“…The ceramic extension into the central cavity through the pulp chamber caused such a fracture type. Essentially, the preparation principles for endocrown restorations are unclear, and more clinically relevant research is needed for daily practice.…”

“… 2 During the recent years, PFM restorations have been increasingly used due to their high fracture resistance and esthetics. 3 One of the fundamental prerequisites of metal-ceramic systems is proper metal-ceramic bond strength that can provide suitable strength for the restoration. 4 Numerous studies have evaluated the bond strength between porcelain and noble and base metal alloys and different results have been reported.…”

PURPOSEConsidering the importance of metal-ceramic bond, the present study aimed to compare the bond strength of ceramics to cobalt-chrome (Co-Cr) alloys made by casting and selective laser melting (SLM).MATERIALS AND METHODSIn this in-vitro experimental study, two sample groups were prepared, with one group comprising of 10 Co-Cr metal frameworks fabricated by SLM method and the other of 10 Co-Cr metal frameworks fabricated by lost wax cast method with the dimensions of 0.5 × 3 × 25 mm (following ISO standard 9693). Porcelain with the thickness of 1.1 mm was applied on a 3 × 8-mm central rectangular area of each sample. Afterwards, bond strengths of the samples were assessed with a Universal Testing Machine. Statistical analysis was performed with Kolmogorov-Smirnov test and T-test.RESULTSBond strength in the conventionally cast group equaled 74.94 ± 16.06 MPa, while in SLM group, it equaled 69.02 ± 5.77 MPa. The difference was not statistically significant (P ≤ .05).CONCLUSIONThe results indicated that the bond strengths between ceramic and Co-Cr alloys made by casting and SLM methods were not statistically different.

“…However, the primary limitation faced in both of the present cases was in maintaining the thickness of the restorations, which becomes crucial during fabrication. Gupta et al .,[ 15 ] when comparing the fracture resistance of endodontically treated teeth restored with bonded partial coverage restorations and full-coverage crowns, concluded that teeth with a loss of functional cusp can be better treated with full-coverage restorations than with partial coverage ones. [ 14 ]…”

Restorative treatment in recent times has seen a paradigm shift due to minimally invasive adhesive dentistry. With advent of material science, bonding mechanisms, and superior isolation techniques, treatments based entirely on adhesion are effectively attainable. The choice between direct and indirect restorative technique, mainly in posterior areas, is still a challenge and involves biomechanical, anatomical, functional, esthetic, and economic considerations. The rationale of this case report is to demonstrate a revised cavity design based on morphological principles in terms of geometry (height of contour and cuspal inclines) and structure (dentinoenamel junction morphology) inspired from conventional preparation techniques.
