A 4-year follow-up of rehabilitation of atrophied edentulous mandible with implant-supported overdenture

Journal of Oral Research and Review, 2015
Conventional complete dentures primarily rely on residual alveolar ridge and mucosa for support and retention. Patients with poor mandibular ridge foundation usually suffer from inadequate denture retention and stability. In such cases, implant-supported

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Comparative Analysis of Retention in Different Attachment Systems for Implant-Supported Overdentures

Journal of Pharmacy and Bioallied Sciences
Background: Implant-retained overdentures have become a popular choice in prosthodontics, providing enhanced stability and comfort for edentulous patients. The retention and stability of these overdentures largely depend on the attachment system used.

In Vitro Comparison of the Retentive Properties of Ball and Locator Attachments for Implant Overdentures

The International Journal of Oral & Maxillofacial Implants, 2014
To compare the retentive properties of ball and locator attachments during 5,000 insertion-separation cycles, corresponding to approximately 4.5 years of clinical use.Four dental implants (diameter, 3.8 mm; length, 12 mm) were inserted into the prepared beds of two polyethylene blocks.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Concentration of the distance between points in the unit ball [PDF]

, 1998
We prove that in every finite dimensional normed space, for “most” pairs (x, y) of points in the unit ball, ║x − y║ is more than √2(1 − ε). As a consequence, we obtain a result proved by Bourgain, using QS-decomposition, that guarantees an exponentially ...

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Finite Element Study of Three Different Treatment Designs of a Mandibular Three Implant-Retained Overdenture

Latin American Journal of Solids and Structures
This study compares ball, bar-clip and bar-ball attachment systems for implant-retained mandibular overdentures with three implants. The first implant is placed in the middle of the mandible and the other two are imbedded in the first premolar regions ...
