Why it matters for dental
Periodontists and restorative dentists performing aesthetic crown lengthening can consider either piezosurgery or rotary burs for ostectomy, as both techniques produced comparable gingival margin stability over six months.
Key points
- 01
Fifteen patients with altered passive eruption received split-mouth aesthetic crown lengthening from maxillary premolar to premolar.
- 02
Primary outcome measured gingival margin change between 6 weeks and 6 months: 0.16 ± 0.19 mm (piezosurgery) versus 0.12 ± 0.21 mm (rotary burs), with p = 0.170.
- 03
Largest crown height reduction occurred between suturing and 7 days post-surgery (−0.63 ± 0.35 mm).
- 04
Cemento-enamel junction to bone crest remodelling from surgery to 6 months showed no significant difference between techniques (−0.22 ± 0.42 mm piezosurgery vs −0.26 ± 0.44 mm rotary burs).
