Patent number: 11712250Abstract: Tools and methods for expanding a precursor hole in a host material to receive a fixture. The precursor hole is enlarged by a rotary tool having helical flutes and interposed lands. The flutes have a negative rake angle. The lands each have a working edge that cuts the host material when the tool is rotated in a cutting direction, and that condenses the host material when the tool is rotated in a densifying direction. The body of the rotary tool has a stopper section that plugs the hole when a certain depth is reached. When the tool is used with a copious wash of irrigating fluid at or below the necessary depth, hydraulic pressure builds inside the precursor hole. The hydraulic pressure can be advantageously exploited in cutting mode to autograft a slurry of host material particles into the sidewalls of the hole and create an incipient densifying crust.Type: GrantFiled: September 20, 2022Date of Patent: August 1, 2023Assignee: Huwais IP Holding LLCInventor: Salah Huwais

Publication number: 20220047359Abstract: An anchor to be screwed into a hole with high primary stability and eventually even higher secondary stability. A right hand thread form winds with continuous turns along the body of the anchor. A trailing flank of the thread form is back-angled. The central region includes an array of flutes having left-hand helical twist. Each flute is composed of distinct flute segments. A condensing ramp is formed along the crest of the thread form between two circumferentially—adjacent flute segments. Each condensing ramp is pitched about 20° so as to apply a localized compressive strain to the interior surface of the host bone with a densifying action when the anchor is screwed into the prepared hole. The condensing ramps create induced stress and super-activated zones in the bone directly adjacent to healing chambers formed by the flute segments. The healing chambers draw bone to naturally encourage and promote healing.Type: ApplicationFiled: October 22, 2019Publication date: February 17, 2022Applicant: Huwais IP Holding LLCInventor: Salah Huwais

Patent number: 10912595Abstract: An anchor to be screwed into a hole and self-lock therein with high initial stability. The anchor has an aggressively-threaded, self-tapping apical end. A central region of the anchor is formed with a plurality of helical flutes and intervening lands. Each land carries a condensing edge. The condensing edges are configured to apply a circumferentially sweeping compressive strain to the interior surface of the host material while the anchor is being screwed into position. A coronal end of the anchor includes a corking feature to mitigate mushrooming around the perimeter of the hole. A helical groove intersects the condensing edges and flutes. The helical groove has a variable pitch and a decreasing depth which functions to squeeze and displace trapped host material thereby enhancing stability and other benefits. In bone applications, the groove hosts material chips which promote and enhance healing.Type: GrantFiled: February 6, 2017Date of Patent: February 9, 2021Assignee: Huwais IP Holding LLCInventor: Salah Huwais

Patent number: 10568639Abstract: A surgical method and tool for expanding an initial osteotomy (42) to receive a bone implant (44). An osteotome (22) having a tapered working end (28) is inserted into the initial osteotomy (42). The initial osteotomy (42) is enlarged by simultaneously rotating and pushing the working end (28) of the tapered osteotome (22) into the osteotomy (42). When rotated in one direction the burnishing edges (40) concentrate the pushing and rotational force in outward normal and tangential component forces against the interior surface of the osteotomy (42) to incrementally expand the osteotomy (42) with little to no removal of bone material (46). When rotated in the opposite direction the burnishing edges cut the interior surface of the osteotomy. Progressively larger tapered osteotomes (22) are used until an osteotomy (42) of predetermined size is achieved.Type: GrantFiled: July 13, 2017Date of Patent: February 25, 2020Assignee: Huwais IP Holding LLCInventor: Salah Huwais

Patent number: 10039621Abstract: A fluted osteotome is rotated in one direction to enlarge an osteotomy by burnishing, and by cutting/drilling when turned in an opposite direction. A conic-ally tapered body has an apical end with lips. The lips are set to grind bone when rotated in the burnishing direction and cut bone when toned in the cutting/drilling direction. Helical flutes and interposed lands are disposed about the body. The flutes each have a working edge that burnishes bone when rotated in the burnishing direction and cuts bone when turned in the cutting/drilling direction. The lips and lands generate an opposing axial reaction force that improves surgical control. The osteotome auto-grafts bone by reapplying ground particles in a compacted manner along the entire depth of the osteotomy, particularly at the bottom.Type: GrantFiled: August 19, 2013Date of Patent: August 7, 2018Assignee: Huwais IP Holding LLCInventor: Salah Huwais

Patent number: 9918764Abstract: An anchoring implant to be screwed into a hole and self-lock therein with secure stability. The implant, which may be used in dental, orthopedic or any of several non-medical applications, has a conically tapered profile with an aggressively-threaded, self-tapping apical end. A central region of the implant is formed with a plurality of burnishing edges each configured to apply a circumferentially sweeping compressive strain to the interior surface of the hole with a burnishing action while the implant is being screwed into position. A coronal end of the implant includes a corking feature to avert mushrooming around the perimeter of the hole. A central thread profile may extend through and intersect the burnishing edges to provide either enhanced self-tapping or enhanced corking functionality. The extreme coronal end comprises a platform for receiving an abutment or other fastening element via an internal connect feature.Type: GrantFiled: December 11, 2013Date of Patent: March 20, 2018Assignee: Huwais IP Holding LLCInventor: Salah Huwais

Publication number: 20170071704Abstract: Methods and tools for expanding a precursor hole in a host material to receive an anchor or fixture. The precursor hole is enlarged by a rotary tool having helical flutes and interposed lands. The lands each have a working edge that densities bone when the tool is rotated in a non-cutting direction. When the tool is used with a copious wash of irrigating fluid, hydraulic pressure builds inside the precursor hole. The operator can modulate the hydraulic pressure by axially stroking the rotating tool. The working edges sweep against the interior surface of the hole to gently expand its diameter by incremental plastic deformations with little to no removal of host material. The host material may be bone and the hole formed may be an osteotomy that is prepared with dense, compacted sidewalls to receive a bone implant with a high degree of primary stability.Type: ApplicationFiled: March 13, 2015Publication date: March 16, 2017Applicant: Huwais IP Holding LLCInventor: Salah Huwais
