Dr. Vassos conducted a 10 year study on Immediate Loading, the results of which were presented at the Nobel Biocare World conference in Las Vegas, April 2003.

Dr. Vassos has also designed and developed a dental implant positioning system. A must for anyone placing dental implants.

Dr Vassos serves as a clinical advisor to Nobel Biocare , Yorba Linda, California. Along with Dr. A. Buchs of Orlando, Florida and Dr. J. Hahn of Cincinnati, Ohio, Dr. Vassos conducted an extensive five-year clinical implant study for Nobel Biocare. Since 1988,Dr. Vassos and his staff exclusively use the Nobel Biocare implant system, and since 2000 have been placing the Groovy implant which is coated with TiUnite® to the top.
 
TiUnite® has brought a new dimension to implant dentistry since its appearance in 2000.
The properties of TiUnite® allow for intimate interactions between the implant surface and the surrounding living cells and tissues. The enhanced osseointegration and firm anchorage in the surrounding tissues achieved with TiUnite® increases the predictability of implant treatment, especially in clinically demanding situations.
 
Rapid osseointegration.

The surface properties of TiUnite® stimulate bone growth directly on its surface. Bone formation follows the contours of the threads of the implant already during the early phase of healing indicating that TiUnite® is osseoconductive. This results in better maintained initial stability than in implants with a machine surface.
 
Immediate Function™

Maintained stability during the early healing phase, as experienced with TiUnite® implants, is a determining factor for clinical success. Conditions that were previously considered as great challenges can now be treated with high predictability using TiUnite® implants, also when applying immediate leading.
 
Soft Tissue Integration™
 
The soft tissues form a seal around the implant by attachment of the junctional epithelium. The cells of the latter form a firm, direct attachment to the TiUnite® surface via hemi-desmosomes, just as on natural teeth. On natural teeth the junctional epithelium enables by its permeable structure the peripheral immunological defense against microorganisms.
 
Predictable esthetics

Observations from clinical studies indicate that TiUnite® helps maintain the marginal been crest at a very high level and stabilizes the supracrestal soft tissues. Excellent esthetic results have repeatedly been observed with implants featuring TiUnite® at the transmucosal collar.
 

Dr. Vassos also conducted three and six month sinus graft studies with Dr. Peter Petrik, M.D., F.R.C.P.C. and in cooperation with the Division of Oral Pathology, University of Alberta, Edmonton, Canada.

Dr. Vassos is Diplomate of the American Board of Oral Implantology/Implant Dentistry and an Honored Fellow of the American Academy of Implant Dentistry. Dr. Vassos also holds Fellow and Diplomate status of the International Congress of Oral Implantologists. 

Dr. Vassos a general dentist, maintains a private practice exclusively dedicated to dental implants in Edmonton, Alberta, Canada and is the Director of the D.M. Vassos Implant Learning Centre .
