“…Therefore, analyzing palatal morphology before, during, and at the end of the treatment becomes essential for a good clinical prognosis. Traditionally, palatal skeletal structures have been analyzed by two-dimensional (2D) methods, such as periapical, occlusal, and panoramic radiographs [7][8][9], omitting information about the volume of the alveolar bone defects. Indeed, a pre-surgical volume estimation can be useful to determine the anatomical boundaries of the alveolar bone defect; subsequently, volume assessments can appreciate the outcome of secondary alveolar bone grafting [7,10,11].…”

Cleft lip and/or palate (CL/P) are the most common craniofacial abnormalities. CL/P therapy involves also orthopedic and surgical treatments. In particular, the orthopedic treatment can help to align the cleft segments and facilitate surgery. Traditionally, facial and palatal structures have been analyzed by 2D methods, omitting information of volume bone defects. A pre-surgical volume estimation can be useful to determine the anatomical boundaries of the alveolar bone defect; subsequently, volume assessments can appreciate the outcome of secondary alveolar bone grafting. In the present study, we developed a 3D stereophotogrammetric technique for volume estimation of the dental arches of children with CL/P. The method was employed to assess the 3D changes occurring in the maxillary arch of unilateral CLP (UCLP) patients with the use of plates before the first year of life. We collected 96 palatal casts of 32 neonatal patients with UCLP. Palatal casts were obtained before orthopedic treatment, before cheiloplasty, and after cheiloplasty. Half patients were treated with an active plate, half with a passive one. Casts were marked with a set of landmarks, digitized using a stereophotogrammetric system, and then analyzed. Volumes of the greater and the minor alveolar segments were separately assessed, and compared with a 3-w repeated measures ANOVA. Method accuracy was assessed using objects of known size, while repeatability was evaluated using Student's t test and technical error of measurements. Volume estimates were accurate, without systematic errors; random errors were lower than 5% of the total variance. Significant effects of alveolar segment and time were observed (p<0.0001). Instead, no differences were found for the kind of plate. In conclusion, stereophotogrammetric systems can be a valid instrument to estimate palatal volumes of patients with CL/P during treatment, that can be followed up in a safe, rapid and non-invasive way.

Background: Alveolar clefts give rise to many aesthetic and functional problems among affected patients. Therefore, surgical adjustments of the bony defective anomalies are important. The authors performed secondary bone grafts and analyzed the effects particularly on the nasal septum and maxillary area (midface). Methods: The patients who had alveolar bone grafts were retrospectively reviewed with pre/postoperative 3-dimensional computed tomography; the measurements included distances between the anterior nasal spine (ANS) and the vertical midline, angles between the nasal septum and the transverse line, and angles between the floor of the pyriform aperture and the transverse line. Results: A total number of 23 patients were finally included in the study. The mean age of the patients was 9.7 ± 1.95 years (range, 7–14 years). The mean distance between the ANS and the vertical midline was 5.3 ± 4.70 mm/4.9 ± 4.15 mm pre/postoperatively, showing the mean paired difference of 0.4 ± 0.89 mm (P < 0.05). The mean angles between the nasal septum and the transverse line and between the floor of the pyriform aperture and the transverse line were 64.5 ± 14.69°/65.9 ± 13.73° and 21.7 ± 8.94°/11.5 ± 7.03° pre/postoperatively, showing the mean paired differences of −1.4 ± 2.78° and 10.1 ± 8.20°, respectively (both P < 0.05). Conclusion: The results suggest that secondary alveolar bone grafting has expanded effects on the adjacent midfacial structures.

Objective To analyse the maxillary arch dimensions of children aged 9 and 12 with unilateral cleft lip and palate (UCLP) who received orthodontic treatment and secondary alveolar bone grafting. Design This retrospective cohort study was performed on 30 patients with UCLP. Setting All patients were treated at the Cleft Lip and Palate Centre, which is part of the University Medical Centre Amsterdam and Academic Centre for Dentistry Amsterdam, the Netherlands. Patients/Participants Children with non-syndromic UCLP who received pre- and postsurgical orthodontics combined with secondary alveolar bone grafting between the ages of 9 and 12 years were included. Main Outcome Measures Maxillary arch dimensions were assessed on 60 digitised dental casts with measurements of the intermolar widths, interpremolar widths, arch perimeters, arch lengths, arch widths, and palatal depths. Results The results of a paired-samples t-test revealed a statistically significant increase ( P < .05) in intermolar width 1, intermolar width 3, interpremolar width 1, arch perimeter, and arch width between the ages of 9 (T0) and 12 (T1). Intermolar width 2 and the palatal depth decreased statistically significantly between T0 and T1. Conclusions Analysis of maxillary arch dimensions of children with UCLP indicates significant changes between 9 and 12 years of age. This suggests that orthodontic treatment and secondary alveolar bone grafting can be effective in improving maxillary arch dimensions. However, there is a need for collaborative research and data collection in order to provide sensible and evidence-based care to patients with cleft lip and palate.
