The success of a dental implant and its ability to support a dental restoration is very much dependent upon how much bone is available in the site where the implant is placed.
There are lots of factors that affect the bone volume including periodontal diseases, trauma and infections.It is not unusual to open up a site in the mouth for implant placement and find that some of the critical supporting bone is missing. Replacing missing bone or adding to the existing bone is very often essential to the success of a dental implant and the ensuing restoration (supporting crowns).
We at GUMS N SMILES have the latest, state of art techniques available to replace missing bone.Using these techniques we can increase the height of bone, the width of bone and fill in all sorts of defects that develop when teeth are lost.
SINUS LIFT is one of the procedures used to increase the availability of bone for doing maxillary (upper jaw) implants. Sinus lift or sinus augmentation is an implantologist or a periodontist executed procedure, to increase the amount of bone in the molar area of the upper arch in order to prepare it for the insertion of one or more dental implants. Sometimes the sinuses are enlarged and intrude on the areas where we want to place dental implants
….It can also happen because of resorption of the bone caused due to tooth extraction.
….If the back teeth in the jaw are not replaced in time after extractions, sinuses tend to enlarge, thereby resorbing available bone for the placement of implants at a later stage.
A dental implant cannot be placed in such areas as there would be no bone holding it in place.This is when doing a sinus lift gets important. It could be done in a conservative manner (indirect sinus lift) or an elaborate surgery (direct sinus lift), depending upon the increase in the height or the width of bone that is required.
A thorough evaluation is done by the implantologists at GUMS N SMILES before proceeding with any form of treatment.This includes XRAYS to study the anatomy of your jaws and sinuses. A CT (computed tomography) SCAN is also advised to accurately measure the height and width of your existing bone and evaluate the health of your sinuses.
In order to carryout a sinus lift, there can be the use of either bone tissue originating from the patients body (autogenous bone) or that of synthetic nature (allogenous bone.. bone in a bottle) which is more commonly used and can also stimulate the formation of new bone material.
So for doing a Direct lift, we merely open up the side of the sinus and raise the bottom portion of the sinus. The area is then grafted with bone and tissues are stiched shut. We can then go back, 4-6 months later and place an dental implant in solid bone.
A conservative way would be what is calledIndirect Sinus Lift. This procedure or the osteotome lift is done without actually opening the sinus. The sinus is gently elevated through the site where the implant is to be placed. Healing and implant integration then proceed in a normal manner.
The doctors at GUMS N SMILES after a thorough evaluation would be able to guide you for the treatment plan and procedure required.
