COMPARATIVE ANALYSIS OF TWO BORDER MOLDING TECHNIQUES AND MATERIALS ON MAXILLARY COMPLETE DENTURE RETENTION- AN IN-VIVO STUDY
Renu Gupta, RP Luthra, Savisha Mehta

Background - Without question, the conventional border molding procedures using modelling compound have served the dental profession well and will continue to serve the profession for many years,but has many limitations. Therefore, it is important that the profession continuously strives to develop new procedures aimed at improving accuracy, convenience, and patient acceptance. Purpose - This study was performed on 20 healthy edentulous subjects to compare the retention of complete dentures made by using two different border molding materials and border molding techniques i.e. green stick with incremental technique and heavy bodied polyvinylsiloxane with simultaneous technique. Material and method- In this study, retentive values were evaluated for sectional border molding  using modelling compound (Group A) and single step border molding using heavy bodied polyvinylsilloxane (Group B) after fabricating trail denture bases usng a specially designed retention apparatus and a digital force gauge.
Reults - There was a statistically significant difference in retention between the two materials. Heavy body polyvinylsilloxane showed the higher mean value. However, on clinical evaluation the retention received by both the denture bases was acceptable. Summary and conclusion - Within the limitation of this clinical study border molding with heavy bodied polyvinyl siloxane using simultaneous technique provided better retention as compared to border molding with modelling compound using incremental technique.
Keywords- border molding, green stick, polyvinylsiloxane, impression, retention.
