Advantages And Limits Of Dental Implants

A dental implant is a screw that the dentist inserts into the jawbone in order to replace the root of a missing tooth. Different types of materials can be used in the manufacturing process of implants. The commonly used material today is titanium because of its strength, resistance and its excellent level of body tolerance which is known by biocompatibility. Once healed, it serves as an anchor for the tooth to be replaced.

Dental implants can replace one or several missing teeth. They also fix a bridge or stabilize a denture in one completely toothless jaw. During the healing phase, of two months on average, a tight bond between the bone and the implant will be formed. Afterwards a ceramic crown will be fixed on the implant and a full bite force can be applied. With the new advances in implantology, a new approach called "immediate loading" has been developed. It consists on placing the implants and their temporary crowns both on the same day. Even patients with no teeth can benefit from this fast procedure. They will receive up to 8 or 10 dental implants in one appointment, and after 24 hours a temporary prosthesis will be fixed on these implants.

Good oral hygiene and regular checkups by the dentist are essential to maintaining long term healthy implants. Theoretically, in the absence of significant risk factors, dental implants do not have a limited lifespan and are subject to an evolution pattern similar to that of natural teeth. However, from a statistical point of view, around 5% of implants are lost after 10 years which is quite a good performance.
This procedure is available for everyone regardless of adult age. There is no age limit, especially for the elderly people. For anatomical reasons, it is not feasible for patients under 18 years old, in whom the jaw bone growth is not yet complete.

This article will highlight some of the advantages as well as disadvantages and limits of dental implants.

We can note the following advantages:

* Compared to a conventional bridge, the great advantage of implants is that it is not necessary to cut or grind the adjacent teeth.
* In case of complete tooth loss, implants can stabilize the denture or a wide fixed bridge, which has the advantage of improving both the chewing experience and enhance self-confidence.
* The dental implant helps to preserve the bone by slowing bone loss resulting from the extraction of teeth.

Regarding the disadvantages and limits of dental implants, the following can be noted:

* The treatment duration of a dental implant may be longer than the treatment duration of a traditional bridge, especially when preliminary interventions to increase bone mass or improve the quality of the gum are needed.
* Implants require surgery.
* In case of insufficient oral hygiene, implants are more susceptible to periodontitis and other ailments than natural teeth.

The success rate of dental implants varies between 97% and 100%. There is an extremely small risk of implant failure.

Placing an implant in bone with enough height and thickness is quite easy. But be aware that 90% of the cases aren't like this. More often bone graft or gum graft is needed to maintain long term and esthetic result. Please be careful when choosing your dentist. We advise you that a specialist in implantology, such as a periodontist, to place your implants. A periodontist is a specialist in bone and gum surgeries. He is the most qualified to manage implant cases.
