Maine’s rules come from 32 M.R.S. ch. 143 and Board of Dental Practice rules. Check the legislation tracker for pending changes.
1. CPOD status
Tier: Permissive No section of 32 M.R.S. ch. 143 requires dentist ownership. Two provisions point the other way:- 32 M.R.S. § 18371(1)(A) authorizes a dentist to perform dentistry for compensation “paid… directly or indirectly to the person or to any other person or agency who is a proprietor of a place where dental operations, oral surgery or dental services are performed.” The language contemplates a proprietor other than the treating dentist.
- 32 M.R.S. § 18304(2)(C): a “manager, proprietor, operator or conductor of a place for performing dental operations” may not employ an unlicensed person to perform dentistry. By negative implication, a non-dentist proprietor may employ licensed dentists.
2. Other professions
This page covers dentistry only. Medicine, optometry, veterinary practice, and other professions are governed by different statutes and boards, even within the same state. For medical-practice sources, use the MSO-PC Wiki.3. Professional entity forms
Dentistry is a mandatory-PC profession in Maine: a dentist forming a corporation “shall incorporate as a professional corporation” under the Maine Professional Service Corporation Act, 13 M.R.S. ch. 22-A (§ 723(7)(A) lists dentists; § 731(1) makes coverage mandatory). The chapter also defines professional LLCs and professional LLPs (§ 723(5)–(6)). Shares may be issued only to qualified licensed persons (§ 741(1)). Specified dental professionals may hold minority interests. Under 13 M.R.S. § 732(4), a denturist or independent practice dental hygienist may hold shares in an incorporated dental practice. Their combined interest must remain smaller than the dentists’ interest. Also confirm before filing:- Naming rules, designator requirements, and any limits tied to licensed owners’ names; several states regulate dental trade names separately
- Board pre-approval or certificates, whether the dental board must act before (or after) the secretary of state will file
- Officer and director licensure, including states that restrict these roles as well as ownership to licensees
4. Fee structure
No Maine statute located for this page bans percentage-of-collections management fees. Because ch. 143 contains no ownership restriction, generally applicable law carries more weight in the fee analysis than CPOD doctrine. The § 18304(2)(B) trade-name rule separately makes branding relevant. Verify both the economics and public-facing name with Maine counsel. For the MSA, test whether a percentage-of-collections fee is permitted under the state’s dental, fee-splitting, referral, tax, and contract rules. Several states expressly restrict revenue-linked dental management fees, and the Aspen Dental settlements imposed related party-specific terms. Flat and cost-plus formulas are not automatic safe harbors; the services, calculation, amount, control rights, and actual payments still matter. See Fee-splitting rules and Set the management fee.5. Noncompetes
No dental-specific noncompete statute was identified in this research; Maine noncompetes are governed by general state employment law. Verify current Maine law with counsel before including one. Federal noncompete policy changed substantially in 2025 and 2026. The FTC’s Non-Compete Rule was vacated, the agency dismissed its appeals in September 2025, and the rule was removed from 16 C.F.R. pt. 910 effective February 12, 2026. State law remains central. Dental enforcement resolutions in New York and California have also restricted noncompetes for the settling parties as a corporate-practice remedy. Verify the current rule, worker, agreement type, transaction context, effective date, and remedy in this state. See the legislation tracker.6. DSO-specific law and registration
None. No registration, disclosure, or regulation of dental support organizations or dental management agreements appears in 32 M.R.S. ch. 143, based on the October 2025 official compilation reviewed for this page. The tables of contents for the Board rules (02-313 C.M.R., including ch. 12, “Practice Requirements”) show no ownership or management chapter. Verify the rule text with counsel.7. Death and transition window
Under 13 M.R.S. § 732(5), the legal guardian or personal representative of a deceased or incapacitated dentist may contract with another dentist to continue the practice for up to 48 months or until sale, whichever occurs first. PL 2025, c. 121, § 1 amended the period; the prior period was not verified for this page.8. Practical structuring notes
Check citations before relying on older Maine summaries. PL 2015, c. 429 recodified the dental practice act in 2016, moving it from 32 M.R.S. ch. 16 to ch. 143. Pre-2016 citations such as § 1081 are obsolete, and the statement that “a corporation may not practice dentistry” in older bill text does not appear in current ch. 143. For a multi-site group, also address the trade-name rule in § 18304(2)(B). Maine joined the Dentist and Dental Hygienist Compact at 32 M.R.S. §§ 18431–18445 in 2023–24, which may help with multi-state licensure for recruited dentists.9. Verification checklist
