It is important to bear in mind that depending on the existing conditions (such as the amount and quality of your bone, and adjacent anatomical structures that could be damaged by the implants) it is not always possible to achieve this 100%.
A lack of bone sometimes means it is necessary to position the teeth above the gum, creating a type of artificial gum that, for hygiene reasons, must be separated from the real gum using
metallic abutments anchored to the implants (hybrid dentures). In these cases, although the lips cover the dentures and the appearance is normal, inside the mouth the dentures are visible.
It is very important that you tell your dentist what you expect from your prosthesis, in order to evaluate whether these expectations can be met in full.
It is also important to note that the loss of bone (reabsorption) that occurs after losing your own tooth will not be recovered on fitting implants and the fixed implant-supported prosthesis. The indentations sometimes seen in the upper lip, area of the canine teeth or other areas due to bone loss cannot be completely resolved in this way.
