Issue Date: | 2014 | Publisher: | QUINTESSENCE PUBLISHING CO INC | Source: | EUROPEAN JOURNAL OF ORAL IMPLANTOLOGY, 7 (3), p. 283-292 | Abstract: | Purpose: The aim of the present study was to describe nerve fibres around osseointegrated implants in humans. Materials and methods: Twelve mechanically failed implants, retrieved from 10 patients were collected from three dental centres over a period of 5 years. After implant removal, decalcified semi-thin sections (0.5 mu m) were stained with thionic methylene blue for light microscopic analysis. In addition, an ultrastructural analysis was performed on serial ultra-thin sections (0.06 mu m) using transmission electron microscopy. Results: Both myelinated and unmyelinated nerve fibres could be identified inside the Haversian canals of the osteonal bone near the implant threads. Myelinated fibres were also located at the woven bone around the implant. However, no differentiated nerve endings could be observed around the implants. Conclusions: This study shows the presence of nerve fibres in human pen-implant bone. Previous studies in animals showed that those fibres participate in the process of bone modelling and remodelling. Yet, the role of pen-implant bone innervation in the osseoperception phenomenon cannot be ruled out since the mechanism of mechanoreception in bone is not fully understood. | Notes: | [Corpas, Livia dos Santos] Univ Leuven, Dept Oral Hlth Sci, Leuven, Belgium.
