EXHIBIT 10.46

                                 CRDENTIA CORP.

                AMENDMENT TO RESTRICTED STOCK PURCHASE AGREEMENT

         This Amendment to Restricted Stock Purchase Agreement (this
"Amendment") is made as of August 3, 2004 by and among Crdentia Corp., a
Delaware corporation (the "Company") and Robert Oliver ("Stockholder").

                                    RECITALS

         A. On or about November 1, 2002, the Company and Stockholder executed a
certain Restricted Stock Purchase Agreement (the "Purchase Agreement") pursuant
to which the Company issued to Stockholder 100,000 shares of its Common Stock
(the "Shares") in exchange for providing services to the Company as a member of
its Board of Directors valued at $700.00.

         B. The Company and Stockholder desire to amend and correct certain
terms of the Purchase Agreement to reflect the parties' original intentions with
respect to the vesting of the Shares pursuant thereto.

         In consideration of the foregoing and the promises and covenants
contained herein and other good and valuable consideration the receipt of which
is hereby acknowledged, the parties hereto agree as follows. Any capitalized
terms not otherwise defined herein shall have the meanings given such terms in
the Notes:

         1. Amendment and Restatement of Section 5.6.

         Section 5.6 of the Agreement shall be amended and restated in its
entirety to read as follows:

                  "5.6     Corporate Transaction.

                           A. Immediately prior to the consummation of any of
                  the following stockholder-approved transactions (a "Corporate
                  Transaction"):

                                    (i) a merger or consolidation in which the
                  Corporation is not the surviving entity,

                                    (ii) the sale, transfer or other disposition
                  of all or substantially all of the Corporation's assets, or

                                    (iii) any transaction (other than an
                  issuance of shares by the Corporation for cash) in or by means
                  of which one or more persons acting in concert acquire, in the
                  aggregate, more than 50% of the outstanding shares of the
                  stock of the Corporation,

                                    the Repurchase Right shall automatically
                  lapse in its entirety.



                           B This Agreement shall not in any way affect the
                  right of the Corporation to adjust, reclassify, reorganize or
                  otherwise make changes in its capital or business structure or
                  to merge, consolidate, dissolve, liquidate or sell or transfer
                  all or any part of its business or assets."

         2. Effect of Amendment. Except as expressly amended, restated or
consented to in this Amendment, the Purchase Agreement shall continue in full
force and effect. In the event of any conflict between the terms of this
Amendment and the Purchase Agreement, the terms of this Amendment shall govern
and control.

         3. Governing Law. This Amendment shall be governed by and construed
under the laws of the State of California as applied to agreements among
California residents entered into and to be performed entirely within
California.

         4. Counterparts. This Amendment may be executed in any number of
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         5. Severability. If one or more provisions of this Amendment are held
to be unenforceable under applicable law, such provision shall be excluded from
this Amendment and the balance of the Amendment shall be interpreted as if such
provision were so excluded and shall be enforceable in accordance with its
terms.

         6. Entire Agreement. This Amendment, together with the Purchase
Agreement, constitutes the full and entire understanding and agreement between
the parties with regard to the subjects hereof and thereof.
