How Older Implant Crowns Were Redesigned for a Better Bite and More Natural Appearance

Older implant crowns redesigned with full upper reconstruction

Redesigning older implant crowns in Washington, DC. This documented case at Elite Prosthetic Dentistry rebuilt an upper arch where aging implant-supported crowns, placed in a compromised position more than two decades earlier, no longer supported a stable bite or natural appearance. Treatment was planned and completed by Dr. Gerald Marlin, D.M.D., M.S.D., a prosthodontist focused on implant reconstruction and complex restorative care.

The presenting condition

The patient came in after years of living with implant crowns that did not feel right cosmetically or functionally. A comprehensive evaluation including a CBCT scan, reviewed with a radiologist colleague, revealed that her existing implants were not positioned or supported well enough to deliver a stable, healthy, esthetic long-term result. Her upper and lower front teeth were not meeting properly, and that missing anterior contact was contributing to moderate-to-severe TMJ symptoms.

Why this case required prosthodontic-level planning

Older implant crowns are rarely a simple replace-in-place situation. When the underlying implants were placed under outdated planning, lower-density bone, or compromised positioning, swapping out the crown alone produces a result that looks better for a season and then fails on the same compromised foundation. The real question in this case was not which crowns to use. It was what to do about implants that had been placed in the wrong position, in bone too thin to rely on, and that were standing in the way of a healthy bite.

The decision behind the result: what to do about the existing implants

The most important judgment in this case was what to do about the patient’s existing implants. They had been placed years earlier too far toward the cheek side, the buccal, because that was the angle of the available bone rather than the position the final teeth actually needed. The abutments and crowns built on them had been set too far out to compensate, which looked and functioned poorly and left the upper and lower front teeth without proper contact.

A CBCT scan, reviewed with a radiologist colleague, showed the implants were embedded in very thin bone. Two responses would have been conventional here: restore the implants as they sat, or remove them. Neither was right. Restoring them would have locked in the same compromised position that caused the problem. Removing them would have created two unsightly bone defects in the exact area being rebuilt for appearance.

The decision was to leave the implants undisturbed in the bone and to deliberately not restore them. That choice opened the space to position the new upper front teeth where they belonged, so they could finally meet the lower teeth properly. Restoring that anterior contact mattered for more than appearance. Its absence had been contributing to the patient’s moderate-to-severe TMJ symptoms. This is the kind of decision that separates replacing parts from planning an outcome, and it is why a case like this belongs with a prosthodontist.

The treatment plan

The outcome

The result was a stable, natural-looking upper reconstruction. The front teeth now meet properly, the anterior open bite is corrected, and restoring that contact addressed a key contributor to the patient’s TMJ symptoms. It is a coordinated long-term result built on a sound foundation rather than another short-term refresh of compromised work.

Who this case may sound familiar to

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

• Your implant crowns are 15 to 25 years old and have started to look or feel different from the rest of your mouth.
• Your bite no longer comes together correctly and the older implant work is part of why.
• You have been told the implants may not be ideally supported and you want a real evaluation before deciding what to do.
• You want one coordinated plan to rebuild the upper arch correctly rather than a patchwork of repairs.
• You need treatment delivered under sedation because of dental anxiety.

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

Frequently asked questions

Can older implant crowns be redesigned without removing the implants?

In many cases yes. When the underlying implants are positioned and supported well enough, the visible crown can be redesigned while preserving the existing implant. A prosthodontic evaluation including CBCT imaging confirms whether the implant is suitable to carry a redesigned restoration.

What happens if the existing implants cannot support a new restoration?

They do not always have to be removed. When implants are poorly positioned but well integrated in the bone, taking them out can create defects that are harder to repair than the original problem. In some cases the better decision is to leave them undisturbed, not restore them, and rebuild the bite and the teeth around them. A prosthodontist makes that judgment case by case after reviewing the bone and the planned final result.

How do you know if a 20-year-old implant crown should be replaced?

Signs include changes in fit or feel, esthetic mismatch with the rest of the mouth, bite changes, recession around the crown, or a CBCT showing bone loss or compromised support around the implant.

Why see a prosthodontist for older implant crown redesign?

A prosthodontist evaluates the implant, the bite, and the surrounding dentition as a connected system. That coordinated planning is what allows the redesigned restorations to fit a corrected bite rather than the bite that allowed the original problem to develop.

Is sedation an option for patients with dental anxiety?

Yes. Treatment is routinely delivered under IV sedation when appropriate, allowing longer, more complex appointments to be completed comfortably.

What role does an in-house laboratory play in this kind of case?

An in-house laboratory provides direct, immediate control over fit, contour, shade, and translucency. That level of coordination is difficult to achieve when laboratory work is outsourced.
