Sculpture/FibreKor

DESCRIPTION: The Sculpture/FibreKor system unites the latest in polymer ceramics and advanced fiber　science technology allowing the laboratory　technician to create functional　and esthetic restorations. FibreKor is　a pre-impregnated fiber reinforcing

material with a modulus of rupture　comparable to non-precious alloys (approximately

1000 MPa). FibreKor is　used, in place of metal, to reinforce　single unit and three-unit bridges.　Sculpture is an advanced light, heat,and vacuum cured polymer-glass restorative　material that is built on the　FibreKor substructure. Sculpture has　an extremely low water absorption rate　(9-12mg/mm), which prevents unsightly　discoloration or staining. A　Sculpture restoration is projected to　have a wear rate similar to that of natural　dentition—less than 3 microns per　year. Studies available upon request.

Sculpture/FibreKor系统（KERR公司）

概述：Sculpture/FibreKor系统将最新的聚合瓷与先进的纤维科技结合起来，采用此系统技师可以创造出功能与美观都兼顾的修复体。FibreKor是一种预浸润的纤维，与非贵金属相比，可以增加材料的抗折能力，使其抗折强度高达1000MPa。这种纤维还可以用于替代金属，用于加强一个单位到三单位的桥体。Sculpture可以与FibreKor结合，是一种先进的光，热，真空固化的聚合体－玻璃类修复材料。Sculpture有极低的吸水率（9～12毫克每毫米），这个特点可以阻止不可预见的变色与外染色。Sculpture修复体其磨损率与天然牙列类似――每年小于3微米。相关研究还需等待。

INDICATIONS: Anterior and posterior　crowns, full coverage bridges, inlay/onlay bridges, encore bridges, inlays　and onlays. Bridges should not　exceed 15 mm in length.

PREPARATION: Preparation is accomplished　with common, commercially　available high-speed burs. Inlays/　onlays should be prepared to avoid　undercuts or thin tapered areas to　maintain passive fit. Finish lines　should be 90°-100° shoulders or deep　chamfers. Full coverage crowns are prepared　with 360° circumferential, super　gingival shoulders. Reduction is　similar to, or slightly less than conventional　porcelain-fused-to-metal. Avoid　sharp angles, undercuts, and beveled　or “feather edge” finish lines. On crown　abutments a small 2x2x2 mm box is　added at the proximal-occlusal line　angle to support FibreKor structural　bars. Veneers are prepared, as they　would be for ceramics.　

牙体预备：牙体预备采用常规高速车针即可。嵌体与高嵌体应该避免倒凹与尖锐区以保证被动就位。边缘线采用90～100度肩台或深凹边缘。牙体预备量与常规金属烤瓷冠类似或稍有不同。避免锐角、倒凹、斜面及羽状边缘。冠基牙的邻合线角需要增加一个2×2×2mm的盒形以支持FibreKor带状纤维结构。贴面预备与瓷贴面预备一致。

CEMENTATION: Contemporary　bonding and resin luting techniques　are recommended.

粘接：需使用现代树脂粘接。

SHADE SELECTION: Shades are　matched to the Vita Lumin shade　guide.FibreKor is offered in five shades　(A,B,C, and D ranges) and two sizes.

比色：采用VITA16色。FibreKor纤维有5个牙色(A, B, C与D系列)及两种尺寸。

注解：

encore bridges实际上就是一种粘接侨，下面一段是我找到的一段解释以及病例：

One extremely esthetic type of tooth replacement is the Encore? bridge. This restoration can be used if the teeth on either side of the missing tooth do not have crowns or other large restorations. Besides being very esthetic, it does not require the dentist to grind down the adjacent teeth. The principal disadvantage is that it is not quite as solid as a conventional porcelain-to-metal dental bridge and there is a slight risk of it breaking or coming loose. It also requires a high degree of skill to place properly. Do not ask your general family dentist to place one of these types of tooth replacement. To find an expert cosmetic dentist, please visit our cosmetic dentist referral page.

In placing an Encore? bridge, the cosmetic dentist cuts a space similar to what he or she would do for a filling in each of the two adjacent teeth. Then a framework of tough, fiber-reinforced tooth-colored resin is bonded into those filling spaces, and this framework spans the space of the missing tooth. After bonding in the framework, a porcelain veneer is bonded onto the front of the framework to simulate a natural tooth. The result is extremely natural, and it is difficult to tell from the front that anything artificial is present in the mouth.

Encore bridges是一种比较美观的修复体。这种修复体可用于两侧基牙没有修复体或大的充填体的情况。 除了比较美观外，并不需要牙医磨缺牙两侧的健康牙齿。其主要缺点是不如传统的金属烤瓷桥坚固，有轻度的折裂与松动的风险，还需要牙医有很高的技巧来准确就位。不要去请你的 全科牙医来制作这样的修复体，需要找专门的牙齿美容医生。

制作Encore bridges时，牙医需要在两侧牙齿上做一定的牙齿预备以为修复体放置准备空间。然后坚固的纤维增强过的牙色树脂的桥架粘接到邻牙舌侧预留间隙。粘接好树脂桥架后，在桥架的唇侧制作并粘接瓷贴面以模仿天然牙。结果非常自然，。。。。见下面示意图。

Below is an example of an Encore? bridge case. This work was done by Dr. Gary Radz,

Here is another photograph of an Encore? bridge case.

Thi s case was supplied to us by Opus One Dental Lab in California. This patient has intact teeth on either side of the two missing teeth, which is a great indication for an Encore? bridge. These tooth replacements are not recommended for back teeth because they aren't strong enough and the bonding procedures become too difficult back further in the mouth.

The concept of the Encore? bridge is a variation of the Maryland bridge, which also bonds to the adjacent teeth, but uses a metal framework. The metal, which is placed on the back of the adjacent teeth, will darken those teeth slightly, and thus there is a problem with the esthetics of this type of bridge

下面这个年轻女孩的12缺失病例由Gary Radz完成。

第二个12，22缺失的病例由加州的Opus One Dental Lab制作。这个患者缺牙两侧牙齿完好，这是encore粘接桥最好的适应症。这种encore粘接修复体对于后牙不十分推荐，因为强度不够，而且粘接困难。

Encore桥的概念实际上是马里兰桥的变异。区别只是马里兰桥采用金属桥架。金属用于牙齿的舌侧，可以使得牙齿微变暗，所以马里兰桥的美观上稍有问题。

本病例采用了圆形桥体技术，使得桥体好像从牙龈中长出一样。
