“…The authors suggested that it was caused by radicular surface exposure, resulting from inter-dental osteotomies in narrow inter-dental spaces (Bell et al, , 1999. When a true latency period of 5e7 days was respected, crestal bone loss was not observed and the attached gingiva maintained its preoperative level (Guerrero et al, 1997;Kewitt and Van Sickels, 1999;Niederhagen et al, 1999;Mommaerts et al, 2005). These findings, and the ones from the present experiment, suggest that keeping the junctional epithelium attached, or allowing its reattachment, may be more important than keeping bone on the roots.…”

“…These findings, and the ones from the present experiment, suggest that keeping the junctional epithelium attached, or allowing its reattachment, may be more important than keeping bone on the roots. The periodontal response can though be greatly influenced by the preoperative periodontal status and maintenance of good oral hygiene habits in the postoperative period (Kewitt and Van Sickels, 1999;Mommaerts et al, 2005). Andreasen et al (1990) defined periodontal healing by ''a newly formed PDL space surrounding the entire root periphery.''…”

“…In animal experiments (Bell et al, , 1999Del Santo et al, 2000) and clinical investigations (Guerrero et al, 1997;Weil et al, 1997;Kewitt and Van Sickels, 1999;Cope et al, 2002) inter-dental callus formation and tooth movements were studied, and occasionally accidental damage to teeth and periodontal structures was reported. Mommaerts et al (2005) described the periodontal status and tooth vitality changes during the distraction and consolidation phase more in depth in a clinical study. Also in this study, however, the surgeon tried to avoid damage to the dental structures.…”

SUMMARY. Aim: The objective of the study was to evaluate the impact of dental lesions on the periodontium, in a canine model of mandibular osteodistraction. Material and methods: In six adult male Beagle dogs, an osteotomy was made between the right second lateral incisor and canine, and a distraction device placed. The roots adjacent to the osteotomy were deliberately damaged by the reciprocating saw and chisel, with preservation of the attached gingiva. The osteodistraction protocol used was: latency of 7 days, rate of distraction 1 mm per day, and rhythm once a day for 5 days. Vital staining was carried out with tetracycline, Xylenol Orange and Calcein Green. The dogs were sacrificed after 12 weeks of consolidation and the specimens were evaluated with light microscopy (native, polarized light, fluorescence, and after toluidin blue staining). Results: The periodontal ligament (PDL) regeneration was observed in the 2500 slices examined. Cementum and dentine lesions were repaired by cellular cementum. Loose dentine and cementumedentine fragments were embedded in regenerated PDL and their surface repaired by cementum. By means of light microscopic examination and within the limited observation time, no degenerative pulpal changes were found, when the pulp canal was not entered. Extensive pulp exposure and destruction resulted in ingrowth of the PDL and bone-like tissue. In that case, cellular cementum also lined the dentine surface of the pulp canal. Conclusion: Although there was an extensive reparative response to the para-pulpal lesions, none of the changes observed showed evidence of a loss of functional integrity of the periodontium at the distraction site. The fate of the tooth with exposed pulp canal remains uncertain. Ó 2008 European Association for Cranio-Maxillofacial Surgery

“…Thus, orthodontic tooth movement increased bone volume at the distraction site. Mommaerts et al 16 suggested that as long as the tooth apices are not damaged during osteotomy, periodontal and dental morbidity is transient and limited to the distraction and consolidation period. In the present case, tooth movement into the distraction region was initiated after the consolidation period.…”

Treatment of unilateral buccal crossbite with mandibular symphyseal distraction osteogenesis

The aim of this report is to present the treatment of a 14-year-old boy with scissors-bite. Mandibular symphyseal distraction osteogenesis (MSDO) with tooth-supported distractor was performed to expand the mandible, and intermaxillary cross elastics were used. The mandible was expanded approximately 9 mm. Asymmetric widening was done by using cross elastics and MSDO simultaneously. The buccal crossbite was corrected successfully. After a 2-year observation period, widening of the mandible using this procedure was judged to be stable. (Korean J Orthod 2011;41(1):59-69)

“…If significant dental crowding is also present, cone-beam is an invaluable tool for optimal visualization. Some authors have suggested that orthodontic treatment during the preoperative period needs to be started in order to create a divergence of the roots and/or a sufficient space near the osteotomy tract planned by the surgeon 10,21,26 . These precautions make it possible to avoid injuries to the dental roots and the periodontal ligament, particularly if the available space is insufficient.…”
