Fig 1:  This is the traditional approach to implant supported prosthesis in the upper jaw.  It dictates that the implants be placed vertically into the jaw supporting the dental prosthesis from one end to the other.

Observe that:

In this example, there is enough bone to place implants at the ends of the prosthesis.  However, these implants at the back are in the softest bone of the jaws, where implants are less stable than implants at the front of the jaws where the bone is harder.

Implants are placed vertically, and this is the dogma of traditional implant placement.

The two ends of the implants are not engaged into the cortical bone layers of the jaw (the lower dark line) and the sinus floors (the upper dark lines).  This is another dogma and protocol of traditional implant placement.

Typically, dentists who use this approach would recommend 6 to 12 implants to support the prosthesis.

Figure 2:  In this situation the sinuses are larger and are where the back implants need to be (Figure 3).  Your surgeon may angle the implants into the side walls of the sinuses (Figure 4), placing bone into the sinuses by internal sinus lifting (Figure 5), or doing open sinus bone grafting to allow the implants to be fully surrounded by bone (Figure 7).

Figure 3:  This is an inside view of the jaw and sinus.  The top portion of the back implant is into the sinus without bone support.  This view is only possible if the surgeon has a CT scan of your jaw.

Figure 4:  The implant is angled into the inside sinus wall.  This requires the surgeon to be very experienced and use a CT scan or being CT guided during the surgery.

Figure 5:  Bone graft material is pushed into the sinus when the hole was made to place the implant.  This method of placing bone into the sinus is called internal sinus lift.

Figure 6:  In this situation, the sinus is so large that the dental implant would have most of it into the sinus and not supported by bone.  A lateal sinus bone grafting procedure would have to be done as a separate surgery to eventually allow implants to be placed (Figure 7).

Figure 7.  The sinuses are so large as to require large amount of sinus bone grafting.

An implant supported bridge does not do as well when the back teeth are not placed over a dental implant but extending past the last dental implant (cantilever).

Another way to say it, the implant supported bridge does better if the ends of the bridge are supported by the last dental implants on both sides.

Traditionally, this is done by placing bone graft materials into the sinuses and waiting for them to heal and turn into patient's own bone for 6 months, and then dental implants are placed.

In this approach, more surgical procedures, higher rate of risks, higher cost, and prolonged healing time are needed compared to the All-On-4(tm) approach.

With the traditional approach, 6 to 12 implants are often placed into the upper jaw to support a full prosthesis.
