Background:
Present study was performed to assess the biologic width relocation by performing aesthetic crown lengthening with the help of Chu aesthetic gauges.
Methods:
The study included 192 teeth from 17 individuals, of which 64 teeth underwent crown lengthening (Treated site- TS) and 128 of which shared a proximal surface (Adjacent site -AS, Non-Adjacent site- NAS) with the surgery site. The clinical parameters Plaque index (PI), gingival index (GI), gingival margin position (PGM), relative attachment level (RAL), bone sounding (BS), biological width (BW), and probing depth (PD) were recorded. The clinical recordings were made at three different times: at baseline, 3 and 6 months post-operatively. Statistical analysis was performed using one way ANOVA and for pair wise comparisons post hoc Tukey test was used. Data was expressed in mean and standard deviations. P < 0.05 was considered statistically significant.
Results:
PI and GI showed significant difference (p = 0.000*) at all time intervals. PGM and RAL were significant from baseline to 3 months, baseline to 6 months (p = 0.000*) while non-significance (p > 0.05) was recorded at 3-6 months comparison for PGM, RAL, BS, BW and PD.
Conclusion:
Present study concluded that usage of Chu Aesthetic gauges help in controlled removal of soft and hard tissues, biologic width and gingival margin position got stabilized within 3 months and final prosthesis can be advised after 3 months of surgery.
