Description of the procedure
The All-on-4 treatment concept provides a permanent, screw-retained, same-day replacement for the entire upper and / or lower set of teeth. The procedure is best for patients with significant tooth loss or decay and for people whose bone loss in the jaw area prevents them from getting dental implants. Often, tooth loss is accompanied by loss of the jaw bone which poses the problem of reconstruction of the jaw bone. For the implementation to be successful it is necessary to transplant bone from other parts of the body, for example, the iliac crest or the skull and apply it in the area where it is planned to deploy tooth or teeth. Transplantation of bone graft technique takes between three and six months so that the implants can be placed. After implant placement, it is necessary to wait two to three months, after which time it is possible the placement of the fixed prosthesis.
The All-on-4 treatment concept owes its name to the very nature of the method, which consists of applying a dental prosthesis with at least twelve teeth (bridge) fixed in the jaw, based only on four titanium implants.
The specific implants or pillars used by Malo are protected by international patenting.
Patent claims for the dental implant fixation
According to the first claim accepted under the European patenting process, the implant is characterized by having a form that allows an effective anchoring even in a jaw bone with a combination of soft and hard bone portions or inlays, which fixture can be applied in holes with diameters which are substantially smaller than a main diameter of the fixture so as to produce a clamping effect on the fixture from the soft bone portion or portions, said fixture comprising an outer surface, the main diameter, an end surface and a front portion, which from the point of view of diameter grows very much narrower towards the end surface and which is arranged with both a cutting function and a threading function and is thus able, upon contact with a hard bone portion or portions, to penetrate through these hard bone portions without causing any substantial tendency for displacement of the respective hard bone portion, and a thread which has one, two or more thread turns and extends along the greater part of the outer surface and also down along the front portion while substantially maintaining its thread profile, wherein the main diameter is 4 mm, the diameter of the end surface is 2 mm, and the front portion has a Height which is substantially equal to the diameter of the end surface.
