I treatment planned a patient for an All-on-4 and referred the patient to an oral surgeon for placement of the implants. I have not worked with this oral surgeon before. The oral surgeon declined to place the implants and wrote back to me that “without the benefit of a dental laboratory involvement which contradicts multiple years of literature protocol I am declining to take part in the intended surgical treatment plan for this patient”. My question: Is this truly the standard of care? Is it necessary for me to involve the dental laboratory? I have been in practice over 40 years please my own implants and do my own restorations. Your feedback would be appreciated.
