摘要： A method for forming removable dentures using injection molding techniques wherein a cyanoacrylate base material is applied to the sides of the denture teeth, an activator or accelerator compound being sprayed onto the deposited base material whereby the base material is rapidly cured. The denture is then placed in the lower half of a mold, or flask, and a plurality of sprues are positioned therein. The upper flask portion is then attached to the lower half and the assembled flask is then invested with plaster material. The activated gel enables the teeth to be retained in position in the lower half of the flask. The flask is then placed in hot or boiling water and then deflasked to remove the melted wax. The flask is then reassembled and polymer injected therein filling the areas previously occupied by the wax. After the polymer is cured, the prothesis is removed, polished and then returned to the dentist.
摘要翻译：一种使用注射成型技术形成可移除假牙的方法，其中将氰基丙烯酸酯基材施加到义齿的侧面，将活化剂或促进剂化合物喷涂到沉积的基材上，由此基材迅速固化。然后将义齿放置在模具或烧瓶的下半部中，并且多个浇口位于其中。然后将上烧瓶部分附接到下半部分，然后将组装的烧瓶投入石膏材料。活化的凝胶使得齿可以保持在烧瓶下半部分的适当位置。然后将烧瓶置于热水或沸水中，然后将其放气以除去熔融的蜡。然后重新组装烧瓶，并在其中注入聚合物，填充先前被蜡占据的区域。聚合物固化后，取出假体，抛光，然后返回牙医。

摘要： A method of replacing a lost denture includes the steps of forming a mold 20 as an impression of the original denture, and of fabricating a replacement denture using this mold. The mold consists of a tissue side mold section and an exterior side mold section. The tissue side mold section is made of a dimensionally stable material, such as dental stone or an addition-cured silicone rubber, so that the tissue side of the denture can be accurately reproduced at a later time. The exterior side mold is made of a resilient material, so that the original denture and its duplicate can be removed from the mold. An injection passage and overflow passages can be drilled into the exterior side mold section so that a liquid resin can be injected to adequately fill the mold cavity to form the gum portion of the duplicate denture.
摘要翻译：更换失蜡的方法包括以下步骤：将模具20形成为原始假牙的印模，以及使用该模具制造替换的义齿。模具由组织侧模具部分和外侧模具部分组成。组织侧模具部由诸如牙科石或加固固化硅橡胶的尺寸稳定的材料制成，使得义齿的组织侧可以在稍后的时间被精确地再现。外侧模具由弹性材料制成，使得原始义齿及其副本可以从模具中移除。喷射通道和溢流通道可以钻到外侧模具部分中，使得可以注射液体树脂以充分填充模腔以形成重复义齿的牙龈部分。

摘要： A method for preparing dental restoration which is to be secured in the mouth of a dental patient includes providing a base plate with ready made x-ray opaque restorative teeth thereon, the base plate being formed in correspondence with the mouth of the patient in which the restorative teeth are to be fixedly secured. The base plate is temporarily situated in the patient's mouth and then the temporarily situated position of the base plate in the patient's mouth is observed, preferably via an x-ray. The temporarily situated position of the base plate in the patient's mouth is assessed to determine predetermined locations at which drill holes for facilitating the fixed securement of the restorative teeth in the patient's mouth are to bored.

摘要： Dental implant component (1; 1′) for a dental prosthesis or a core part of a dental prosthesis to be fabricated on comprising a base section (3; 3′) having a proximal end (2; 2′) for engagement with a support end of a support component and a distal end (7; 7′); and an elongate post section (5; 5′) which projects distally from the distal end of the base section and has a transverse dimension which is substantially less than the transverse dimension of the base section. In a first aspect of the invention the dental implant component is made at least in part from a material which is adapted to burn-out during lost-wax casting whereby a dental prosthesis or core part of a dental prosthesis fabricated on the dental implant component by lost wax casting includes at most only a part of the dental implant component. In a second aspect of the invention the elongate post section is positioned offset on the distal end of the base section.
