DETAILED DESCRIPTION

[0023] The present disclosure is to be considered as an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated by the figures or description below.

[0024] The present invention will be described by referring figures. FIGS. 1, 2 and 3 depict exploded views of the elements that comprise device for double papillae sparing incision in prototype A.

[0025] FIG. 1 depicts exploded parts of prototype A with blades facing down. 101 is half elliptical blade. 104 is thumb rest. 105 is index finger rest. 106 is concave surface, resembling skateboard.

[0026] FIG. 2 depicts exploded illustration of view of prototype A with blades facing up. Blades 201 and 202 are parallel to each other. 203 is perpendicular to both 201 and 202. 204 is thumb rest and 205 index finger rest.

[0027] FIG. 3 depicts exploded illustration of side view of prototype A with blades pointed to the right side. Blades 301 and 302 parallel to each other. Blade 303 is half round blade perpendicular to 301 and 302. 304 and 305 represent finger rests with slight concavities in form of typical thumb and index fingers, respectively for improved grip and safety. 306 is concave surface. 307 is distance between blades 301 and 302. 307 will come in various standard widths similar to present day punch biopsy devices (like 6, 7, 8, 9.10 mm).

[0028] To determine correct size 307 for a specific missing tooth need to measure distance between two teeth intraorally. Thus, for illustrative purposes “G” is distance between two teeth. To ensure preservation of both papillae “G” has to be at least slightly longer than 307. Then after determining 307 from measuring “G”, try device between two teeth to make sure the fit is correct.

[0029] Try slightly rolling device without placing pressure by securely holding at rests to buccal side to see whether vertical incisions do not undermine both papillae. To make incision apply apical pressure while holding at rests with both thumb and index finger with significant pressure until feel crestal bone between teeth. Afterwards, apply light rolling motion to the buccal side while applying pressure on top of bone. Roll until reaching desired length for vertical incisions.

[0030] Please refer to FIGS. 4, 5 and 6 for parts in Prototype B. FIG. 4 depicts exploded view of Prototype B with blades facing down. 401 is full round blade parallel to the other blade (not shown due to view) capable of rotary motion around their common axis, 403. 403 is center of rotation for both blades 401 and 402. 404 is thumb rest, 405 is index finger rest. 407 is a protective cap, to protect from unwanted injuries and to hold the device.

[0031] FIG. 5 depicts an exploded view of Prototype B with blades facing up. Round blades 501 and 502 are parallel to each other. 503 is center of rotation. 504 is thumb rest and 505 is index finger rest.

[0032] FIG. 6 depicts exploded side views of Prototype B with blades pointed to the right side. Round blades 601 and 602 are parallel to each other. 604 is thumb rest and 607 is distance between blades 601 and 601.

[0033] Main differences between Prototypes I and II are as follows. Two parallel blades are half-elliptical and stationary in Prototype A. Two parallel blades are circular and revolving in Prototype B.

[0034] Cover or “cap” in Prototype B protects both patient and operator and also acts as finger rests. Instructions on use for Prototype B are similar as above-mentioned use for Prototype A. However, since crestal incision is missing in Prototype B, need #15 Blade to do crestal incision after performing incision with Prototype B.

[0035] Prototype A PROS vs #15 Blade. [0036] More ergonomic design [0037] Easier incision [0038] Less procedural time [0039] Less blood loss [0040] Less patient anxiety (patient does not see blade or scalpel)

[0041] Prototype B PROS vs #15 Blade are as follows: [0042] More ergonomic design [0043] Easier incision [0044] Less procedural time [0045] Less blood loss (because of less procedural time) [0046] Less patient anxiety (no blade or scalpel visible to patient) [0047] Less effort (Newton's third law)

[0048] Prototype A and B CONS [0049] May need adjustment with #15 Blade. Just like #15 blade is used to adjust the cut if tissue is still attached after initial incision. [0050] Prototype B always need #15 Blade to make crestal incision. [0051] Prototype A and Prototype B may not work ideally if have severe bone loss and/or irregular bone anatomy.

[0052] The present disclosure is described by referring figures. FIG. 7, FIG. 8 and FIG. 9 depict exploded views of the elements that comprise device for crestal and vertical incisions in Prototype C. FIG. 7 depicts view of Prototype C with blade facing down. Component 701 is quarter-round blade. Component 704 is thumb rest. Component 705 is index finger rest. Component 706 is incision start point. Component 707 is incision end point.

[0053] FIG. 8 depicts view of Prototype C with blade facing up. Component 801 is quarter-round blade. Component 804 is thumb rest. Component 805 is index finger rest.

[0054] FIG. 9 depicts side view of Prototype C with blade pointed to the left side. Component 901 is quarter-round blade. Component 904 is thumb rest. To make incision, place index finger on index finger rest and thumb on thumb rest. With significant apical pressure start incision with 90-degree angle at blade point 706 until feel crest of bone. Then, firmly but slowly roll till reaching desired length of incision, or maximum length to point, 707. Prototype C can be used in crestal as well as vertical incisions.

[0055] Prototype C PROS vs #15 Blade [0056] More ergonomic design [0057] Easier incision [0058] Less procedural time [0059] Less blood loss [0060] More clear cut (single continuous cut instead of increments by #15 blade) [0061] Faster longer incision (then incremental incision by #15 blade) [0062] More accurate cut (single continuous cut instead of increments by #15 blade)

[0063] These Prototypes A, B, and C very similar to punch biopsy devices in terms of simple use and multiple prefabricated sizes. However, these prototypes are more accurate then punch biopsy devices, because bone visibility is possible. These devices may become valuable due to multiple factors. Their simple use and design may just make them very popular for general dentists, periodontists and oral surgeons.
