MISSING FEW TEETH
We refer to the replacement of premolars and molars in the upper and lower jaw in the back of the mouth.
Missing back teeth greatly impairs your chewing efficiency. Using your front teeth to chew food eventually causes arthritic changes in TM Joint which leads to facial pain and headaches. People who are very thin will also have sunken cheeks giving them an old age look. Most often patients neglect this area as this is not cosmetically visible in your smile. Many years of toothless condition leads to severe shrinking of jaw bones in that region. This makes the placement of implants very demanding and additional surgical procedures may be needed to augment the shrunken bone.
Posterior teeth replaced will be limited till the second molars. Third molars or wisdom tooth is not replaced by dental implants. It is generally considered the first molars give 90% biting efficiency. Second molars give 7% biting efficiency. Third molars have less than 3% biting efficiency.
Placing dental implants in the back of the mouth is technically more demanding as the vital structures like nerves and sinuses are present in this region.
A detailed x-ray examination will give an indication about the available bone in the jaw for placement of implants. On examination if the bone volume is less then bone augmentation procedures are needed to place the implants. This can be done safely by trained maxillofacial surgeons. So if you have been told that there is insufficient bone by any implant dentist, your next step will be to meet a maxillofacial surgeon trained in implant dentistry.
It is also noticed that some implant dentists who are not trained in placing implants in compromised jaw bone in the back of the mouth removes good front teeth to place implants so that the back teeth can be cantilevered from the front implants which is not a good practice.
