“…The native atrophic alveolar ridge is often knife-edged, so bone grafting may be required. It has been reported that overcorrection is needed because of postoperative bone resorption [3][4][5] . Fracture and dislocation of bone fragments and wound dehiscence have been reported 3) .…”

The aim of this study was to evaluate a novel technique for inducing osteogenesis through original periosteal distraction in a canine mandible model. A periosteal distraction device was rigidly fixed to the mandible in three adult canines (i.e., six sides total). Two sides of 1 dog served as the control. In the experimental group, periosteal distraction was started 4 weeks after placement of the periosteal distraction device. The periosteum was distracted 0.5 mm per day until a height of 3 mm was reached. Distraction continued for 8 weeks. The animals were killed 14 weeks postoperatively. Radiographs were obtained after the devices were fitted and again after distracting the periosteum. Computed tomography (CT) was performed at weeks 1 and 8. Transverse images using OsiriX software were constructed based on the periosteal device to observe the amount of augmentation. Images over time were superimposed on the reference image using Photoshop software. It revealed the changes with time, which were measured. All 6 periosteal distraction devices remained rigidly fixed to the lateral surface of the mandibles. At completion of distraction, all operative sites had healed without evidence of infection or wound dehiscence. The amount of bone augmentation was calculated by comparing CT imagees. The experimental group showed increased width in the area of bone growth and in the bone itself on all six sides. Average increases were 0.7 mm in bone width and 3.31 mm in the area. Bone area and bone width were decreased slightly in the control group. There were significant differences between controls and the experimental group regarding bone width and bone area. We achieved bone augmentation using a custom-made periosteal distraction device. The amount of bone augmentation was calculated by comparing CT images.

“…Our osteotomy line was not at the Le Fort1 level, but was an alveolar osteotomy far below this level [11, 12]. This is less invasive and yet sufficient for performing simultaneous sinus lifting with an equal-volume mixture of particulate autogenous cancellous bone/ β -TCP and placing the distractor [12].…”

“…Alveolar distraction has recently gained acceptance as a predictable preimplant augmentation method for simultaneously regenerating bone and surrounding soft tissue [11, 12]. For an extremely atrophic posterior maxillary region, we have developed a modified technique that combines sinus lifting with simultaneous alveolar distraction, instead of the interpositional bone grafting of the Le Fort1 osteotomy [12].…”

We retrospectively reviewed a new preimplantation regenerative augmentation technique for a severely atrophic posterior maxilla using sinus lifting with simultaneous alveolar distraction, together with long-term oral rehabilitation with implants. We also analyzed the regenerated bone histomorphologically. This study included 25 maxillary sinus sites in 17 patients. The technique consisted of alveolar osteotomy combined with simultaneous sinus lifting. After sufficient sinus lifting, a track-type vertical alveolar distractor was placed. Following a latent period, patient self-distraction was started. After the required augmentation was achieved, the distractor was left in place to allow consolidation. The distractor was then removed, and osseointegrated implants (average of 3.2 implants per sinus site, 80 implants) were placed. Bone for histomorphometric analysis was sampled from six patients and compared with samples collected after sinus lifting alone as controls (n = 4). A sufficient alveolus was regenerated, and all patients achieved stable oral rehabilitation. The implant survival rate was 96.3% (77/80) after an average postloading followup of 47.5 months. Good bone regeneration was observed in a morphological study, with no significant difference in the rate of bone formation compared with control samples. This new regenerative technique could be a useful option for a severely atrophic maxilla requiring implant rehabilitation.

“…According to Ettl et al missing soft tissue extension may be more common with distraction of mandibular bone [46]. Kanno et al said if a vertical alveolar DO is planned within 6 months of surgery such as for tooth extraction or alveolar trauma there should be sufficient over correction to compensate for a bone relapse of upto50% [47]. As concluded by Predjik et al patients suffering from severe mandibular atrophy that were treated either with conventional augmentation techniques or VDO prove to be more susceptible to various complications wherein a majority of these complications occurred in the first year [48].…”

The purpose of this systematic review was to evaluate distraction osteogenesis for ridge augmentation in implant dentistry and also to present the associated advantages and limitations. A Medline and manual search was conducted to identify clinical studies concerning distraction osteogenesis in implant dentistry published between 1998 to 2012. 52 articles were assessed. The articles included evaluated the type of distractor used, augmentation achieved and the success and survival rate of implant placed in the augmented site. It was seen that when comparing methods of regeneration, a decreased treatment time is seen in cases of distraction osteogenesis. The reason for this lies in the fact that within 12 weeks the distraction segments are formed and there is a increase noted in the height of the alveolar bone, from 5 to 15 mm as well as an implant survival rate of 95.7%. It can be concluded that distraction osteogenesis is a relatively simple, effective and reliable technique for alveolar ridge reconstruction in contemporary implant dentistry. It can be considered versatile owing to its simplicity, possibility of avoiding bone grafts, infections and blood transfusions. The fact that graft and membrane exposure or inadequate tissue coverage do not pose complications, makes this an effective method of bone augmentation in implantology.
