Background California Senate Bill 630 (SB630) enacted statutorily mandated health plan coverage for orthodontic care of patients with cleft palate and craniofacial anomalies in 2009, which was effective from July 1, 2010. In this qualitative analysis, third-party compliance with SB630 in a university-based cleft and craniofacial orthodontic program is evaluated. Methods Privately insured patients that experienced a coverage delay or denial of orthodontic treatment for cleft lip and palate in the University of California, San Francisco Cleft and Craniofacial Orthodontic Program between July 1, 2010 and October 28, 2020 were identified. A thematic analysis of reasons for delay or denial was conducted. Results Nearly three quarters of patients experienced coverage delay and/or denials. The most common reason given was that services were not covered. Conclusions Despite state-mandated coverage, inappropriate denials of orthodontic care for patients with cleft lip and palate by private insurers persist in California.
Objectives: The objective of this study was to utilize digital models and cone-beam computed tomography (CBCT) radiographs to quantify the skeletal and dentoalveolar maxillary expansion in Phase I orthodontic treatment using clear aligner therapy. Material and Methods: Fifty-four patients (22 females and 32 males) had measurements taken on both the pre-treatment and post-treatment intraoral scans from the mesiolingual cusps of the maxillary permanent first molars and the cusp tips of the maxillary primary canines to perform model analysis of dentoalveolar expansion. The planned amount of expansion in the ClinCheck® setup was compared to the actual expansion. Twenty-nine patients (14 females and 15 males) out of 54 patients had both pre-treatment and post-treatment CBCT scans, which also allowed us to perform measurements between maxillary permanent first molars and between maxillary primary canines using CBCT data. Results: Posterior expansion of 2.40 mm between maxillary permanent first molars and anterior expansion of 4.01 mm between maxillary primary canines was observed. A comparison with ClinCheck® showed percent yields of 51.15% for posterior expansion and 64.73% for anterior expansion. CBCT analysis displayed posterior expansion of 1.89 mm between the first molars, 1.87 mm between first molar cementoenamel junctions (CEJs), an angle change of −1.16° (buccal tipping) between first molars, anterior expansion of 3.64 mm between the primary canines, 1.78 mm between primary canine CEJs, and an angle change of 24.73° (facial tipping) between the primary canines. Conclusion: Our study highlights the potential capability of Phase I orthodontic treatment with clear aligners and shows that maxillary expansion does occur with the use of clear aligners.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
