Grafting an Upper Molar Socket?
Dr. N. asks:
A question came up at our dental implants study club recently and I thought I would post it to get others opinions. The question was: when is it best and when it not best to graft an upper molar socket that you know will require an antral wall sinus lift augmentation later in order to place a dental implant?
Some thought it best to be done immediately after extraction to help maintain crestal width regardless of later needing to gain vertical height. Some felt it best not to graft in order to let the peaks and valleys of the root outline inside the sinus reabsorb away to allow for easier separation of the sinus membrane later when the sinus graft was being done — thus only grafting one time. A few felt it only prudent to graft after extraction if you knew in advance that you could later do a simple crestal sinus lift through the crestal bone when the osteotomy was done thus avoiding the more involved lateral wall sinus augmentation.
What are your thoughts and why? Thanks for any opinions.
