Simcha asks:
I am caught up in differences of opinion from several dentists that I consulted regarding implants. Two of them are quite famous for implant work. Those two also had different answers regarding having a snap in denture.
Everyone agrees that there is not enough bone in the sinus area. One opinion states that a bar supported by four implants will be fine without sinus lift. Another says that a mini sinus lift will do it and another says that a full sinus lift is a must. I hear that the bar without a sinus lift is likely to fail after five years. How am i suppose to make a choice? Of course i would love to skip a sinus lift. The more I research the more ideas I hear. Can someone give me advice in this matter. I would appreciate it very much...thanks

Hi Simcha:
You have asked some very important questions, which I will try to answer as best I can.
It is not unusual to have consultations which vary greatly, and I know that it is difficult to decipher the information, as it can be confusing. After all you are not a dentist.
However, consider the biomechanics or physics of having a denture supported by dental implants. If the implants are spaced out nicely, they will help to distribute forces very well, and the denture will be more stable, and function well. If the implants are only placed in the anterior segment of the upper jaw, there is a potential that when you bite into something with your front teeth, the denture could "tip" up in the front, and dislodge from the back end. Therefore, if you can have implants placed in the posterior or back part of the upper jaw, it might help to balance your bite. If you do not have enough bone in the back portion, you may then require the sinus lift procedure as you described.
You need to discuss these options with these dentists and first determine the quality and quantity of bone which will help to anchor the implants, where they will be placed, and how they will support the denture against your lower teeth. A CT or CBCT scan might be appropriate to help in the diagnosis of the available bone. If everything is designed properly, you should have many, many years of service from the implant supported restoration.
