How do you get optimal long-term treatment outcomes for your patients? The standard norm (1-3) regarding dental implant treatment success from 1986 does not reflect what is possible to achieve today. There are no reasons why the clinician or the patient should accept a marginal bone loss of up to 1.5 millimeters based on a standard set 25 years ago.
How did we come to the conclusion that the ASTRA TECH Implant System™ has an average marginal bone level reduction of less than 0.3 millimeters after the first year of loading and that it remains stable after five years?
A total of 32 scientific articles reporting average changes in marginal bone levels with ASTRA TECH Implant System were found, according to a literature search of publications in English peer reviewed scientific journals, January 2011. Inclusion criteria for the 32 studies were:
When the ASTRA TECH Implant System data was presented to Tomas Albrektsson, Professor of Biomaterial Research at the Sahlgrenska Academy, University of Gothenburg, Sweden, one of the authors of articles from 1986 and 1993, he said in a press release*:
“The limited marginal bone resorption being documented on ASTRA TECH Implant System indicates that it is time to reconsider our old ‘standard’ from 1986. The new standard should perhaps only allow 50% or less of the bone resorption currently accepted as a successful result.”
It is certainly time to set a new standard.
