What is the purpose of using mini-pins during sinus elevation procedures?

The purpose of using mini-pins during sinus elevation procedures primarily aligns with the goal of avoiding the sinus membrane. Mini-pins are typically utilized to provide anchorage and support while elevating the sinus membrane safely and effectively. Their small size allows for precise placement, minimizing trauma to the surrounding tissue, including the sinus membrane itself.

By strategically positioning these pins, the clinician can create a stable environment for the subsequent placement of graft material and avoid perforating the delicate sinus lining. This is crucial, as a perforation in the membrane can lead to complications such as infection or graft failure, reducing the success of the sinus lift procedure. Thus, the use of mini-pins is instrumental in ensuring that the integrity of the sinus membrane is maintained while elevating it to augment the bone volume necessary for implant placement.
