Color safeguarded dental-implant surgical kit with drilling-depth limiter

Abstract

An apparatus is an implant-dentist more readily identifiable visual segregation amongst their oral-surgery arbor-tools used conjunction with a conventional hand-held power/rotary-tool. The arbor-tools generally has at least a tri-echeloned set, wherein are included progressions of drill-bit lengths and companion thread-taps appearing in three different diameters. Additionally, the drill-bit shanks are optionally provided with a radial-flange serving as an automatic depth-stop device and these radial-flanges may include a distinctive annular-marker device serving to readily indicate the length of the selected drill-bit, thereby obviating usual procedure of stopping to confirm via the obscure conventional alpha-numeric indicia.

[0040] Initial references given by way of FIG. 1 prior art wherein is exhibited an implant-dentist's surgical-kit delivery-tray 29 which top-surface 29 is of conventional design organizational configuration and the array of arbor-tools 29 are of a common look-alike color regardless as to the subtle differences in drill-bit diameters. Hence, such ordinary configurations (exact arrangements and numbers of implements can vary considerably) are thus inefficient to use to the extent of posing the risk of serious confusion during selection of essentially look-alike arbor-tools set into a common panel area: thus unwittingly impeding the implant-dentist's need for seamless procedures and even imperiling patient safety during intense oral-operations.

[0041] In contrast, study of FIG. 2 reveals the greatly improved implant-dentist surgical-kit delivery-tray 10 having extensively reconfigured face surface 10 features, which employ color-coordinated guide-graphics to thoughtfully provide a major streamlining of time and motion procedures through judicious use of color-coding discretely coordinated with selected rotary implements to greatly simplify the formerly encumbered delivery-tray component selection task-procedures. More specifically, note how the arbor-tools are now logically segregated into three distinct corrals referred to herein as unidiameter-groups 15, 15, 15: the unidiameter-group 15 presenting the small-diameter arbor-tools all uniformly finished in a 1.sup.st-color, the unidiameter-group 15 presenting the medium-diameter arbor-tools all uniformly finished in a distinctively different: 2.sup.nd-color, and the unidiameter-group presenting the large-diameter arbortools all uniformly finished in a further distinctively different 3.sup.rd-color.

[0042] Importantly, the three separate corral-like unidiameter-groups revealed in FIG. 2 are made visually distinct to the implant-dentist by means of graphic surround devices employing the same identical color as the arbor-tools which they present. These graphic devices can be as elementary as a simple narrow outline of color represented in FIG. 2 via band 14, or a broadly surrounding field 14, or merely a discrete color encirclement 14 (which may be an actual holding grommet 17 molded of a color matching the unidiameter arbor-tool which it is presenting). Of these exemplified graphic devices, the field surround option 14 may offer the most interesting design potential as FIG. 3 shows how it can actually be implemented in the form of a transparent plastic injection-molded insert-panel 16, shown therein in three distinctively different colorations, such as a green-tint matching the arbor-tools color of the small unidiameter-group 15, an amber-tint matching the arbor-tools color of the medium unidiameter-group 15, and a violet-tint matching the arbor-tools color of the large unidiameter-group 15; and if one of the unidiameter-groups presents arbor-tools which are left in their natural metal-finish state, the insert-panel 16 can likewise be regarded as tantamount to color-coded us an untinted transparent polycarbonate-plastic (highly autoclave-temperature resistant).

[0043] Within each of the exemplified unidiameter-groups of FIG. 2 are included traditional incremental progressions (action ref.-arrow 27) of drill-bit lengths, for example, in the rearmost position of the unidiameter-group 15 representing only a 1.sup.st color of 3.4 mm diameter arbor-tools is shown the shortest drill-bit 11 which is preferably 10 mm long, then the next drill-bit 11 is preferably 12 mm long, followed by the longest drill-bit 11 preferably 14 mm long, and next in view is the associated dental-osseous thread-tap 11T, and finally the nearest rotary-tool being the cooperative 3.4 mm wrench socket 11S. It is important to understand that the very same logical progressions are provided in the next (laterally toward the right) two adjoining albeit different 2.sup.nd-color 4.1 mm unidiameter-group 15, and different 3.sup.rd-color 5.1 mm unidiameter-group 15; therefore, the implant-dentist can also translate laterally (action ref.-arrows 27 and 27) as desired, confident in knowing that their drilling depth will remain constant unless they intentionally elect to progress further via ref.-arrow 27. Moreover, if desired, the three exemplified different hue-colors can also be made to vary in chroma, according to their respective progressions in depth; thus the actual hue-colors remain the same, although they ail appear to vary in surrounding field shade from a lighter-shade at rear positions 11/12/13 toward a darker-shade of the same hue-color for field surround positions 11/12/13.

[0044] This constant-hue/variable-shade effect is basically analogous to the way a printer's Color-wheel chart designed, with white (max.-intensity) at center-axis of the Color-wheel and the different colors surrounding the axis somewhat like spokes of a wheel, with the rim being essentially black (min.-intensity). The notion being to provide not only the different hue colors from left-to-right, but optionally different gradations of those discrete colors from rear-to-front as well. However, the primary intent this disclosure set forth the basic notion of different distinguishing colors (hues) according to the different exemplified unidiameter-groups 15/15/15: the additional optional provision of variable hue-values within each of the unidiameter-groups being merely a further refinement.

[0045] Note also that while FIG. 2 shows the arbor-tools furnished with the novel depth-stop radial-flange having a perimeter 20 diameter approximately twice the diameter of its host drill-bit diameter, it is to be understood that the improved delivery-tray 10 will also serve dental arbor-tools not equipped with the radial-flange; hence appearing substantially like the conventional arbor-tools shown in FIG. 1, with the major exception that the arbor-tools of FIG. 2 necessarily feature the essential color-coding finish (with or without the radial-flange option). At far right of FIG. 2 is shown a removed exemplified drill-hit 13, which is tipped at an angle whereby the radial-flange abutting-surface 2, proximal shank 19, and exemplified coupling tip 19 portion are in view: and it is understood that the design the twist-drill flutes and coupling-tips can vary substantially according to manufacturing design choice, and therefore bare no significance to the disclosure.

[0046] There remain subtle, however vital other differences which are to become herein more evident and understood as important improvements. For example, in FIG. 4 is shown a triad of substantially conventional dental-implant factory-packaging in the form of generally transparent glass or plastic vials 23 having novel color-coded injection-molded plastic vial-caps 22, 22; and 22, each vial-cap being intimately adapted to and preferably press-fitting (a mild friction-fit sufficient to maintain a hermetic-seal) into the vial opening 23, each vial preferably including its own discretionary matching color-coded labels 23L, 23L and 23L applied to the respective sidewall 23 of the individual conventional vials (corresponding to the matching color-coded vial-caps). Shown partially withdrawn in FIG. 4, thus protruding-up from each of the vials 23, are the sterilely contained different unidiameter-group dental-implants 24, 24 and 24 which can compromise both the 1.sup.st-stage (S) and 2.sup.nd-stage (S) portions of the dental-implant, and are optionally factory-assembled via a coaxial Allen/assembly-screw (the upper-tip of which is shown atop the abutment-post portion of the indicated 2.sup.nd-stage (S)). Also shown conventionally pressed into the normally enclosed end of each vial-cap 20, 20, and 20 are unique discretely color-coded but otherwise conventional so-called healing-caps 25, 25 and 25, each essentially comprising a machine-screw which male screw-threaded shank portion is commonly pressed into a retainer-bases 23R, and thus become protectively enclosed within the vial. Other than the novel color-coding feature, this exemplifies a conventional packaging arrangement facilitating convenient accessibility of the healing-cap from each vial-cap's retainer-base 23R once the implant-dentist has installed the 1.sup.st-stage dental-implant portion, and therefore must seal-off the longitudinal central-core of the 1.sup.st-stage primary/dental-implant to prevent problematical foreign matter entering therein during osseointegration of the 1.sup.st-stage. Each healing-cap thus employs a distinct color matching the color of its respect vial-cap; and whereby later, when the implant-dentist decides the osseointegration of the earlier installed dental-implant is satisfactorily merged with the patient's osseous, the implant-dentist (or a subsequent dentist dealing primarily with preparation of crowns) has merely to observe the particular color (hue) of the exposed healing-cap 25, 25, and 25 as to thereby which 2.sup.nd-stage implant portion to select for attachment upon the ensconced 1.sup.st-stage dentist-implant member. The 2.sup.nd-stage implant portion rises above the patient's soft gum-tissue, and generally features an abutment-post portion serving to solidly support the final realistic appearing ceramic prosthetic-tooth crown.

[0047] Study of FIG. 4 clearly shows the radial-flange depth-stop provision which is advantageously positive-acting in drilling limitation, as compared to passively-acting conventional dental drill-bits featuring mere incremental depth reference demarcations of one sort or another upon their medial-shank region. This depth-limiting radial-flange is vital in keeping with the basic procedural safeguarding premise of the most preferred embodiment. As initially revealed in FIG. 2, the radial-flange configuration preferably presents horizontally flat disk area portion, referred to as abutting-surface 20: and because this surface serves to interface direct upon the patient's bony oral-osseous (see FIG. 6). It is considered important this abutting-surface 20 not be tapered up from the drill-flute region, as that would tend to provide a less positive depth-limit action, although an alternate reverse under-cut 20 formation (e.g.: which cross-section is revealed at center of FIG. 3) is an acceptable alternative embodiment.

[0048] The FIG. 4 presentation reveals an alternate optional embodiment for the radial-flange's perimeter surface 20P which until now has been shown as merely plain, remiss of special markings; thus here are shown several iterations of the optional radial-flange embodiment with a practicable annular demarcation means, serving to readily confirm at a glance by the implant-dentist, the particular length of a selected dental drill-bit: thereby obviating need for interruptive reference to the difficult to read alpha-numeric indicia inscribed upon the arbor-tool's upper-shank surface. Beginning at far left, exhibit-A, shows a side-view of a dental drill-bit having the depth-limiting radial-flange which left-perimeter 20P is by way of comparison, of plain unadorned design, while for convenience of illustration the right-perimeter portion is shown with an exemplified integrally formed annular-rib 21X device, which is for purposes of this disclosure regarded at tantamount in function to the exhibit-B iteration, which, perimeter surface is provided with a single annular-groove 21. Note that all FIG. 4 embodiments can thus employ either the integral annular-rib 21X or annular-groove 21 configuration, albeit preferably, consistent as to implementation of either embodiment according to factory engineering-design choice. Thus progressing still further toward the right, exhibit-C, shows the perimeter surface provided with a double annular-groove 21, while the final exhibit-D, at far right, feature s a triple annular-groove 21. Therefore, these preferred radial-flange demarcations (whether formed inwardly or optionally outwardly), in combination with the color-coding system, represent a swift yet sure means by which the implant-dentist can work among their various arbor-tools with absolute confidence, while virtually liberated from the heretofore problematical (time and motion wasting distraction) procedure of having to stop to closely examine a drill-bit's obscure indicia in order to confirm that the drill-bit they've selected is indeed both the correct diameter and length.

[0049] Note also in FIG. 4 that since the opposing upper-surface 20 of the radial-flange serves no particular function, it may be of any desired circular formation such as flat F, tapered T or ball-tapered B1. Moreover, FIG. 4 supports the notion that the differently color-coded radial-flange equipped dental drill-bits may be worked in lateral coordination without confusion, when taken relative to the FIG. 2 delivery-tray face surface 10 graphics (e.g.: encircling discretely color-coded bands 14 identifying the three exemplified diameter-groups 15, 15 and 15) during the ostectomy procedure. Thereby advantageously eliminating heretofore need of generally fidgeting with an ungainly depth gauge, in which a separate probing-tool necessitates repeated removal of the trauma imposing dental drill-bit, and undesirable if tedious procedure. Since conventional dental drill-bits bearing mere depth reference-markings, offer no actual positive means of preventing the implant-dentist exceeding of a critical drilling-depth restrictions, generally determined in conjunction with intermittent X-ray visualizations for example: then it can thus be understood the utility value of discretely color-coded unidiameter-grouped dental arbor-tool drill-bits, each equipped in novel combination with this depth-limiting radial-flange; providing a uniquely safeguarded oral-osteohomy procedures.

[0050] Next, study of FIG. 5 shows an exemplified dental drill-bit 11 having first bored down into the patient's osseous 26, once the comparatively soft-tissue 26 (gum material) is surgically relieved at circumscribed region residing between indicatorsX and X. Whereupon the implant-dentist may determine they need to laterally transfer 27 (see FIG. 2) to the next larger diameter albeit the same depth, selects drill-bit 12 from adjacent differently color-coded unidiameter-group 15 and completes that drilling procedure, but then after further evaluation determines they should make a further lateral transition 27 into unidiameter-group 15 via selection of further differently color-coded dental drill-bit 13 via final progression 27. At this advanced juncture, the implant-dentist completes the oral-ostechomy procedure by chasing down the final pilot-hole bore via threading-tap 13T (see FIG. 2), thereby having completed preparation of the osteotomy-site for initial installation of the actual conventional stage-one dental-implant prosthesis for subsequent osseointegration.

[0051] Thus, it is readily understood how the preferred and generic-variant embodiments of this invention contemplate performing functions in a novel way not heretofore available nor realize. It is implicit that the utility of the foregoing adaptations of this invention are not necessarily dependent upon any prevailing invention patent: and, while the present invention has been well described hereinbefore by way of certain illustrated embodiments, it is to be expected that various changes, alterations, rearrangements, and obvious modifications may be resorted to by those skilled in the art to which it relates, without substantially departing from the implied spirit and scope of the instant invention. Therefore, the invention has been disclosed herein by way of example, and not as imposed limitation, while the appended Claims set out the scope of the invention sought, and are to be construed as broadly as the terminology therein employed permits, reckoning that the invention verily comprehends every use of which it is susceptible. Accordingly, the embodiments of the invention in which an exclusive property or proprietary privilege is claimed, are defined as follows.
