Would doing implant on teeth 12 & 13 require for a sinus lift or touch sinus floor. 12 &13 missing & under bridge for 15 y. is bone graft is needed?

Possibly: Only your dentist, who has your x- rays, can determine this. However based on the length of time these teeth have been lost, probably a sinus lift and bone graft will be needed. There should be bone between the implant and sinus floor.

See Prosthodontist: You need to see a prosthodontist and oral surgeon to diagnose your situation. All depends on where and how much bone you have in those areas. Often it is possible to this without affecting sinus. If under bridge for that long, there is a good chance that the sinus has pneumatized downward and reduced the bone in these areas. Need imaging to evaluate. Good luck.

11 mm bone height: A minimal of 11mm bone height would be preferred for the implant of 11mm to be placed in the area. 11 mm is the minimal length that would ensure 99% success rate in implant therapy.

Possibly: If there is not enough bone below the sinus in this area in your particular case, this may be a necessity. In some individuals the siuns done not come that far forward especially in the #12 are. Every case is different.

Probably: If the teeth have been missing for that long, most likely a bone graft will be needed to rebuild the bone volume of the jaw in that area so the dental implants can be stable. A cat scan should be taken of the jaw to determine the amount of bone present.

Depends: When teeth have been missing for a period of time the sinus will begin to drop. There is a certain minimum height and width of dental implant that is needed to replace these teeth so that a long term successful prognosis can be achieved.. If you do not have this height and width then you may need to consider bone grafting.

Need a CT scan: Without a ct scan it is not possible to determine if you require a bone graft for certain, however, it would not be surprising if you need sinus augmentation. I think it is wonderful that you are considering dental implants...Be certain you are working with dental specialists like prosthodontist and periodontist to ensure you have the best treatment outcome possible.

Xrays can determine: Sometimes the dental xray or panorex xray is inadequate to determine whether a sinus lift is necessary. In cases where the surgeon is unsure he/she may recommend a dental catscan that gives the 3 dimensional analysis as to whether there is adequate bone to house a dental implant (and whether a sinus lift and/or bone graft is necessary.

Get an Scan: Most of the time the sinus is not afected in surgical implants in 12 and 13 site. In order to be sure you need a cat scan. But bone grafting is very common necesary due to bone loss.

Depends on anatomy: Each individual has different anatomy and so every case is unique. The x-ray attached is of an individual who's sinus floor was high enough so no additional procedures were needed! even if in your case a sinus lift or bone graft is required, in the right hands, these are highly predictable and very successful procedures. Only a comprehensive exam and imagining study will dictate what is best 4 u.

Possibly: A 3d image would be needed to determine the bone height available to place the proper size implants. After this, the surgeon may be able to place the implants with only a tiny amount of bone at the time of implant placement, he may require a larger graft prior to placing the implants, or it may be possible to place the implants without needing any type of bone graft. Have the 3d image first.
