Comparative Evaluation of GBR Techniques Using Zirconia Barrier Membrane: An In-vivo Study | Chapter 5 | Medicine and Medical Research: New Perspectives Vol. 7

 

Aims: This study aims to evaluate the effects of customized zirconia barrier membranes produced for guided bone regeneration approaches on bone healing researched with histological and histomorphometric methods.

 

Study Design: In vivo experimental study.

 

Place and Duration of Study: The digital modeling and writing phase took place at Istanbul University Faculty of Dentistry, Department of Oral Implantology. The surgeries and sacrification procedures for the experimental animals were carried out in the operating rooms of the Surgery Department at the Faculty of Veterinary Medicine, Bursa Uludag University. The bone tissue samples obtained were histologically and histomorphometrically evaluated in the laboratories of the Pathology Department at the same university. The study started in August 2022 and ended in February 2024.

 

Methodology: The research involved using digital modeling to create zirconia barrier membranes suitable for a defect in the tibia bone. These membranes were designed using a 3D software system and transferred to the CAD/CAM software system in STL format. Zirconia discs (1400 Mpa) (Aconia BSM- D98x16, HT+, Germany) were then milled and sintered. The defects were covered using titanium mesh, titanium-reinforced d-PTFE, and zirconia barrier membranes, while one defect was left empty for the control group. At 3 and 6 weeks into the healing period, samples were obtained from each group after sacrificing the animals. Histomorphometric and histological analyses were conducted to evaluate new bone formation, the amount of remaining grafts, and tissue response parameters.

 

Results: The newly formed bone amounts of the zirconia barrier membrane, titanium membrane, and d-PTFE membrane groups were significantly higher than the control group in the 3rd and 6th weeks. The amount of residual graft progressed at a low level in both periods without any difference in the other groups except the control group. No foreign body reaction or necrosis was observed in any of the defects.

 

Conclusion: With the limitation of the study, it has been concluded that effective results can be obtained with zirconia barrier membranes in GBR procedures.

Titanium Toxicity and Allergy: Highlights on Titanium Structured Spectacle Frames | Chapter 8 | Research Highlights in Disease and Health Research Vol. 1

 Titanium has long happened the most valuable material used to forge dental implants and orthopaedic prosthetics cause it is thought of as an lifeless, incredibly resistant, and biocompatible mineral. However, titanium is not infaillible, as it has been liable to be subjected corrosion and to after titanium toxicity, hypersensitivity, and probably still to a form of autoimmunity. Evidence of failure of the device, though, is relatively unique. While commenting on its medical benefits and its disappointments, we discuss the rare use of the ingot in the spectacles manufacturing and some of allure exceptional, related snags. Due to its lifeless properties, to its being an intensely resistant and biocompatible ore, the titanium has won for age, a position as the most prominent material secondhand for the manufacture of dentures and orthopedic prosthetics.

Study on Conversion Treatment of Thin Titanium Layer Deposited onto Carbon Steel: Application of Physical and Mechanical Investigation | Chapter 13 | Newest Updates in Physical Science Research Vol. 14

In recent years, it has been possible to use small and/or microscale versions of more conventional mass spectrometers. As a result, small analytical instruments for 'in the field' sensing applications in aerospace, environmental monitoring, medical diagnostics, and process control have been created. This chapter examines the concepts that guide the creation of small quadrupole mass spectrometers. Two alternative microfabrication technologies are compared to a traditional QMS for residual gas analysis in the range of 1-100 Da. Two fabrication methods for small QMS realisation are described, as well as the fundamental concepts of QMS operation.

Studies on Different Techniques of Tympanoplasty: A Historical Review of Indian Perspectives| Chapter 11 | Highlights on Medicine and Medical Research Vol. 14

 Tympanoplasty surgery, which involves the reconstruction of the middle ear hearing apparatus, evolved from the basic eardrum repair methods known as myringoplasty. Tympanoplasty is the collective term for reconstructive surgery of the conductive hearing mechanism, which has gradually evolved over time with contributions from all over the world. The purpose of this historical review is to summarize Indian contributions to the development of the tympanoplasty technique. A review of the literature was conducted using only the “Medline” search engine with the keywords “tympanoplasty” and On June 15, 2016, “ossiculoplasty” was performed in “India.” A total of 195 articles and abstracts dating from 1998 to the present were discovered. Articles describing technique work were included, while those describing only graft material experimentation were excluded. All of the articles were thoroughly read and analyzed. It was discovered that there had been experiments regarding the selection of anaesthesia and the use of different chemical agents for this purpose. There were suggestions in favor of monitored anaesthesia care for select patients undergoing surgery. Surgeons shared their thoughts on the timing and conditions of surgery, laterality of surgery, different types of incisions, and the use of anesthesia. Endoscopes, graft placement techniques, ossicular replacements with autologous or allogenic grafts, and the timing of prophylactic antibiotic therapy administered after or during surgery are all discussed. The scope of the work is broad and covers the majority of surgical aspects; however, the incorporation of a consistent methodology and standards for reporting results was lacking in the articles reviewed. It is suggested that common guidelines for reporting tympanoplasty results be developed for the entire Indian subcontinent. Such an effort will promote uniform reporting standards, serving as a solid foundation for future analysis and research in middle ear reconstruction.

4-N-(7-Chloroquinolin-4-yl)-1-N,1-N-diethyl petane- 1,4-diamine Ti Complex: Synthesis and Characterization | Chapter 16 | Technological Innovation in Pharmaceutical Research Vol. 3

 Aims: Chloroquine is a member of the 4-aminoquinoline medication class that is used to prevent and cure malaria in locations where the disease is known to be susceptible to its effects. Metals can form covalent bonds with carbon in most cases, resulting in metal-organic complexes. Our goal is to synthesize the chloroquine–titanium complex and investigate how it coordinates. Department of Chemistry, Michael Okpara University of Agriculture, Umudike, 2019. Place and Duration of Study:

Methodology: The chloroquine Ti(II) complex was created by reacting chloroquine phosphate with titanium(IV) oxide. UV, IR, and 1H NMR spectroscopy were used to characterize the metal complex.
The complex's UV spectra revealed intra ligand charge transfer (ILCT), ligand to metal charge transfer (LMCT), and the d-d transition. The complex's IR spectra revealed the involvement of the amine and imine groups in collaboration with Ti. Chloroquine acted as a bidentate ligand as a result of this. The amine group's role in coordination was further demonstrated by 1H NMR of the spectrum.

Conclusion: Chloroquine's ability to sequester the Ti (II) ion has been demonstrated. This medication can remove Ti ions from a solution, the environment, or a biological system.

Surface Precipitation and Passivation on Ultrafine-Grained Titanium in Physiological Solution | Chapter 10 | Current Perspectives on Chemical Sciences Vol. 3

 This study is an attempt to understand how Ti substrate microstructures influence the change in chemical composition and the repassivation of the titanium surface immersed with bovine serum albumin applied in the simulated body fluid solution. As a goal, commercial pure titanium (CP-Ti) and Ti-0.2Pd were used. For the grain refining of both metals, equivalent channel angular pressing was done. To create different microstructures for comparison, some titanium specimens were subjected to heat-treatment. For the assessment of corrosion resistance and passivation activity, electrochemical impedance spectroscopy ( EIS) was measured. X-ray photoelectronic spectroscopy and scanning electron microscopy have studied the surface compositions and morphologies. The solution used in corrosion and immersion testing was pure simulated body fluid bubbled with N2. Corrosion test results showed a higher resistance of ECAP Ti-0.2Pd to corrosion than ECAP CP-Ti. Insignificant Warburg impedance suggested the formation of porous layers on ECAP titanium and thus easy layer transformation of ions and the corrosion product. The immersion test results showed that more precipitated particles were produced on ECAP metals than on metals that were heat treated. Enhanced precipitates formed on ECAP Ti-0.2Pd were established due to an improved Ti-0.2Pd hydrogen evolution reaction relative to ECAP CP-Ti. The rainfall consisted of C, N, O, Ti, Ca and P. The bioactivity improvement of the Ti implant is basically advantageous for more Ca, P, Ti and O contents in surface deposition on ultrafine grained Ti. This result offers a way to enhance the bio-bonding between the implant and the surrounding tissue.
