Why it matters for dental

Overhanging proximal restorations are associated with significantly worse periodontal outcomes, so restorative dentists and hygienists must prioritize overhang removal or re-treatment to protect attachment levels and reduce future perio costs.

Key points

  • Meta-analysis pooled data from multiple clinical studies to quantify the effect of overhangs on probing depth, clinical attachment loss, and bleeding on probing.
  • Overhangs >0.5 mm showed a statistically significant increase in periodontal inflammation and attachment loss versus flush or sub-contour restorations.
  • Findings apply directly to daily operative decisions: finishing margins, matrix choice, and post-op evaluation of contacts.
  • Clinicians treating perio-restorative patients can use the data to justify re-contouring or replacement of defective restorations as part of non-surgical periodontal therapy.
