What is the goal of a sinus bone graft in dental procedures?

The primary goal of a sinus bone graft in dental procedures is to obtain adequate vertical height of bone. This procedure is commonly used in situations where the maxillary sinus has pneumonated or when there is insufficient bone due to tooth loss or resorption in the upper jaw. By performing a sinus lift and augmenting the bone in this area, dental professionals can create an environment that supports the placement of endosteal implants.

When there isn’t enough bone height, placing an implant can be challenging or impossible. The sinus grafting procedure allows for the addition of bone material, which ultimately increases the vertical height of the bone in the maxillary region, providing a stable foundation for future implants.

While ensuring long-term success for implants is a consideration in many dental procedures, particularly regarding the health and quality of the bone, it is the attainment of sufficient bone height that specifically addresses the biomechanical requirements needed for implant placement in the sinus area. This focus on bone height directly impacts the predictability and stability of implant integration.

Increasing the number of endosteal implants may be a consequence of successful sinus grafting, but it is not the primary objective of the procedure. Reducing sinus height for easier access is contrary to the goal of bone augmentation, which aims to
