Distal Cantilever Length Comparison In Esthetic Material For Hybrid Implant Prosthesis: An In Vitro Study., Sana Shams Eddin, Elie Jasser, Mohammad Chams Eddin, Carole Abi Ghosn Yared, Joseph Makzoumi, Paul Boulos

International Arab Journal of Dentistry

Objective: the assessment of distal cantilever length in implant supported infrastructure by comparing the load to fracture in two different framework esthetic materials (Zirconia and Polyetheretherketone (PEEK)) with two different cantilevers loading distances (10mm, 15mm). Material and methods: 20 frameworks were fabricated and divided into 4 groups (n=5): according to the material type Peek, zirconia, and according to the cantilever loading distance (10), or (15) mm and a load-to-fracture test was used until complete fracture of specimens occurs. Results: The effect of material type and cantilever loading distance were statistically significant for the mean load-to-fracture values (P< 0.05). The Zirconia group failed at higher fracture loads (817 N) than the Peek one (651 N). Frameworks with 10 mm cantilever loading distance failed at higher fracture loads than specimens with 15 mm. Conclusion: Peek is a suitable material for all-on-four framework reconstruction in specific situations, and there is a higher success rate when the distal cantilever length is kept at minimal value (10mm).

An Update Of Additive Manufacturing (3d Printing) Technology In Dentistry., Rami Saleh Al Fodeh, Ahed Al-Wahadni, Baker Otman, Mahmoud Almasri

International Arab Journal of Dentistry

Background:

The development of procedures known as additive manufacturing, which aim to produce more complex items with a lower overall material consumption compared to processes known as subtractive manufacturing. In addition, in recent years there has been a significant rise in the quantity of dental materials that are produced via the use of these techniques. As a consequence of this, scientific research has been concentrating more and more on such technologies, particularly in order to shed light on the methodology, indicators, and boundaries of the emerging technology.

Methods:

The purpose of this paper is to provide a narrative assessment of …

Aloe Vera In Dentistry: Current Status And Future Prospects, Ashraf M. Abu-Seida, Heba Seif

International Arab Journal of Dentistry

This review declares the chemical composition, pharmacological actions, clinical applications, adverse reactions and future prospects of Aloe vera (AV) in the field of dentistry. Literature pertinent to Aloe vera in dental practice was explored in databases like PubMed, Scopus and Google Scholar. The relevant literature was reviewed and critically appraised in this review. Aloe vera is a miracle plant that has been applied as herbal therapy for thousands of years due to its multiple health benefits. In dental practice, AV has different applications and it attracts the attention of researchers due to its natural origin, low cytotoxicity, and various biological …

Rehabilitation Of A Patient With Single Complete Tooth Supported Overdenture Against The Unmodified Natural Dentition Using Functionally Generated Path Technique- A Case Report, Dr.Akanksha Shinde, Dr.Nilesh Bulbule, Dr.Varun Bhatt, Dr.Gayathri B, Dr.Amit Jagtap

International Arab Journal of Dentistry

Meyer’s proposed chew-in technique also called functionally generated path (FGP) technique, is indicated for the restoration of an edentulous arch that is opposed by natural teeth as it does seem to provide the most accurate method of recording occlusal patterns, also help to minimize the effects of negative factors, and to overcome the deficiencies of articulators [1]. As stated by Rudd and Morrow, this technique is especially suitable for tooth-supported complete dentures, due to inherent stability of tooth-supported record bases helps in recording jaw relationships accurately.

Whenever a single complete denture is opposed by natural dentition, problems observed are abrasion …

Influence Of The Margin Design On The Fracture Resistance Of Implant Supported Monolithic Zirconia Crowns, Camille Haddad, Ryan Harouny, Karim Corbani, Lara Nasr, Ronn Tassidis

International Arab Journal of Dentistry

The purpose of this in vitro study was to test the influence of the margin design of implant supported monolithic zirconia crowns and test if monolithic zirconia crowns with extra fine finish line thickness cemented on zirconia implant abutments can bare the maximum masticatory forces on molars and hence be used in the posterior region. Fourteen identical monolithic zirconia crowns cemented on zirconia implant abutments mounted on titanium bases and fixed on implant replicas embedded in PMMA resin were divided into two groups: group I designed with a 0.5 mm CFL (CFL) and group II with a feather-edge finish line …

Bioactivity And Ph Of Nano-White Mta Versus Neomtatm Plus® And Mta Angelus® As Root Repair Materials: An In Vitro Study, Rana A. Elkhashab, Abeer Mahran, Mahmoud Mohamed Badr, Ashraf M. Abu-Seida

International Arab Journal of Dentistry

Objective: This study compared the bioactivity and pH of Nano-white mineral trioxide aggregate (NWMTA), Neo-mineral trioxide aggregate plus (NeoMTA Plus), and Mineral trioxide aggregate angelus (MTA-A) as root repair materials.

Methods: A total of 60 discs made from the three materials (20 discs each) were prepared according to the manufacturer’s instructions. These discs were packed into plastic molds and allowed to set before testing. For bioactivity study, ten discs of each material were immersed in Hanks' Balanced Salt Solution (HBSS) for 28 days, and analyzed with scanning electron microscope with energy dispersive X-ray (SEM/EDX). Ten discs of each material were …

The Effect Of Bevel On Fracture Resistance Of Gic Restorations In Primary Molars: In Vitro Study Rôle Du Biseau Dans La Résistance À La Fracture Des Restaurations Aux Ciments Verres-Ionomères Des Molaires Temporaires : Étude In Vitro, Audrey Fikani Dds, Lara Nasr Dds, Ms, Mph, Elie Khoury Dds, Msc, Phd, Associate Professor, Marianne Freiha Md, Marc Krikor Kaloustian Dds, Msc, Phd, Clinical Professor, Fériale Abi Zeid Daou, Melissa Chaaya Dds, Marlene Khoury Dds, Msc, Phd, Associate Professor

International Arab Journal of Dentistry

Background: Glass ionomer cements (GICs) are commonly used for restorations in primary molars due to their adhesive, hydrophilic, and bioactive properties. However, their low mechanical resistance may limit their use in proximal cavities. Recent advancements in GICs, such as the high viscosity GIC EQUIA Forte®, have improved their mechanical properties. The effect of a Cavo superficial bevel on the mechanical strength of GIC restorations has been previously studied.

Objectives: To investigate the effect of a Cavo superficial bevel on fracture resistance and the type of fracture (adhesive, cohesive, or catastrophic) in EQUIA Forte® GIC restorations in primary molars.

Methods: 56 …
