Bi-layered single-piece dental implant reduces the need for surgical interventions

New Delhi, Sep 8: Researchers have developed a bi-layered structure integrating titanium alloy and zirconia components for dental applications that enhances durability, interfacial stability, and biocompatibility while reducing surgical complexity.

Traditional dental implants consist of three components: a fixture embedded in the jawbone, an abutment connecting the fixture and crown, and the crown itself. These multi-component assemblies are susceptible to micromovements at the abutment interface, which can compromise osseointegration and lead to implant loosening.

Furthermore, such systems typically require two to three surgical procedures, increasing patient discomfort and clinical complexity. Although titanium alloys and zirconia are widely used due to their biocompatibility and mechanical strength, each material has inherent limitations. Ti6Al4V can be susceptible to corrosion and gum recession in the moist environment of the mouth, while zirconia, although aesthetically appealing and corrosion-resistant, may degrade over time due to hydrolysis, affecting its long-term stability.

To overcome these challenges, scientists at the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), an autonomous institute of the Department of Science and Technology (DST) have designed a functionally integrated bi-layered structure that integrates titanium alloy (Ti6Al4V) and yttria-stabilized zirconia (YSZ) into a unified structure to address persistent limitations of conventional implants.

In the structure, the Ti6Al4V serves as the load-bearing fixture for strong jawbone integration, and YSZ forms the crown region to provide superior wear resistance and aesthetics.

The implant was fabricated using Spark Plasma Sintering (SPS), an advanced powder metallurgy technique. A custom-designed tapered graphite die enabled precise temperature control during sintering, allowing simultaneous densification of Ti6Al4V and YSZ, despite their widely differing sintering temperatures.

This approach achieved a density of 99.5% in the material, producing a strong, defect-free bi-layered structure in a single processing step. After sintering, machining trials were conducted using a 5-axis CNC machine to produce the threaded implant shape. Some challenges related to tool movement along curved surfaces were observed, and process optimization is currently underway.

The overall fabrication approach remains highly reproducible and suitable for scaling up to industrial production.

Tests confirmed a distinct, well-bonded interface without cracks, delamination, pores, or secondary phases. Analysis revealed fine YSZ grains (~0.3 µm), while Ti6Al4V grains near the interface were refined to 0.3–1 µm compared to the bulk. No noticeable elemental diffusion was observed across the interface, indicating a stable ceramic–metal transition zone. The fabrication route demonstrates high reproducibility, making the process scalable for industrial production.

Mechanical evaluation of the dense, bi-layered structure showed hardness values up to 1350 HV, compressive strength of approximately 1550 MPa, and flexural strength of approximately 310 MPa, comparable to or exceeding those of commercial implant materials. In vitro biological studies confirmed non-cytotoxic behavior and excellent biocompatibility. MTT assays (colorimetric test used to measure cellular metabolic activity) using L929 mouse fibroblast cells showed metabolic activity exceeding 90% across all tested concentrations, surpassing the minimum threshold for biomaterials. Hemolysis tests indicated negligible red blood cell damage, validating suitability for dental applications.

By integrating mechanical robustness, corrosion resistance, aesthetic performance, and biological safety into a single-piece architecture, ARCI’s bi-layered implant reduces the need for surgical interventions while improving long-term stability and patient outcomes. The innovation aligns with India’s growing demand for affordable, high-performance dental implants and strengthens indigenous biomedical device development.

SKIMS Bemina issues show-cause notice to CRMIs over absence from duties

Srinagar, Sep 8: The authorities at SKIMS Medical College, Bemina, have issued show-cause notices to Clinical Resident Medical Interns (CRMIs) allegedly found absent from their duties for the past one week, stating that their absence has adversely affected patient care and emergency services at the hospital.

According to the notice, a copy of which lies with the news agency—Kashmir News Observer (KNO), the administration has taken serious note of the non-attendance of “most of the CRMIs” and termed the situation a matter of concern, particularly in view of the impact it could have on routine patient care as well as emergency services.

The notice said CRMIs had submitted affidavits at the time of joining, in which they had undertaken to remain disciplined and abide by the rules and regulations of the medical college.

The affidavits also contained an undertaking that the interns would not participate in strikes, court cases or any other activities considered acts of indiscipline,” it said.

It said the absence from duty is contrary to the undertakings given by the CRMIs at the time of their joining. “Such conduct could invite disciplinary action, including measures such as curtailment, temporary suspension or cancellation of internship, subject to the applicable rules and regulations”.

The administration has directed CRMIs who have not been attending their assigned duties to submit an explanation within 24 hours of issuance of the notice.

They have been asked to explain why appropriate disciplinary action under the rules should not be initiated against them.

The notice warns that failure to submit an explanation within the stipulated period would be presumed as having no defence or explanation to offer, following which the matter would be dealt with “strictly as per applicable rules.”

GMC Anantnag interns condemn show-cause notices to student representatives

Anantnag, Sep 08: MBBS Interns of the Government Medical College Anantnag “strongly” condemned the issuance of a show-cause notice to the two student representatives- Dr. Mohammad Akib Javid and Dr. Runga Zamin Javaid- in connection with the ongoing interns’ protest for their legitimate stipend demands.

In a statement, the MBBS interns said, “It is deeply concerning that, out of the entire group of protesting interns, the administration has chosen to issue the notice specifically to the two representatives who have been communicating the collective concerns of the interns.”

“We believe that raising genuine grievances and representing fellow students cannot be equated with gross indiscipline or professional misconduct,” it added.

The notice issued by the medical college warns of the possibility of curtailment, temporary suspension and even cancellation of internship.

Reacting to the move, the interns said that such a language is extremely intimidating and has created a sense of fear among interns who are simply demanding their legitimate rights.

They said that student representation is not misconduct and raising legitimate concerns is not an act of indiscipline. They urged authorities to engage with the representatives through dialogue rather than threatening them with punitive action.

“We remain respectful of the institution and the authorities, but respect must be mutual,” the statement said.

The internee students appealed to the administration and the concerned authorities to withdraw the notice and resolve the stipend issue through meaningful dialogue rather than coercion or intimidation.

“Our representatives will not be abandoned. We stand united, and our demand for justice, dignity and a fair stipend will continue peacefully and democratically,” the students said.

‘Naraz Fufa ji’ now has work, says Modi after inaugurating freight corridor

Vadodara, Sep 08: Prime Minister Narendra Modi on Tuesday slammed those who question his government’s development record, once again calling them as Naraz Fufa (angry uncle).

Speaking at the NaMo for Viksit Bharat programme in Gujarat’s Vadodara, where he inaugurated and laid the foundation stones for Rs 35,000 crore development projects, Modi said the country’s work culture has transformed over the last 12 years after the BJP came to power.

The projects include a 2,800-kilometre dedicated freight corridor, which Modi called a “historic achievement for the 21st century”.

Taking a swipe at those who would question the utility of the corridor project, Modi said, “One Naraz Fufa ji will say: What will the truck drivers do?” “Naraz Fufa now has work,” he said, without naming Congress leader Rahul Gandhi.

“After 2014, India built 50,000 modern rail coaches but the previous (Congress) regime could not build even 50,000 toilets in 10 years,” Modi said.

Modi inaugurated three key sections of the Western Dedicated Freight Corridor, connecting Jawaharlal Nehru Port in Navi Mumbai with Dadri in Uttar Pradesh, marking completion of the project.

“Dedicated freight corridors are the lifeline of a fast-developing India. India’s transformation is accelerating because of this modern freight network,” Modi said.

Earlier, passenger and goods trains had to run on the same tracks, slowing down both passenger travel and freight movement but the Dedicated Freight Corridor has changed this, he said.

“After 2014, with your blessings, when I reached Delhi, and as soon as we arrived there, we began accelerating this project. Work on the 2,800 km dedicated freight corridors has been completed today,” he said.

“Today, the Eastern and Western Freight Corridors are becoming the main backbone of the country’s trade and business,” Modi said.

The 2,800-km long Dedicated Freight Corridor a testament to how the country’s work culture has transformed over the past 12 years, Modi said.

“The idea for this Dedicated Freight Corridor began in 2004. In 2006, a special company was established to carry out this work, and until 2014, files just kept shuffling from one place to another.

“Unfortunately, even these files weren’t fortunate enough to get a dedicated corridor. The files would get stuck, hang around and wander aimlessly,” Modi said.

Modi took a swipe at Rahul Gandhi’s ‘Chhatron Ki Goonj’ initiative, saying youngsters would stand with the truth and not be misled by what he termed “Jhooth ki Goonj” (echo of lies).

“At every nook and corner, you will find people who will try to mislead you through ‘Jooth Ki Goonj’, but today’s youth will stand with the truth,” the PM said.

‘Chhatron Ki Goonj’ is a student-dialogue campaign launched by the Congress, under which programmes are being organised in various cities across the country.

Through the campaign, the Opposition party is attempting to corner the ruling BJP on issues such as exam question paper leaks, costly education, irregularities in government recruitment and unemployment.

The prime minister said the youth could see how focused the government was on working across sectors, including solar, wind, hydro and nuclear energy.

Modi also urged the youth to develop expertise in Artificial Intelligence (AI).

“The youth of the country have to become experts in AI, and we want our youth to excel in the field,” he added.

Modi flagged off freight train services from New Sanand, New Makarpura, New Umbergaon and New JNPT in Navi Mumbai. He also flagged off a passenger train service between Tanda Road and Vadodara.

Promote PM Package teachers, other employees: AMEAK

Promote PM Package teachers, other employees: AMEAK

In a press statement, AMEAK President RubonSaproo, as per a statement issued on Monday, said that nearly 70 percent of the employees appointed under the PM Package in 2010 were teachers, but unfortunately, they have not been granted any promotion to date despite having completed the requisite years of service.

He said MTS employees of the Revenue Department and Data Entry Operators in the Finance Department were also facing a similar issue where the MTS employees of the Finance Department had already undergone the DPC process but were awaiting the formal issuance of promotion orders.

He also pointed out that Government Order No. JK-34-DMRRR, issued in 2022, already provides a mechanism under which PM Package employees can be considered for promotion. The order envisages the framing of a parallel promotion list corresponding to the general cadre for granting promotions to package employees, however, their promotions should not be linked to promotions in the general cadre, as the PM Package is supernumerary and distinct in nature.

Appealing to the government to implement the provisions of the 2022 order in letter and spirit, Saproo said that despite the existence of a specific government order facilitating the promotion of package employees, teachers appointed under the package have remained deprived of this basic career benefit for years. “Nearly 80 percent of the package teachers appointed in 2010 are likely to retire within the next six to ten years and not granting them promotion is not only unjust but also defeats the very purpose of the provisions made for these employees,” he said.

He further stressed that MTS employees of the Revenue Department and Data Entry Operators of the Finance Department deserve fair treatment in matters of promotion. He called for the immediate issuance of formal promotion orders in favour of the MTS employees of the Finance Department, who have already completed the DPC process.

“These employees have rendered more than a decade of service under extremely difficult circumstances and keeping them stagnated at the same level since their appointment is neither fair nor consistent with the spirit of the government order,” Saproo said.

Doctors’ issue genuine, needs early resolution, says Tanvir Sadiq

Srinagar, Sep 08: National Conference leader Tanvir Sadiq on Monday backed the protesting doctors in Jammu and Kashmir, saying their concerns were genuine and should be resolved at the earliest while condemning any threats issued against them.

Sadiq said Chief Minister Omar Abdullah had acknowledged the issue and that Health Minister Sakina Itoo was personally looking into it.

“Omar Sahib said yesterday that this is certainly a genuine issue and that it needs to be resolved at the earliest,” Sadiq said. “That is why our honourable Minister, Sakina Ji, is personally looking into it. Inshallah, we hope that a resolution will be reached as soon as possible.”

Asked about reports that protesting doctors had received threats, Sadiq strongly condemned any such threats and defended their right to demonstrate.

“If there are threats, that is very wrong. They are our children; they are the sons and daughters of the soil,” he said.

Sadiq added that protesting was a legitimate democratic right as long as it was conducted peacefully.

“They have every right to protest. We have always said that everyone has the right to protest in a democratic manner, and they have that right too,” he said, adding that efforts would continue to address their concerns.

His remarks came ahead of the upcoming Assembly session, where the doctors’ issue is expected to be among the matters raised by members.

On the Opposition’s likely strategy in the Assembly, Sadiq said the BJP had every right to question the government but should focus on issues concerning the people.

“They do that; it is the job of the Opposition. We have no problem if they raise issues,” he said. “One thing we need to understand is that questions concerning the people are raised in the Assembly, bills are introduced and resolutions are brought.”

“The Assembly is an important platform where we can speak about the concerns of the people,” he said, urging the Opposition to use the House to raise public issues.

“My advice would be that the Opposition should allow the issues of the people to be discussed in the Assembly and should put forward its own views. They have a right to do so, and they should certainly exercise that right,” Sadiq said.

Sadiq was also asked about the legacy of National Conference founder Sheikh Abdullah, and said his contribution to Jammu and Kashmir could not be adequately described.

“Whatever we say in praise of Sher-e-Kashmir’s contribution to every sphere of Jammu and Kashmir and to the country is not enough,” he said, citing his contributions to education, healthcare and social reform.

He particularly referred to Sheikh Abdullah’s land reforms, saying that the “land to the tiller” policy transformed the lives of people by giving them ownership of the land they cultivated.

Sadiq also credited Sheikh Abdullah with laying the foundations that enabled generations of students from Jammu and Kashmir to pursue education across India and abroad, and highlighted his contribution to women’s representation and the development of educational and agricultural institutions in the region.

Houthi attacks on Saudi Arabia wound 73 people, officials say

Cairo, Sep 08: More than 70 people were wounded in a wave of Houthi attacks Tuesday on Saudi Arabia, authorities said, a major escalation in the renewed conflict between an important US ally and the Iranian-backed rebels in Yemen.

The attacks come after weeks of escalating clashes between the Houthis and Saudi-backed government forces in Yemen, which shattered a four-year truce in the country’s civil war.

Fighting has raged on fronts including Yemen’s west coast, with government forces saying they have made territorial gains in the provinces of Hodeida, Taiz and Baydah. The Houthi have also launched attacks on Saudi oil facilities and tankers in the Red Sea.

The attacks early Tuesday hit “civilian and economic facilities” in the Saudi cities of Abha’s Jazan, Najran and Khamis Mushait said Maj Gen. Turki al-Malki, a spokesperson for the Saudi-led coalition fighting in Yemen, said in a statement.

Al-Malki said the attacks wounded 73 people, including women and children. He didn’t provide a breakdown or further details.

He called the attacks a “serious escalation” and a “flagrant violation of the kingdom’s sovereignty, and a direct threat to the security and safety of its citizens and residents”.

Al-Malki vowed retaliation, saying that the Saudi-led coalition “will take all necessary operational measures to deter the terrorist Houthi militia with utmost resolve”.

The Houthis did not comment on the attacks, but said a statement about “a large-scale military operation” deep inside Saudi Arabia would be released.

Nasruddin Amer, deputy head of the Houthi media office overseeing the Saba news agency run by the rebels, took to social media to laud the attacks.

“The Saudi enemy has to understand that the time for committing crimes and massacres against the Yemeni people without response, deterrence, or paying a price has ended,” he said.

The attacks came hours after the rebels blamed Saudi Arabia for an airstrike that hit a prison in Yemen’s northern province of Jawf. At least seven people, including a child, were killed and seven others were wounded in the strike in the city of Hazem, the Houthis said

Yemen’s civil war began in 2014 when the Houthis seized the capital, Sanaa, and much of northern Yemen and forced the government into exile.

A Saudi-led coalition, including the United Arab Emirates, intervened the following year to try to restore the government to power.

Tensions rose earlier this year between US allies Saudi Arabia and the UAE as their partnership in the war in Yemen broke down, leading to the UAE pulling out of Yemen.

The civil war in Yemen has killed at least 150,000 people, according to UN estimates, and at times pushed the country to the brink of famine.
