Overview
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.
Detailed description
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.
Interventions
- Procedure 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.
Primary outcome measures
- Ridge Height (RH) [Time frame: Before implant removal and 6 months after implant removal]
Secondary outcome measures (8)
- Ridge Width (RW) [Time frame: Before implant removal and 6 months after implant removal]
- Bone Plate Thickness (BPT) [Time frame: Before implant removal and 6 months after implant removal]
- Bone Mineral Density(BMD) [Time frame: 6 months after implant removal]
- Inserting Torque(IT) [Time frame: Replantation surgery]
- Implant Survival Rate(SVR) [Time frame: 6 months and 12 months after restoration]
- Probing Depth [Time frame: 6 months and 12 months after restoration]
- Bleeding On Probing（BOP） [Time frame: 6 months and 12 months after restoration]
- Marginal Bone Loss(MBL) [Time frame: 6 months and 12 months after restoration]
