MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202541124032 A) filed by Saveetha Institute Of Medical And Technical Sciences, Chennai, Tamil Nadu, on Dec. 9, 2025, for 'sk surgical burs for impaction.'
Inventor(s) include P. Sai Krishna; B. Raj Prakash; and Deepak Nallaswamy Veeraiyan.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The invention of colour-coded SK burs addresses the limitations of conventional burs in oral and maxillofacial surgeries, specifically in procedures like the surgical extraction of impacted teeth, miniplate fixation for trauma, and orthognathic surgeries. Conventional burs such as the 701, 702, and 703 lack depth indicators and precision, making it difficult for surgeons to measure the amount of bone removal and maintain consistency across procedures. I The SK burs are designed with a universal colour-coding system to indicate specific guttering depths, allowing for improved control and precision. Each bur (SK 1 and SK 2) has clearly marked depths (1.2 cm, 1.6 cm, and 2.0 cm) in blue, green, and red, respectively, facilitating accurate bone removal. This design ensures safer surgeries by minimizing the risk of damage to critical anatomical structures. Apart from this the modifications were done over the neck region of the bur which will prevent the occurrence of bur head fractures, which are common in conventional burs due to their thinner neck design. By providing consistent dimensions and colour-coded depth markings, SK burs offer a practical solution for improved surgical outcomes, enhanced precision, and reduced procedural complications, making them an essential tool in modern oral and maxillofacial surgeries."
