Item 1.  Security and Issuer

    This Schedule 13D ("Schedule") relates to shares of common stock,
with par value $0.0001 (the "Common Stock"), of Crdentia Corp. (the
"Issuer").  The principal executive office of the Issuer is 5001 LBJ
Freeway, Suite 850, Dallas, TX 75244.

Item 2.  Identity and Background

    This Schedule is filed on behalf of MedCap Partners L.P. ("MedCap"),
MedCap Management & Research LLC ("MMR") and C. Fred Toney ("Toney"),
each of whose principal business office address is 500 Third Street,
Suite 535, San Francisco, CA 94107.

    MedCap is an investment limited partnership, whose general partner is
MMR.  MMR is an investment adviser registered under the laws of the State
of California.  Toney is MMR's sole managing member. MMR is also the
general partner and investment manager of MedCap Master Fund, L.P., an
investment limited partnership ("MedCap Master").  MedCap Master is a
"master fund" and contains substantially all of the assets of a "feeder
fund," MedCap Partners Offshore, Ltd. ("MedCap Offshore")."

    None of MedCap, MMR nor Toney has, during the past five years, been
convicted in any criminal proceeding (excluding traffic violations or
similar misdemeanors).

    None of MedCap, MMR nor Toney has, during the past five years, been a
party to a civil proceeding of a judicial or administrative body of
competent jurisdiction, as a result of which any of them became or is
subject to a judgment, decree or final order enjoining future violations
of, or prohibiting or mandating activities subject to, federal or state
securities laws or finding any violation with respect to such laws.

    MedCap is a Delaware limited partnership, MMR is a Delaware limited
liability company and Toney is a United States citizen.

Item 3. Source and Amount of Funds or Other Consideration

    The aggregate purchase price for the 2,853,333 shares of the Issuer's
Common Stock acquired by Toney in the PIPE transactions described under
Item 5(c) below (the "Toney Shares") was approximately $1,550,000. The
aggregate purchase price for the Toney Shares was paid by Toney using
personal funds.


CUSIP 225235308                 SCHEDULE 13D                Page 6 of 16


Item 4. Purpose of Transaction

    The Toney Shares are held by Toney for investment purposes.

    The agreement of limited partnership of MedCap provides MMR with
discretion to cause MedCap to make payments upon a withdrawal by a
limited partner in cash or in securities, or a combination of cash and
securities, or to segregate a portion of MedCap's assets equal to the
amount payable to the withdrawing limited partner and sell those assets
for the account of the withdrawn limited partner.  Limited partners of
MedCap have the right, upon written request, to receive a distribution of
the segregated assets.  Effective September 30, 2006, MedCap segregated
some of the Issuer's Common Stock beneficially owned by MedCap into a
separate account for the benefit of some of MedCap's former limited
partners who have withdrawn from MedCap.  On December 18, 2006 and
December 29, 2006, respectively, MedCap distributed from the segregated
account 252,892 shares of Common Stock and 440,153 shares of Common Stock
to certain of MedCap's former limited partners, leaving, after
distribution, 3,001 shares of Common Stock in the segregated account.
MMR, as MedCap's general partner, and Toney, as MMR's sole managing
member, continue to have voting and dispositive control over the
remaining shares of Common Stock in the segregated account.  MMR intends
to cause MedCap to sell the remaining segregated Common Stock in an
orderly fashion and distribute the proceeds to the withdrawn limited
partners or to distribute in-kind the segregated Common Stock to its
withdrawn limited partners in the near future.

    As previously disclosed on the Issuer's Current Report on Form 8-K
filed with the Securities and Exchange Commission (the "Commission") on
September 26, 2006 (and on the reporting persons' prior Schedule 13D/A
(Amendment No. 8), filed with the Commission on November 3, 2006), the
Issuer, iVOW Acquisition Corp., a Delaware corporation and wholly-owned
subsidiary of the Issuer ("Merger Sub") and iVOW, Inc., a Delaware
corporation ("iVOW"), have entered into an Agreement and Plan of Merger,
dated as of September 20, 2006 (the "Merger Agreement"), pursuant to
which Merger Sub will merge with and into iVOW, with iVOW surviving as a
wholly-owned subsidiary of the Issuer (the "Merger").   At the effective
time of the Merger, all shares of iVOW common stock issued and
outstanding immediately prior to the effective time will be converted
automatically into the right to receive, in the aggregate, approximately
$3.5 million in shares of the Issuer's Common Stock (based on the average
of the closing sale prices for Issuer's Common Stock for each of the 20
consecutive trading days ending the second complete trading day prior to
the effective time of the Merger, as reported on the OTC Bulletin Board),
subject to reduction based on the iVOW bank and financing debt assumed by
the Issuer, the value of any uncollected accounts receivable at the
effective time and the value of any iVOW warrants assumed by the Issuer.


CUSIP 225235308                 SCHEDULE 13D                Page 7 of 16


    Toney and MMR have beneficial ownership (through MedCap and MedCap
Master) of approximately 16.2% of iVOW's outstanding common stock, based
on the number of shares of iVOW's outstanding common stock listed in
iVOW's Current Report on Form 8-K, filed with the Commission on September
22, 2006 (3,474,865 shares).  Toney was also a member of iVOW's Board of
Directors when the Merger Agreement was approved by the iVOW Board, but
he voluntarily resigned from that position effective as of September 20,
2006.  Toney remains a member of the Issuer's Board of Directors.

    In connection with the execution of the Merger Agreement, each of the
Issuer and iVOW have entered into separate voting agreements (the "Voting
Agreements") with MedCap and MedCap Master, each dated September 20,
2006, pursuant to which MedCap and MedCap Master have agreed, among other
things, to vote all of the shares of the Issuer's Common Stock and the
common stock of iVOW held by them in favor of the adoption of the Merger
Agreement. MedCap and MedCap Master have also agreed under the Voting
Agreements not to dispose of shares of the Issuer's Common Stock or the
common stock of iVOW, except as permitted thereunder.

    Depending on market conditions and other factors, the reporting
persons may, at any time or from time to time, acquire additional
securities of the Issuer, or alternatively, may (if and to the extent
permitted under the Voting Agreements) dispose of some or all of the
securities of the Issuer beneficially owned by them (including but not
limited to the aforementioned segregated shares of Common Stock).

    Except as described herein, the reporting persons do not currently
have any plans or proposals that relate to or would result in any of the
following:

    (a) The acquisition by any person of additional securities of the
Issuer, or the disposition of securities of the Issuer;

    (b) An extraordinary corporate transaction, such as a merger,
reorganization, or liquidation, involving the Issuer or any of its
subsidiaries;

    (c) A sale or transfer of a material amount of assets of the Issuer
or any of its subsidiaries;

    (d) Any change in the present board of directors or management of the
Issuer, including any plans or proposals to change the number or term of
directors or to fill any existing vacancies on the board;

    (e) Any material change in the present capitalization or dividend
policy of the Issuer;

    (f) Any other material change in the Issuer's business or corporate
structure;


CUSIP 225235308                 SCHEDULE 13D                Page 8 of 16


    (g) Changes in the Issuer's charter, bylaws or instruments
corresponding thereto or other actions which may impede the acquisition
of control of the Issuer by any person;

    (h) Causing a class of securities of the Issuer to be delisted from a
national securities exchange or to cease to be authorized to be quoted in
an inter-dealer quotation system of a registered national securities
association;

    (i) A class of equity securities of the issuer becoming eligible for
termination of registration pursuant to Section 12(g)(4) of the Act; or

    (j) Any action similar to those enumerated above.

Item 5. Interest in Securities of the Issuer

    (a) As noted above, MedCap beneficially owns 8,521,098 shares of the
        Issuer's Common Stock.  The percentage of common stock
        beneficially owned by MedCap for the purposes of this Schedule is
        50.3%.

        In addition to the securities beneficially owned through MedCap,
        MMR and Toney beneficially own 177,250 shares of the Issuer's
        Common Stock through MedCap Master. MedCap Master is a "master
        fund" and contains substantially all of the assets of a "feeder
        fund," MedCap Partners Offshore, Ltd. ("MedCap Offshore").

        Toney holds the Toney Shares (2,583,333 shares in total)
        personally.

        MMR, as general partner and investment manager of MedCap and
        MedCap Master, and Toney, as the sole managing member of MMR, may
        be deemed to beneficially own the shares owned by MedCap and
        MedCap Master in that they may be deemed to have the power to
        direct the voting or disposition of the shares.  Neither the
        filing of this Schedule nor any of its contents shall be deemed
        to constitute an admission that either MMR or Toney is, for any
        other purpose, the beneficial owner of any such securities, and
        MMR and Toney disclaim beneficial ownership as to such securities
        except to the extent of their respective pecuniary interests
        therein.  The percentage of Common Stock beneficially owned by
        MMR for the purposes of this Schedule is 51.4% and by Toney for
        the purposes of this Schedule is 66.7%.

        The calculation of percentage of beneficial ownership in Item 11
        of pages 2, 3 and 4 was derived from the Issuer's Form 10-QSB
        Quarterly Report Under Section 13 or 15(d) of the Securities
        Exchange Act of 1934, filed with the Commission on November 14,
        2006, in which the Issuer stated that the number of shares of its
        Common Stock outstanding as of November 9, 2006 was 14,344,230
        shares.


CUSIP 225235308                 SCHEDULE 13D                Page 9 of 16


        The foregoing amounts do not include shares of the Issuer's
        Common Stock issuable in respect of shares of the common stock of
        iVOW outstanding at the effective time of the Merger (including
        shares of iVOW common stock held by the reporting persons).

    (b) Reference is made hereby to Items 7 to 10 of pages 2, 3 and 4 of
        this Schedule, which Items are incorporated herein by reference.

    (c) On January 25, 2007, Toney purchased 950,000 shares of the
        Issuer's common stock for his personal account in a PIPE
        transaction for $0.60 per share.

        On February 6, 2007, Toney purchased 1,633,333 shares of the
        Issuer's common stock for his personal account in a PIPE
        transaction for $0.60 per share.

        Effective February 1, 2007, certain limited partners who had
        previously withdrawn from MedCap (and who had received pro rata
        in-kind distributions of the Issuer's common stock in connection
        with their prior withdrawal) contributed 281,843 shares of the
        Issuer's common stock to MedCap in exchange for new limited
        partnership interests in MedCap.

    (d) Not applicable.

    (e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with
Respect to Securities of the Issuer

    MedCap is a party to an Amended and Restated Registration Rights
Agreement entitling it to registration rights with respect to Common
Stock issued upon conversion of its shares of Series A Preferred Stock,
Series B-1 Preferred Stock and Series C Preferred Stock, including any
Series B-1 Preferred or Series C Preferred issued upon exercise of
certain warrants.

    MedCap and the Issuer are also parties to the Letter Agreement, as
amended by the Letter Agreement Amendment, which amends in part the
Amended and Restated Registration Rights Agreement.  Under the Letter
Agreement, the Issuer agrees to register for resale (i) all of the shares
of Common Stock and the Common Stock that can be acquired upon the
conversion of the Series C Preferred Stock that are held by MedCap and
(ii) shares of Common Stock underlying all of the warrants that MedCap
holds to acquire the Issuer's preferred stock; provided that, the Issuer
is not required to register for resale Common Stock underlying the
warrants unless such shares can be registered at the time that the shares
of Common Stock listed in item (i) are registered for resale.


CUSIP 225235308                 SCHEDULE 13D                Page 10 of 16


    MedCap was a party to two Secured Promissory Notes issued by the
Issuer, Baker Anderson Christie, Inc., Nurses Network, Inc., New Age

Care Pros Staffing, Inc., HIP Holding, Inc., Health Industry
Professionals, L.L.C., Travmed USA, Inc., Prime Staff, LP, Mint Medical

Issuer obtained a $500,000 loan from MedCap on November 15, 2005 and a
$1,500,000 loan from MedCap on November 18, 2005 to fund working capital
needs.  No equity securities and no securities exercisable, convertible
or exchangeable for equity securities were issued in connection with the
loans which were evidenced by the Secured Promissory Notes.  In
connection with the loans, MedCap, the Issuer and the Issuer's
subsidiaries were parties to an Amended and Restated Security Agreement
pursuant to which MedCap was granted a subordinate security interest in
all of the assets and property of the Issuer and the Issuer's
subsidiaries.  The Amended and Restated Security Agreement imposes
various restrictions on the activities of the Iasuer and the Issuer's
subsidiaries and includes events of default (with grace periods, as
applicable).

    MedCap and the Issuer were parties to a Securities Purchase Agreement
dated as December 30, 2005 pursuant to which the Issuer issued 335,370
shares of its common stock to MedCap in consideration for the
cancellation of the principal and all accrued interest under the Secured
Promissory Notes.  The shares were sold in a private transaction at a
price of $6.00 per share. In connection with the Securities Purchase
Agreement, the Issuer and MedCap entered into a Registration Rights
Agreement pursuant to which the Issuer agreed to register for resale on a
registration statement the shares acquired by MedCap under the Securities
Purchase Agreement.

    MedCap and the Issuer are parties to a Subscription Agreement dated
March 3, 2006, pursuant to which the Issuer sold 25,000 shares of its
Common Stock to MedCap at a price of $8.00 per share in a private
transaction.

private transaction.

    MedCap and the Issuer are parties to  Subscription Agreement dated
