Abstract
Tooth mobility in periodontitis represents a clinically relevant finding associated with loss of periodontal support, functional impairment, and patient discomfort. Beyond its diagnostic value, mobility may influence treatment planning and the predictability of therapeutic outcomes, particularly in advanced stages of disease.

Tooth splinting has been proposed as an adjunctive approach aimed at improving functional stability and redistributing occlusal forces, thereby facilitating periodontal therapy. Its indication remains selective and should be based on a comprehensive clinical evaluation integrating periodontal status, occlusal factors, and restorative considerations.

A structured clinical approach to adhesive extracoronal splinting in periodontally compromised dentitions is outlined. Emphasis is placed on the key principles guiding its application, including appropriate case selection, ensuring passivity, and maintaining access for oral hygiene.

Practical aspects related to clinical workflow, material selection, and the limitations of the method are also briefly addressed. While most applications are directed toward the mandibular region, specific considerations may arise in other clinical situations.

Overall, tooth splinting is presented as an adjunctive intervention integrated within a comprehensive periodontal treatment plan, with the aim of improving function and patient comfort in the short, medium, and long term.
