Would you have the tendency to choose a perio dentist who does not refer out for a cbct in prep for dental implants or omfs who has one in office?

It depends: A CT scans will give more information on where to place the implants in those areas where anatomical vital structure may cause complications ( sinus, nerves etc...). In other instances where you can visually or just using a regular X-rays can determine the best position of the implant, it may not be necessary to require a CT. Talk to the treating dentist to understand his choices.

CT standard of care: The CBCT has entered the dental implant realm as the current standard of care with respect to the placement of dental implants. Most general dentists that place implants are getting CT machines in office or are referring their patients to imaging centers. Overall, you want someone that knows how teeth are shaped and where they should be, but you also want a CT scan to be safe.

Easy decision: CBCT and modern materials have made implant dentistry predictable with long-term positive prognoses. Also with CBCT the reconstruction is made simpler and predictable because implants are ideally placed.
