In some cases when we want to replace a tooth in the upper jaw with an implant, we cannot do it because we do not have enough bone to hold the implant.
The tooth loss has resulted in bone loss and lowering of the sinus. In these cases we need to lift the sinus and augment the bone before implantation. Sinus lift is usually conducted immediately before implantation in the same visit, if there is at least some bone volume.
In other cases, sinus lift is done during a separate visit and 6 months need to pass before implantation. Sinus lift is a completely painless procedure as it is done under local anaesthesia.
It is normal for this procedure to be done at the same time as implantation, if there is at least some bone volume.
If there is no bone at all 6 months need to pass between sinus lift and implantation. Sinus lift is done under local anaesthesia so the procedure is completely painless.
This term is used for the whole set of procedures that are undertakenin order to increase the bone volume so that the the dental implant could be inserted. All procedures, generally, include addition of bone material. It can be an autologous bone (bone transplant taken from other location in the patient’s mouth) or an artificial bone.
The procedure for replacing the lost bone is known as Guided Bone Regeneration (GBR).
If you are already missing a toothand there is not enough bone for implantation,
the missing bone needs to be replaced in order to create a good base for implantation. After this procedure, it is necessary to wait for four to six months in order for bone to completely appear before implantation.
If the implant is inserted into the upper jawbone (maxilla), the bottom of the maxillary sinus is usually set low. In this case, the sinus lift is performed.
Alveolectomy is surgical removal of impacted and retained wisdom teeth. Certain teeth can be prevented frommoving but that does not mean that tooth development is stopped. Impacted and retained teeth are teeth which have not been completely formed within the bone but have also not sprouted in their place or at any other spot within or outside the dental arch.
The reason for this can be the unfavourable direction of sprouting or insufficient amount of space in the dental arch for sprouting due to other teeth or othermechanical obstacles (bone or soft tissue).
In this case, impacted and retained wisdom teeth can cause symptoms like pain and swelling, which is why alveolectomy is prescribed. Impacted or retained teeth are discovered through an X-ray image or are established through a clinical examination with the presence of pain, swelling or other forms of discomfort.
Apicotomy is an oral surgical procedure through which a portion of a tooth’s root (apex) is removed,usually due to chronic pain or fracture in the area of the root (granuloma or cysts). Apicotomy is conducted under local anaesthesia, which means the procedure is painless. The procedure starts with incision of gums and lifting of gums in order to reach the root.
The procedure is used to remove a part of the root along with the inflammatory process, after which the root canalis filled with various specialized materials and compounds. Depending on the individual state of the patient, the tooth can be endodontically treated (through cleaning and widening of the canal and its filling) before or during the procedure itself. The incised portion of the gingiva is finally put back into its place and the wound is stitched back up.
Apicotomy is an increasinglycommon procedure as it allows the patients to preserve the teeth which could not be treated through endodontic treatment and which would otherwise had to be taken out. It is considered a minor surgical procedure and it lasts from 30 to 60 minutes, depending on the region and the tooth.
The procedures on front teeth are generally shorter,while those performed on lower molars are usually the longest.
