What is an internal sinus lift procedure?
Dental implants are a predictable and safe way of replacing lost or damaged teeth. A dental implant needs good quality and adequate amounts of bone in order for osseo integration to occur. In the posterior areas of the upper jaw the bone is usually limited in terms of bone height. In order to place an implant an augmentation procedure may be required. The sinus cavity usually expands when teeth are lost and this expansion continues after tooth loss and reduces available bone even further. In order to place an implant the sinus floor is elevated by means of a sinus lift or sinus floor elevation procedure. Once the sinus floor is elevated a bone substitute is introduced into the sinus cavity. An alternative to sinus floor elevation is using short implants. A short implant is considered if less then 8mm in length. Short implants are available as short as 4mm in length. For more information on short implants see Bicon Dental Implants.
We completed an internal sinus lift procedure today, the technique uses an internal approach to elevating the sinus floor. Gentle water pressure is used to elevate the thin sinus floor membrane. Bioteck biomaterials were used in the procedure. The patient was sedated and the surgery took approximately one hour to complete. A Neodent Alvim 5.0 x 10mm implant was implanted during the surgical procedure. The new bone will take about 9 months to transform into the patients own bone.
