Effect of Corrosion on the High Cycle Fatigue Strength of Martensitic Stainless Steel X12CrNiMoV12-3 [PDF]

, 2012
This paper addresses the effects of corrosion on the high cycle fatigue (HCF) strength of a high mechanical strength martensitic stainless steel (X12CrNiMoV12-3) that is used in aeronautic applications. HCF tests (between 105 and 107 cycles) were carried

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

In vivo evaluation of the enamel wear of primary molar against four types of crowns using the intra-oral scanner

BMC Oral Health
Background Primary tooth wear is a common phenomenon that affects chewing ability, dental sensitivity, aesthetics, and occlusion. This study was conducted to compare the antagonistic enamel wear of primary molars opposed to four different crown materials.

Bond strength enhancement for additively manufactured zirconia: Micro‐retentive design approach

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effect of digitally designed micro‐retention features on the bond strength of additively manufactured (AM) zirconia copings. Materials and Methods Sixty titanium base abutments (NobelParallel, NobelBiocare), pretreated with 50 µm alumina particles were divided into four groups (n = 15 per group); one group with ...

Comparative evaluation of stress generation in primary teeth restored with zirconia and BioFlx crowns: A finite element analysis

Dental Journal
Background: Maintaining the functional integrity of primary teeth is important, as these teeth are integral in vital functions such as mastication, speech development, and space maintenance for permanent teeth; hence, premature loss of primary teeth can ...

Influence of occlusal thickness and aging on the fracture load of additively manufactured definitive crowns in different resins

Journal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to assess the effects of occlusal thickness and thermomechanical aging on the fracture load of additively manufactured (AM) definitive crowns made from resins with different compositions, compared with crowns subtractively manufactured (SM) from a polymer‐infiltrated ceramic network. Materials and
