Abstract
Introduction: Removable partial dentures (RPDs) are considered an economic and good treatment modality compared with most costly alternatives like dental implants. CAD/CAM technology has improved the fit of RPDs, improving efficiency and manufacturing results.
Aim of this study: This study was conducted to compare adaptation between 3D printed frameworks and conventionally constructed ones in mandibular Kennedy class I.

Materials and methods: A model of mandibular Kennedy class I was used. A total of 12 frameworks were constructed over the model and divided into 2 groups. Six frameworks in each group according to fabrication method: Group I, 3D printed metal frameworks; Group II conventional method (Lost-wax technique). RPD frameworks were constructed from cobalt-chromium alloy. The frameworks were optically scanned, and the distances from the original master model at various points were measured for adaption comparison.
Results: Group I showed less deviation in comparison to Group II with a statistically significant difference (p-value <0.05).
Conclusion: Within the limitations of this study it was concluded that:
The 3d printed manufactured frameworks showed higher adaptation and fitness, with smaller discrepancies relatively to that frameworks conventionally constructed by casting technique.
