2 mm titanium plates vs 2.5 mm bioresorbable plates

Requirement for additional (surgical) interventions (plate removal / re-operation) · Adults (16 to 68 years) with mandibular fractures excluding condylar involvement
1 finding from 1 review
  • Plate removal was statistically more likely in the titanium group (Fisher's exact P<0.05); infection led to plate removal in one titanium participant at 2 months and a further 4/21 (19%) titanium participants (six…
