Micromotion is generally described as occurring during the healing phase of an implant. If the micro motion is less than 100 microns the though is that the implant will fuse to the bone (osseointegrate). Once bone healing has been achieved micromotion diminishes. There is always some motion, depends on how close you measure. Microfracture of bone at the implant interface is thought to be what maintains Osseointegration (constant remodeling keeps the implant bone interface vital).
Occlusion sensibility is often described in the 10 micron level. With the movement associated with modeling and remodeling of the micro fractures I would suggest that this would not be at a level high enough for it to be discerned by the patient.
Many thanks for Dr. Narula, Dr. Kanji and Dr. Halkai your nice answers really appreciated, with special thanks must go to Prof. Eckert for his valuable informative answer.
Presence of dehiscence during implant procedure can be successfully treated by GBR procedures. Simultaneous procedure of implant placement and GBR using bone grafts and membranes yield good results. The procedure helps in bone formation and prevents failure of implants and improves the prognosis.
