There are 2 types of implants which can be used to stabilise dentures. They normally relate to the lower jaw. However, with the advent of All-On-4 and all the advantages it offers these have become less useful. There main advantage is cost. The main disadvantage is they need ongoing prosthetic maintenance, that mean the parts supporting them wear out and need to be changed every few years.
Mini Implants are an alloy of titanium, vanadium and aluminum. This allows them to be made in small diameters, hence the term mini implants. They were specifically designed to stabilize lower dentures. The procedure is generally a straight-forward one. After a case work up, the implant sites are chosen. The implants are placed and the denture is stabilized on the implants the same day. The existing denture can be used on top. This can be changed into a new denture in a few months if desired. The cost per implant is much lower, hence it is by far a cheaper option. The disadvantage is that the strength is not as great as the conventional implant. The breakage of mini implants is however rare. For a lower jaw 4 mini implants are used. For an upper jaw 6 mini implants can be used to stabilize a denture.
Conventional Root Form Implants
A denture stabilized over the conventional implants is one of the most researched areas of implant dentistry. Hence it is with some confidence that we can state the success rate of this can be high. With at least 2 implants the denture is located onto the implants. Ideally more than 2 implants are used.
The denture can be located with anchors on implants or with clips which hold on to a splinted bar on 2-4 implants.
In summary the uses of implants in dentistry is varied according to the situation at hand. They allow a range of missing teeth iterations to be addressed. The cost of placement also can vary based on the number of teeth or jaws involved. On the patient’s part they require an investment of time and cost and then ongoing maintenance. On the dentist’s part they require planning on where to place and how to restore. It also means keeping up with current research.
