“…The difference between the maxillary central incisors was reported to be in excess of 1 mm in patients with unilateral CLP, but the difference was not considered clinically significant. 33 In our study, the difference between distances without correlation of symmetry also varied by about 1 mm (Supplementary Digital Content, Table 4, http:// links.lww.com/SCS/C342) according to the side of the cleft.…”

Arch asymmetry in cleft patients is a current problem that interdisciplinary treatment aims to solve. This research proposed to analyze the final rehabilitation, according to the arch symmetry of these patients. Thirty-five patients aged between 18 and 30 years, rehabilitated with a fixed partial denture or implants in the cleft area. The analysis was performed using digitalized dental casts with a laser model scanner (R700TM; 3Shape A/S, Holmens Kanal 7, 1060, Copenhagen/Denmark), analyzed with a Vectra Analysis Module software program (VECTRA H1; Canfield Scientific, 4 Wood Hollow Road, Parsippany, NJ 07054). Three linear measurements were evaluated, incisal-canine, canine-molar, and incisalmolar distance. The Student t test was applied to test the significance (P ¼ 0.05) of an observed sample by correlation coefficient test (r-value). Female patients showed a significant correlation in arch symmetry. According to the rehabilitation treatment, patients who received implants showed a high correlation and significant symmetry at all maxillary distances. Finally, according to the cleft side in the maxillary dimensions, even though the majority of patients had clefts on the left side, only patients with a cleft on the right side showed symmetry in this area. Patients rehabilitated with implants in the cleft area showed a more symmetrical maxillary arch than those restored with fixed partial dentures.

“…On the other hand, achieving ideal positioning of the teeth (crown and root) and obtaining a stable and functional occlusion are other important goals during orthodontic treatment (Lee et al, 2018). In this way, several studies have been carried out to investigate tooth morphologies and arch sizes in patients with CLP (Foster and Lavelle, 1971;Eerens et al, 2001;Enemark et al, 2001;Dindaroglu et al, 2019). In addition, achievement of ideal root positions is highly important for the optimum restorative treatment, periodontal health, and functionality of occlusion.…”

“…Adequate mesiodistal root angulation is indispensable for ideal occlusion and proper articulation (Andrews, 1972). Muscular imbalances, differences in dental morphology, deformity-related asymmetrical forces, and the amount of bone have been thought to effect mesiodistal angulations in individuals with UCLP (Dindaroglu et al, 2019). Determination of axial tooth inclinations before treatment allows accurate bracket positioning and therefore, achievement of ideal proximal and occlusal contacts after the treatment.…”

“…Although there are several studies (Foster and Lavelle, 1971;Lewis et al, 2008;Camporesi et al, 2010;Zhou et al, 2013;Dindaroglu et al, 2019) in the literature that examined crown anomalies and arch dimensions seen in individuals with CLP, to our knowledge, no study in the literature investigated mesiodistal angulation symmetry in patients with UCLP in comparison to class I patients. The purpose of this study was to assess the mesiodistal angulation symmetry in patients with UCLP and make a comparison to the control group.…”

Objective: To assess the symmetry of the mesiodistal angulations of maxillary and mandibular teeth in patients with unilateral cleft lip and palate (UCLP) and compare with the class I control group without cleft lip and palate (CLP). Design: A retrospective study. Setting: University department. Patients, Participants: The panoramic radiographs of 45 orthodontically untreated individuals with nonsyndromic UCLP (mean age 14.13 ± 0.75 years) and 45 skeletal class I individuals without CLP (mean age 14.01 ± 0.74 years). Interventions: The line passing through the most superior points of the condyles was taken as the reference. The angle between the long axes of the maxillary and mandibular teeth and reference line was measured digitally. With the purpose of determining condylar symmetry, mandibular asymmetry index measurements were utilized. Independent samples t test and paired samples t test were used for the statistical analyses. Main Outcome Measure(s): The mesiodistal angulation of the maxillary and mandibular teeth in patients with UCLP was measured. The differences between the contralateral sides were determined and compared to class I individuals without CLP. Results: No statistically significant difference was found among the condylar asymmetry in both groups ( P > .05).The significant differences between the cleft and noncleft sides in the UCLP group was observed in the maxillary central, canine, first premolar and second molar teeth ( P < .001, P = .002, P = .013, P = .012, respectively). The mean differences were found to be higher in the central and lateral incisors, canines and first premolars in the UCLP group ( P < .001, P = .006, P = .001, respectively). Conclusions: Although the cleft-side maxillary central incisors tipped in a distal direction in patients with UCLP, the canine and first premolar showed more inclinations toward the mesial direction.

“…33 No mesiodistal tooth size asymmetries were found for the maxillary central incisors in this study, corroborating the study by Santos et al 34 However, other previous studies have reported smaller anterior tooth size on the cleft side in UCLP, compared to noncleft side. [35][36][37] Tooth size and shape differences of the cleft side central incisors may be associated with the dental anomalies pattern. 38 Clinician should observe each case individually, and an augmentation of the cleft-side central incisor can be recommended in case of clinically relevant asymmetries.…”

Objective: To compare dental positional and gingival parameters of maxillary anterior teeth in unilateral cleft lip and palate (UCLP) after orthodontic treatment with canine substitution due to lateral incisor agenesis. Methods: This split-mouth study comprised 57 subjects with UCLP (31 male, 26 female) and agenesis of maxillary lateral incisor at the cleft side, from a single center. Canine substitution was completed after the secondary alveolar bone graft. Dental models were taken between 2 to 6 months after debonding (mean age: 20.4 years). The following variables were measured in the maxillary anterior teeth: crown height, width, proportion, and symmetry, as well as steps between incisal edges, gingival margins, tooth mesiodistal angulation and labiolingual inclination. Paired t-tests with Bonferroni post-hoc correction was used for comparisons between cleft and non-cleft sides (p<0.05). Results: At the cleft side, canines replacing missing lateral incisors had a higher crown height (0.77mm) and an increased width (0.67mm), and first premolars showed a shorter crown height (1.39mm). Asymmetries were observed in the gingival level of central and lateral incisors, with a greater clinical crown at the cleft side (0.61 and 0.81mm, respectively). Cleft side central incisors were more upright than their contralaterals (2.12º). Conclusions: Maxillary anterior teeth demonstrated positional, size and gingival height differences between cleft and non-cleft side after space closure of maxillary lateral incisor agenesis. Slight asymmetries in tooth position and gingival margin in the maxillary anterior teeth should be expected after orthodontic treatment in UCLP patients.
