Clinical challenges and the relevance of materials testing for posterior composite restorations.

摘要: Posterior composite restorations have been in use for approximately 30 years. The early experiences with this treatment indicated there were more clinical challenges and higher failure rates than amalgam restorations. Since the days of posterior composites, many improvements materials, techniques, instruments placing these occurred. This paper reviews what is known regarding current primary method collecting performance data. review categorizes as those related to restorative dentist, patient. relevance laboratory tests discussed from perspective solving remaining materials screening new materials. problems are no longer serious challenges.
