When molars and premolars are extracted, the upper jaw undergoes bone loss that can worsen over time. In addition, the occurrence of infections also causes bone loss.
In this oral region is the maxillary sinus, which is a membrane-covered air hole that usually increases in size over the years after the removal of molars and premolars. When there is little amount (height) of bone to place dental implants, dental experts have the possibility to perform a sinus lift. This makes it possible to regenerate the lost bone and have enough bone available.
What does a sinus lift surgery consist of?
The technique consists in the elevation of the sinus membrane and, subsequently, the placement of a graft, which will maintain the space to achieve the regenerated space. It is an intervention that is performed under local anesthesia and on an outpatient basis, so it has minimal complications.
When is maxillary sinus lift performed?
If the patient has a minimum amount of bone, the technique will be performed the same day the implant is placed. However, if the bone loss is advanced, a first phase of sinus lift should be performed and, after six months, the implants should be placed.
How to know if it is feasible to undergo a sinus lift
Maxillary sinus lift is still a surgical technique, so a correct diagnosis and planning by means of a CAT scan is necessary to verify that there are no contraindications for its execution. Also to locate the presence or not of polyps or thickening of the sinus membrane, which would impede proper execution.
Results of the maxillary sinus lift technique
Maxillary sinus lift is a common technique with a high success rate if the established protocol is followed. It is an effective solution for edentulous patients with little maxillary bone.
