| Abstract | ||||
| Aim: The aim of this study was to radiographically evaluate the effect of using double OT Cap attachment on the supporting structures of unilateral partial denture cases with different saddle length using the Digora imaging system. Methodology: 16 patients with unilateral distal extension partially edentulous lower arches with last standing abutment 4 or 5 were selected in this study. Patients were rehabilitated with a unilateral RPD retained with a double OT Cap attachment where the last abutment is the 2nd premolar in group I & 1st premolar in group II. The lower 4 & 5 on the distal extension side in group I were prepared to receive a ceramo-metallic 2-unit fixed crowns, the same was done for 3&4 in group II. Crowns with their attachments were cemented to the abutment teeth and denture was delivered to the patient. Marginal bone height changes around abutments & residual ridge posteriorly were measured by Digora system. Data were collected at different follow-up intervals tabulated and statistically analyzed by Tukey`s post hoc test and t-test for comparison between groups. Results: Results of this study showed a significant difference as P < 0.05 in all intervals regarding overall 1st & 2nd abutment & distal extension ridge, bone changes in group II was significantly higher than group I. Conclusion: With in the limitation of this study, it could be concluded that attachment retained partial dentures with OT unilateral attachment provide less bone height changes around the abutment & in the posterior area in short saddle cases. | ||||
