Maxilla implant placement in Class 3 Occlusion?

I have a patient who presented with missing maxillary anterior teeth #7,8,9 and 10. She currently wears a removable partial. She is in a Class III occlusion. The overjet of her lower incisors extends approximately 6mm labial to the maxillary crestal ridge. If I were to place implants at sites 7 and 10 with fixed 4 unit bridge(7,8,9,10), the custom abutment would need to be at least 45 degree labially. I think it will look very odd, not to mention the cantilever force it will create. So my question is, how many of you would refer to an oral surgeon for block graft. I have been placing implants for 5 years but this case I’m thinking of referring out. By the way, the patient is of Asian ancestry. What do you recommend?
