Fifty-six cleft sites were reviewed prior to alveolar bone grafting and subsequently evaluated for graft success using study models, periapical and occlusal radiographs from the Lancaster Cleft Palate Clinic. All patients in this sample had presurgical orthodontics to expand and align the maxillary arch prior to alveolar bone grafting. Ninety-five percent of the grafts were done using iliac crest, the remaining 5% were cranial grafts. The alveolar bone grafting technique used was as described by Boyne and Sands (1972, 1976). Cleft width was measured on a radiograph taken no more than 1 month preoperatively, following the completion of all orthodontic expansion. Cleft width was determined by inspection at its narrowest point. A distortion correction was attempted by determining the ratio of the radiographic width of the maxillary central incisor adjacent to the cleft compared with the actual width of this tooth measured on study models. The radiographic cleft width was then multiplied by this factor to approximate true cleft width. Alveolar contour was measured at least 6 months postoperatively using ratios of actual bone heights measured at the mesial, middle, and distal margin of the previous cleft compared with root length of adjacent teeth. This was to eliminate the radiographic distortion factors of foreshortening and elongation. Regression analysis was carried out to see if there was a correlation between preoperative cleft width and eventual success of the graft as measured on postsurgical radiographs. The success rate for achieving a bony bridge across the cleft was 91%. Mean alveolar crest height achieved was 93% of the anatomic root length of the tooth in the proximal segment and 96% of the anatomic root length of the tooth in the distal segment. There was significant, but low, negative correlation between presurgical cleft width and alveolar bone attachment of teeth adjacent to the grafted cleft site, after a mean radiographic follow-up of 3.1 years. Notching of the alveolar ridge in the region of the bone graft had a statistically significant low positive correlation with differing cleft widths.

This investigation was to determine the relationship between the success of secondary alveolar bone grafting and the position of the permanent cuspid relative to the cleft at the time of grafting. In this retrospective study utilizing periapical radiographs taken on cleft patients to evaluate bone grafting results, the subjects were patients treated at the Lancaster Cleft Palate Clinic, a private institution specializing in the care of cleft patients. Sixty-seven patients (20 BCLP; 47 UCLP) were selected for this study based on availability of quality radiographs and a minimum of 6-month post-surgical follow-up. All patients underwent alveolar bone grafting (mean age, 10 years 7 months). Presurgical radiographs were taken within 3 months of the operation. Post-surgical radiographs were taken to evaluate the outcome of grafting (mean follow-up, 2 years 10 months). Radiographs were traced and digitized on a total of 86 cleft sites. Presurgically, a ratio was used to determine the amount of cuspid crown emerged through the alveolus into the cleft site relative to the anatomic cuspid-crown length. Post-surgically, ratios of bone support for the teeth mesial and distal to the cleft were established by dividing the amount of root covered by bone by the anatomic root length. Ratios expressing the height of alveolar crest relative to the cementoenamel junction (CEJ) of adjacent teeth and amount of alveolar notching relative to the mesial tooth root length were also evaluated. Linear regressions of each of the five ratios of graft outcome on the cuspid-eruption ratio were done. No significant correlations could be found between final graft success and the amount of cuspid crown exposed in the cleft at the time of grafting. Cuspid position could not be shown to be a significant factor in determining graft success.

ABSTRACT Objectives: To describe qualitatively and quantitatively the directions and magnitudes of rotations of permanent maxillary central incisors and first molars in the mixed dentition in repaired complete unilateral cleft lip and palate (UCLP) and study their associations with absence of teeth in their vicinity. Materials and Methods: Dental casts and orthodontic records taken prior to orthodontic preparation for alveolar bone grafting of 74 children with repaired UCLP (53 male, 21 female; aged 8.9 ± 1.0 years) were studied. Directions and magnitudes of permanent maxillary central incisor and first molar rotations were recorded. Tooth absence was confirmed from longitudinal radiographic records. Incisor and molar rotations were analyzed in relation to the absence of teeth in their vicinity. Results: Distolabial rotation of the permanent maxillary central incisor was noted in 77.14% on the cleft side, while distopalatal rotation was noted in 82.19% on the noncleft side. Incisor rotation was greater when a permanent tooth was present distal to the cleft side central incisor, in the greater segment. The permanent maxillary first molar showed mesiopalatal rotation, which was greater on the cleft side and when there was absence of one or more teeth in the buccal segment. Conclusions: Presence and absence of teeth were associated with the severity of incisor and molar rotations in UCLP. Crowding of anterior teeth in the greater segment was associated with a greater magnitude of rotation of the cleft side permanent central incisor. Absence of one or more buccal segment teeth was associated with greater magnitude of rotation of the molar.

ABSTRACT Objectives: To measure the root lengths of maxillary central incisors (U1) and evaluate the relationship among U1 root length, tooth movement, and type of treatment appliance in patients with unilateral cleft lip and palate over a long-term follow-up period. Materials and Methods: Occlusal radiographs of 30 patients with unilateral cleft lip and palate, acquired less than 6 months before secondary alveolar bone grafting (SBG, T1) and after edgewise treatment (T2), were measured for U1 root length (R1 and R2, root lengths at T1 and T2, respectively). Frontal and lateral cephalometric radiographs acquired at eruption of U1 (T0), T1, and T2 were evaluated to determine the inclination and position of U1. Results: The average values of R1 and R2 on the cleft side were significantly lower than those on the noncleft side. Frontal cephalometric analysis revealed that the horizontal distance of the root apex from the median vertical line at T0 on the cleft side was significantly smaller than that on the noncleft side and was correlated with short U1 root length on the cleft side. On the other hand, R1 in patients treated with maxillary protraction appliances between T0 and T1 was significantly shorter than that in patients without maxillary protraction appliances. However, none of the changes in cephalometric measurements were correlated with root length. Conclusions: In patients with unilateral cleft lip and palate, the short root length of cleft-adjacent central incisors might be associated with the horizontal position of the root apex. In addition, orthodontic treatment with a maxillary protraction appliance before secondary alveolar bone grafting might be associated with short U1 root length.

Objective The purpose of this study was to evaluate if narrowing and approximation of the alveolar cleft through presurgical alveolar molding followed by gingivoperiosteoplasty (GPP) at the time of lip repair reduces the need for a bone-grafting procedure. Design This was a retrospective blind study of patients with unilateral or bilateral alveolar clefts who underwent presurgical infant alveolar molding and GPP by a single surgeon. Alveolar bone formation was assessed prior to the eruption of the maxillary lateral incisor or canine by clinical examination, panoramic and periapical radiographs, and/or a dental CT scan. The criterion for bone grafting was inadequate bone stock to permit the eruption and maintenance of the permanent dentition. Setting This study was performed at the Institute of Reconstructive Plastic Surgery by the members of the Cleft Palate Team. Patients All patients with unilateral (n = 16) or bilateral (n = 2) alveolar clefts who underwent presurgical infant alveolar molding and GPP by a single surgeon from 1985 to 1988 were studied. The control population consisted of all alveolar cleft patients (n = 14) who did not undergo alveolar modeling or GPP during the same time period. Interventions Presurgical alveolar modeling was performed with an intraoral acrylic molding plate. This plate was modified on a weekly basis to align the alveolar segments and close the alveolar gap. The surgical intervention consisted of a modified Millard GPP. Main outcome Measures The primary study outcome measure was the elimination of the need for a secondary bone graft in patients who underwent presurgical alveolar molding and GPP. Results Of the 20 sites in the 18 patients who underwent GPP, 12 sites did not require an alveolar bone graft. Of the 8 sites requiring a bone graft, 4 presented minimal bony defects. All 14 patients in the control group required bone grafts. Conclusions In this series of 20 alveolar cleft sites treated with presurgical orthopedics and GPP, 60% did not need a secondary alveolar bone graft in the mixed dentition.

Alveolar bone grafting plays a crucial role in cleft reconstruction. When neonatal presurgical orthodontia is successful in aligning the cleft segments, alveolar reconstruction can be initiated as a gingivoperiosteoplasty during primary cleft lip repair. In children with cleft palate, alveolar bone grafting is usually done after transverse maxillary expansion with a palatal expander. Exact timing of bone grafting is controversial; most centers initiate orthodontic evaluation/expansion between ages 7 and 8 years (beginning of mixed dentition) with an aim to bone graft before age 10 in order to allow osteogenic incorporation prior to eruption of the permanent canine teeth.

Background: Alveolar bone grafting is utilized to manage alveolar clefts in patients with cleft lip and palate. However, the timing of bone grafting is variable with conflicting evidence supporting the use of primary alveolar bone grafting (PABG) in clinical practice. Primary Aim: To provide a qualitative systematic review analysis of long-term outcomes after PABG. Materials and Methods: A qualitative systematic review was performed following the Cochrane Handbook and reported using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Summative findings were evaluated using Confidence in the Evidence from Reviews of Qualitative research to assess the quality of evidence supporting the findings. Results: After removing duplication, 2182 publications were identified, and 2131 were excluded after screening through titles and abstracts. Inclusion criteria for this study included patients who underwent PABG at 24 months of age or younger and a minimum of 5 year follow-up. Thirty-two publications met the inclusion criteria and were included for qualitative analysis. Primary outcome measures included cephalometric analysis, bone graft survival, occlusal analysis, hypomineralization, tooth eruption, radiograph analysis, and arch relationships. Four assessment themes were characterized from the systematic review: (1) bone graft survival, (2) craniofacial skeletal relationships, (3) occlusion and arch forms, and (4) recommendations for utilizing PABG in practice. Conclusion: The reported systematic review provides evidence that performing PABG leads to poor long-term outcomes related to bone graft survival and maxillary growth restriction despite some reported positive outcomes.
