One of the most common reasons patients delay exploring full-arch implant options is concern about bone grafting. They’ve been told by another provider they don’t have enough bone, or they’ve been quoted for a graft as a prerequisite. The design of All-On-4® dental implants is specifically built to work around that limitation in most cases.
Why All-On-4 Usually Skips the Graft
Standard single-tooth implants are placed vertically and require sufficient bone height and density directly at the extraction site. When a tooth has been missing for years, that bone has often resorbed and the site no longer meets those requirements. That’s the scenario where grafting becomes necessary for traditional implant placements.
All-On-4 takes a different approach. The four posts are placed in areas of the jaw where bone density remains reliably higher, particularly toward the front. The posterior implants are angled, which lets Dr. Porter anchor the arch in stable bone even when the sites directly under where back teeth used to be have insufficient volume. That angled placement is what allows the procedure to succeed without grafting in a large percentage of patients.
How Dr. Porter Evaluates Your Bone
Every All-On-4 evaluation at Charlotte Dental Arts includes a CBCT scan, which produces a three-dimensional image of the jawbone. Dr. Porter uses this imaging to measure bone density and volume at specific regions before planning placement. Patients don’t go into surgery hoping placement will work — the map is laid out in advance, and post placement is virtual before it’s surgical.
The scan also identifies anatomical structures that affect where posts can be placed safely. Nerve canals and sinus position are both visible on CBCT and both factor into the surgical guide.
When Grafting Is Still Part of the Plan
All-On-4 doesn’t eliminate the need for grafting in every case. Patients with very advanced bone loss across all jaw regions may not have enough stable bone for even angled placement. When we see that, we discuss the options honestly, including whether a phased approach with bone regeneration makes sense before implant surgery.
If a graft is what gets a patient to a successful long-term result, Dr. Porter recommends it directly and explains why. If it can be avoided without compromising the outcome, it will be.
