Horizontal GBR in the posterior mandible, using the L-prf bone block protocol
Dr. Stefan Matthijs, Periodontist
Belgium
Patient: 57-year-old female, no systemic diseases, no oral pathologies
Clinical situation: Tooth 46 (FDI) was removed 8 months earlier. Missing lower molars 46 and 47. Reduced masticatory function. Horizontal bone deficiency and reduced soft tissue volume.
Surgical planning: Horizontal bone regeneration, prior to implant placement.
A mixture of small and large size Nobel Biocare creos™ xenogain granules and L-prf was used to create a soft bone block. The bone substitute was covered by a Nobel Biocare creos™ xenoprotect resorbable membrane and L-prf membranes. No pins were used to stabilize the membrane. The need for soft tissue augmentation was evaluated at a later timepoint.
Prosthetic planning:
Individual screw retained crowns on implants
Chronology of the treatments:
27th of April 2017: Guided bone regeneration
10th of November 2017: Implant placement
25th of January 2018: Evaluation of the integration – start of the prosthetic treatment
9th of August 2018: First clinical and radiological evaluation of the final reconstruction
24th of October 2022: Clinical and radiological evaluation during the yearly supportive implant care visit.
Total treatment time:
10 months - 5-year follow-up
