Wisdom teeth often do not resemble in morphology with the other teeth and are very difficult to treat, thus often extracted. To remove them, often small surgery are needed.
Wisdom teeth are removed only when they cause different problems (crowding front teeth, pain at the eruption’s site) or caries appear and can not be treated anymore. For the impacted and semi-impacted wisdom teeth a surgery in a sterile field is done, under cooling with dental saline or through piezosurgery.
There are cases where dental implants can not be inserted until the sinus lift surgery is performed.
As it name indicates, the sinus lift surgery is an intervention that aims to raise the membrane of the maxillary sinus in order to add an amount of bone quantity, that is required for the implant insertion, because the implant is inserted into the bone .
The maxillary sinus is a cavity located in the upper jaw, is filled with air and communicates with the nasal cavity and the other sinuses.
The cause leading to sinus lift surgery is represented by dental extractions performed in the past, once a tooth being extracted, the bone holding it starts to be absorbed. Therefore, 3 years from the extraction, bone is reabsorbed in 60%, making impossible the implant insertion without the bone addition, or more precisely the sinus lift surgery.
The apical resection is a surgical procedure in which the granuloma is taken out from the top of a tooth root together with some of the root tip. It is advisable that instead of granuloma in the bone defect to put a material addition to help the bone to recover and to prevent recurrences.
Apical resection is a helpful procedure as well for canal treatment that were not executed correctly. A retrograde root canals obturation with apical resection can be done.
