심미도재수복시의 와동의 폭과 교두의 capping이 응력의 분포에 미치는 영향을 비교하기 위하여 연속사진 촬영술을 이용하여 상악제1소구치의 3차원 유한요소 모델을 제작하였다. 법랑질, 상아질, 도재 및 복합레진시멘트의 각각의 재질에 대한 물성치를 부여하고, 140N의 하중을 가하여 Super SAP 프로그램으로 해석하여 다음과 같은 결과를 얻었다. 1. 응력은 탄성계수값이 큰 법랑질과 도재를 따라 분포되고, 연질의 상아질에는 적게 발생된다. 2. 와동의 협측치수선각부위에서는 인레이모델의 경우에는 와동폭의 증가에 따른 응력의 증가는 관찰되지 않으나, 온레이모델에서는 응력의 증가가 관찰된다. 3. 온레이모델의 경우에는 근심협측교두를 피개하고 있는 도재부위에 최대주응력이 크게 나타나고, 치은변연부의 도재에서는 교두를 피개하지 않은 인레이모델의 해당되는 법랑질에 비해 응력이 1/2정도로 감소된다. 4. 하중이 증가되면 잔존치질의 파절은 근심와동의 협측치은선각부위에서 협측보다는 치은을 향해 경사지게 일어날 것이다. 5. 교두를 피개하면 교두피개부위에서의 도재의 파절가능성은 증가되고, 치은변연에서는 도재와 하부의 치질의 파절가능성은 감소된다. 6. 도재를 이용하여 교두를 피개할 경우에는 응력을 견딜 수 있는 도재의 두께를 부여할 수 있도록 교두를 충분히 삭제하여야 하고, 충분한 강도를 갖는 도재를 선택하여야 한다.

Objectives: The aim of this study was to investigate the characterization of composite resin inlay surface with silane and non-thermal atmospheric pressure plasma treatment. Methods: Composite resin inlay was used as a specimen, which was treated by sandblasting + silane and sandblasting + plasma. The untreated specimens were assigned to the control group. Specimens were analyzed for surface roughness, color change, and chemical composition. Statistical analyses were performed using one-way ANOVA test (p<0.05). Results: The present findings showed that the roughness and color changes of the plasma-treated surface were significantly lower than those of the silane-treated surface. In addition, a change in the chemical composition was observed on the plasma-treated surface. Conclusions: Based on the results, non-thermal atmospheric pressure plasma could be a potential tool for the cementation of composite resin inlay.

Objectives: This study was aimed to determine the effects of temporary sealing materials on microtensile bond strength between resin-coated dentin and resin inlay and to compare the bonding effectiveness of delayed dentin sealing and that of immediate dentin sealing. Materials and Methods: The teeth were divided into 4 groups: group 1, specimens were prepared using delayed dentin sealing after temporary sealing with zinc oxide eugenol (ZOE); group 2, specimens were prepared using immediate dentin sealing and ZOE sealing; group 3, specimens were prepared using immediate dentin sealing and Dycal (Dentsply) sealing; group 4, specimens were prepared using immediately sealed, and then temporarily sealed with a resin-based temporary sealing material. After removing the temporary sealing material, we applied resin adhesive and light-cured. Then the resin inlays were applied and bonded to the cavity with a resin-based cement. The microtensile bond strength of the sectioned specimens were measured with a micro-tensile tester (Bisco Inc.). Significance between the specimen groups were tested by means of one-way ANOVA and multiple Duncan's test. Results: Group 1 showed the lowest bond strength, and group 4 showed the highest bond strength (p < 0.01). When temporary sealing was performed with ZOE, immediate dentin sealing showed a higher bonding strength than delayed dentin sealing (p < 0.01). Conclusions: Based on these results, immediate dentin sealing is more recommended than delayed dentin sealing in bonding a resin inlay to dentin. Also, resin-based temporary sealing materials have shown the best result.

The purpose of this study is to evaluate the effects of surface treatment and composition of reinforcement material on fracture strength of fiber reinforced composite inlay bridges. The materials used for this study were I-beam, U-beam TESCERA ATL system and ONE STEP(Bisco, IL, USA). Two kinds of surface treatments were used; the silane and the sandblast. The specimens were divided into 11 groups through the composition of reinforcing materials and the surface treatments. On the dentiform, supposing the missing of Maxillary second pre-molar and indirect composite inlay bridge cavities on adjacent first pre-molar disto-occlusal cavity, first molar mesio-occlusal cavity was prepared with conventional high-speed inlay bur. The reinforcing materials were placed on the proximal box space and build up the composite inlay bridge consequently. After the curing, specimen was set on the testing die with ZPC. Flexural force was applied with universal testing machine (EZ-tester; Shimadzu, Japan). at a cross-head speed of 1 mm/min until initial crack occurred. The data was analyzed using one-way ANOVA/Scheffes post-hoc test at 95% significance level. Groups using I-beam showed the highest fracture strengths (p<0.05) and there were no significant differences between each surface treatment (p>0.05) Most of the specimens in groups that used reinforcing material showed delamination. 1. The use of I-beam represented highest fracture strengths (p<0.05) 2. In groups only using silane as a surface treatment showed highest fracture strength, but there were no significant differences between other surface treatments (p>0.05). 3. The reinforcing materials affect the fracture strength and pattern of composites inlay bridge. 4 The holes at the U-beam did not increase the fracture strength of composites inlay bridge.
