Abstract
Purpose: The purpose of this study was to evaluate the internal fitness of the resin coping that was fabricated by the
traditional and Digital manufacturing methods through 3-dimensional analysis.
Methods: maxillary right second molar was chosen implant master model. Custom-built impression trays were
manufactured. After screwing the pick-up impression coping onto the master cast, impressions were made with silicone
impression. The Working model was then made with type IV stone. The coping was fabricated: SLAC group (n=8), APPC
group (n=8), LAPC group (n=8) Resin coping data was measured by using a three-dimensional evaluation program. Internal fitness was calculated by RMS (Root Mean Square).It measures mean and Standard Deviation (SD).
Results: Three groups are measured 47.11±(3.08)㎛ total RMS of SLAC group, 48.35(±1.55㎛) for total RMS of LAPC
group, 43.45±2.09㎛ for total RMS of APPC group. Measured value is gradually increased. Followed by autopolymerized
pattern resin; Stereolithography resin, Light-activated pattern resin But there were no differences stastically(P>0.321).
Conclusion: Evaluation of internal fitness on Resin copings was fabricated by three?ways methods showed that no
differences statistically significant and clinically acceptable results.
