Which treatment is NOT considered an option for Division B to allow for standard root form implant placement?

The most accurate choice for a treatment that is not considered an option for Division B to facilitate standard root form implant placement is osteogenic distraction. This technique involves a surgical procedure to gradually separate bone segments to allow new bone formation in the space created. It is typically used in cases where significant vertical bone enhancement is necessary and is not standardly employed as a strategy during implant placement in Division B.

In contrast, treatments like osteoplasty, bone manipulation, and onlay bone grafting are aimed at preparing the existing bone architecture for standard root form implants. Osteoplasty allows for the reshaping and smoothing of the ridge, while bone manipulation or spreading can help in widening the ridge to create adequate space for implant placement. Onlay bone grafting is also a common method that involves adding bone to the ridge to enhance its volume and promote successful integration of the implant. These options are frequently utilized when dealing with insufficient bone for conventional implant techniques, making them preferred choices in Division B scenarios.
