Comparison of The Surface Area Coverage of The Impressions Made of Impression Compound And Alginate: An in Vitro Evaluation.
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 12
Abstract
Introduction: The history of complete denture impression procedures have been influenced largely by the development of impression materials from which new techniques arose. Selection of material is left to the desertion of the dentist, who makes choices based on personal preferences and experience. This study has been conducted to compare the surface area coverage in the maxillary and mandibular primary impressions using alginate and impression compound. Materials & method: A total of 20 primary maxillary impressions and 20 mandibular primary impressions are made; out of which 10 primary maxillary and 10 mandibular primary impressions are made using impression compound and remaining 10 primary maxillary and mandibular impressions are made using high viscosity alginate. After disinfection, the casts were poured using dental plaster and divided in two groups. The examinations for surface area coverage were performed on the plaster models using sketch and cal software. The results for the surface area coverage were subjected to the two way ANOVA statistical test. Result: In Intragroup comparison of group 1, Subgroup 1 recorded surface area of 18.87 ± 0.357 cm2 where as Subgroup 2 recorded surface area of 11.69 ± 0.248 cm2 . In intragroup comparison of group 2, Subgroup 1 recorded surface area of 23.062 ± 0.468 cm2 where as Subgroup 2 recorded surface area of 14.678 ± 0.311 cm2 . In intergroup comparison between two groups, group 2 (Impression compound) recorded mean surface area of 37.44 ± 0.113 where as group 1 recorded surface area of 30.56 ± 0.233 cm2 . Conclusion: The impression compound is a better material for fabricating complete denture for edentulous patients as compared to alginate in terms of surface area coverage. Maxillary arches are found to have more surface area as compared to their counterpart mandibular arches.
