- Abstract
Background: Although arch stability has been studied in patients without a cleft, evidence for patients with a cleft is sparse. Therefore, we compared the dimensions and stability of dental arches in cleft lip and palate patients and those without a cleft. Methods: Forty participants, 20 with a complete unilateral cleft lip and palate and 20 non-cleft patients aged from 18 to 30 years, with anterior and/or posterior crossbite and receiving orthodontic treatment were evaluated retrospectively. Eighty gypsum casts were digitized using a laser model scanner casts for both groups made immediately after the orthodontic treatment was completed (T1). Also, for the Cleft Lip and Palate group, casts were obtained and digitized 1 year after implant-supported rehabilitation (T2) and for the Non-Cleft Lip and Palate group, 1 year after the conclusion of the orthodontic treatment (T2). The formula: Δ = T2-T1 evaluated the stability of dental arches for inter-canine distances (C-C′), inter-molar distances (M-M'), arch length (I-M), palate surface and volume. The dimensions of the dental arches were measured digitally. The independent t test was used for statistical analysis (α = 0.05). Results: A statistical difference was found in the stability of the groups for inter-canine (cleft area) measurement. At the times T1 and T2, a statistically significant difference was found in the arch length, surface and volume. Conclusions: This study concluded that in the Cleft Lip and Palate group, the maxillary dimensions were not stabilized after 1 year of orthodontic and prosthodontic treatment (mainly for the inter-canine linear measurement) and that the transverse arch dimensions were smaller compared with those of non-cleft patients.
