Implant-Supported Malo Bridge with Individual Ceramic Crowns

They refer to different aspects of treatment.

All-on-4 describes a treatment concept in which four implants support a fixed full-arch prosthesis. Malo Bridge describes the structure of the definitive prosthesis fitted over the implants.

A Malo Bridge can be used in All-on-4 cases, as well as All-on-5, All-on-6, or other full-arch restorations supported by multiple implants, depending on the treatment plan. While All-on-4 typically uses four implants, All-on-X protocols may involve additional implants based on available bone, arch length, occlusal load, and the selected restorative materials.

Malo Bridges and monolithic zirconia bridges differ significantly in structural design and clinical application. In terms of structure and materials, a Malo Bridge combines a metal framework, individual all-ceramic crowns, and prosthetic gingiva. A monolithic zirconia bridge, by contrast, has its teeth and main body milled as a single structure, primarily from zirconia.

These structural differences affect maintenance and adjustment. Individually fabricated crowns on a Malo Bridge can allow localized repair or replacement if damage occurs, depending on the design. Each crown can also be individually contoured to refine its esthetics. A monolithic zirconia bridge is generally more challenging to repair locally, and its esthetic appearance relies mainly on the overall design and surface staining.

Weight also varies with the design and materials. A Malo Bridge may be lighter, depending on its framework and crown materials, while a monolithic zirconia bridge can be relatively heavier.

With an individual crown design, a damaged or worn crown can be repaired or replaced in some cases without remaking the entire framework.

Whether a crown can be removed individually depends on:

- The connection between the crown and framework;

- Interproximal contacts;

- The extent of prosthetic gingival coverage;

- The location of the damage;

- Whether the framework is distorted;

- Whether the prosthesis can be removed intact.

For this reason, the recommended product-page wording is “supports easier individual crown repair or replacement”, rather than a guarantee that every crown can be replaced in all circumstances.

A Malo Bridge is typically used as a definitive fixed prosthesis.

During implant surgery or healing, the patient may initially receive a PMMA or resin provisional bridge. Once osseointegration is complete and the soft tissues and occlusion are stable, a definitive Malo Bridge with a titanium framework and individual all-ceramic crowns can be fabricated.

Provisional and definitive bridges differ in materials, structure, fit, and intended use and should not be presented as the same product. Full-arch treatment commonly progresses from a fixed provisional bridge to a definitive prosthesis once the tissues have stabilized.
