AbstractAlveolar Bone Grafting is a clinical procedure which is performed to maintain the integrity of the alveolar arch in cleft patients. This clinical procedure helps in facilitating eruption of canine and lateral incisors. This chapter discusses the normal anatomy of alveolus, significance of cleft alveolus, surgical steps to ensure separation of a well-defined oral and nasal layer, donor sites for bone grafting, harvesting techniques and final closure of the alveolar cleft. In addition, this chapter further highlights the recent developments in the field of bone regeneration.

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.

Objective This investigation was conducted to determine the agreement between three-dimensional (3-D) calculations from CAT scans and two-dimensional (2-D) calculations from standard dental radiographs in evaluating bone support for cleft-adjacent teeth after primary bone grafting. Design This retrospective study utilized CAT scans and dental radiographs taken of the alveolar cleft in patients an average of 11 years after primary bone grafting. Setting The subjects were patients treated by the Cleft Palate Team at Children's Memorial Hospital and Loyola University Medical Center, Chicago, Illinois. Patients Fourteen UCLP patients (9 males, 5 females) agreed to participate In this study by undergoing CAT scan assessment of their alveolar cleft sites. They also had to have periapical or occlusal radiographs of the grafted cleft site taken within 6 months of the CAT scan. Interventions All patients underwent primary lip repair, placement of a passive palatal plate, primary alveolar bone grafting (mean age 6.4 months), and palatoplasty before 1 year of age. Major tooth movement through final orthodontics was completed by the time of the radiographic assessment. Main Outcome Measures CAT scan sections were reformatted and reconstructed to three-dimensionally calculate the percentage of root covered by bone support for the 15 teeth adjacent to the grafted cleft sites. Dental radiographs of the same teeth were also traced and digitized. Percentages of root supported by bone were also established using the dental radiographs by dividing the amount of root covered by bone, by the anatomic root length. Results A paired, two-sample t test revealed no significant differences between the two methods of assessment, while linear regression showed a statistically significant correlation between the CAT scan assessment and the percentages found on the radiographs. Conclusions Routine dental radiographs were able to estimate the total 3-D bone support for the roots of cleft adjacent teeth as determined by CAT scan to a statistically significant degree when groups where compared. The clinical significance for evaluation of individual cases was less impressive with a wide range of variability and a level of agreement that required acceptance of differences up to 25%.

Secondary Alveolar Bone Grafting

Several authors have proposed classifications to analyze the quality over time of secondary alveolar bone grafting. However, little discussion has been held to quantitatively measure the secondary bone grafting for correction of nasal deformity associated to cleft palate and lip. Twenty patients with unilateral alveolar cleft, who underwent secondary alveolar bone grafting, were studied with 3D computer tomography. The height between the inferior portion of the pyriform aperture and the incisal border of the unaffected side (height A) and the affected side (height B) was measured using a software Mirror. A percentage was then obtained dividing the height B by the height A and classified into grades I, II, and III if the value was greater than 67%, between 34% and 66%, or less than 33%. Age, time of followup, initial operation, and age of canine eruption were also recorded. All patients presented appropriate occlusion and function. Mean time of followup was 7 years, and mean initial age for operation was 10 years old. 16 patients were rated as grade I and 4 patients as grade II. No cases had grade III. We present a new grading system that can be used to assess the success of secondary bone grafting in patients who underwent alveolar cleft repair.

Objective To demonstrate the feasibility of rapid maxillary expansion (RME) after alveolar bone grafting (ABG) in complete unilateral cleft lip, alveolus and palate (UCLP) without damage to the grafted area. Setting Hospital for Rehabilitation of Craniofacial Anomalies (HRAC), University of São Paulo, Department of Orthodontics. Patient A case report of a 10-year-old boy with a complete UCLP who was treated with RME after secondary ABG procedure. RME was performed 1.3 years after the bone grafting with rhBMP-2 in collagen membrane. Result Postexpansion cone-beam computed tomography (CBCT) axial and coronal sections demonstrated the opening of the midpalatal suture in the premaxilla without damages to the alveolar bone grafting region. Postretention CBCT images showed bone formation at the split midsuture of the premaxilla. Conclusion Rapid maxillary expansion performed after ABG with rH-BMP2 led to complete opening of the premaxillary midline suture without compromising the integrity of the grafted alveolar cleft.
