There are many different brands of dental implants, making it very hard to choose which one is good for your needs. The situation is not made any simpler by the fact that each dental implant brand has many different types, different sorts of implants, designed to give certain benefits, or to be strong in a certain field of dental implantology.
But how does a customer know which one to buy if they do not happen to be a dental implantologist? In this article I will not be looking at the different implants themselves as a comparison, but instead I intend to look at certain features of dental implants, to give the reader some information to look for in any dental implant given.
One of the most obvious differences between dental implants that is apparent at first sight is the way that they are shaped. Most dental implants look like tiny screws with hollow heads. But then some of them are arrow shaped, and some of them are longer or shorter than others.
The reason for the arrow shaped implants is because certain people do not enough bone material to handle the threading of regular dental implants, but do not wish to, or simply cannot have a bone regenerative surgery, due to health reasons, or financial situation. The arrow shaped dental implant is much thinner, and thus requires less bone material to stabilize it, but can handle just as much occlusal force (the pressure exerted during biting and chewing) as any other dental implant can.
The other very obvious difference is that certain dental implants come with a tapered end, almost as if it had fins, or wings. These wings are basically an extra wide threading system, and these dental implants lock into the jaw in much the same way that a screw does. These kind of dental implants are referred to as instant, or immediate load dental implants. These dental implants can only be used by patients who have very strong jaw bones, and as their name implies, they do not require a healing time, but can be used for biting and chewing immediately after the anaesthetic wears off.
A key difference to note that may not be very obvious at a glance is the diameter of the dental implant. As dental implants are basically artificial tooth roots, it should be of no surprise that they come in different diameters to replace any given tooth, as teeth come in many different sizes, and so do their roots. Smaller diameters are usually reserved for front teeth, while molars require larger diameters, or sometimes, they may even require two dental implants next to each other.
Dental implant surfaces are where the majority of new testing and development takes place. Different surfaces will take longer or shorter amounts of time to integrate into the jawbone, and ti is now stipulated that porous surfaces are the best kind of dental implant surface, as the bone material is able to grow around and into the surface of the dental implant, thus providing greater stability and quicker integration times. They do carry the risk of becoming infected, as bacteria can also live in porous surfaces.
With this information, it should be a little bit easier to discern between the different kinds of dental implants, and what they do. I will be revisiting this topic in further articles, to clarify some more what sort of dental implants can be used for what purposes.
