chosen as reference. |
