“…Cerec 3 restorations exhibit a luting space, which is less than 100 µm [26,64]. This might have led to a reduction of the polymerization shrinkage, especially in the groups with a conventional preparation including angles of approximately α = 6°.…”

OBJECTIVES: This study aims to evaluate the effect of a minimally invasive mesial-occlusaldistal (mod) preparation on the marginal adaptation of ceramic and composite inlays with the aim of saving sound dental substance. MATERIALS AND METHODS: Class II mod cavities were prepared in 50 extracted human molars and randomly allocated to five groups (n = 10). In all groups, the mesialproximal box margins were located in the dentin, 1 mm below the cementoenamel junction (CEJ), while the distal box margins were 1 mm above the CEJ. In groups A and B, conventional standard preparations with a divergent angle of = 6°were prepared. In groups C, D, and E, minimally invasive standard preparations with a convergent angle of = 10°were prepared. In groups A and D, composite inlays and, in groups B and C, ceramic inlays were fabricated (chairside economical restoration of esthetic ceramics (CEREC)) and adhesively inserted. In group E, a direct composite filling using the incremental technique was placed. Replicas were taken before and after thermomechanical loading (1,200,000 cycles, 50/5°C, max. load 49 N). Marginal integrity (tooth-luting composite, luting composite-inlay) was evaluated by scanning electron microscopy (×200). The percentage of continuous margins in the different locations was compared between and within groups before and after cycling, using ANOVA and Scheffé post hoc test. RESULTS: After the thermomechanical loading, no significant differences were observed between the different groups with respect to the interface of luting composite-inlay. At the interface of toothluting composite for preparations involving the dentin, groups A and B behaved significantly better compared to the control group E, which in turn were not different to groups C and D. CONCLUSION: Composite and ceramic inlays inserted in minimally invasive prepared mod cavities result in margins not different from those of inlays placed in conventional mod preparations. Direct composite filling margins, however, were inferior to those attained by conventional indirect restorations. CLINICAL RELEVANCE: Minimally invasive preparations for mod inlays with undercuts show marginal adaptation equal to that of conventional inlay preparation design.

Marginal adaptation of different types of all-ceramic partial coverage restorations after exposure to an artificial mouth

Objectives To determine the influence of the preparation design and the dimensions of all-ceramic partial coverage restorations (PCR) on the marginal accuracy before and after masticatory simulation. Methods In this in vitro study 80 extracted human maxillary molars were restored with MOD inlay restorations and four different modified PCR restorations using a new press ceramic IPS e.max ® Press (IPS e.max ® Press VP 1989). The teeth were divided into five groups of 16 specimens each and prepared as follows: Group A received an MOD inlay preparation and Group B, C, D and E received modified PCR. The restorations were adhesively luted and exposed to a mastication simulator. The discrepancies of the marginal fit were examined on epoxy replicas before and after luting as well as after masticatory simulation at

“…5 Numerous studies have evaluated the clinical success of computerassisted fabrication methods and in particular the marginal accuracy of these restorations, showing promising results. [6][7][8][9][10][11][12][13] Recently a new resin composite block (Paradigm MZ100, 3M ESPE Dental Products) has been introduced for the CEREC system, which according to the manufacturers combines some of the best attributes of ceramics and polymers. 14 For ceramic restorations, a shoulder or broad chamfer preparation is recommended, but for resin composite less invasive chamfer and bevel preparations have been used extensively for direct cavity designs.…”
