^sorry to hear about this. This either falls under "not enough time to do it right the first time, but plenty of time to do it over again." OR "timing is everything- telling the patient beforehand an explanation, telling the patient after the fact is an excuse."

Couple of thoughts:

Really engage the general dds/ oral surgeon on how to make it better. Communication between the 3 parties (you- the dds and the os) is critical now.
General DDS can make templates to guide the oral surgeon. Depending on the extent of tx, guides might not make a difference or even be necessary, but in some cases they can make all the difference.
Sometimes the oral surgeon cannot use the templates/ do what the general DDS wants due to bone limitations.
Short implants might be necessary due to anatomical constraints- for example, an implant placed in the lower back of the mandible might need to be short not to damage the nerve that provides sensation to the lower lip/chin..so a short implant is placed, but it might not be a favorable leverage ratio to actually support what the general dds planned..
Perhaps it's an upper implant and really needs a sinus fill to get a decent implant length.

At any rate, engage them both at this point and you might get a much better end result than anybody imagined- for example- an extra implant to make up for the lack of space/ shallow implant on the bottom, or some sinus lift for the lack of space on the top. It's too hard to make conclusions over the internet, but there is an opportunity here for a good end result.

Engage them both positively to see what happens.
Good luck!
