Can I wait for 9 months to put a crown on my implant? (Photo)

Hi:You can delay the implant crown however you are risking the movement of the new root canal and crown tooth super erupting again.  You may want to consider a night guard or clear retainers to keep the tooth in its place until next January.Best,Dr. Maddahi

You can wait but risk the problem of supra-erruption happening again. Just because your insurance won't cover the cost doesn't mean that you can't get the crown, you will simply need to pay out of pocket. 

The first thing to consider in this plan is do you even need to have the molar replaced. One option could be to just remove the upper molar as many people can function fine with only one set of molars. If you decide to go ahead with the implant it does look like the upper molar has drifted down and will need to be reduced to make room for the implant crown which is why you have been advised on the RCT and crown. Waiting to restore the implant is usually fine as the typically heal in the bone from 3-6 months although 9 months may be a little long. Research shows that most teeth start to move when unopposed after about 6 months. In your case if you go ahead with the RCT/Crown the tooth could drift down again while waiting on the implant crown. The risk of that is probably pretty low as teeth move slowly but something you should still consider.
