Re:  Lancer Orthodontics, Inc. - Registration Statement on Form S-8 for
     issuance of up to 450,000 Shares of Common Stock

Ladies and Gentlemen:

We have acted as counsel to Lancer Orthodontics, Inc., a California
corporation (the "Company"), in connection with the registration for
issuance of 450,000 shares of the Company's common stock, no par value per
share (the "Shares"), as described in the Company's Registration Statement
on Form S-8 (the "Registration Statement") filed with the Securities and
Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended (the "Securities Act"). The Shares may hereafter be issued pursuant
to the Lancer Orthodontics, Inc. 2000 Stock Incentive Plan (the "Plan").

In rendering the opinions expressed herein, we have examined (i) the
Company's Articles of Incorporation and all amendments thereto, (ii) the
Company's Bylaws, as amended, (iii) the applicable minutes of meetings or
consents in lieu of meetings of the Company's board of directors (the
"Board") and shareholders, and (iv) such other corporate records and
documents, certificates of corporate and public officials and statutes as we
have deemed necessary for the purposes of this opinion.  In such examination,
we have assumed the genuineness of all signatures, the authenticity of all
corporate records, documents and instruments submitted to us as originals,
the conformity to original documents of all documents submitted to us as
conformed, certified or photostatic copies thereof, the authenticity of the
originals of such photostatic, certified or conformed copies, and compliance
both in the past and in the future with the terms of the Plan by the Company
and its employees, officers, the Board and any committees appointed to
administer the Plan.

Based upon such examination and in reliance thereon, we are of the opinion
that upon the issuance of Shares in accordance with the terms and conditions
of the Plan, including receipt prior to issuance by the Company of the full
consideration for the Shares (which consideration shall be at least equal to
the par value thereof), the Shares will be validly issued, fully paid and
nonassessable shares of Common Stock. This opinion is not rendered with
respect to any laws other than the laws of the State of California and the
Federal law of the United States.

We consent to the filing of this opinion with the Commission as Exhibit 5.1
to the Registration Statement. In giving this consent, we do not thereby
admit that we are within the category of persons whose consent is required
under Section 7 of the Securities Act, the rules and regulations of the
Securities and Exchange Commission promulgated thereunder, or Item 509 of
Regulation S-K.

This opinion letter is rendered as of the date first written above and we
disclaim any obligation to advise you of facts, circumstances, events or
developments which hereafter may be brought to our attention and which may
alter, affect or modify the opinion expressed herein. Our opinion is expressly
limited to the matters set forth above and we render no opinion, whether by
implication or otherwise, as to any other matters relating to the Company or
the Shares.

Very truly yours,
