Comparative Study between Two Adjacent Implants Supported Crowns and One Implant Supported Cantilever Fixed Dental Prosthesis: An Study.
J Contemp Dent Pract
October 2024
Department of Crown and Bridge, Faculty of Dentistry, Al-Azhar University, Cairo, Egypt.
Aim: To assess hard as well as soft peri-implant tissues within cases having two lost adjacent anterior teeth treated through placing either two implants with two separate crowns or only an implant along with a crown with a cantilever, and evaluating the effect of polyetheretherketone (PEEK) restoration on cantilever design up to 18 months after functional loading.
Materials And Methods: Twenty-seven participants (15 males and 12 females; mean age, 38.6 years; range 20-50 years) with missing two adjacent anterior teeth were treated with implant system (Flotecno implant system, Italy).
Carbon fibre reinforced polyetheretherketone (CFR-PEEK) implants have gained interest because of reported biomechanical advantages and radio-lucent properties. The aim of this study was to evaluate the role of CFR-PEEK nails in patients with metastatic bone disease (MBD). We performed a retrospective cohort study evaluating patients with MBD undergoing intramedullary (IM) nailing for prophylaxis or fixation of pathological fractures using CFR- PEEK or titanium implants.

Department of Orthodontics, Yenepoya Dental College, Yenepoya (Deemed to be University), Mangaluru, Karnataka, India.
Introduction: This study describes a novel device known as "SAVE" to effectively protract the deficient maxilla in class III malocclusion by quantifying and evaluating the changes in the maxilla through a finite element analysis (FEA).
Materials And Methods: The patented novel SAVE device was three-dimensionally modeled using Autodesk Fusion 360. An existing computed tomography (CT) scan of a patient exhibiting class III malocclusion was used to generate a finite element (FE) model.

A comparative analysis has been carried out between three different dental materials suitable for the prostheses manufacturing. The analysis performed is based on the finite elements method (FEM) and was made to evaluate their performance under three different loading conditions. Three different materials were modeled with 3D CAD geometry, all of them suitable to be simulated by means of a linear elastic model.

Polyetheretherketone (PEEK) is widely used in orthopedic and dental implants due to its excellent mechanical properties, chemical stability, and biocompatibility. However, its inherently bioinert nature makes it present weak osteogenic activity, which greatly restricts its clinical adoption. Herein, strontium (Sr) is incorporated onto the surface of PEEK using mussel-inspired polydopamine coating to improve its osteogenic activity.
