20080254409 | Method for Manufacturing Dental Scaler Tip Using Powder Injection Molding Process, Mold Used Therein and Scaler Tip Manufactured by the Same - The present invention relates to a method for manufacturing a dental scaler tip using a powder injection molding process which can produce the article in large quantities to save the manufacturing cost and forms an eccentric discharge port of a scaler tip to operate the mould using only one core pin, a mould used for the same that is provided with slide cores having the various shapes machined according to the article to enable the uniform article to be manufactured rapidly to enhance a characteristic and design of the article, and a scaler tip manufactured by the same that is more excellent in shape-reliability and injects fluid to a front end thereof along a curved section of the tip section to perform effectively an operation. In order to embody the above structure, the method for manufacturing a dental scaler tip consisting a coupling section mounted to the equipment and having a fluid passage formed therein and a curved shaped tip section extended from the coupling section, through a powder injection molding process, comprises the steps of preparing feedstock for injection by means of mixing raw material powder for the powder injection molding process containing titanium (Ti) or stainless steel with high molecular binder; and injecting the feed stock into a mould to form a molding body, wherein, the mould comprise an operating section to which cylindrical shaped core pins having multi steps and an eccentric end formed at a front end thereof for forming the fluid passage of the scaler tip is mounted; and a pair of slide cores disposed for supporting the eccentric ends of the core pins such that the slide cores face to each other and are slid in the direction perpendicular to the movement direction of the core pins to form a cavity corresponding to a shape of an article to be formed by an injecting process. | 10-16-2008 |
20090011383 | Extrasonic Scaler - An extrasonic scaler includes a triangulate straight scaler, a leftward bent arc-shaped triangulate scaler, a rightward bent arc-shaped triangulate scaler, a leftward bent distal-hoe semi-triangulate scaler, a rightward bent distal-hoe semi-triangulate scaler, a leftward bent mesial-hoe semi-triangulate scaler, and a rightward bent mesial-hoe semi-triangulate scaler. Thus, the extrasonic scaler is designed according to the tooth pattern of the human body so that the extrasonic scaler can reach the deeper surface of the tooth root from various different directions to remedy the oral and periodontal diseases, thereby enhancing the working efficiency. | 01-08-2009 |

20100184000 | PERIODONTAL SCALER - A periodontal scaler is provided, comprising an arcuate shank and an arcuate blade. The arcuate blade being designed to conform to the roughly cylindrical surfaces found on the roots of teeth. This conforming feature of the instrument's blade increases its cleaning efficiency by maximizing contact between the blades surface and the root, and guiding the instrument along the root by holding its convex edges within the concave shape of the blade. | 07-22-2010 |
20100184001 | AREA-SPECIFIC DENTAL INSTRUMENT - An area-specific dental instrument is provided, which comprises an arcuate S-shaped shank and an arcuate blade further comprising a sharpened convex surface. This instrument can be capable of cleaning plaque and calculus from the lingual surfaces of anterior teeth and concave surfaces between teeth at the cemento-enamel junction. | 07-22-2010 |
20100240006 | DENTAL SCALER TIP FOR DENTAL IMPLANT AND MANUFACTURING METHOD OF DENTAL SCALER TIP - Disclosed are a scaler tip for a dental implant using a Powder Injection Molding (PIM) of silver, copper, a silver alloy, or a copper alloy, and a method for manufacturing the scaler tip. The scaler tip includes a shank portion, and a work portion extendedly formed from an end of the shank portion and including a curved portion. Here, the scaler tip is formed by performing the PIM on at least one metal powder of silver, copper, the silver alloy, and the copper alloy. | 09-23-2010 |
