sinus Lift
What is a Sinus Lift?
Los senos maxilares están detrás de las mejillas y encima de los dientes superiores.. Estos senos paranasales están vacíos., espacios llenos de aire. Algunas de las raíces de los dientes superiores naturales se extienden hasta los senos maxilares.. When these upper teeth are removed there is often just a thin wall of bone separating the maxillary sinus and the mouth. Dental implants need bone to hold them in place. Cuando la pared del seno es muy delgada, it is impossible to place dental implants in this bone.
La clave para un implante dental exitoso y duradero es la calidad y la cantidad de hueso maxilar al que se adherirá el implante.. If bone loss has occurred due to injury or periodontal disease, a sinus augmentation can raise the sinus floor and allow for new bone formation. A sinus lift is one of the most common bone grafting procedures for patients with bone loss in the upper jaw. The procedure seeks to grow bone in the floor of the maxillary sinus above the bony ridge of the gum line that anchors the teeth in the upper jaw. This enables dental implants to be placed and secured in the new bone growth.
Am I a Candidate for a Sinus Lift Procedure?
A sinus lift may be necessary if you:
- are missing more than one tooth in the back of your jaw
- are missing a significant amount of bone in the back of your jaw
- are missing teeth due to a birth defect or condition
- are missing most of the maxillary teeth and require support for dental implants
How is this procedure Accomplished?
Más comúnmente, se hace una pequeña incisión en la región premolar o molar para exponer el hueso de la mandíbula. Se corta una pequeña abertura en el hueso., y la membrana que recubre el seno es empujada hacia arriba. El espacio subyacente se rellena con material de injerto óseo., either from your own body or from a other sources. A veces, synthetic materials that imitate bone formation are used. After the bone is implanted, the incision is sutured and the healing process begins. After several months of healing, the bone becomes part of the patient’s jaw and dental implants can be inserted and stabilized in the newly formed sinus bone.
If enough bone between the upper jaw ridge and the bottom of the sinus is available to sufficiently stabilize the implant, los aumentos de seno y la colocación de implantes a veces se pueden realizar como un solo procedimiento. Si no hay suficiente hueso disponible, el aumento de seno se tendrá que realizar primero, then the graft will have to mature for up to several months, dependiendo del tipo de material de injerto utilizado. Una vez que el injerto ha madurado, the implants can be placed.
The sinus graft makes it possible for many patients to have dental implants that previously had no other option besides wearing loose dentures.
A sinus augmentation is generally performed at Dr.. Abt‘s office, under local anesthesia. Some patients may request oral or intravenous sedative medication as well.
