Reflecting on the outlined implant
design considerations it is now possible to divide implant systems in to
four distinct groups. "Class A" implant systems have all of the nine
crucial
attributes. A "Class B" system has all but one of the design features. "Class C"
systems have two elements missing and "Class D" three or more aspects amiss
(Brand comparison chart).
The following classification is by no means all inclusive of all available implant systems but includes the market leaders at this point in time. Others will be added as
they become more relevant.
* Implant brands within class D systems are ordered from highest point value to lowest point value.
Additional desirable implant features are discussed in the supplementary
expanded design considerations.
