Analysis of Border Molding using Different Impression Techniques- A Clinical Study
Vishal Singh

Background: The ability of complete denture to perform retention, stability and mastication makes a treatment successful. The present study was conducted to determine the retention force of impressions made by two different techniques. Materials and methods: The present study was conducted in the department of Prosthodontics. It comprised of 8 patients of both genders. Patients were divided into 2 groups. Group I were those in which single step border molding technique was used and group II comprised of those patients in which sectional technique was used. Primary impression was taken with irreversible hydrocolloid. Two trays were made which were 2-3 mm short of the sulcus depth. Single step border molding with low fusing impression compound was used with first tray. With second tray, sectional border molding technique was done. The recording of the denture retentive force was carried out with digital force meter. Results: Two techniques such as single step and incremental border molding technique was used. Out of 8 patients, males were 5 and females were 3. The difference was significant (P- 0.01). The mean retentive force in group I was 8.34 and in group II was 9.14. The difference was significant (P< 0.05). Conclusion: The sectional border molding technique was more retentive than single step technique. The choice of border molding technique depends upon the condition of the alveolar ridge and the choice of the operator.
