[001] The present disclosure relates to the field of tools used to drill a groove configured to receive implant therein. More particularly, the present disclosure relates to rotary osteotomes.

BACKGROUND

[002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.

[003] An implant is a medical device designed to replace, support, or improve a biological structure. Bone implants are a type of implant that are inserted into a patient's bone and can be found in different parts of the human skeletal system. Examples of bone implants include dental implants used to replace a missing or damaged tooth, joint implants that help replace a damaged joint such as in hips and knees, and reinforcement implants that aid in the repair of fractures and other deficiencies, such as pedicle screws that help stabilize the spine. The procedure to insert an implant often involves preparing the bone using either hand osteotomes or precision drills with controlled speed to prevent damage to the bone.

[004] However, corrosion of the osteotome device can occur due to various reasons, including exposure to certain chemicals, improper cleaning and sterilization, and environmental factors may lead to problems such as reduced effectiveness, in which corrosion can affect the cutting ability of the osteotome, reducing its effectiveness in bone surgery. Corrosion can also lead to the build-up of bacteria, debris, and other contaminants on the surface of the osteotome, increasing the risk of infection and other complications. Corroded surfaces can have sharp edges or rough spots that can damage surrounding tissue during surgery. Also, corrosion can weaken the structure of the osteotome, making it more prone to breakage during surgery. This can lead to serious complications and require additional surgical procedures.

[005] Osseodensification is a dental implant technique that involves densifying the bone around the implant site to enhance the stability of the implant. The process involves the use of specially designed drills, such as the osteotome device, to create micro-fractures in the bone, which stimulates the bone to produce new, denser bone. However, conventional osteotome devices, especially without any coating thereon, may result in post-operative pain and swelling, which may occur due to the trauma caused to the bone during the procedure.

[006] Another complication, commonly referred to as Peri-implantitis is an inflammatory condition that affects the tissues around the implant and can cause bone loss, implant instability, and ultimately implant failure. It is important to note that while osseodensification may increase implant stability, it is not a guarantee against peri-implantitis or implant failure.

[007] Therefore, there is a need for an osteotome device, which may be highly resistive to corrosion having good cutting efficacy, good densification of bone and good durability, and cost effective, and thus, formed genesis of this invention.

DETAILED DESCRIPTION

[0017] Before the present apparatus and its components are described, it is to be understood that this disclosure is not limited to the particular apparatus and its arrangement as described, as there can be multiple possible embodiments that are not expressly illustrated in the present disclosure. It is also to be understood that the terminology used in the description is for the purpose of describing the particular versions or embodiments only and is not intended to limit the scope of the present application. This summary is not intended to identify essential features of the claimed subject matter nor is it intended for use in detecting or limiting the scope of the claimed subject matter.

[0018] The present disclosure is related to an osteotome device (hereinafter referred to as osteotome). During densification procedures, the osteotome may be used to compress and compact bone tissue, often in the context of a bone graft or fusion procedure. The osteotome can be used to create channels or cavities in the bone tissue, and then used to compact the tissue and promote the growth of new bone. By compressing the bone tissue, the osteotome can help to increase the density and strength of the bone, which can be beneficial for patients with weakened or damaged bone tissue.

[0019] FIG.1 illustrates a perspective view 100 of an osteotome 102, as an illustrative embodiment of the present disclosure. FIG.2 illustrates a front view 200 of the osteotome 102, as an illustrative embodiment of the present disclosure. FIG.3 illustrates a right-hand side view 300 of the osteotome 102, as an illustrative embodiment of the present disclosure. FIG.4 illustrates a top view 400 of the osteotome 102, as an illustrative embodiment of the present disclosure. FIG.5 illustrates another right-hand side view 500 of the osteotome 102, as an illustrative embodiment of the present disclosure. FIG.6 illustrates a rear view 600 of the osteotome 102, as an illustrative embodiment of the present disclosure.

[0020] With continued reference to FIGs.1-6, the osteotome 102 may include a proximal end 204, and a distal end 208. The proximal end 204 may be connected to a shank 210. The shank 210 may further include a first end and a second end. Further, the proximal end 204 may be located at the first end, and may be defined as an engaging interface, which may be attacked and interlocked within a chuck of a power device, such as for example, a medical drilling equipment. To the second end of the shank 210, a transition 202 may be connected, or fixated thereto. In another embodiment, the diameter of the body may range between 1.5mm-6mm. Further, the transition 202 may act as a base for a body, which may be further illustrated in successive embodiments.

[0021] In another embodiment, from the transition 202, a body may be extended. The body may be formed by a combination of a spiral thread and a helical teeth section defined in the spiral thread. Further, the body may be defined, by the spiral thread in a first region 206a, a second region 206b, and a third region 206c. Further, at the distal end 208, a tetrahedron structure may be defined as a drilling head. However, the number of regions defined by the spiral thread may not be limited to the first region 206a, the second region 206b, and the third region 206c. It may be understood by a person skilled in the art that the spiral thread may define more than three regions on the body of the osteotome 102. In another embodiment, the diameter of the body may progressively decrease, from the transition 202 to the distal end 208.

[0022] In another embodiment, each of the first region 206a, the second region 206b, and the third region 206c may include a first helical section, a second helical section, and a third helical section, respectively. The first helical section, the second helical section, and the third helical section may be defined as flutes. Flutes are teeth, or serrations on the blade, which may be configured to improve cutting efficiency and reduce the amount of force required to make a cut. Further, the flutes may be typically designed, in a helical pattern disposed circumferentially around the first region 206a, the second region 206b, and the third region 206c. The flutes may be configured to grip the bone tissue and help guide the osteotome 102 through the tissue more smoothly, reducing the risk of slipping or causing damage to surrounding tissues.

[0023] In another embodiment, the diameter of the body may influence the number of flutes. For example, the number of flutes present on the body of the instrument may be influenced by the diameter of the body. For example, bodies with diameters ranging from approximately 1.5mm-2.9 mm may include three or four flutes, while those with diameters ranging from 2.5mm-3.9 mm may include five or six flutes. Similarly, bodies with diameters ranging from 3.5mm-4.9 mm may include seven or eight flutes, and those ranging from 4.5mm-5.9 mm may include nine or ten flutes. In the same embodiment, helix angle of each of the flute may range between 5º-20º.

[0024] In another embodiment, and illustrated earlier by way of an example, the tetrahedron structure defined as the drilling head, or a flank, may be formed at the distal end 208. With continued reference to FIGs.5-6, the flank may include a plurality of wedges, or lips. In the same embodiment, the plurality of wedges may continue down to the transition 202, as a flute. Therefore, the plurality of wedges formed on the tetrahedron structure of the distal end may be equivalent to the number of flutes.

[0025] In another embodiment, with continued reference to FIGs. 5-6, the tetrahedron structure may include a transverse angle ranging between 60º-100º, and an internal angle ranging between 80º-120º. Further, as mentioned earlier, the tetrahedron structure may act as a drilling head, and under rotation, the drilling head may be configured to impart a groove on the bone. After the formation of the groove, the plurality of wedges and the lips may be configured to rotate, or drill through the bone, and any effluent resulting due to the action of the drill may be oriented, or moulded onto the bone, thereby increasing the density of the bone around the groove, or densifying the bone.

[0026] In another embodiment, the osteotome device may be manufactured having stainless steel as the base material. Stainless steel is a type of steel alloy that is resistant to rust and corrosion due to the presence of chromium in its composition. Chromium reacts with oxygen in the air to form a thin layer of oxide on the surface of the steel, which acts as a protective barrier against corrosion. In addition to its corrosion resistance, stainless steel is also durable, easy to clean, and has a polished, attractive appearance. It is available in a variety of grades and finishes, making it a versatile material for osteotome device 102.

[0027] However, due Peri-implantitis is an inflammatory condition that affects the tissues around the implant and can cause bone loss, implant instability, and ultimately implant failure.

[0028] Therefore, to prevent such side effects such as pain, and swelling, and to improve healing and regeneration of the bone, i.e., to prevent Peri-implantitis, the osteotome 102 may be coated with colloidal aqueous dispersion of silver nanoparticles, in addition to curcumin nanoparticles as reducing agent. The colloidal aqueous solution may be coated onto the osteotome 102, by using any one of state-of-the-art coating methods such as spray-coating and drying, gel coating, or ultrasound-assisted coating. Further, the osteotome 102 coated with the colloidal aqueous dispersion of silver nanoparticles may exhibit anti-corrosive, anti-microbial, antioxidant, and anti-inflammatory properties.

[0029] Various modifications to the embodiment will be readily apparent to those skilled in the art and the generic principles herein may be applied to other embodiments. However, one of ordinary skill in the art will readily recognize that the present disclosure is not intended to be limited to the embodiments illustrated but is to be accorded the widest scope consistent with the principles and features described herein.

[0030] The foregoing description shall be interpreted as illustrative and not in any limiting sense. A person of ordinary skill in the art would understand that certain modifications could come within the scope of this disclosure.

[0031] The embodiments, examples, and alternatives of the preceding paragraphs or the description and drawings, including any of their various aspects or respective individual features, may be taken independently or in any combination. Features described in connection with one embodiment are applicable to all embodiments unless such features are incompatible.
