Abstract
|
|
|
To determine the effects of magnetic fields by comparing interaction between the osteoblast and titanium dental implant with a magnet which is inserted in the specially designed implant abutment. Dental implants connected with a magnet - inserted abutment were used. A cell-spreading assay in which percentages of cells at four different stages of attachment were identified by scanning electron microscopy and quantified within 30 min. 4hour and 24hour attachment periods. The surfaces of dental implant connected with a MagScrew showed significantly enhanced rates of cell spreading in comparison with the others. Based on these observations. it appears reasonable to suggest that magnetic fields promote the differentiation and maturation of osteoblasts by affecting the expression of adhesion proteins imbedded in the cell membrane and may have a favorable effect on immediateloading implant treatment by reducing the processing time for
mineralization.
