Background: Functioning of a complete denture depends to a great extent on the impression technique. There are various factors associated with the retention of complete dentures, which may be broadly grouped as biological, physical and mechanical. The peripheral margins of the denture at all the points should be so formed that the tissues, when at rest or under muscular tension, will remain in close contact with the margins, thus preventing the ingress of air between the denture and tissues. Aim of the study: To compare efficacy of two border molding techniques on maxillary complete denture retention. Materials and methods: The study was conducted in the Department of Dentistry of Shridevi Institute of Medical science and research hospital, Tumakuru, Karnataka. For the study, we randomly selected 7 completely edentulous patients who reported to the department seeking prosthodontic rehabilitation. The age of the patients ranged from 40-70 years. Patients with well formed residual alveolar ridges, no severe undercuts or bony exostosis, firm mucosa, no inflammation or ulceration and having normal TMJ function were selected for the study. Patients having high palatal vaults were excluded from the study. For each patient, the primary impression was made with Hydrocolloid impression material in a perforated tray and was poured in dental stone to obtain primary cast. For sectional border molding, low fusing impression compound was used and procedure was done by following the guidelines. For single step border molding an injectable heavy viscosity PVS was used according to the given guidelines. Results: In the present study, the retention of denture formulated with single-step border molding and sectional border molding was compared for 7 subjects. We observed that in all the subjects, the denture bases formulated by sectional border molding technique has more retention as compared to single step technique. As per statistical analysis, the results are statistically significant. Conclusion:  From the results of the present study, this can be concluded that both the techniques of border molding discussed in this study, single step border molding and sectional border molding, offer satisfactory retention, however, sectional border molding is more efficient with respect to the retention.
Key words: Border molding, sectional border molding, single step border molding, retention.
