PURPOSE: To investigate whether there was any difference in anterior capsular opening area between the use of silicone intraocular lens(IOL) and acrylic IOL after continuous curvilinear capsulorhexis(CCC). METHODS: In 42 eyes, acrylic IOL(Acrysof(R), Alcon, U.S.A.) were inserted into the capsular bag during phacoemulsification, and in 36 eyes silicone IOL(Chiroflex II(R) , Chiron, U.S.A.) were inserted. The reduction rate of anterior capsular opening area at first, second, third and sixth postoperative month were compared between the two groups. RESULTS: On the whole, the reduction in anterior capsular opening area was larger by 0.574 mm 2 when silicone IOL was used, but the different was not statistically significant(P= .061). The result was the same at 1 month(P= .149), 2 months(P= .144), 3 months(P= .223), 6 months(P= .163) after surgery. CONCLUSIONS: We concluded that there was little difference in the changes of anterior capsular opening area after CCC between the use of silicone IOL and acylic IOL, and other factors should be considered.

As the inaccuracy which was made in implant impression prevented passive fit,it needed to solder the sectioned framework at several locations to correct the inaccuracy. Many clinicians have suggested impression techniques which could make passive fit between implant and superstructure. The purpose of this research was to measure and compare the accuracy of three methods of taking impression with the strain amplifier. The experimental groups were classified as follows : Group I; splinted the two parts with Futar D Occlusion. Group II; splinted the two parts with DuraLay. Group III; didn't splint the two parts. The results were as follows ; 1.The values of strain in the vertical and horizontal surfaces were increased in the order of groupI,group II and group III. 2.Group I showed higher accuracy of the duplicated casts in the vertical and horizontal surfaces than group IIand group III(p<0.05). 3.There were no significant differences in the accuracy of the duplicated casts between group IIand groupIII. From the above results,it is considered that the splinting method of impression copings could make an influence on the accuracy of the master casts.To improve the accuracy of the master casts, splinting the squared impression copings with the additional silicone occlusion materials is recommendable.

9.In vitro evaluation of resonance frequency analysis values to different implant contact ratio and stiffness of surrounding material.
The Journal of Advanced Prosthodontics 2013;5(4):428-433
PURPOSE: The present study was aimed to evaluate the influence of implant contact ratio and stiffness of implant-surrounding materials on the resonance frequency analysis (RFA) values. MATERIALS AND METHODS: Seventy resin blocks that had the different amounts (100, 50, 30, 15%) of resin-implant contact (RIC) were fabricated. Ten silicone putty blocks with 100% silicone-implant contact were also made. The implants with O5.0 mm x 13.0 mm were placed on eighty specimen blocks. The RFA value was measured on the transducer that was connected to each implant by Osstell Mentor. Kruskal-Wallis and Scheffe's tests (alpha=.05) were done for statistical analysis. RESULTS: The control resin group with 100% RIC had the highest RFA value of 83.9, which was significantly different only from the resin group with 15% RIC among the resin groups. The silicone putty group with 100% contact had the lowest RFA value of 36.6 and showed statistically significant differences from the resin groups. CONCLUSION: Within the limitations of this in vitro study, there was no significant difference in the RFA values among the resin groups with different RIC's except when the RIC difference was more than 85%. A significant increase in the RFA value was observed related to the increase in stiffness of material around implant.
