Introduction: Over-denture treatment concept is about the removable complete denture that overlies retained teeth, tooth roots, or dental implants. This treatment option is not a recent concept, and has been successfully employed in existing tooth structures or retained roots to assist with complete denture treatment. The healthy periodontal ligament indicates healthy alveolar ridge morphology, whereas a diseased periodontal ligament, or its absence, is associated with inevitable time-dependent reduction in residual ridge dimensions. Materials and methods: A comparative study was conducted among a total of 38 patients who were treated and evaluated over the period of 18 months. Patients were divided into two groups, group A had 19 patients who opted for conventional root supported over-denture. Group B had 19 patients who opted for root supported over-dentures with precision attachment. Results: All the response were recorded manually and interpreted electronically. Out of 19 patients in group A, 5 patients (26%) complained of denture rocking and discomfort while chewing. 3 patients (16%) complained discomfort while speaking. None of the patients complained about the esthetics, problems with removal and insertion or cleaning and maintenance. Out of 19 patients of group B, 2 patients (11%) complained about discomfort while chewing, 1 patient (5%) patient complained about poor phonetics, 7 patients (37%) complained about difficulty in removal and insertion and 3 patients (16%) complained about difficulty in cleaning and maintaining oral hygiene. Conclusion: Root supported over-denture with precision attachment prosthesis are a simple and a cost effective alternative treatment to prefabricated attachments for enhancing the retention of tooth supported over-dentures. Also, the root supported over-denture with precision attachment are poor in terms of oral hygiene when compared with tooth supported over-dentures.
