Aim: To evaluate of retentive value of tooth supported over denture made with precision (Pre-fabricated) and semi-precision (Castable) attachments. Materials and Methods: 24 Acrylic edentulous models were prepared and randomly divided into 2 groups. Group group A consist of Pre- Fabricated Pivots were directly embedded in Acrylic Model with Auto-polymerized Resin. In group B Casting, Finishing & Polishing of Castable Pivots were done and embedded in Acrylic Model. Denture bases with three loops approximating incisor and molar regions were made for testing in each acrylic models. Yellow retentive caps (Rhein 83) and stainless steel housings (Rhein 83) were embedded in denture base using direct pick up technique. Three chains were attached to the Record base and a 3-point vertical pull was used to determine retention against a vertically directed dislodging force parallel to the path of insertion. Result: Mean retentive value of Pre-fabricated Attachment/ Precision Attachment group (4.71 ? 0.09 N) was higher than mean retentive value of Castable Attachment group (4.18 ? 0.12 N). Statistically, significant difference was present in mean retentive values of two groups. (p ≤ 0.05) Conclusion: Within the limitation of this study it can be concluded that use of semi-precision attachment could be cost effective treatment modality without compromising optimal retentive value for tooth supported overdenture
