Abstract:

BACKGROUND: High strength, good aptness, and acceptable aesthetic effect are all necessary for fixed partial denture (FPD). The specific choice of materials should be based on the site of tooth defects, scope and have or not carious organizations. Therefore, which kind of materials has good performance and biocompatibility?
OBJECTIVE: To summarize the biocompatibility of different dental materials from the aspect of hylology and clinical application, and to evaluate the clinical effect of radiopaque glass Ionomer luting cement, silver amalgam, light-cured composite filling materials on the interproximal caries of permanent molars.
METHODS: The articles from January 2000 to October 2010 was retrieved, with the key words of “dental rehabilitation, materials, ceramics, alloy, compatibility” in Chinese, and “interproximal caries, permanent molar, filling” in English. The articles related to the application and compatibility of different materials on mouth rehabilitation were included, duplicate and Meta-analysis documents were excluded. It is better to cite mainly the 25 literatures and to discuss the importance of the properties of different dental materials.
RESULTS AND CONCLUSION: The traditional alloy restorative material commonly has the disadvantages of high hardness, wear resistance, but which relies on mechanical retention, and has obvious repair hole edge micro-leakage, must be strictly prepare cavity. However, ceramic and pulvis has adhesion, low hardness, and poor marginal microleakage. With the emergence and rapid development of nano-materials and technology, dental materials combined with nano-materials technology, a new idea and material technology model were formed in the introduction of modification and innovation, it will achieved breakthrough in the field of stomatology.
