If you are missing most or all of your teeth or struggling with dentures that do not stay in place, All-on-4 dental implants offer a permanent, fixed solution. At Osler Dental Professionals in Towson, MD, we use computer-guided technology and precision surgical techniques to provide you with a full set of teeth securely anchored in your jaw.
All-on-4 dental implants are a full-arch tooth replacement system. Four titanium implants are placed in your jawbone at strategic angles, and a complete prosthetic arch of teeth is fixed directly onto those four anchors.
The result is a permanent, stable set of teeth that functions like your natural smile. You eat, speak, brush, and floss with them the same way you would with natural teeth. Unlike traditional dentures, All-on-4 implants do not rest on your gums, slip when you chew, or require adhesive creams.
You are likely a strong candidate for All-on-4 dental implants if one or more of the following apply to you:
The best way to confirm your candidacy is to come in for a consultation. Dr. Constantine and Dr. Libby will perform 3D imaging, review your dental and medical history, and explain exactly what your treatment would involve.
All-on-4 dental implants address the core problems that come with tooth loss and removable dentures. Here is what you gain with this treatment:
Your All-on-4 journey follows a clear, structured path from your first visit to your final smile.

Your first visit begins in one of our comfortable consultation rooms, not the dental chair. Dr. Constantine or Dr. Libby takes time to understand your goals and dental history. We use digital X-rays and 3D cone-beam imaging to assess your bone and plan your treatment.

Using your 3D scans, we create a detailed surgical plan with computer guidance. Our Digital Smile Design technology lets you preview your new smile before any treatment begins. This service is available at no cost to you.

Four implants are placed in your jaw using our computer-guided technique and 3D surgical guides. Any failing teeth are extracted at this same appointment if needed. In most cases, a temporary fixed arch of teeth is attached the same day, so you leave our Towson, MD office with a complete smile.

Over several months, your implants fuse with your jawbone in a process called osseointegration. We use platelet-rich fibrin (PRF) to support faster tissue regeneration using your body's own concentrated healing factors. A soft-food diet is followed during this healing phase.

Once your implants are fully integrated, your permanent prosthetic arch is attached. We take digital impressions and 3D print the models in-house to ensure a precise, high-quality fit. Your final teeth are shaped and shaded to complement your face naturally.

Your All-on-4 implants require regular professional cleanings and check-ups. Our team walks you through the specific home care technique for implant-supported prostheses to ensure your results are healthy and lasting.

Not in most cases. The angled placement of All-on-4 implants takes advantage of denser areas of bone, which eliminates the need for bone grafting for many patients. Whether you need a graft is determined after your 3D imaging and exam.
Coverage varies by plan. Some plans cover a portion of the implant procedure or the prosthetic teeth. We accept all major insurance plans. Our team reviews your coverage with you during your consultation and explains all available payment and financing options before you commit to treatment.
All-on-4 uses four implants to support a full arch, while All-on-6 uses six. The two additional implants in All-on-6 distribute load more broadly and are suited to patients with more available bone. All-on-4 is often the preferred choice for patients with some bone loss because the angled design works effectively with fewer implants.
