Evaluation of the Effect of Platelet Rich Fibrin Membrane on the Neurosensory Function Following Inferior Alveolar Nerve Lateralization for Implant Placement

Abstract

Aim: The aim of this study was to evaluate the effect of PRF membrane on the neurosensory disturbance of
the inferior alveolar nerve following IAN lateralization surgery for immediate implant placement.
Methodology: The study was conducted on six patients underwent IAN lateralization surgery for immediate
implant placement and the nerve was surrounded by PRF membrane. The neurosensory disturbance was
evaluated using visual analogue scale preoperatively and postoperative at 1 week, 2 weeks,1 month,3 month
and 6 month.
Results: At 1 week post-operative 100% of the patients had recorded complete absence of sensations in the
lip and chin region. At 6 month post-operative (66.6%) of the patients has recorded score 4 and (33.3 %) of
the patients have recorded score 5.
The mean and median value significantly decreased at one week post-operatively, then gradually increased in
the subsequent observations. Friedman test revealed a significant difference between observations (p=0.00).
Conclusions: The PRF membrane resulted in no immediate postoperative improvement of the neurosensory
disturbance of the inferior alveolar nerve following IAN lateralization surgery for immediate implant
placement and the nerve recovery followed the normal course.
