In a new research achievement, two researchers from the College of Dentistry at King Khalid University, Dr. Majed Saad Al Touman and Dr. Manar Khalid Al-Amri, have been granted a patent by the Saudi Authority for Intellectual Property
for their invention, an "Adjustable Angled Screwdriver for Dental Implants," designed to facilitate access to dental implant components in confined oral spaces, particularly in the posterior regions of the mouth.
Dr. Al Touman explained that the invention was developed to address challenges encountered during dental implant procedures involving patients with limited mouth opening. Conventional straight screwdrivers can make it difficult to access implant screws in confined spaces, complicating instrument maneuverability, potentially prolonging procedures, and increasing the risk of damaging delicate implant components.
He explained that the invention features a right-angled screwdriver with a 90-degree configuration, incorporating an internal bevel gear mechanism that transfers rotational motion and torque from the handle to the implant screw along a perpendicular axis. This design enables clinicians to manipulate screws in areas that are difficult to access using conventional straight instruments.
He added that the device features a compact design and a detachable, replaceable component that allows compatibility with different dental implant systems without requiring replacement of the entire instrument. Its components can also be manufactured from stainless steel or titanium, supporting durability, sterilization, and reuse in accordance with approved safety requirements.
He noted that potential applications include inserting, removing, and adjusting implant screws, as well as handling healing abutments, impression components, and screw-retained crowns. The design aims to facilitate clinical procedures in areas with restricted access, potentially reducing time and effort, improving patient comfort, and minimizing the risk of damage to implant components when used correctly.
It is worth noting that the two researchers previously obtained a patent for their invention, a "Flexible Gingival Retraction Cord with Adjustable Bands," developed as part of their efforts to advance instruments used in dental procedures.
