Both Arches Rebuilt After Advanced Periodontal Disease: Twelve Guided Implants and a Signature Hybrid Prosthesis

Both arches rebuilt on implants after advanced periodontal disease

Full-arch implant reconstruction of both arches in Washington, DC for a patient whose remaining teeth had been lost to advanced periodontal disease. This documented case at Elite Prosthetic Dentistry sequenced extractions, bone grafting, sinus lifts, and osseodensification before six guided implants were placed in each arch and restored with a Signature hybrid prosthesis. Treatment was planned and completed by Gerald Marlin, D.M.D., M.S.D., a prosthodontist who plans the surgical and restorative phases of full-arch cases together within one specialist practice.

The presenting condition

By the time this patient came to the practice, periodontal disease had progressed well beyond what cleaning and gum treatment could reverse. The bone that holds teeth in place had been lost around the upper and lower teeth, the teeth were loose and failing, and traditional restorative options such as crowns or bridges had nothing stable left to attach to. He wanted a result that would hold up, and he wanted to understand each step before committing to it.

Why the foundation had to be rebuilt before any teeth were made

A full-arch implant case after periodontal disease is not a tooth-replacement problem first; it is a bone problem first. Implants need bone of adequate height, width, and density to integrate and to carry chewing forces for decades. When the disease has taken that bone, placing implants into what remains invites the same instability the patient is trying to leave behind. The sequence matters: remove the sources of infection, rebuild the ridge and the sinus floor where bone is short, improve the density of the bone that will hold the implants, and only then place implants in positions chosen for the final prosthesis rather than for whatever bone happens to be available. A prosthodontist plans the final prosthesis first and works backward to the surgery that will support it, so the surgical sequence, the periodontal foundation, the prosthetic design, and the comfort plan are engineered together before treatment begins.

The treatment plan

After a comprehensive evaluation and digital imaging, the reconstruction was organized as a phased sequence with the final prosthesis design driving every surgical decision.

The outcome

The completed reconstruction gave the patient two stable, implant-supported arches in place of teeth that could no longer be kept. The before and after views at the top of this page show the change from loose, failing teeth to a complete, even smile. At every stage the team walked him through what was being done and why, and the final result restored not only his ability to chew comfortably but his confidence to smile again.

Who this case may sound familiar to

This story tends to resonate with patients in a few recognizable situations:

• You have been told your remaining teeth cannot be saved because of gum disease and you want to understand what a planned, permanent solution looks like.
• You have lost bone and have been told implants are not possible without rebuilding it first.
• You want a fixed, implant-supported result rather than a removable denture, and you want to know the options at different levels of investment.
• You want one practice to plan and carry out the surgery and the final teeth rather than coordinating between offices.
• You want the foundation done correctly so the result is still stable many years from now.

If any of those describe where you are, a consultation with Dr. Marlin can give you the diagnostic picture and the specific plan for your case.

Frequently asked questions

Can dental implants be placed after advanced periodontal disease?

Yes, once the disease is controlled and the bone has been rebuilt where it is deficient. Periodontal disease destroys the bone implants depend on, so most of these cases begin with extractions, bone grafting, and sometimes sinus lifts before implants are placed. The timing and sequence are planned from imaging so that the implants end up in positions that support the final prosthesis properly.

Why place six implants in each arch instead of four?

Both configurations can succeed. Six implants per arch spread chewing forces across more support, give the prosthodontist more flexibility in prosthesis design, and provide a margin of safety if one implant were ever to have a problem. The number is chosen case by case from the available bone, the patient’s bite forces, and the prosthesis planned for the arch.

What is a hybrid prosthesis?

A hybrid prosthesis is a full-arch bridge that is fixed to the implants rather than removable by the patient. It replaces the teeth and the lost gum and bone contour in one piece. Hybrids can be made with different tooth materials and frameworks; the practice offers several designs so the choice can be matched to the patient’s function, esthetics, and investment priorities.

What is osseodensification and why was it used here?

Osseodensification is a way of preparing an implant site that compacts and expands the surrounding bone instead of removing it. In a jaw weakened by periodontal disease, it improves the density of the bone around each implant and can widen a narrow ridge, which helps the implant achieve stable integration.

More about the work behind this case

This case combines full-arch dental implants with bone grafting and sinus augmentation to rebuild what periodontal disease removed. The sequencing reflects the practice’s philosophy on complex reconstruction, and the prosthesis was built with the in-house laboratory.

Elite Prosthetic Dentistry treats patients from across the DMV including Bethesda, Chevy Chase, McLean, Arlington, Potomac, and Great Falls, and from much further out for cases that warrant the trip.
