After a tooth extraction, the bone supporting the teeth extracted begin to gradually reduce its volume, a process called resorption. Thus, one year after the extraction was made, the bone is resorbed in average at a rate of 25% of the initial volume. At three years from the extraction, the bone is resorbed at a rate of 40-50%. To prevent bone loss, after extraction stage, sometimes, a bone augmentation (addition of bone) or a dental insertion are required.
Bone addition is the surgery that allows obtaining optimal results in implantology. Thus, after the bone has been added, the amount of available bone increases and an implant with a greater length can be inserted, assuring greater stability. Bone augmentation is a surgery that can be performed simultaneously with the dental implant’s insertion surgery
Another operation in which it is used is the addition of bone sinus lift surgery. As it name indicates, the sinus lift surgery is an intervention that aimes 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 bone addition (bone augmentation) is used if flap surgery when the patient is suffering from periodontal disease, situations in which teeth have lost some supportive bone support. Flap surgery is required when there are deep pockets filled with pus that needs to be cleaned. If the situation allows, bone addition material can be added to support the restoration of the lost bone support. Flap surgery is done also in the periimplantitis case(the infection of the bone around the implant).
The bone addition is also recommended for a surgical procedure called apicoectomy. Apical resection is a surgical procedure in which the granuloma is taken out from the top of a tooth’s root, together with apart of the root tip. It is recommended that in the granuloma’s place, in the bone defect, to add a bone addition material in order to help the bone recover and to prevent recurrences. Apical resection is also a helpful procedure in the cannel treatments that can not be executed correctly. The dental cannels’ retrograde obturation can be done together with the apical resection
