All-on-4 is a full-arch restoration technique. Rather than replacing each missing tooth with its own implant, four implants are placed in the jawbone at precise angles to support a fixed set of prosthetic teeth. The result is a complete arch that looks, functions, and feels like natural teeth without the need for removable dentures.
The two rear implants are placed at an angle (typically 45 degrees), which allows them to engage more bone than vertically placed implants. This makes All-on-4 a viable option even for patients who have experienced some bone loss.
All-on-4 is typically recommended for patients who:
- Are missing most or all teeth in one or both arches
- Have been told they do not have enough bone for traditional implants
- Are currently wearing full removable dentures and want a permanent alternative
- Want a more stable, fixed solution than what denture adhesives and removable plates can provide
Patients with uncontrolled diabetes, active gum disease, or significant bone loss may need additional treatment before proceeding. At CharlottePerio, we evaluate every patient individually. If bone grafting or periodontal therapy is needed first, we handle that within our practice before moving forward with implant placement.
Your first appointment includes a thorough evaluation of your bone structure, gum health, and medical history with one of our board-certified periodontists. We use advanced imaging to plan implant placement precisely, accounting for bone density and sinus anatomy.
On the day of surgery, any remaining failing teeth are extracted (if needed), and the four implants are placed. For eligible patients, a provisional fixed arch is attached the same day.
The implants integrate with your jawbone over the next four to six months. During this time, the provisional arch allows function while healing occurs.
Once healing is confirmed, your restorative dentist works in coordination with CharlottePerio to place your permanent prosthetic arch. This final restoration is crafted to fit precisely and match your natural bite.

Removable dentures do not stimulate the jawbone. Without stimulation, bone continues to deteriorate, altering facial structure over time and causing a sunken appearance that prematurely ages many denture wearers. All-on-4 implants preserve bone by functioning like natural tooth roots
