Abstract

Objective: The present study assessed the influence of gingival biotypes and retraction methods on the quality of two stage putty impressions.
Methodology: A total of 518 documented and completed FPD cases were selected for assessment of gingival biotype, retraction cords used and degree of flash achieved in master impression. The prevalence of gingival biotype and its association with the combination of cords used and the quality of two-stage putty impressions obtained was evaluated using descriptive statistics.
Results: A statistical significant correlation (p=0.024) was found between the gingival biotypes and quality of the master impression (function of degree of flash). A 360° flash was significantly higher in the scalloped and thin gingival type (55% cases). A significant correlation between the biotype and the combination of retraction cord used (p<0.05).
Conclusion: Based on our study, use of 00+1 or 000+1 gingival retraction cords is advised for thin gingival biotypes which in turn would help in achieving a greater quality of impression and preserve the periodontal attachment for survival of the prosthesis.
