Sinuses are literally cavities in bones in the face area, and the size of the maxillary sinus is often a limiting factor for dental implants, especially in the upper jaw.
The maxillary sinus may be so large that only a few millimetres of bone in the upper jaw remain. This is especially the case in the molar area, to which it’s most important to place the implants to enable proper chewing system function.
Sinus lifting is the procedure of raising the bottom of the maxillary sinus to create a sufficient amount of bone for implant placement in the upper jaw, in the area of the molars. This surgical procedure is performed so that the sinus is reached laterally, above the gums, then the sinus membrane is lifted and an artificial bone substitute is placed between the jaw and the sinus membrane.
If the bone augmentation is less extensive, we can instantly place the dental implant during the sinus lifting. If the bone augmentation is more extensive, we wait for 4 to 6 months for the bone to coalesce and then place the implant.
The procedure is completely painless and is done with the use of local anaesthesia.
