Posterior Bite Collapse and Diagnostic Grading for Periodontitis
The International Journal of Periodontics & Restorative Dentistry
|February 2, 2021
Summary
Posterior bite collapse (PBC) lacks a clear definition, complicating its classification within Stage IV periodontitis. This study reexamines PBC
Area of Science:
- Periodontology
- Dental Diagnostics
Background:
- Posterior bite collapse (PBC) has evolved definitions since its 1964 introduction.
- The 2017 World Workshop includes Stage IV periodontitis, potentially encompassing PBC.
- Lack of clear clinical and pathogenetic criteria for PBC hinders its definition.
Purpose of the Study:
- To re-evaluate the original definition of Posterior Bite Collapse (PBC).
- To propose an updated definition for PBC.
- To introduce a clinical grading system for PBC aligned with the 2017 periodontitis staging.
Main Methods:
- Literature review of original PBC definitions.
- Analysis of clinical presentations and pathogenetic factors.
- Development of a proposed grading system.
Main Results:
- The original definition by Amsterdam and Abrams is reviewed.
- An updated definition of PBC is presented.
- A clinical grading system for PBC is proposed.
Conclusions:
- A refined definition and grading system for PBC are necessary.
- This framework aims to clarify PBC's role within periodontitis staging.
- Standardizing PBC classification improves diagnostic accuracy and treatment planning.
