Clinical evaluation of a new pressed glass ceramic inlay material over 1.5 years.

Ten IPS/Empress pressed glass ceramic inlays were cemented in box-shaped, non-beveled, Class II, posterior cavities. They were evaluated clinically according to modified US Public Health Service criteria after 1.5 years in vivo. In addition, quantitative marginal analysis was performed immediately after placement of the inlays and at the 1.5-year recall. Clinical evaluation revealed that the inlays performed well after 1.5 years; all inlays received scores of Alfa or Beta for all criteria evaluated. Scanning electron microscopic examination indicated that the excellent initial marginal adaptation decreased significantly over 1.5 years.

[P-30: in vivo study of a posterior composite during 2.5 years].

P-30, a light-cured radioopaque hybrid composite was developed as a successor to the well known chemically cured P-10 for use as posterior composite. With the help of a computerized measuring method the occlusal wear of occlusally loaded conventional P-30 MOD restorations was analyzed after 6, 12, 18 and 30 months of clinical service. Simultaneously the wear patterns in occlusal contact areas and in contact-free areas were evaluated using the SEM. In addition, marginal adaptation immediately after the placement of the restorations and at all recall intervals was quantitated in the SEM. The long-term results indicated that P-30 was not suitable for use in unetched conventional posterior cavities.
