Are Sinus Problems a Possibility After Having Dental Implants Installed?

The risk to the sinus during dental implant surgery is low. More often then not, one to two millimetres of an implant can penetrate the sinus cavity during placement of the implant without any untoward effects or long term compications. If there is ever any concern that there is not enough bone under the sinus, a procedure called a "sinus lift" protocol is performed. This allows the surgeon to place more bone into the sinus air cavity thereby providing more bone to stabilize the implant(s). 

There is very less chance that you will have a sinus problems after having the dental implants installed. But, in some cases, people who have lost a tooth on the upper row of teeth and, also are considering dental implants might have lost an amount of bone. 
Without enough bone, it is possible for an implant to stick up into the maxillary sinus, increasing the risk for infection and discomfort.There are various reasons why person might not have sufficient bone for a dental implant. Advanced cases of a periodontal disease not only affect the good gums and teeth health, but it has capability to damage the bone as well. Another reason for a lack of bone in the  upper part of the jaw has to do with how long a person’s been missing his or her teeth. The bone supports the teeth, and without a tooth in place, it is likely that the body will reabsorb the bone, since it’s no longer doing anything.

Upper posterior teeth approximate the maxillary sinus very often.  When the teeth are lost the sinuses sometimes enlarge (pneumotize) and/or the bone where the teeth used to be resorbs which in turn then leaves only a thin layer of bone beween the oth and the sinus.  If implants are to be placed in theses areas a sinus lift bone graft needs to be performed to make sure there is enough bone to secure a dental implant.  This involves manipulating the linig of the sinus and packing bone beneath it.  This willl prevent the dental implant from sicking up into the sinus .  A sinus infection is a rare occurance with this procedure, but it does happen .  If a dental implant is placed in the area without adequate bone and the implant is "sicking up" inside the air cavity of the sinus, a sinus infection may develop, but even on these cases it is rare,  The take home message is: sinus infections can occur, but they are rare.  IF they deelop they are easily resolved with proper treatment and care.
