This paper is intended to contribute to the recognition and understanding of problems related to polymerization shrinkage.
Scientific publications of relevance with regard to this subject were critically reviewed.
The dimensional changes which develop during the curing of resin composites and glass polyalkenoate cements are studied, with special reference to methods of determining shrinkage, shrinkage stress and stress relief.
As no method for handling the adhesive restorative materials has yet been described which guarantees a leakproof restoration, the practitioner has to accept the problem of polymerization shrinkage and destructive shrinkage stress. Only a proper understanding of the mechanisms that cause these problems and the techniques that may reduce their effects will enable the practitioner to derive maximum benefit from the application of resin composites and glass polyalkenoate cements in restorative dentistry.
本文旨在促进对与聚合收缩相关问题的认识和理解。
对与此主题相关的科学出版物进行了严格审查。
研究了树脂复合材料和玻璃聚烯酸酯粘固剂固化过程中发生的尺寸变化，特别提及了确定收缩、收缩应力和应力释放的方法。
由于尚未描述出一种能确保修复体无渗漏的处理粘结修复材料的方法，从业者不得不接受聚合收缩和破坏性收缩应力的问题。只有正确理解导致这些问题的机制以及可能减轻其影响的技术，从业者才能从树脂复合材料和玻璃聚烯酸酯粘固剂在口腔修复学中的应用中获得最大益处。
