A sinus lift is only added when your scan actually shows you need it
This isn't a treatment anyone chooses upfront — it's added to an implant plan only when a 3D scan shows there isn't enough bone height in the upper back jaw to place an implant safely without it.
What a standard sinus lift typically costs
A sinus lift, when needed, commonly adds somewhere in the range of roughly €350–450 to an implant treatment plan, depending on the technique used and how much bone augmentation is required.
Why some cases need it and others genuinely don't
After a tooth has been missing for a while in the upper back jaw, the sinus cavity can gradually expand into the space where the tooth root used to be, reducing available bone height. Whether this has happened to a meaningful degree is only visible on a 3D scan — not something you can tell from how your mouth feels.
The "closed" vs. "open" sinus lift distinction
A closed sinus lift is a smaller, less invasive technique used when only a small amount of extra height is needed, often done at the same time as implant placement. An open sinus lift is a separate, larger procedure used when significantly more bone volume is needed, usually requiring healing time before implants are placed.
Why this affects your treatment timeline, not just the price
If an open sinus lift is needed, it typically adds several months to your overall treatment timeline, since the grafted area needs to heal and integrate before implants can be placed on top of it. This is worth planning around if you're coordinating international travel.
The honest bottom line
You won't know whether you need a sinus lift, or which type, until your case is actually reviewed with a 3D scan. Be cautious of any quote for upper back implants that doesn't mention this possibility at all.
