BackgroundThe bone graft for the alveolar cleft has been accepted as one of the essential treatments for cleft lip patients. Precise preoperative measurement of the architecture and size of the bone defect in alveolar cleft has been considered helpful for increasing the success rate of bone grafting because those features may vary with the cleft type. Recently, some studies have reported on the usefulness of three-dimensional (3D) computed tomography (CT) assessment of alveolar bone defect; however, no study on the possible implication of the cleft type on the difference between the presumed and actual value has been conducted yet. We aimed to evaluate the clinical predictability of such measurement using 3D CT assessment according to the cleft type.MethodsThe study consisted of 47 pediatric patients. The subjects were divided according to the cleft type. CT was performed before the graft operation and assessed using image analysis software. The statistical significance of the difference between the preoperative estimation and intraoperative measurement was analyzed.ResultsThe difference between the preoperative and intraoperative values were -0.1±0.3 cm3 (P=0.084). There was no significant intergroup difference, but the groups with a cleft palate showed a significant difference of -0.2±0.3 cm3 (P<0.05).ConclusionsAssessment of the alveolar cleft volume using 3D CT scan data and image analysis software can help in selecting the optimal graft procedure and extracting the correct volume of cancellous bone for grafting. Considering the cleft type, it would be helpful to extract an additional volume of 0.2 cm3 in the presence of a cleft palate.

“…Different imaging methods have been used for the assessment of bone grafts in the alveolar region, including radiographic methods [31–33], computed tomography (CT) [34, 35], and ultrasound (R. B. Lawson and M. L. Jones 1998). Rosenstein et al [36] showed that the overall assessment of alveolar bone grafts using radiographic images was equivalent to that using CT.…”

“…Rosenstein et al [36] showed that the overall assessment of alveolar bone grafts using radiographic images was equivalent to that using CT. However, evidence suggests that CT may be a superior method to the use of conventional radiographs, as the 3-dimensional image can clearly identify bony bridge formation after grafting and the amount of bone at the receptor site, according to the bone cross-sectional image preview in the buccal-palatal direction [34, 35]. For this reason, in our work, we have evaluated CBCT images performed immediately after and after 8 months (± 21 days) from the operation.…”

Introduction Orofacial clefts are congenital malformations characterized by an incomplete shaping of structures that separate the nasal from the oral cavity and can affect the right, left, or both sides. The aim of the present study is to assess, with clinical, radiographical, and histological evaluations, the efficacy of piezoelectric devices compared to traditional rotating instruments in the bone harvesting in patients with history of cleft. Materials and Methods We have conducted a retrospective analysis on 20 patients with a history of orofacial clefts that were operated on from February 2014 to June 2017. The patients were divided into two groups: Group R in which bone graft was harvested using a burr and Group P in which the bone graft was obtained by a piezoelectric device. After a healing period of 8 months from the grafting procedure, clinical and radiographic evaluations were performed. Results and Discussion The use of the piezoelectric devices in bone harvesting allows a slight improvement in the final volume. This supports a faster integration into the receiving site. Conclusions The use of piezoelectric device in patients with history of orofacial cleft that needed bone graft represents a method to be taken into consideration because it has interesting advantages.

Alveolar cleft is a tornado-shaped bone defect in the maxillary arch. The treatment goals for alveolar cleft are stabilization and provision of bone continuity to the maxillary arch, permitting support for tooth eruption, eliminating oronasal fistulas, providing an improved esthetic result, and improving speech. Treatment protocols vary in terms of the operative time, surgical techniques, and graft materials. Early approaches including boneless bone grafting (gingivoperiosteoplasty) and primary bone graft fell into disfavor because they impaired facial growth, and they remain controversial. Secondary bone graft (SBG) is not the most perfect method, but long-term follow-up has shown that the graft is absorbed to a lesser extent, does not impede facial growth, and supports other teeth. Accordingly, SBG in the mixed dentition phase (6–11 years) has become the preferred method of treatment. The most commonly used graft material is cancellous bone from the iliac crest. Recently, many researchers have investigated the use of allogeneic bone, artificial bone, and recombinant human bone morphogenetic protein, along with growth factors because of their ability to decrease donor-site morbidity. Further investigations of bone substitutes and additives will continue to be needed to increase their effectiveness and to reduce complications.
