Outcome Measures
Primary Outcomes (1)
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
Secondary Outcomes (8)
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
- +3 more secondary outcomes
Study Arms (2)
Bone augmentation simultaneous to implant removal
EXPERIMENTALPlacement of bone substitutes in the socket simultaneous to implant removal, and reimplantation is performed after 6 months of healing.
Natural healing after implant removal
NO INTERVENTIONInterventions
Placement of bone substitutes in the socket simultaneous to implant removal, and reimplantation is performed after 6 months of healing.
