Dental implant guiding tool set and dental implant guiding sleeve thereof

Abstract

A dental implant guiding tool set and a dental implant guiding sleeve thereof are disclosed. The dental implant guiding tool set includes a handpiece, a dental implant guiding sleeve and a tooth mold fastening device. The dental implant guiding sleeve includes a handpiece head guiding hole disposed axially and corresponding to a shape of the handpiece head of the handpiece, a lateral opening disposed on a side of the handpiece head guiding hole and corresponding to a connection handle of the handpiece. The dental implant guiding sleeve can directly guide the handpiece head of the handpiece, to prevent the dental implant guiding sleeve from directly contacting the drill bit mounted on the handpiece. Therefore, a conventional drill bit can be directly used for a guiding dental implant operation, and the minimal required operation space of the dental implant guiding tool set can be reduced.

(20) Please refer to FIGS. 3 to 5, which show a first embodiment of the present invention. A dental implant guiding tool set of the present invention includes a handpiece 101, a dental implant guiding sleeve 20 and a tooth mold fastening device 30.

(21) The handpiece 101 comprises a handpiece head 101a having a replaceable drill bit 102 and configured to provide the drill bit 102 with driving power, and a connection handle 101b connected to the handpiece head 101a.

(22) The dental implant guiding sleeve 20 includes a handpiece head guiding hole 21 corresponding to a shape of the handpiece head 101a and disposed axially, at least one lateral opening 22 disposed on a side of the handpiece head guiding hole 21 and corresponding in position to the connection handle 101b, two locating plates 23 radially disposed on two outer sides of the dental implant guiding sleeve 20 respectively, and a position-limiting plate 24 disposed on a bottom of the handpiece head guiding hole 21 and having a drill bit through hole 25 formed on a center thereof. The dental implant guiding sleeve 20 comprises at least one reinforcing rib 26 disposed on an outer edge thereof and configured to strengthen structural intensity of the dental implant guiding sleeve 20. In this embodiment, the dental implant guiding sleeve 20 has two lateral openings 22 opposite to each other. In actual implementation, the lateral opening(s) 22 can be disposed on one side or both sides of the dental implant guiding sleeve 20 according to the use requirements. The dental implant guiding sleeve 20 can be made by metal material, to make the dental implant guiding sleeve 20 sturdier and more durable for repeatedly use.

(23) The tooth mold fastening device 30 comprises a sleeve hole 31 corresponding to the dental implant guiding sleeve 20 and configured for insertion of the dental implant guiding sleeve 20, two locating accommodation spaces 32 formed on two sides of the sleeve hole 31 and corresponding in position to the two locating plates 23. The tooth mold fastening device 30 can wrap a partial area of the reinforcing rib 26, to prevent the dental implant guiding sleeve 20 from being deformed easily.

(24) When the handpiece 101 is operated, the handpiece head 101a is located by the handpiece head guiding hole 21, and limited to have axial displacement only in the handpiece head guiding hole 21, so that the drilling position of the drill bit 102 can be precisely controlled. Since the handpiece head 101a does not rotate, only sliding friction occurs during the axial displacement of above-mentioned operation, so as to prevent unnecessary excessive friction and abrasion and high heat during the operation.

(25) In a first embodiment, with the configuration of the two locating plates 23 disposed radially and the locating accommodation spaces 32 having the openings arranged in a radial direction, the dental implant guiding sleeve 20 can be laterally inserted to fast and stably fasten on the tooth mold fastening device 30, and when the handpiece head 101a is axially moved in the handpiece head guiding hole 21, the dental implant guiding sleeve 20 can be effectively prevented from being affected by the handpiece head 101a to fall off the tooth mold fastening device 30.

(26) Since the drill bit 102 is not direct contact with the dental implant guiding sleeve 20 and the handpiece head guiding hole 21, the middle section of the drill bit 102 is not subjected to an improper external force, and the displacement and deflected force caused by the handpiece 101 can be directly applied to between the handpiece head 101a and the handpiece head guiding hole 21, and then be eliminated, so as to protect the drill bit 102 well to perform drilling, reaming or grinding operation on the alveolar bone 100.

(27) The lateral opening 22 enables the handpiece head 101a to enter the handpiece head guiding hole 21 deeper, and the drill bit 102 can be in contact with or located in the handpiece head guiding hole 21 without using any additional structure, so that the required space of the entire implant drilling operation can be greatly reduced and the dental implant operation can be more widely applied in more parts of the mouth, for example, it facilitates to perform the dental implant operation on the rear tooth. Furthermore, the cooling water sprayed from the spray hole 104 of the handpiece 101 can be sprayed to the drill bit 102 through the lateral opening 22, so as to ensures the drill bit 102 to be lubricated and cooled during the operation.

(28) The position-limiting plate 24 has the drill bit through hole 25, so that the position-limiting plate 24 only contact the non-rotating handpiece head 101a and does not interfere with the operation of the drill bit 102. When the drill bit 102 starts to enter the handpiece head guiding hole 21, the through hole of the drill bit 102 can properly limit, guide and align the front end of the drill bit 102.

(29) In use, the dental implant guiding sleeve 20 can be in cooperation with the tooth mold fastening device 30, and also can be used alone in the drilling position for dental implant, so as to directly guide the handpiece head 101a.

(30) Please refer to FIGS. 6 to 8. The dental implant operation may be performed on different position, and the teeth near the drilling position possibly have different heights. In an embodiment, in order to fit the periphery teeth having different heights, the two locating plates of the dental implant guiding sleeve 20 can be disposed in the same or different levels, and the depth of the position-limiting plate 24 can be different according to the use requirement. In practical use, various types of the dental implant guiding sleeves 20 can be prepared for a dentist to select in different situation.

(31) Please refer to FIGS. 9 to 12, which show schematic views of the possible implementation types of the reinforcing rib of the present invention. The reinforcing rib 26 is used to reinforce the dental implant guiding sleeve 20, to prevent the dental implant guiding sleeve 20 from being deformed by an applied force to cause shrinkage or expansion. The shape of the reinforcing rib 26 can vary, and the reinforcing rib 26 can be formed on the dental implant guiding sleeve 20 by welding, soldering or directly stamping manner, to achieve the purpose of structural reinforcement.

(32) Please refer to FIGS. 13 and 14, which show the structures of the dental implant guiding sleeve 20 and the tooth mold fastening device 30 according to a second embodiment of the present invention. The difference between this embodiment and the first embodiment is that an opening direction of the locating accommodation space 32 formed in the tooth mold fastening device 30 is changed. The tooth mold fastening device 30 has rotary guide grooves 33 formed on an upper surface thereof and corresponding to the locating accommodation spaces 32, respectively, so that the bottom of the dental implant guiding sleeve 20 can be directly inserted into the sleeve hole 31 axially, and in this case, the two locating plates 23 are first inserted into the rotary guide grooves 33 and then screwed into the corresponding locating accommodation spaces 32, so that the dental implant guiding sleeve 20 can be stably fastened in the tooth mold fastening device 30.

(33) The present invention disclosed herein has been described by means of specific embodiments. However, numerous modifications, variations and enhancements can be made thereto by those skilled in the art without departing from the spirit and scope of the disclosure set forth in the claims.
