Patient question

I have several damaged teeth in my upper jaw and would like to replace them with a fixed, implant-supported solution.

For my lower jaw, I would prefer to preserve my natural teeth if possible and restore the missing or damaged areas with dental implants and zirconia crowns.

Would it be possible to have All-on-4 treatment in my upper jaw while keeping my remaining lower teeth?

Based on the initial assessment, a combination of All-on-4 implant treatment for the upper jaw and zirconia restorations for the lower jaw may be considered.

The aim is to replace the teeth with a poor prognosis in the upper jaw while preserving your natural lower teeth, provided they are healthy and stable.

Proposed Treatment Plan

1. Upper Jaw – All-on-4 Implant Treatment

For the upper jaw, the proposed treatment includes:

  • Full extraction of the remaining upper teeth

  • All-on-4 implant treatment, using four strategically positioned dental implants

  • A fixed implant-supported hybrid prosthesis to restore the upper jaw

This approach is designed to replace the remaining upper teeth with a fixed restoration supported by dental implants, improving chewing function, comfort, and smile aesthetics.

2. Lower Jaw – Dental Implants and Zirconia Crowns

If your remaining lower teeth are stable and show no significant mobility, they may be preserved and included in the restorative treatment plan.

The proposed treatment includes:

  • 2 dental implants in the regions of teeth 44 and 46

  • 12 zirconia restorations covering teeth 36–31 and 41–46

This option aims to restore the missing teeth while improving the shape, colour, symmetry, and overall appearance of the lower teeth.

3. Additional Dental Treatments

The plan may also include:

  • Professional dental cleaning to maintain healthy teeth and gums

  • A custom night guard to help protect the final restorations from excessive bite forces, clenching, or grinding during sleep

Important Considerations

The stability of your remaining lower teeth is particularly important when deciding whether they can be preserved.

If the clinical examination reveals significant tooth mobility, advanced bone loss, or periodontal problems, the lower jaw treatment plan may need to be reconsidered.

The final treatment plan will be confirmed after a detailed intraoral examination, assessment of tooth mobility and gum health, and three-dimensional CBCT evaluation.

Our priority is to provide a stable, functional, and natural-looking smile while preserving your healthy natural teeth whenever possible.
