The maxillary sinuses are air filled spaces in the cheek region.  The bone between the roots of the upper posterior teeth and the maxillary sinuses is often very thin.  After extractions the jawbone resorbs.  As this occurs the sinus cavity is closer to the jawbone ridge.  This often results in inadequate bone in which to place implants.

Sinus lift procedure can overcome this.  A bone graft is placed under the sinus membrane resulting in the sinus cavity being raised up.  Over several months the bone graft integrates with your own jaw bone. This results in enough bone being present in which to place an implant.

We use bovine bone and porcine collagen during the sinus lift procedure.

44 year old male seeks replacement of upper right 1st premolar tooth space.

Alveolar height, from the crest of bone to the sinus floor is demonstrated on OPG & cross-sectional CT as being only 7.9mm deep… too shallow for a conventional implant to be placed.

Pre-emptive bone-graft surgery to the sinus floor allows for bone depth to increase to 16.4mm, with graft consolidation occurring over 4 months.

Implant placement to the site, now accommodates a narrow platform 13mm length collared implant, & which is now entirely embedded & osseo-integrated with grafted, living bone. X-ray shows relationship of implant to grafted bone, & supporting the final dental-crown.
