简要总结
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.
详细描述
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.

研究组 & 干预措施
Bone augmentation simultaneous to implant removal
Placement of bone substitutes in the socket simultaneous to implant removal, and reimplantation is performed after 6 months of healing.
干预措施: bone augmentation simultaneous to implant removal (Procedure)
Natural healing after implant removal
结局指标
主要结局
Ridge Height (RH)
时间窗: Before implant removal and 6 months after implant removal
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).
次要结局
- Marginal Bone Loss(MBL)(6 months and 12 months after restoration)
- Ridge Width (RW)(Before implant removal and 6 months after implant removal)
- Bone Plate Thickness (BPT)(Before implant removal and 6 months after implant removal)
- Bone Mineral Density(BMD)(6 months after implant removal)
- Inserting Torque(IT)(Replantation surgery)
- Implant Survival Rate(SVR)(6 months and 12 months after restoration)
- Probing Depth(6 months and 12 months after restoration)
- Bleeding On Probing（BOP）(6 months and 12 months after restoration)
