Abstract
含有消毒剂组分的印模材料。
Description
本发明涉及以水解胶体为基础的含消毒剂的印模材料，该水解胶体尤其是如藻酸盐之类的不可逆型料。
在牙科领域的镶嵌物、齿冠、齿桥和假牙的制作中，用印模材料制造上述诸件的阴模，然后注满模塑石膏，用该石膏模型（阳模）可以作出所需要的牙科制品。
最好用不可逆水解胶体作印模材料，在牙科制作方面，特别是用藻酸盐和琼脂作印模。
在牙科领域中，不可逆水解胶体的印模材料已长久地用来生产印模（美国专利23 45 255号），还已知在印模材料中采用琼脂（H.J.Rehberg，Die Quintessenz der zahnarztlichen Abformmittel（牙科印模剂的浓浸膏），Verlag“Die Quintessenz”Berlin 1971，pages18，57-61）。
水解胶体形成一种致病病菌的培养基，这些病菌如病毒、细菌、真菌和孢子。这存在相当大的危险性，即所述病菌由牙病患者通过印模传播和蔓延。
上述问题是已在的，在Dentalecho 1/87，51至54页（1987年）中已详细论述。该文指出还未找到水解胶体的适宜消毒剂，消毒作用在实际应用中应不会降低印模的精度。
Dentalecho 1/87，51至54页（1987）叙述了牙科实践中印模在缺乏卫生条件下消毒的另一难题。按该文的见解，牙科操作中感染的危险性通常被错误估计，这还涉及往往难以检查出处于危险的患者这一事实。
就一切情况而言，为保证断绝污染渠道，必需确保制成的印模经消灭致病病菌而消毒。
已知以戊二醇和酚盐缓冲水溶液为基础的活性化合物的组合物（美国专利4103001号，company publication on Sporicidin by Breitschmidt AG，CH 6020Kriens），并可用来消毒冷却的藻酸盐印模。根据该公司刊物，印模浸入1至16 Sporicidin水溶液短期消毒，不经漂洗而压实。
这种消毒方法有许多缺点，例如其消毒程度主要取决于印模浸入消毒水溶液的时间，浸入消毒溶液时期太短，使病菌不能完全杀灭。另一方面，浸渍时间太长，会使印模表面变形，对装配有影响。
此外，这种已知的印模消毒形式不保证在各种情况下能不间断地进行消毒。在制成印模后，总是不能确定是否仍需消毒。
现在已发现以水解胶体为基础的自身消毒印模材料，其特征在于其中含有消毒剂。
本发明的自身消毒印模材料确保能杀灭污染材料的致病病菌。印模因连续消毒产生配合精度的改变的情况已不可能产生。消毒进行是否已进行的不肯定情况也不再出现。本发明的自身消毒印模材料能保证断绝污染渠道。
另外，本发明印模材料不明显地表现出较高的贮藏稳定性，甚至长期贮藏后，仍将保持印模的高质量。
本发明优选消毒剂是苯酚衍生物和铵盐。
可列举的苯酚衍生物是下述化合物：甲酚、氯甲酚、二甲苯、氯二甲苯、异丙基甲酚、氯代百里酚、苯基苯酚和双酚。
可列举的铵盐是下式的化合物：
式中：
R1、R2、R3和R4是相同的或不同的，指的是甲基、乙基、丙基、丁基、戊基、己基、庚基、辛基、壬基、癸基、十一烷基、十二烷基、十四烷基、十六烷基、十八烷基或苄基，以及
X是氯或溴。
