When is selective full-mouth rehabilitation appropriate?

The extent should follow wear activity, symptoms, prognosis, function, patient priorities and the ability to control causes.

An increase in vertical dimension is a diagnostic choice, not an automatic part of every rehabilitation.

Selective full-mouth rehabilitation can be appropriate when tooth wear is localized or when the remaining dentition is still biologically and functionally stable. The presence of worn teeth alone does not necessarily justify restoring every tooth. The key question is whether the existing occlusion can remain functional and whether the affected teeth can be treated predictably without unnecessarily involving otherwise healthy teeth.

I would start by identifying the cause and activity of the wear. Attrition from bruxism, erosion, abrasion, dietary or occupational factors can produce very different treatment requirements. Periodontal condition, caries risk, pulpal status, remaining tooth structure, existing restorations, posterior support and the patient's symptoms should all be assessed before deciding on the extent of treatment. A comprehensive examination is particularly important because severe wear can exist with or without an actual loss of occlusal vertical dimension.

Selective treatment becomes more reasonable when the majority of the dentition remains sound, the occlusal relationship is reasonably stable, there is adequate restorative space, and the worn or missing teeth can be restored without creating a new occlusal problem. For example, replacing strategically important missing posterior teeth or restoring a limited group of structurally compromised teeth may provide sufficient function without preparing an entire arch.

Comprehensive rehabilitation becomes more appropriate when the problems are generalized and interconnected. Examples include extensive tooth wear combined with loss of posterior support, multiple failing restorations, widespread structural damage, significant tooth loss, or a clinically relevant alteration of the occlusal relationship. In these situations, treating individual teeth independently can make it difficult to control the overall function, restorative space and occlusal scheme.

One particularly important distinction is whether the vertical dimension actually needs to be changed. Historical classifications of worn dentitions distinguish cases with loss of vertical dimension from cases where the vertical dimension has been maintained despite substantial wear. This distinction can significantly influence whether a clinician needs to reorganize the occlusion or can work within the patient's existing relationship.

I would also avoid making the decision based on tooth appearance alone. Diagnostic records such as photographs, study models or digital scans, radiographs, periodontal assessment and occlusal records help establish how much of the problem is biological, structural and functional. If an increase in occlusal vertical dimension is being considered, an evaluation phase with provisional restorations can be useful because it allows assessment of function, phonetics, aesthetics and patient adaptation before definitive treatment. Recent consensus work specifically addresses this evaluation approach in worn dentitions.

Another useful principle is to preserve healthy tooth structure whenever possible. Modern approaches increasingly favor additive and minimally invasive techniques where clinically appropriate rather than automatically reducing multiple otherwise serviceable teeth simply to create a conventional full-mouth reconstruction.

So, in practical terms, I would think of the decision as a spectrum rather than a choice between two fixed protocols:

• Localized wear with stable function → selective restorative treatment may be sufficient.

• Moderate generalized wear with adequate space and stable occlusion → selective or staged rehabilitation may be appropriate.

• Generalized structural damage, loss of posterior support, multiple failing restorations or significant occlusal instability → comprehensive rehabilitation deserves consideration.

The final plan should therefore be driven by diagnosis, prognosis, function and the amount of sound tooth structure that can be preserved, rather than by the visual severity of wear alone. The literature also emphasizes that no single occlusal philosophy is universally applicable to every worn dentition.

For readers interested in the practical side of complex worn dentition cases, Andent has a relevant article, “Full Mouth Restoration in Albania: Worn Teeth, Bite Collapse and Your Options,” which discusses diagnostic planning, selective implants, crowns and bridges, full-arch options, provisional restorations and treatment sequencing:

Clinicians can decide by assessing the extent, cause, symptoms, and functional impact of tooth wear.

Selective treatment is usually appropriate when wear is localized or mild, the remaining teeth are stable, and the patient has acceptable function and aesthetics. Treatment may involve monitoring, small restorations, occlusal adjustment, or treating the specific cause. Comprehensive rehabilitation is considered when wear is generalized and advanced, with loss of tooth structure, reduced function or vertical dimension, multiple failing restorations, sensitivity, pain, or significant aesthetic concerns. Clinicians should also identify and control contributing factors such as bruxism, erosion from acidic foods/drinks, abrasion, and dietary or medical causes. The decision should be based on a full clinical examination, photographs, radiographs when indicated, occlusal assessment, and the patient's symptoms, expectations, and long-term prognosis.
