Gedetailleerde beschrijving
12 patients were included in this split-mouth RCT. In test sites a horizontal GBR procedure was performed using a collagen membrane with a graft consisting of 50% autogenous bone and 50% DBBM. In control sites a collagen membrane was used, with a graft consisting of an LPRF block. This was left to heal for 9 months. Subsequently an implant was placed. At time of implant placement a bone biopsy was taken. After 4 months of osseointegration the abutment connection was performed. 1 year after loading of the implants a final check was done. CBCT scans were taken at intake, immediately after reconstruction, 9 months after reconstruction, before implant placement and 1 year after loading of the implants.
Primary outcome measure is the bone volume as measured on the CBCT scans. Secondary outcome measures are bone quality in the biopsy, buccal bone thickness around the oral implant, number and type of complications, cumulative survival rates of the implants 1 year after loading.
