Preliminary fabrication and characterization of electron beam melted Ti–6Al–4V customized dental implant

Abstract

The current study was aimed to fabricate customized root form dental implant using additive manufacturing technique for the replacement of missing teeth. The root form dental implant was designed using Geomagic™ and Magics™, the designed implant was directly manufactured by layering technique using ARCAM A2™ electron beam melting system by employing medical grade Ti-6Al-4V alloy powder. Furthermore, the fabricated implant was characterized in terms of certain clinically important parameters such as surface microstructure, surface topography, chemical purity and internal porosity. Results confirmed that, fabrication of customized dental implants using additive rapid manufacturing technology offers an attractive method to produce extremely pure form of customized titanium dental implants, the rough and porous surface texture obtained is expected to provide better initial implant stabilization and superior osseointegration.

Effect of disinfection and sterilization on the tensile strength, surface roughness, and wettability of elastomers

“…The images were captured at a 3× optical zoom. The data obtained by scanning the surface provided various parameters of the surface, and the integrated software, Vision64, translated the data into a 3‐D image . Several areal surface texture parameters, such surface roughness, the maximum surface peak height, the maximum valley or pit depth, the sum of the largest peak height value and largest pit or valley depth, the root mean square value of the sampling area, the measure of skewness or symmetry in roughness, and kurtosis of topography height distribution/the spread of height distribution were recorded.…”

“…The dynamic contact angle measurements were taken for the duration of 18 s from the time of initial contact of the water droplet. The images were captured using a built‐in digital camera …”

“…The images were captured using a built-in digital camera. 17,18 The values were then tabulated and subjected to two-way analysis of variance. All statistical analyses were done with SPSS 17.0 (SPSS, Chicago, IL, USA).…”

Selective laser melted titanium implants play a positive role in early osseointegration in type 2 diabetes mellitus rats

“…Over the last two decades, dental implant has become an ideal treatment modality for edentulous patients 1) . Titanium and its alloys are the most widely used implant materials for their excellent mechanical strength, chemical inertness and high biocompatibility properties 2,3) . With the growing implantation demand of type 2 diabetes mellitus (T2DM) patients, an ongoing problem is that the higher failure rate of implant surgery in type 2 T2DM patients because its poor bone formation and the consequent osseointegration problems 4) .…”

Porosity detection in electron beam-melted Ti-6Al-4V using high-resolution neutron imaging and grating-based interferometry

“…Ti-6Al-4V additive manufacturing (AM) has played a key role in modern scientific exploration, from biocompatibility studies with mouse fibroblast cells [1] to dental implants [2]. As the role of AM grows larger, so does the need for understanding the effects of printing methods on materials.…”
