INTRODUCTION: Degenerative lumbar spine surgery is increasingly common, but osteoporosis and the need for long-segment fixation negatively impact implant stability. In our study, we investigated the effect of osteoporosi...

Background: Distal femoral megaprosthetic reconstruction is a standard limb-salvage procedure after tumor resection. This study aimed to evaluate implant survival and associated factors, the incidence of mechanical failu...

The enzyme heme oxygenase-1 (HO-1) is pivotal in reproductive processes, particularly in placental and vascular development. This study investigated the role of HO-1 and its byproduct, carbon monoxide (CO), in trophoblas...

Ultrathin ohmic contacts were fabricated on GaP(111) single crystals using argon ion (Ar⁺) implantation at an energy of E₀ = 2 keV and a dose of D = 2 × 10¹⁷ cm⁻², under high vacuum conditions (10⁻⁷ Pa). P...

BackgroundArtificial intelligence (AI) has substantial potential to advance periodontal and peri- implant care through novel diagnostic, prognostic, and therapeutic opportunities. Nevertheless, the evidence is scattered ...

Abstract Background Alzheimer’s disease (AD) is a growing global health concern, and emerging evidence suggests that oral health—particularly tooth loss—may be linked to cognitive decline. While implant therapy eff...

Background: Connecting an osseointegrated implant and a natural tooth is a treatment alternative for partially edentulous patients in some clinical situations. The main issue of a connected tooth-implant system is derive...

Abstract Accurate specimen preparation is essential for biomechanical push-out testing of bone–implant interfaces. A common source of error arises when implants such as pins or screws are not cut exactly perpendicular ...

Abstract Background Immediate implant placement (IIP) requires sufficient primary stability to permit implant-supported immediate provisionalization, which supports peri-implant soft tissue contour during healing, partic...

Abstract Objective To compare outcomes in patients with repeated implantation failure undergoing Intracytoplasmic Sperm Injection/In vitro fertilization (IVF/ICSI) plus immunosuppressants such as prednisolone, predniso...

Abstract Objective To compare the peri-implant mucosal stability between an “open healing” approach (test) during immediate dental implant placement with bone grafting and immediate transmucosal provisionalization (n...

Abstract Purpose In dentistry, digital technologies have become firmly established in the field of oral implantology. The trueness of impressions taken using intraoral scanners as part of the digital workflow has a direc...

Abstract Objective To investigate whether patients with a previous recombinant follicle stimulating hormone (rFSH)-stimulated cycle would have improved outcomes with rFSH + recombinant luteinizing hormone (rLH) stimula...

Abstract Hypohidrotic ectodermal dysplasia (HED), caused by mutations in genes such as EDAR, is a genetic disorder characterized by hypodontia, hypotrichosis, and hypohidrosis. Dental anomalies in HED patients lead to fu...

ABSTRACT Healthcare systems are progressively shifting toward long‐term, personalized models that rely on continuous physiological monitoring, thereby intensifying the need for advanced bioelectronic technologies. The ...

Abstract Background Proper and consistent hearing aid (HA) fitting before cochlear implant (CI) surgery provides auditory stimulation with preservation of central auditory pathway activation that supports the post-implan...

Insufficient width of the alveolar ridge often prevents ideal implant placement. Guided bone regeneration, bone grafting, alveolar ridge splitting and combinations of these techniques are used for the lateral augmentatio...

Abstract Background Various designs of dental implants made of zirconium dioxide (zirconia) as an alternative to titanium implants are available as one-piece implant (OPI) or as bone-level or tissue-level two-piece impla...

Abstract Background This is the first systematic review and meta-analysis aimed at assessing the current status of robotic-assisted implant surgery (r-CAIS) in zygomatic implant (ZI) placement, with a particular focus on...

Background/Aim: The aim of this study is to examine with finite element analysis the distal bar extension, the bar substructure material type and the amount of bar substructure-abutment mismatch, and the stress caused by...

O presente artigo faz uma recuperação histórica, partir da cobertura jornalística realizada pelo Diário de S. Paulo – jornal da cadeia dos “Diários Associados” de Assis Chateaubriand –, sobre a implantaçã...

BackgroundPhakic intraocular lenses (pIOLs), used to correct high refractive errors, have since been associated with long-term complications including glaucoma and cataract formation. Elevated intraocular pressure (IOP) ...

Abstract Background Postoperative complications in patients with acute type A aortic dissection (ATAAD) significantly affect their prognosis. This study investigates the association between cardiopulmonary bypass(CPB) we...
