What are dental implants ?
Dental implants are medical-surgical devices that allow the insertion of an artificial tooth to the jaw or jaw of the subject through a support for the attachment to the bone. Dental implants are divided into subperiosteal ( obsolete, and consist of an external support attached to the bone with screws that held the tooth in position) and endosseous , fixed within the bone , by means of a screw or of a blade metal .
The metal used is generally titanium, because of its high hardness and rust resistance , often alloy of vanadium to improve the tensilità . The titanium blends with the surrounding bone tissue due to a phenomenon called " osseointegration ." The screws have function of support for other types of prosthetic dental implants , such as crowns , dentures and bridges .
Before the intervention of surgery plant , making a radiographic evaluation of the framework will be engaged where the screw to prevent the detachment of the prosthesis due to its own weight if the bone does not prove strong enough .
The intervention includes a first surgical incision , followed by the drilling of the bone with peaks of progressively larger caliber , to drill a hole where it will be subsequently implanted with the self-tapping screw . To avoid cell damage due to high temperature , the area is constantly cooled by a continuous jet of saline.
The times of recovery following the intervention are approximately 3-5 months , which allow bone to grow around the screw , which is then welding it on site. To this is then applied to the denture itself, at a distance of about 1-3 months after the first operation , or in some cases immediately , at the same time the intervention of the removal of the original tooth .
The dental prosthesis is therefore composed of a metallic abutment that is fixed to the screw , and a ceramic crown applied on this , manufactured tailored on a cast of the original tooth . If the system spans multiple adjacent teeth , you speak instead of dental bridge .
