Abstract

Statement of the Problem: Border molding is one of the important biologic factors required to provide optimal retention of the denture by creating a peripheral seal.
Purpose: Previous studies have evaluated different materials individually for the purpose of border molding. The literature does not report about comparative evaluation of the efficiency of different materials for the purpose of one step border molding. This clinical study compares and evaluates the effectiveness of different materials for the purpose of one step border molding.
Aims: To evaluate and compare the effectiveness of different materials for the purpose of one step border molding.
Methods and Material: One step Border molding was completed for each subject by manual manipulation of the soft tissues adjacent to the tray borders using three different materials -1) Low fusing Impression Compound Type I b, 2) Heavy bodied Elastomeric Material : Polyvinyl Siloxane and 3) Modified Zinc Oxide Eugenol Impression Paste. Three examiners evaluated the border molding based on tissue contact, tissue displacement, bond to the tray and overall peripheral seal. Each criteria was scored on a scale of 1-5, with score 1 as bad while score 5 was considered excellent. The average of the score recorded by the three examiners for each criteria was considered.
Results: Heavy Bodied Elastomeric Material- Polyvinyl siloxane has the best efficiency, while Low fusing Impression Compound Type I a had the least efficiency amongst the three when used for the purpose of border molding.
Conclusions: One step border molding is an viable and advantageous alternative to conventional border molding (sectional border molding) as it results in reduction of chairside time, less discomfort for the patient and less efforts for the dentist.
