Missing Transmucosal Healing Cap: How Temporarily Seal?

In most cases you should be able to get a healing cap overnighted by the company. In that short time, I would not worry. Just irrigate the open implant, put a little antibiotic ointment on the threads of the new healing cap and place. My suggestion would be to have a at least two caps for each size in your inventory. You never know when you will need them :)

Why don't you use coverscrew,if you have saved it.

if you don't have a cover screw, put cotton pellet then temp filling material at the top

This is a great solution. Use a light body PVS impression syringe with a fine intra oral tip and extrude the material into the screw hole until flush with the surrounding tissue. I have a photograph of where I have done just that and the tissue tolerated nicely. This saves this expense, inconvenience, and pain of placing an healing abutment after the tissue has moved.

Two days after bilateral maxillary sinus graft, patient presents with blurred vision in left eye in the morning which becomes normal in 4-8 hours. This recovery period has shortened and is 3-4 hours now ten days post surgery. Any comments/opinions/feedback/advise will be appreciated.

One quick solution is to use gutta percha. You can just take a medium size gutta percha point, heat it slightly and insert into the implant. Then compress the end so that it also acts to keep the tissue from collapsing around the implant. When the gutta percha cools, it should end up just above the tissue height. It will be stable enough to stay in place, but not so difficult to remove in one piece when yu are ready for the next procedure. Try it.

i will put a coton pellet inside the implant and cover it with a surgical dressing like coe pack or similartill it flush with the surrounding tissue.In all cases it's a provisional solution till you get the definitive one...In my humble opinion if it's a matter of one or 2 days i won't do anything just irrigate and let the patient do some mouth wash and that's it...

Probably a secondary effect of the corticoids
