Dental Implants developed by IITD Researchers set for Commercialization

Giving an impetus to the “Make In India” campaign, researchers at IIT Delhi have designed and developed a dental implant system suitable for millions of smile that is all set to be commercialized by an industry partner.

The developed technology, which has successfully cleared animal and several clinical trials, was transferred to industry partner M/s Innvolution Healthcare Pvt. Ltd. for commercialization on a bigger scale as indigenous affordable healthcare solution with state of the art world class inbuilt quality, backed by continuous R&D innovation and evolving design variants.

The design of these implants started in 2007 at IITD under the Nationally Evolved Project (NEP) under the aegis of Council of Scientific and Industrial Research (CSIR) along with Maulana Azad Institute of Dental Sciences (MAIDS), Delhi. During the research process, there was a continuous monitoring of clinical feedback to improve the design of components, tolerances and surface morphology. The design of these dental implants was based on several parameters including - Indian anthropometry of the oral cavity, minimum inventory of implant system like a common abutment for various sizes of implants, enhanced osseointegration and cost effectiveness at the end even to a student dentist.

Elucidating on the implants, Prof Naresh Bhatnagar of Mechanical Engineering Department, IITD, who led this research for almost a decade said: “Edentulous (toothless) phenomenon can happen because of any reason like cavity, trauma, age or a disease. If not treated, the jawbone will start resorbing or remodeling due to no load leading to disfigurement of face and lower self-esteem. To overcome these symptoms, the only solution is to replace the lost tooth or the complete arch with a single or multiple root form of titanium based dental implant screws. The implant reverses any bone remodeling and helps one eat normally.”

The implant was designed for minimum stress generation during the insertion of a threaded Titanium self tapping screw into a human bone for better osseointegration by achieving a desired surface roughness and morphology on the macro and micro screw threads. A multi-function abutment reduces inventory for all the sizes of implant diameters varying from 3.2mm, to 5.0 mm for different lengths and with its development as integrated platform switching and as a single component which can serve as implant mount, implant impression, transfer coping and as the final straight abutment, the system reduces the overall cost of inventory.The research has accrued an Indian patent application, a PCT and is in the final stage of getting a US patent.

IITD manufacturing labs secured the license to manufacture medical devices by Drug Controller General of India (DCGI) and the Drug controller of NCT Delhi, for the purpose of examination, test or analysis. This is presumably the first time that an academic institute was granted a medical device-manufacturing license in the country.

A surgical kit containing all types of surgical drills and other surgical components like torque wrenches, paralleling pins, depth gauges, drill depth controllers as well as drivers of cover screw, healing screw, implant screw and implant drivers were also indigenously designed and developed under this project leading to design and fabrication of several precise components byoffering a complete solution of prosthetic and surgical needs as a real value for money.

It’s a matter of pride for IIT Delhi, CSIR NMITLI program and Maulana Azad Institute of Dental Sciences, Delhi to bring a well-researched medical device into the healthcare market of not only India but also the world.
