Comparison of open and closed sinus lift procedure before dental implant implantation
Sinus lift is a type of bone grafting before dental implant surgery, during which grafting material is added to the floor of the sinus cavity to increase the height of the maxillary bone at the implant site and prevent the implant from entering the sinus space.. In the rest of this article from Dr. Hossein Borjian's website The best dentist in Isfahan We will compare open and closed sinus lift.
Open sinus lift
Open sinus lift surgery, which is the classic method of this treatment, is the most common type of sinus lift. All this process is done under local anesthesia or anesthesia. After cutting the gum and drilling the implant site, the surgeon carefully pushes up the membrane of the sinus floor with a special surgical tool and adds grafting material to this cavity.. This should be done very carefully so that the membrane is not damaged. After filling the hole, the wound should be closed with stitches.
After the sinus lift surgery, you wait 4 to 6 months for the complete bone tissue to solidify. Then you can place a dental implant. In many cases, open sinus lift surgery is the only method to increase the volume of the maxillary bone.

Complications of open sinus lift
The most important drawback of this method is the high number of injuries and complications. After this surgery, there may be a lot of swelling and bruising under the eyes, chin or neck area. After this surgery, it is necessary to take antibiotics and painkillers for some time.
Suitable conditions for open sinus lift
Open sinus lift is performed for those who do not have enough bone tissue and their jawbone cannot support the implant..
Closed sinus lift
The closed technique in sinus lift causes less damage because there is no need to make a special cut in the gum. In this procedure, all manipulations are done through the hole intended for installing the implant. With the help of special surgical tools, the membrane of the sinus floor is pulled up and an air cushion is created inside it to prevent the membrane from tearing, and then the cavity is filled with bone material..
Closed sinus lift can be performed when the initial volume of the bone is 3 to 4 mm. Then the implant is placed (Immediately after adding Bone grafting). In the closed method, unlike the open method, there is not much bruising and swelling, and the recovery period after the operation is much faster and easier..

Complications of closed sinus lift
The most important thing to consider is choosing a skilled and experienced surgeon to correctly diagnose whether this technique is better for you or a facelift.. Some surgeons are more experienced in closed sinus lift and others in open sinus lift.
So the only drawback to this technique is that it may not be done correctly. Due to the limitation in viewing the structures behind the jaw, the dentist may mistakenly tear the sinus membrane and as a result the whole operation fails and you have to do it again some time later..
Suitable conditions for closed sinus lift operation
Closed sinus lift is performed if the patient has at least 3 to 4 mm of bone. In any case, a complete examination of the mouth and jaw should be done first, and detailed examinations should be done to determine which method is safer and more suitable for you..
