Dental implants and implant-supported restorations require great knowledge and experience. . The rehabilitation plan is conducted with the accompaniment and consultation of a prosthodontist.
The implant inserted into the bone is just an anchoring point, and now comes the stage for which the implant was inserted, which is completing the missing tooth. The restoration is done using a crown. There are two options, a cemented crown and a screw-retained crown. In the case of a cemented crown, we connect an abutment to the implant, the abutment protrudes above the gums, and we bond the crown to it. In effect, the restoration consists of three units – the implant in the bone, the abutment screwed onto it and a crown bonded to the abutment. A screwed-on crown is a crown that is screwed directly onto the implant without an abutment. The restoring dentist makes the choice according to the clinical situation. In the same manner, multiple implants may serve as a brace of a bridge, which will either be on abutments or screwed directly to the implants. In any case it is a fixed restoration.
In the case of completely edentulous jaw, multiple implants (denture anchoring points) are to be placed, depending on the chosen denture type.
A fixed denture requires installation of six to eight implants in the jaw. Here two options are also possible – a screw-retained denture and a cemented one. In the case of a screw-retained denture, a bridge of porcelain crowns will be screwed directly onto the anchoring implants. In the case of a denture bonded to the implants, abutments will be screwed into the implants and a porcelain bridge bonded to the abutments. Another option is a specific case, All-on-4-6 (link to all on 4-6).
Advantage: the end-result is as close to natural teeth as possible.
This is a denture that rehabilitates the entire edentulous jaw and allows for restoration of its basic functions, such as speaking, eating, supporting the lips and cheeks and more. The denture rests only on the gums and jawbone in the lower jaw, so after a few years of use it loses its stability. In the upper jaw it is seated on the gums and palate, and therefore, it interferes with speech, is very uncomfortable and greatly impairs the sense of taste.
To overcome these disorders, it is recommended to use 2-4 implants in the lower jaw and 4 implants in the upper jaw, with a bar connecting them. This forms an anchor on which the denture may rest – providing stability, confidence, and much better and more effective eating and chewing. Also, an upper denture consisting of 4 implants does not interfere with the palate, and is thus more convenient and has a much shorter adjustment time.
