CLINICAL PROTOCOLS: PREPARATION, IMPRESSION AND BONDING OF ALL-CERAMIC GLASS-BASED DISILICATE LITHIUM CROWNS: REVIEW AND CASE REPORT.

Using contemporary materials and techniques, nowadays we can offer the patients much needed restorations while achieving the desired aesthetics. The maxillary incisors are supremely important in the appearance of a smile. By establishing proper size, contours, vitality, translucency and relationship with the surrounding teeth and soft tissue, we can help create the smile of their dream. In modern dentistry, there are two major recent developments - the dentine bonding and stronger all-ceramic crown systems. Use of glass-based disilicate lithium ceramic crowns in combination with resin cements provides more desirable aesthetic solution than traditional porcelain-fused-to-metal (PFM) crowns. However, use of these materials is extremely technique sensitive. They require additional marginal precision of tooth preparation and bonding with resin cement. Consequently, protocols of tooth preparation and bonding are essential for long-term success. The presented article describes the preparation, impression and bonding guidelines aided by case presentation. According to the discussed protocols, dentists who take advantage of benefits of these contemporary materials and technologies will achieve more durable and reliable bonding with improved aesthetics.
