Implant Brands To Choose

To summarize the most important design elements, titanium grade, screw thread design, roughened surface, choice of length, several diameters, indexing,  replaceable abutment screw, titanium and zirconia stock abutments can lead to a more predictable and long lasting final restoration. Reflecting on these outlined implant design considerations it is now possible to divide implant systems in to four distinct groups. "Class A" implant systems have all the above mentioned 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. The following chart is by no means all inclusive of all available implant manufacturers but includes the market leaders at this point in time. Others will be added as this site grows.

To further expand on available and nice to have but not necessary features we can add local (within one hour driving distance) manufacturers sales reps. These representatives can be a great resource on technical issues and be physically in your office to lend you a hand familiarizing yourself with their implant system. This is a great value since the rep can show you the ins and outs of what and how to do, when and where, essentially accelerating your learning curve significantly.
A feature that can save you a significant amount of money and cut down on the multitude of parts needed is a fixture mount or implant carrier that comes pre attached to the implant body that can also be used as an impression coping and final abutment. The surgeon can forward this multi use coping to you. Torque requirements for the final abutment vary from manufacturer to manufacturer. The range goes from 15Ncm to about 35Ncm depending on manufacturer. Science dictates that a higher torque will hold the final abutment more securely in place. To maximize the versatility and esthetics of zirconia abutments the connecting part of the abutment should have no metal reinforcement, either bonded or press fit to the abutment. A through and through zirconia abutment is therefore more desirable.
Taking these expanded features ( Multi use coping, Torque equal or greater than 20Ncm, through and through zirconia abutment) in to account, the classification of some implants will change considerably. The only variable that is not taken in to account in the expanded classification system is the availability of a local manufacturers account representative. If you practice in a metropolitan area or close to one the chance of having access to a live person are much greater then if you were practicing in a more rural setting. Although a rural setting does not necessarily preclude you from this great service, sometimes the size of the implant manufacturer is so big they can afford to maintain a tight network of sales reps, at other times you might just luck out.
