These positions look okay to me–but i might suggest some slight modification. So, because this is a partial, the implants don’t necessarily need to follow the angulation of the teeth.

Instead, the things to try to optimize for aside from bone availability are:

1. Parallelism between the fixtures. It would be great to try to get them somewhat parallel. Doesn’t need to be perfect, but close to parallel.

2. Parallel to biting force. Biting forces will happen in a vertical dimension, so it would be great if the implants were also close to vertical–along the same axis as the biting force to avoid shear stresses on them.

That said, you don’t want those anterior implants to come out too far on the palate because you’ll run out of restorative space. It’s a balance.

One solution for the anterior might be to use some angled locators on those. They fix that up real quick.

2mm subcrestal would be good. Hardest thing on this case will be making sure you have enough restorative space so your partial doesn’t break.
