What is the periodontal response to a newly placed restoration that interferes with occlusion?

The correct response indicates that the placement of a restoration interfering with occlusion can lead to thickening of the periodontal membrane. When a restoration is not aligned properly with the occlusion, it can lead to excessive or uneven forces being applied to the teeth and supporting structures during biting and chewing. This alteration in occlusion can cause the periodontal membrane, which surrounds the tooth root and provides support, to respond to increased forces.

As a result, the periodontal tissues adapt to these changes, and this often manifests through the thickening of the periodontal membrane. This thickening is a compensatory response as the body attempts to reinforce the structures in the face of additional stress, potentially resulting in initial inflammation as well.

Other choices describe possible issues stemming from periodontal abnormalities, including increased bleeding, gum recession, or abscess formation, but thickening of the periodontal membrane specifically addresses the response to occlusal interference from a newly placed restoration. This understanding is crucial for dental practitioners as they assess and manage such restorations to ensure optimal occlusal function and periodontal health.
