Surgical drill guide aimed at locating ideal position for dental implants in edentulous patients

Abstract

This document describes a set of surgical drill guides for the upper and lower jaw, the guides aimed at locating the ideal position for dental implants in edentulous patients. The guides are made up of a surgical stent material from metal or other rigid material that is aligned to provide support and stability of fully edentulous upper and lower jaw to orient surgical drills in the area of operation. The present embodiment comprises a U-shape metal plate provided form or shaped resembling a toothless upper or lower jaw and containing a top surface of the surgical stent that is contacting the soft tissue of maxilla or mandibula and the bottom surface of the stent that has the same shape as a top one.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0077] An embodiment of set of surgical drill guides aimed at locating the ideal position for dental implants in edentulous patients for upper and lower jaws 10 and 30 respectively, of present invention, is shown in FIGS. 1-13.

[0078] Referring to FIG. 1, a surgical drill guide for upper jaw 10 is generally fan-shaped in plan. One embodiment 10 includes a base portion 17. The base is normally defined by an arcuated buccal wall 19 and this wall 19 extends mostly vertical from the base portion 17 and the created outer edge 15. The upper surgical guide comprises at least two plates: top plate 11 and bottom plate (not shown), which are connected together by means of screws 41. In addition, the present embodiment 10 is provided with a palatal upwardly convex extending arch surface 26.

[0079] Preferably, each surgical guide consists of at least 2 plates: top plate 11 and 12 respectively and bottom plate 13 and 14 respectively, which are connected together by means of screws 41 (see FIGS. 1-6);

[0080] As illustrated in FIG. 2 surgical drill guide for upper jaw 10 contains base portion 17 in which is located the major perforated L track 65, consisting of perforated portion and narrowed portion 66 and added by supplemental short slots 67. The base portion 17 is connected from mesial side to the top plate 11 and connected with bottom plate (not shown) by screws 41 which follow by the palatal upwardly convex extending arch surface 26 and the lingual wall 21 of surgical drill guide 10 and forms the outer lingual edge 24 and from the distal side base portion 17 defined by arcuated buccal wall 19.

[0081] Therefore, the surgical guide for upper jaw 10 is provided with spherical upwardly palatal ledge extension which covers the area between outer edges 15 and 23 of base portion 17 for better support and stability of surgical guide as illustrated in FIG. 2.

[0082] As seen in FIG. 3, the main member 10 comprises a bottom plate 13. The bottom plate lengthens and forms the lingual wall 21 and the outer lingual edge 24. The lingual outer edge extends from the base portion 17 in which the major perforated L track 65, consisting of a perforated portion and a narrowed portion 66, combined with supplemental short slots 67 that are located and which in turn ends by outer edge 15. The mesial to lingual edge is situated lingual upwardly extending arch concave surface 25. The bottom plate 13 is connected with the top plate (not shown) by screws 41.

[0083] As a shown in FIGS. 1-3, the top 11 and bottom 13 plates of surgical guide for upper jaw 10 have a fan-shaped design.

[0084] Referring now to FIG. 4, a surgical drill guide for lower jaw 30 is mostly U shape in design. The one embodiment 30 comprises a base portion 18. The base is normally defined by an arcuated buccal wall 23 and this wall extends typically vertical from the base portion 18 and the outer edge 16. The surgical guide for lower jaw 30 comprises at least two plates: top plate (not shown) and bottom plate 14, which are connected together by means of screws 41. In addition, the present embodiment 30 is extended by the lingual wall 22 and the forming outer lingual edge 20. In addition, the present embodiment encloses the major perforated L track 65, containing the perforated portion, and the narrowed portion 66 in addition to the supplemental short slots 67.

[0085] An additional lingual wall 21 of lower surgical guide connects to the base portion of the lower surgical guide 18 and forms an internal angle 20 of approximately 90 degree.

[0086] As shown in FIG. 5 one embodiment 30 comprises by top plate 12. The top plate lengthens and developing lingual wall 22 and outer lingual edge 20. The lingual outer edge extends and creating base portion 18 in which the major perforated L track 65, consisting of a perforated portion and a narrowed portion 66 in addition to the supplemental short slots 67 that are located and which in turn ends by outer buccal edge 16. The top plate 12 is attached to the bottom plate 14 (not shown) by screws 41.

[0087] As demonstrated in FIG. 6 surgical drill guide for the lower jaw 30 contains a base portion 18 in which is located the major perforated L track 65, consisting of perforated portion and narrowed portion 66 in addition to supplemental short slots 67. The bottom plate 14 is connected to the top plate 16 (not shown) by screws 41. From distal side base portion 18 is defined by arcuated buccal wall 23. The base portion is extended by creating outer buccal edge 16. The bottom plate lengthens and developing lingual wall 22 and outer lingual edge 20.

[0088] As shown in FIGS. 1-6, the arcuated buccal walls 19 and 23 relatively connected to the bases portions of the surgical guides 17 and 18 correspondingly and form an angle of approximately 90 degrees.

[0089] With continue reference to FIGS. 1-6 it is desirable that each base 17 and 18 correspondingly is generally defined by the arcuated buccal edges 15 and 16 respectively and the arcuated lingual edges 17 and 20 accordingly.

[0090] As shown in FIGS. 4-6, preferably the top plate 12 and bottom plate 14 of surgical the surgical guide for upper and lower jaws correspond to the forms and contour of upper and lower jaws of the patient. Each surgical guide includes a base portion 17 and 18 respectively. Each base is defined by an arcuated front walls 19 and 23 respectively (see FIGS. 1-6).

[0091] With continuing reference to FIGS. 7-9, another embodiment of the mounting navigated device 59 of present invention is shown. Mounting navigated device comprises a guided tube 60 and plate 61. The mounting navigated device extends from the rotatable head 62 in the top and may comprise collar 63 and drill guided sleeve 64 as seen in FIG. 7-9.

[0092] As illustrated in FIGS. 7, 8, 9, the mounting device 59 may be constructed from a rigid material such as metal or plastic and mounted and aligned to orientation marks according to position of natural teeth in the patient mouth.

[0093] The mounting navigated device extends from rotatable head 62 in the top and may comprise the collar 63 and the drill guided sleeve 64 (see FIGS. 7-9).

[0094] Referring to FIG. 10, one embodiment of a major perforated L track 65 fitting mounting navigated assembly includes but is not limited to a rotatable head 62 and drill guided sleeve 64. In this particular embodiment, the rotatable head is used to fix in the desired position the mounting navigated device for subsequent drilling with a drill through guided sleeve 64 and guided tube 60 (not shown). It is contemplated that the guided sleeve and the guided tube is 2 mm or more, although the sleeve and the tube can be varied depending on the implant system. In fact, because guided tube 60 is positioned above the top surface of L track, the narrowed portion 66 and the supplemental short slots 67, the diameter of plate 61 (not shown) is not limited by the width of the diameter of the track. The locking mechanism or plate 61 (not shown) is shaped to match the outlines of L-track.

[0095] With reference to FIGS. 11, 12, 13, the major perforated L track 65 is comprised of a plurality of supplemental short slots 67 which are interspersed with narrowed portions of track 66 corresponding to the natural position of absent teeth.

[0096] The internal profile outlines of FIGS. 11-13 show the contours of the main L track 65 space underneath, containing shapes of the supplemental short slots 67 and the narrowed portions of the track 66.

[0097] FIG. 14 illustrates an example how the drill can be generally handled by a headpiece to be installed and inserted into a mounting device of surgical guide.
