Their bone generally lacks sufficient density and thus the implant cannot fuse correctly with the bone. However, new research is promising to increase the overall success rate of the dental implants.
A few researchers from the Universitat Jaume from Castellon in Spain have developed a new, special implant coating material which will help patients with low bone density get dental implants. Moreover, since the coating is highly biocompatible, the treatment time of the dental implants procedure will be significantly reduced. The surgical area will heal better, and osseointegration will happen much faster.
Up until now, the titanium part of the implant which was supposed to replace the root of the tooth, took about 2 to 3 months in order to fuse nicely with the jawbone. Thanks to the innovative implant coating, patients will be able to have their dental crown (the visible part of the tooth) fitted much sooner. This will automatically reduce the overall treatment time, increase the success rate and thus patients can be back to their normal life sooner too.
How the special implant coating works
According to Julio Jose Suay who is the main coordinator of the Polymers and Advanced Materials research group of the University, the dental implants will be covered with a layer of this special coating. The coating is biodegradable, which means that slowly it will dissolve.
During the dissolving process (or degradation process), the coating releases special silicone compounds and important bioactive molecules. As these molecules and compounds are released they will induce the bone generation process. Thus, patients with a low jaw bone density will go through a bone regeneration process after the dental implant is inserted.
Dental implant integration with the bone is the most important process of a dental implant procedure. If there is not enough bone density, the titanium part will not fuse correctly with the bone and the entire treatment can fail easily. Of course, patients with severe bone density loss are generally going through grafting, but this is a very lengthy and painful process.
This new biodegradable coating material that helps inducing bone generation in the dental implants treatments is an extremely competitive project in the research field. The researchers already managed to go through the testing phase with cell cultures, and they also tested it on live animals. Now, researchers are awaiting the clinical evaluation phase, and according to estimates in about 2 to 3 years the special bone generation coating can already be marketed and used in the dental offices worldwide.
People with jawbone deficiencies are always the most vulnerable when it comes to treatments such as dental implants. When there is not enough jaw bone density, the implants are impossible to fit. However, replacing missing teeth is very important, because if they are not replaced correctly, the bone will deteriorate even more and everything can lead to gingivitis and periodontal disease or even serious TMJ disorders.
