Tooth implant system

Abstract

A tooth implant system has an upper abutment, a lower abutment, a crown, and an elastic member securely placed between the upper abutment and the lower abutment providing softer and elastic, yet resilient, cushion between the upper abutment and the lower abutment. To better affix the elastic member within the tooth implant system, a ring lock may be used, securely placed in a ring-lock groove located on the lower abutment section. An insertion of a screw deeper into the lower abutment receptacle pushes the ring lock-groove and the ring lock outwardly to force the elastic member against an inner chamber wall of the upper abutment and into the abutment groove to better securely affix the elastic member.

DETAILED DESCRIPTION EMBODIMENTS OF THE INVENTION

(21) A tooth implant system 10 is described in detail, as shown in FIGS.

(22) FIG. 1 shows a cross-sectional view of the tooth implant system 10 having an upper abutment 15, a lower abutment 20, a crown 25, and an elastic member 30. The elastic member 30 is securely placed between the upper abutment 15 and the lower abutment 20 providing softer and elastic, yet resilient, cushion between the upper abutment 15 and the lower abutment 20. The elastic member 30 may be exposed between a gap 35 between the upper abutment 15 and the lower abutment 20 in between the crown 25 and gum 40, the user's gum 40. The elastic member 30 may even protrude out slightly, or bulge out slightly, between the upper abutment 15 and the lower abutment 20, so no food particle may be trapped between the upper abutment 15 and the lower abutment 20.

(23) The elastic member 30 may be designed to be the same size or substantially (approximately) the same shape and size as the in-between space between the upper abutment 15 and the lower abutment 20, as shown in FIG. 3. However, it is possible to have the elastic member 30 to be a flatter shape, as shown in FIGS. 12-13, that is pliable to fit into the in-between space between the upper abutment 15 and the lower abutment 20, screwed down with a screw 45 (seen in FIG. 5) to bulge out of the gap 35 between the upper abutment 15 and the lower abutment 20. In this configuration, the elastic member 30 would need to be substantially more pliable than a pre-formed shape and would need be trimmed along the gap 35 to make the elastic member 30 smoothly aligned with the upper abutment 15 and the lower abutment 20.

(24) A preferred shape of the elastic member 30, as seen in FIG. 3, is the elastic member 30 designed to be approximately the same shape and size as the in-between space between the upper abutment 15 and the lower abutment 20. The actual shape of the elastic member 30 shaped as a generally flatter shape pliable to fit into the in-between space between the upper abutment 15 and the lower abutment 20 will vary pending the material used for the elastic member 30. In general, the elastic member 30 should be made of plastic, rubber, gold, or other elastic materials commonly used in dentistry. Also, the elastic member 30 may be made of material, formed as a pliable disc, so that when the elastic member is inserted in between the upper abutment 15 and the lower abutment 20, the elastic member stretches and tightly fits into (or forms into) a hollow area between the upper abutment 15 and the lower abutment 20.

(25) The lower abutment 15 is securely screwed into the user's bone 50 using a threaded surface 55 of the lower abutment 15. Although the threaded surface 55 in FIG. 1 is shown in a wide format, the threaded surface 55 of the lower abutment 15 may have various shapes, including but not limited to, much narrow format to better fit limited width of the bone 50.

(26) FIG. 2 shows the tooth implant system 10 having an upper abutment 15, a lower abutment 20, a crown 25, and an elastic member 30. To better illustrate the details of the lower abutment 20, the upper abutment 15 and the crown are shown in their cross-sectional views.

(27) As with FIG. 1, FIG. 2 shows the elastic member 30 securely placed between the upper abutment 15 and the lower abutment 20, providing softer and elastic, yet resilient, cushion between the upper abutment 15 and the lower abutment 20. The elastic member 30 is shown exposed between a gap 35 between the upper abutment 15 and the lower abutment 20 in between the crown 25 and gum 40, the user's gum 40.

(28) The lower abutment 20 has a lower-abutment section 60 and a fixture section 65. The crown 25 securely attaches to the upper abutment 15, and the fixture section 65 securely implants into to a patient's bone 50. A transition line 70 is formed between the lower-abutment section 60 and the fixture section 65. The transition line is located on the lower abutment 20 located at near the gap 35 between the upper abutment 15 and the lower abutment 20. The transition line, although it is not physically marked on the lower abutment 20, it is the transition between the lower-abutment section 60 and the fixture section 65, identifiable by the transition of sloping from the lower-abutment section 60 and the fixture section 65. The circumference of the transition line 70 of the lower abutment 20 has a wider diameter than a narrower diameter located at the lower-abutment section 60 sloping upwards to an upper-lower abutment surface 75, forming a sloping surface of the lower-abutment section 60.

(29) FIGS. 3-5 show the elastic member 30 having an elastic-member hole 80 aligned with an upper-abutment hole 85 of the upper abutment 15 and a lower-abutment receptacle 90 of the lower abutment 20. A screw 45, a threaded bolt, or other frictional securing means is used to securely affix the upper abutment 15 to the lower abutment 20. As an example, a screw 45 inserted and screwed tightly into the upper-abutment hole 85, the elastic-member hole 80, and into the lower-abutment receptacle 90.

(30) FIG. 5 is an exploded view of tooth implant system 10 having an upper abutment 15, a lower abutment 20, and an elastic member 30. A ring lock 95 (also reference FIGS. 8A, 8B, 9A and 9B) that may be securely placed in a ring-lock groove 100 located on the sloping surface of the lower abutment section 60 is shown. The ring lock 95 should have an opening break 96 as shown in FIGS. 8A, 8B, 9A, and 9B. The ring lock 95 better affixes the elastic member 30 and securely fastens the elastic member 30 within the tooth implant system 10. Along with FIG. 6, FIG. 5 shows the upper abutment 15 having an upper chamber 105 with an upper-chamber wall 110, and a lower chamber 115 with a lower-chamber wall 120.

(31) The sloping surface of the lower abutment section 60 and the elastic member 30 fits into the lower chamber 115. A screw 45 slightly larger than the lower-abutment receptacle 90 is used so that the insertion of the screw 45 deeper into the lower-abutment receptacle 90 pushes into the ring-lock groove 100 and the ring lock 95 outwardly to force fit the elastic member 30 against the lower-chamber wall 120 of the upper abutment 15, allowing the gap 35 to be completely sealed (covered and/or filled) by the elastic member 30 so that no food particle may be lodged in the gap 35.

(32) One variation of the tooth implant system 10 has the upper abutment having a post 121 (also shown in FIG. 1) below an upper abutment hole 85 so that the post 121 presses down on the elastic member 30 when the screw secures the upper abutment 15, the elastic member 30, and the lower abutment 20. The post 121 may form a press-down wall 122 along the upper abutment hole 85 (also shown in FIG. 1).

(33) As shown in FIGS. 1-2 and 5-6, the lower-chamber wall 120 of the upper abutment 15 has an abutment groove 125 that receives a pushed-out portion of the elastic member 30 when the screw 45 is inserted and screws into the lower abutment receptacle 90. The insertion of the screw 45 deeper into the lower abutment receptacle 90 pushes the ring lock-groove 100 and the ring lock 95 outwardly to force the elastic member 30 against the inner chamber wall 110 (upper-chamber wall) of the upper abutment 15 and into the abutment groove 125.

(34) As shown in FIGS. 8A, 8B, 9A, and 9B, the ring lock 95 with the opening break 96 may have one or more ring protrusions 130 (also shown in FIG. 7) extended from the inner ring 135 (that is, the inside of the ring lock 95) that fit into one or more pits 140 (also shown in FIGS. 5 and 7) on the ring lock-groove 100. FIG. 9 is a top view of the elastic member 30 with the ring lock 95 in the lower abutment 20. The lower abutment is shown by hidden lines because the lower abutment in these FIGS. are covered over by the elastic member 30. FIGS. 8B and 9B show the ring protrusions 130 longer than the ones shown in FIGS. 8A and 8B. The longer ring protrusions 130 as shown in FIGS. 8B and 9B extend through the pits 140 (through the pits 140 that extend as a tube to the lower-abutment receptacle 90) and contact the screw 45 so when the screw 45 is securely screwed into the lower-abutment receptacle 90, the screw itself pushes the ring protrusion 130 outward and forces the elastic member into the abutment groove 125. The pits 140 may be fully bored through the lower abutment 20 to accommodate the longer ring protrusions 130 as shown in FIGS. 8B and 9B, illustrated in FIGS. 15 and 16.

(35) As seen in FIG. 5, the tooth implant system 10 may have the fixture section 65 of the lower abutment 20 having an indentation 145 so that the bone 50 of the patient would grow into the indentation 145 after the tooth implant system 10 is implanted in the patient. The indentation 145 can be designed as a pass-through hole 150 in the fixture section so that the bone of the patient would grow into the indentation after the tooth implant system 10 is implanted in the patient.

(36) FIG. 10 shows a second version of the tooth implant system 10. The tooth implant system 10 has an upper abutment 15, a lower abutment 20, a crown 25, and an elastic member 30. The elastic member 30 is securely placed between the upper abutment 15 and the lower abutment 20, and the crown 25 is placed securely to the upper abutment 15. The entire tooth implant system 10 is rooted into a patient's bone 50 when the lower abutment 20 is implanted into to the patient's bone 50.

(37) The elastic member 30 may be exposed between a gap 35 between the upper abutment 15 and the lower abutment 20. The elastic member 30 may even protrude out slightly, or bulge out slightly, between the upper abutment 15 and the lower abutment 20, so no food particle may be trapped between the upper abutment 15 and the lower abutment 20.

(38) The elastic member 30 has an elastic-member hole 80 aligned with an upper-abutment hole 85 of the upper abutment 15 and a lower-abutment receptacle 90 of the lower abutment 20. In this configuration, the upper-abutment hole 85 is extended longer than the upper-abutment hole 85 of the previous configuration of the elastic member 30 presented above.

(39) A screw 45, a threaded bolt, or other frictional securing means is used to securely affix the upper abutment 15 to the lower abutment 20. As an example, a screw 45 inserted and screwed tightly into the upper-abutment hole 85, the elastic-member hole 80, and into the lower-abutment receptacle 90.

(40) The upper abutment 15 has an upper-abutment section 155 and a lower-upper-abutment section 160. A transition line 70 is formed between the upper-abutment section 150 and the lower-upper-abutment section 160 of the upper abutment 15. The lower-upper-abutment section 160 has a sloping surface sloping upwards from a smaller diameter at a lower-upper-abutment surface 165 to a wider diameter at the transition line 70.

(41) The upper abutment 15 has an upper chamber 105 with an upper-chamber wall 110. The lower abutment 20 has a lower chamber 115 with a lower-chamber wall 120. As an improvement a ring lock 95 may be used by placing the ring lock 95 on a ring-lock groove 100 to hold the ring lock 95 in place at the sloping surface of the lower-upper abutment section 155.

(42) The sloping surface of the lower-upper abutment section 155 and the elastic member 30 fits into the lower chamber 115. The screw 45 is used to securely hold the upper abutment 15, the elastic member 30, and the lower abutment 20 together. The screw 45 should be slightly larger than the lower abutment receptacle 90 and the upper abutment hole 85 so that the insertion of the screw 45 deeper into the lower abutment receptacle 90 pushes the ring-lock groove 100 and the ring lock 95 outwardly to force the elastic member 30 against the lower-chamber wall 120 of the lower abutment 20.

(43) The lower-chamber wall 120 of the lower abutment 20 has an abutment groove 125 that receives a pushed-out portion of the elastic member 30 when the screw 45 is inserted and screws into the lower abutment receptacle 90. The insertion of the screw 45 deeper into the lower abutment receptacle 90 pushes the ring-lock groove 100 and the ring lock 95 outwardly to force the elastic member 30 against the lower-chamber wall 120 of the lower abutment 20 and into the abutment groove 125.

(44) FIG. 12 is a side view of one possible embodiment of the elastic member 30, and FIG. 13 is a top view of one possible embodiment of the elastic member 30. As illustrated by FIGS. 12-13, the elastic member 30 may have various forms and shapes, including but not limited to the shapes shown in the FIGS. because the elastic member 30 is elastic. As an example, the elastic member 30 may have an oval shape, an elliptical shape, a convex shape, or a concave shape.

(45) FIG. 14 shows a top view of the upper abutment 15 showing a screw 45 inserted into the upper-abutment hole 85. FIG. 14 also shows a crown-mounting ledge 170 on which the crown mounts, an outer-surface 175 of the upper abutment 15, and a top-surface 180 of the upper abutment. The crown-mounting ledge 170, the outer-surface 175 of the upper abutment 15, and the top-surface 180 of the upper abutment are also shown in FIG. 1 and other FIGS.

(46) FIGS. 15-16 are two cross-sectional views of two versions of the tooth implant system 10 showing the ring protrusion 130 reaching the lower-abutment receptacle 90. As illustrated in FIGS. 8B and 9B show the ring protrusions 130 longer than the ones shown in FIGS. 8A and 8B. The longer ring protrusions 130 as shown in FIGS. 8B and 9B extend through the pits 140 (through the pits 140 that extend as a hollow tube to the lower-abutment receptacle 90) and contact the screw 45 so when the screw 45 is securely screwed into the lower-abutment receptacle 90, the screw itself pushes the ring protrusion 130 outward and forces the elastic member into the abutment groove 125. The pits 140 may be fully bored through the lower abutment 20 to accommodate the longer ring protrusions 130 as shown in FIGS. 8B and 9B, illustrated in FIGS. 15 and 16.

(47) FIG. 16 is another cross-sectional view of one version of the tooth implant system 10 showing, as in FIG. 15, the ring protrusion 130 reaching the lower-abutment receptacle 90. The difference between the ring protrusion 130 shown in FIG. 15 and FIG. 16 is that the ring protrusion 130 shown in FIG. 15 has the same thickness as that of the ring lock 95, and the ring protrusion 130 shown in FIG. 16 has a smaller thickness than that of the ring lock 95, thus the pit 140 (the tube) needs to be that much narrower.

(48) FIGS. 17A-17C are various cross-sectional views of the tooth implant system 10 showing the crown 25 and the upper abutment 15 shown in FIG. 17A replaced with a larger and elongated crown 25a and a larger and elongated upper abutment 15a as shown in FIG. 17C. FIGS. 17A-17C show an advantage of the present tooth implant system 10 over the old conventional tooth implant system. If and when the patient's gumline 181 (gum 40) surrounding an earlier implanted tooth implant system 10, as shown in FIG. 17A, recedes due to age, an extended use, gum disease, or whatever a reason as shown in FIG. 17B, because the lower abutment 20 is initially imbedded deeper than the gum line 181 and an upper surface 185 of the lower abutment 20 is shaped similar as shown in FIGS., the old upper abutment 15 and the old crown 25 can be removed and replaced with a new larger and elongated crown 25a and a new larger and elongated upper abutment 15a as shown in FIG. 17C to fully cover up any exposed lower abutment 20. The new larger and elongated crown 25a and a new larger and elongated upper abutment 15a will be placed at (or aligned with) the gumline 181 as shown, eliminating the need to replace the lower abutment 20 or to disturb the bone 50. It should be noted that a differently shaped upper surface 185 of the lower abutment 20 may also be used.

(49) FIG. 18 is a top view of a cross-sectional view of the lower abutment 20 at the pass-through hole 150. Because the pass-through hole 150 in the lower abutment 20 removes a portion of the lower abutment 20, the width ? of the lower abutment 20 is longer than the width ? of the lower abutment 20. The width ? of the lower abutment 20 is the measure of the full diameter of the lower abutment perpendicular to the pass-through hole 150 and the width ? of the lower abutment 20 is the measure of the lower abutment from one end of the pass-through hole 150 to the other. Because the width ? is longer than the width ?, the cross-section at the pass-through hole 15 is not circular, preventing the tooth implant system 10 from rotating once implanted, making the tooth implant system 10 more securely rooted into the bone 50 when completed. Moreover, because the width ? of the lower abutment 20 is narrower than the width a, this version of the tooth implant system 10 may be used where the patient's bone structure is narrow, enabling a broader and stronger implant due to the broader width ? along the line of the patent teeth alignment; that is, along the patent bone alignment; the narrower width ? of the lower abutment can be set to accommodate the narrower bone structure.

(50) As explained above, one option for the tooth implant system 10 is to have the elastic member 30 made of elastic and stretchable material, formed as a pliable disc, so that when the elastic member 30 is inserted in between the upper abutment 15 and the lower abutment 20, the elastic member 30 stretches and tightly fits into a hollow area between the upper abutment 15 and the lower abutment 20.
