**A dental implant is only as stable as the bone it’s anchored in — and if that bone has thinned, a bone graft or sinus lift rebuilds it first.** Being told you need one can feel like a setback, but it’s routine groundwork, and skipping it is what actually causes implants to fail. Here’s what each procedure does and why it’s worth the extra step.

## Why bone disappears in the first place

Your jawbone stays strong partly because tooth roots stimulate it every time you chew. When a tooth is lost and not replaced, that stimulation stops and the bone in that spot gradually shrinks — a process called resorption. The longer a gap has been there, the more likely the bone underneath is too thin or too soft to hold an implant on its own. This is one reason replacing a missing tooth sooner is easier than waiting.

## What a bone graft does

A bone graft adds material to a deficient area so your body can build new, solid bone around it over the following months. It’s not the implant — it’s preparing the site so the implant has something to fuse to. Grafts range from small (filling the socket right after an extraction to preserve it) to more involved rebuilding of a long-empty ridge.

We select from proven grafting sources depending on the site — **mineralized and demineralized corticocancellous bone**, and **Platelet-Rich Fibrin (PRF)**, which is prepared from a small sample of your own blood to concentrate your body’s natural growth factors at the site and support healing. Because PRF comes from you, it works alongside your own biology rather than relying only on outside material.

## What a sinus lift does

In the upper back jaw, the sinus cavities sit just above where implants go. When the bone there is naturally thin — or has resorbed — there isn’t enough height to place an implant without entering the sinus. A **sinus lift** gently raises the sinus floor and places bone graft material beneath it, creating the vertical height an implant needs. It sounds dramatic; it’s a well-established, predictable procedure.

## How it fits into the implant timeline

Grafting adds a healing stage. Depending on how much bone needs to build, the implant may be placed at the same time as the graft, or after a few months of healing. Your imaging decides which — 3D scans show exactly how much bone you have and where. The extra months aren’t wasted time; they’re what turns a shaky site into one that will hold an implant for the long term.

## Done under the same sedation

Here’s the part that makes it far less daunting: the grafting and the implant surgery can be done under the [same IV sedation](/implants-under-sedation/), by the same dentist, so you’re not facing a separate frightening appointment for the “foundation” work. Dr. Fatemi handles the graft, the sinus lift, and the implant placement in-office — you rest through it and remember little of it.

## What you can decide now

If you’ve been told you “don’t have enough bone” for an implant, that’s a solvable problem, not a dead end. The next step is imaging to see exactly what’s there and a plan that tells you whether you need a graft, a sinus lift, or neither.
