Implant-supported prostheses (fixed over implants)
The preconditions, especially the quantity and quality of the bone, as well as the proximity of important anatomical structures that could be damaged by the placement of the implants, decisively limit the possibility of recovering function and aesthetics in an absolute way.
The lack of bone can force to place the artificial teeth away from the gum, forcing even to reproduce an artificial gum that, for reasons of hygiene, should be separated from the true gum, leaving visible the metal columns that are anchored to the implants ( hybrid prostheses). In these cases, the lips usually cover these misadjustments, thus maintaining a normal aesthetic appearance.
It is very important that our patients trust us with their aesthetic expectations in order to assess whether it will be possible to satisfy them completely.
The bone loss (resorption) that occurs after the loss of the natural tooth is not recovered when placing the implants and the implant-supported fixed prosthesis; the loss of support that is sometimes seen in the upper lip due to bone loss will not be completely resolved in this way.
Limitations of the implant-supported prosthesis
- The implant-supported prosthesis is a treatment that, in order to recover the function and aesthetics of missing teeth as much as possible, consists of a structure that is fixed to the implants (previously placed inside the maxillary bones), by means of the use of cements or screws.
Adaptation and adjustment to the implant-supported prosthesis
- When the prosthesis is placed on the implants for the first time, it is usual to notice a variable intensity pressure that ends spontaneously remitting.
- At first you may notice a feeling of occupation or foreign body, which usually disappears in a few weeks, getting used to it.
- It increases the production of saliva, although it gradually normalizes.
- It changes the speech a little, being able to exist phonetic problems to pronounce some sounds, reason why habitually a training is needed to learn to vocalize certain words, what usually is obtained in few weeks. Reading aloud in front of a mirror helps to recover, in a short time, a clear and fluid speech.
- It is very likely that they bite easily cheeks and tongue, for their tendency to enter the spaces where teeth are missing, but in a short time you learn to avoid it.
- Small changes in facial appearance and expression are often noticed; in a few weeks it is normal to get used to the new appearance.
