Question:
Sinus Lift caused by jawbone deterioration? I have 2 missing upper right molars.
I'd like to get implants. The dentist that did the last extraction said that I need a bone graft for the first extracted tooth which was extracted less than a year ago. He said my sinus needs to be pushed up before the implant can be placed there.
Can there be that much bone loss that quickly? He also said that if I only get one implant and then get a bridge again that the one implant will move. Is that true? ....Visitor from PA
Answer:
Without seeing you or viewing x-rays of your extracted area, it's hard to give you a conclusive diagnosis.
However, if the last dentist said you may need a slight sinus lift before an implant could be placed he may be correct. If the tooth has been out only a year, your need to have the sinus lifted is not due to bone resorption or bone loss.
The maxillary nasal sinus is located above your upper back molar teeth. In some people the sinus hangs
way down, almost to the point of touching the roots of the top molar teeth. In these patients a bad sinus
infection puts pressure on the roots and nerves of the top teeth, and causes root canal type pain symptoms.
So if your sinus is low, there may not be enough solid bone for the length of the implant that is needed. To gain the needed thickness of bone for your implant, a dental instrument called an ostiotome is used to push or move bone up into the sinus a bit to make room for an implant.
This procedure is usually done by a Periodontist (Gum Specialist), who could also place the titanium dental implant. Once an implant is in place and has fused with the bone (osseointegration), it will not move.
