Penetrating the Maxillary Sinus

Last Updated: Dec 25, 2006

Dr. Chin asks:

I recently placed 4 dental implants in the maxillary jaw. The panoramic
radiographs I took before the procedure showed a 13mm vertical bone
height in the left premolar area. I was planning to place 11.5mm length
implants there.

The panoramic radiographs I took after the procedure show that 1 dental implant I placed penetrated the maxillary sinus by about 3mm. Primary stability is very good for all 4 dental implants. Will I have to trephine out the dental implant and replace it with a shorter implant? Or can I leave them all as is and have a delayed loading? I am planning to restore the case with an overdenture. How long should I wait to load the dental implants?
