“…Three-dimensional evaluation of the alveolar bone, prior to orthodontic tooth movement, in cleft-adjacent teeth would help preserve bone, define timing for the secondary alveolar bone graft, and lower risk of causing dehiscence in susceptible areas (Garib et al, 2006, Rungcharassaeng et al, 2007, Garib et al, 2012). A few studies have looked into alveolar bone morphology, using CBCT, in patients with ULCLP (Ercan et al, 2015, Buyuk et al, 2016, Pan et al, 2018, Parveen et al, 2018). However, they either did not cover all the features of alveolar bone morphology (Buyuk et al, 2016, Parveen et al, 2018) or teeth adjacent to the cleft area (Ercan et al, 2015, Pan et al, 2018).…”

“…Periodontal status of the teeth adjacent to the cleft is of great concern for orthodontists (Woods et al, 2018). As part of a multidisciplinary rehabilitation protocol of CLP, orthodontic treatment comprises of intricate tooth movement and biomechanics (Brägger et al, 1990, Pan et al, 2018, Parveen et al, 2018). The evaluation of alveolar bone morphology is necessary to avoid iatrogenic periodontal complications and to define the periodontal consequence of tooth movement prior to secondary alveolar bone graft (Garib et al, 2006, Rungcharassaeng et al, 2007, Garib et al, 2012).…”

“…A few studies have investigated 3-dimensional characteristics of periodontal alveolar bone around the teeth adjacent to the cleft (Garib et al, 2012, Buyuk et al, 2016, Pan et al, 2018, Parveen et al, 2018). Therefore, the aim of the present study was to assess the alveolar bone morphology on different surfaces of the teeth in patients with unilateral cleft lip and palate (ULCLP) using CBCT.…”

Objective: To evaluate the bony support around the teeth adjacent to the unilateral cleft lip and palate (ULCLP) using cone-beam computed tomography. Methods and Materials: Cone-beam computed tomographies of 48 cleft-adjacent teeth (28 anterior and 20 posterior to the cleft) and 48 noncleft control teeth were evaluated. The alveolar bone thickness at 3 and 6 mm apical to the cement–enamel junction (CEJ), the distance between the alveolar crest and CEJ (Alv-CEJ), and the presence of fenestration were assessed in buccal, palatal, and proximal surfaces. Results: The alveolar bone on the buccal and palatal sides of the teeth anterior to the cleft was significantly thinner than the noncleft teeth (all P < .05). The Alv-CEJ was significantly greater on the buccal and distal surfaces of the teeth anterior to the cleft ( P < .001 and P = .010, respectively) and on the palatal and mesial surfaces of the teeth posterior to the cleft ( P = .024 and P = .003, respectively) when compared to the noncleft teeth. The frequency of reduced alveolar bone height (>2 mm) was higher than noncleft side for buccal and distal sides of the teeth anterior to the cleft ( P = .016 and .006, respectively) and the buccal and mesial sides of the teeth posterior to the cleft ( P = .008 and <.001, respectively). The teeth anterior to the cleft had a higher prevalence of fenestration ( P = .004). Conclusion: Reduced alveolar bone height is more common in the cleft side compared to the control side. The teeth anterior to the ULCLP have thinner alveolar bone support and higher frequency of fenestration.

“…The ABTs on the labial, lingual, and distal surfaces were measured on both sides (Figure 1G-J). The distal ABT on the noncleft side was measured using the horizontal distance between U1 and lateral incisor according to the coronal section line (Pan et al, 2018).…”

Objectives: To evaluate the tooth lengths, crown to root ratios (CRRs), and alveolar bone support (ABS) around cleft-adjacent maxillary central incisors (U1s) in patients with unilateral cleft lip and alveolus (UCLA) and to investigate the relationships between CRR and ABS. Design: This is a retrospective study. Setting: Cleft Lip and Palate Care Center of Shanghai Ninth People’s Hospital, Shanghai, China. Patients: Fifty-eight Chinese patients with UCLA. Main Outcome Measure: Cone beam computed tomography data from 58 nonsyndromic patients with UCLA (36 males, 22 females; mean age = 12.65 ± 3.64 years) were evaluated. Crown length and root length, alveolar bone thickness (ABT), and the distances between the cementoenamel junction and alveolar bone crest on 4 surfaces of cleft-adjacent U1 were measured and compared with those of noncleft side in the same patients. Crown to root ratio and frequency of dehiscence were calculated and comparisons were also made between cleft and noncleft sides. Regression analysis was performed to explore the association between CRR and ABS. Results: The CRR of cleft-adjacent U1 and alveolar bone crest heights (ACHs) on the 4 surfaces were significantly greater than those of noncleft side ( P < .01). A 3 mm labial, all lingual, and apico-distal ABTs decreased on the cleft side ( P < .01). A positive correlation was found between lingual ACH and CRR ( R = 0.316, P < .05), between the 3 mm ( R = 0.417, P < .05) and 6 mm labial ( R = 0.448, P < .05) ABT and CRR. A negative correlation was found between the 3 mm and 6 mm labial ABTs and the root length. Conclusions: It can be suggested that the CRR is related to ACH and ABT. The lingual ACH, the 3 mm, and 6 mm labial ABTs tend to increase with the increasing CRR.

BackgroundMesiodens usually lead to the malposition and abnormal morphology of maxillary central incisors.AimTo evaluate the detrimental effects of single unilaterally impacted mesiodens on the three‐dimensional positions and morphology of the maxillary central incisor using cone‐beam computed tomographic (CBCT) examinations.DesignA total of 321 patients aged 5–17 years with single unilaterally impacted mesiodens were included and divided into two groups: mixed dentition group (5–10 years) and early permanent dentition group (11–17 years). CBCT data for these patients were retrospectively analyzed to compare the inclination, rotation, angulation, and morphology of maxillary central incisors between the affected and contralateral control sides. The morphology, orientation, and spatial location of mesiodens were also assessed.ResultsCentral incisors on the affected side showed significant palatal crown inclination, shorter root, shorter tooth, and greater crown‐to‐root ratio in both groups, whereas significant mesial crown angulation was only observed in the mixed dentition group.ConclusionImpacted mesiodentes result in the displacement and impaired root development of central incisors, strongly suggesting timely clinical management of these abnormal teeth, such as the early removal of mesiodens and orthodontic treatments.

Evaluation of alveolar bone support around incisors in patients with unilateral cleft lip, alveolus, and palate in late mixed dentition using cone beam computed tomography

Abstract: Patients with UCLAP have reduced alveolar bone support around the cleft-adjacent U1, and the apico-labial ABT tends to decrease with increasing lingual tooth inclination; however, the correlation was weak.
