LPRF Block vs. DBBM in Horizontal Bone Reconstruction
Horizontal Guided Bone Regeneration: LPRF Block vs. a Mixture of Autogenous Bone With Deproteinized Bovine Bone Mineral. A Split-mouth RCT Study With 25 Months Follow-up
研究概览
详细说明
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.

- Current pregnancy or breast feeding/ lactating at the time of recruitment.
- Radiotherapy or Chemotherapy in head and neck area.
- Intravenous and oral bisphosphonate therapy.
- Smoking
- Unwillingness to return for the follow-up examination.
- Conditions or circumstances, in the opinion of the investigator, which could represent a general contra-indication for surgical procedure or would prevent completion of study participation or interfere with analysis of study results, such as history of non-compliance, or unrealistic expectations
- Presence of osseous pathologies, that might interfere with normal wound healing
- Presence of oral lesions (such as ulceration, malignancy)
- Local inflammation, including untreated periodontitis
