ABSTRACTIn patients with cleft lip and palate, bone grafting in the mixed dentition in the residual alveolar cleft has become a well-established procedure. The main advantages can be summarised as follows: stabilisation of the maxillary arch; facilitation of eruption of the canine and sometimes facilitation of the lateral incisor eruption; providing bony support to the teeth adjacent to the cleft; raising the alar base of the nose; facilitation of closure of an oro-nasal fistula; making it possible to insert a titanium fixture in the grafted site and to obtain favourable periodontal conditions of the teeth within and adjacent to the cleft. The timing of the ABG surgery take into consideration not only eruption of the canine but also that of the lateral incisor, if present. The best time for bone grafting surgery is when a thin shell of bone still covers the soon erupting lateral incisor or canine tooth close to the cleft.

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.

Objective To determine if secondary alveolar bone grafting (SABG) timing in patients with cleft lip and palate (CLP) influences the future need for additional maxillary advancement procedures, particularly Le Fort I osteotomy with rigid external distraction (RED). Design Retrospective cohort study. Groups were separated by SABG timing: early mixed dentition (ages 68 years) or late mixed dentition (ages 9-11 years). The criterion for RED was negative overjet ≥8 mm, and sufficient dental development for RED. Setting Single tertiary care institution. Patients Patients with CLP that underwent SABG from 2010 to 2015. Exclusion criteria included syndromic conditions, SABG surgery at age >12 years, current age <12 years, and <2 years follow-up. 104 patients were included. Main outcome measures The number of RED candidates and treated patients. Results There was no statistical difference in the number of RED candidates ( P  =  .0718) nor treated patients ( P  =  .2716) based on SABG timing; stratification by laterality was also insignificant. Early SABG is associated with higher odds of being a RED candidate (pooled, unilateral, bilateral) and treated patient (pooled and unilateral); however, there were no statistically significant associations between SABG timing and the number of RED candidates and treated patients as determined by logistic regression models. Conclusion There is no statistically significant association between SABG timing and the odds of being a RED candidate or treated patient. Future prospective studies are recommended to assess the relationship between SABG timing and maxillary growth in patients with CLP.

Secondary Alveolar Bone Grafting

Secondary alveolar bone grafting (SABG) is associated with donor site morbidities. We aimed to compare the outcomes of SABG and extensive gingivoperiosteoplasty (EGPP) at the mixed dentition stage. This single-blinded, randomized, prospective trial enrolled 50 consecutive patients with unilateral complete cleft lip and palate who had residual alveolar bone cleft, of which 44 (19 SABG, 25 EGPP) completed the study. Bone volumes before surgery, 6 months postoperatively, and 1-year postoperatively were compared using computed tomography. The Bergland scale score was recorded at 6 months postoperatively. Both groups had the same preoperative alveolar cleft volume. On the Bergland scale, 21, 3, and 1 patient in the EGPP group and 16, 2, and 1 patient in the SABG group were classified as types I, II, and IV, respectively, which did not show significant difference. With perioperative orthodontic treatment, the 1-year residual bone defect volume in both groups did not show significant difference (SABG 0.12 cm3 vs. EGPP at 0.14 cm3, p > 0.05). The study was not able to reveal much difference between SABG and EGPP combined with perioperative orthodontic treatment.

Alveolar Bone Grafting

Objective: To examine the effect of migration of the germ of the lateral incisor into the bone for eruption factors on bone bridge resorption. Methods: Twenty-five subjects who underwent secondary alveolar bone graft were enrolled. The volume of the alveolar bone grafts immediately after the operation (V1), bone bridge formation 6 months postoperatively (V2), and tooth (teeth) migration into the bone bridge (Vt) were measured using a computed tomography (CT) image analyzer. Based upon these measurements, the following points were examined: (1) the correlation between the tooth-occupied ratio (Rt = Vt/V2 × 100) and the ratio of bone bridge resorption (Rv = (V1 − V2)/ V1 × 100); and (2) comparison of the tooth-occupied ratio (Rt) and the ratio of bone bridge resorption (Rv) between the groups with and without the germ of the lateral incisor. Results: A significant negative correlation was found between Rv and Rt (p < .001). Comparison of Rv and Rt between the groups with and without a germ of the lateral incisor revealed that both indices were significantly higher in the former group than the latter one (p < .05). Conclusion: In cleft lip and palate patients with a germ of the lateral incisor, it is beneficial to carry out secondary bone grafting to the alveolar cleft at the age of 5 to 7 years, preceding eruption of the canine, in order to form a good bone bridge that will facilitate eruption of the lateral incisor and subsequent normal dentition and occlusion.

Objective: This study was conducted to evaluate the effects on facial growth of alveolar bone grafting in the mixed dentition for patients with UCLP. Design: Retrospective cephalometric study. Setting: Craniofacial Treatment and Research Centre, The Hospital for Sick Children, Toronto, Ontario, Canada. Patients: The 58 patients participating in the study had a history of complete unilateral cleft lip and palate, all of which were repaired by the same plastic surgeon. Interventions: Twenty-one patients received an iliac-crest alveolar bone graft at a mean age of 10.3 years, while 37 did not receive an alveolar bone graft. Lateral cephalometric radiographs were obtained on all patients at two different times: at a mean age of 9.4 years (prior to bone grafting in the grafted group) and at a mean age of 15.2 years. Main Outcome Measures: All radiographs were traced and digitized by the same person, using cephalometric computer software. Superimposition and cephalometric analysis was undertaken to investigate the differences between the two groups in the 5.6-year experimental period. A two-way analysis of covariance was used for evaluation of the statistical significance of the results. Results: No statistically significant differences were found in 14 of the 15 cephalometric measurements performed. Harvold's maxillary unit length was statistically significantly shorter in the grafted group, although a lack of correlation with angular measurements and inherent problems with this specific measurement raise doubts in this finding. Conclusion: Mixed dentition bone grafting does not affect subsequent vertical and A-P development of the maxilla in complete unilateral cleft lip and palate patients during the first several postoperative years.

Objective: To quantify dental anomalies in permanent dentition associated with complete unilateral cleft lip and palate and to survey treatment modalities used to address these problems. Method: Retrospective study of 116 children with complete unilateral cleft lip and palate treated at SickKids since birth. Presence and morphology of lateral incisors and second premolars were determined. Orthodontic, surgical, and/or prosthetic procedures were analyzed. Results: The cleft-side lateral incisor was absent in 93.1% of finished cases. The lateral incisor mesial to the cleft was present in 4.3%, absent due to agenesis in 75.9%, and extracted in 19.8% of cases. The lateral distal to the cleft was present in 2.6%, absent due to agenesis in 33.6%, and extracted in 63.8% of cases. Of 105 lateral incisors, only one had normal morphology. Noncleft-side lateral incisors were absent in 16% of finished cases. Absence was due to agenesis in 12.1% of cases and extraction in 4.3%. When the lateral incisor was missing, closure of the dental space occurred by orthodontic tooth movement after alveolar bone grafting (45%); surgical closure with simultaneous alveolar bone grafting (35%); prosthetic closure (17%); and 3% were failures. Agenesis of premolars occurred in 12.1% of cleft-side and 10.3% of noncleft-side maxillary second premolars. Conclusions: The cleft-side lateral incisor is rarely present at the conclusion of orthodontic and surgical treatment of complete unilateral cleft lip and palate. Often absent due to agenesis, when present it is typically abnormal in size and bone support and is commonly extracted in favor of canine substitution.

Secondary Alveolar Bone Grafting

Objective: To introduce a surgical technique for secondary alveolar bone grafting performed in conjunction with premaxillary osteotomy and guided tissue regeneration in children with bilateral clefts. This paper also looks at the outcomes of this surgery in a series of 15 consecutive patients. Methods: Secondary alveolar bone grafting (with a premaxillary osteotomy and guided tissue regeneration with a collagen membrane) is usually carried out in the mixed dentition stage. This retrospective study used patients’ medical records, radiographs, and clinical examination to assess the outcome of the surgery. Patients were followed up for an average of 3 years. Results: Bone grafting was successful in all cases. No premaxillae were lost and there was no long-term morbidity of the donor site. Radiographic assessment of the bone heights showed an average of 94% retention, 3 months postoperatively. Preliminary assessment of maxillary canine eruption is encouraging, with 79% being fully erupted in those patients who are at least 3 years post–bone grafting. Conclusion: Premaxillary osteotomy allows repositioning of the premaxilla to its optimal preplanned position and successful closure of all fistulae. We have found that use of a collagen membrane is a useful adjunct.

Objective: To determine whether there is any correlation between initial maxillary arch dysmorphology patterns in complete bilateral cleft lip/palate (BCLP) and the subsequent occlusal relationship in early mixed dentition. Design: This retrospective study evaluated 41 consecutive patients with complete BCLP who were managed by a single tertiary cleft team between 1983 and 1992. All patients had bilateral synchronous lip adhesions with placement of a passive alveolar molding appliance at 4 to 8 weeks of age; definitive modified Manchester lip repair at 6 to 8 months of age; and a one-stage “two-flap” palatoplasty at 14 months of age. Neither gingivoperiosteoplasty nor early alveolar bone grafting was performed. Four patients required early surgical premaxillary setback because of adverse social reactions to a very protrusive premaxilla. All patients (7 to 9 years) were assessed prior to initiation of first-phase orthodontics (maxillary expansion) in anticipation of alveolar bone grafting. Cleft team records were reviewed to determine initial maxillary arch dysmorphology, treatment, and occlusal relationships in early mixed dentition stage. The initial maxillary dysmorphology was classified using a new grouping based on orientation of the vomer, the intercanine distance, and its symmetry. Patterns of mixed dentition occlusion were then compared with group type, and predication tables were generated. Because midface retrusion is the major dentoskeletal morbidity in cleft patients, angle Class I and II occlusions were designated as “favorable” and Class III as “unfavorable.” Results: In early mixed dentition, approximately three-fourths of patients with complete BCLP had favorable occlusion and one-fourth unfavorable occlusion. The occlusal status seemed unrelated to the initial maxillary arch dysmorphology, the use of early passive alveolar molding appliance, or surgical premaxillary setback. Conclusion: Patterns of variation within the initial dysmorphology of the maxillary arch in infants with complete BCLP cannot be used to predetermine subsequent molar occlusal relationships in the mixed dentition.

Significant Difference

To three-dimensionally assess and visualize the eruption path and development of the maxillary canine following alveolar bone grafting in patients born with cleft lip and palate. A further objective of this analysis was to assess how the presence of the lateral incisor impacts the eruption path of the canine. Observational follow-up study. Stockholm Craniofacial Team, Karolinska University Hospital, Sweden. Thirty children born with non-syndromic unilateral cleft lip with or without palate were consecutively included. CBCT scans of the maxilla were taken six months before and six months after the alveolar bone-grafting surgery for each patient. Canine eruption (angulation and vertical movement) and canine development (length and volume). There was a significant difference pre- and post-operatively of the canine angulation between the cleft and non-cleft sides. The mean angulation on the cleft side was 14.7° (SD  =  11.1°) while on the non-cleft side, it was 4.9° (SD  =  9.2°). No significant differences were noted between cleft-side and non-cleft side canines in terms of amount of vertical eruption and volumetric development. Absence of the lateral incisor did not significantly contribute to either canine angulation or its vertical eruption on the cleft-side. Higher angulation of the canine on the cleft side indicates a higher risk of future canine impaction. Presence or absence of the lateral incisor did not significantly affect canine angulation or its vertical eruption. Increased age and children born with total cleft lip and palate imply a higher risk of angulated canines on the cleft side.
