Ridge Split

Horizontal ridge deficiency, particularly in the mandibular arch, poses a challenge for implant supported rehabilitation. Ridge split, along with expansion, allows simultaneous implant placements in such defects, and avoids the delay which usually follows hard tissue augmentation procedures. A 53 year old female with missing mandibular anterior teeth and a bucco-lingual ridge deficiency was treated using the ridge split technique and simultaneous implant placement. Demineralized freeze dried bone allograft (DFDBA) along with anorganic bovine bone (ABB) was packed in the expanded crypt and covered by a collagen membrane. Following successful implant osseointegration, soft tissue augmentation by a vestibular deepening procedure with a strip of autogenous free gingival graft was performed. Prosthetic rehabilitation was done using a cement retained prosthesis after the healing phase. The case was then followed up for 3 years where stable results were noted. Condensed treatment time and a predictable outcome was achieved by using this technique.

Abstract Background The purpose of this study was to evaluate the volumetric changes in partially edentulous alveolar ridges augmented with customized titanium ridge augmentation matrices (CTRAM), freeze-dried bone allograft, and a resorbable collagen membrane. Methods A pre-surgical cone beam computed tomography (CBCT) scan was obtained for CTRAM design/fabrication and to evaluate pre-surgical ridge dimensions. Ridge augmentation surgery using CTRAM, freeze-dried bone allograft, and a resorbable collagen membrane was performed at each deficient site. Clinical measurements of the area of augmentation were made at the time of CTRAM placement and re-entry, and a 2nd CBCT scan 7 months after graft placement was used for volumetric analysis. Locations of each CTRAM in situ were also compared to their planned positions. Re-entry surgery and implant placement was performed 8 months after CTRAM placement. Results Nine subjects were treated with CTRAM and freeze-dried bone allograft. Four out of the nine patients enrolled (44.4%) experienced premature CTRAM exposure during healing, and in two of these cases, CTRAM were removed early. Early exposure did not result in total graft failure in any case. Mean volumetric bone gain was 85.5 ± 30.9% of planned augmentation volume (61.3 ± 33.6% in subjects with premature CTRAM exposure vs. 104.9% for subjects without premature exposure, p = 0.03). Mean horizontal augmentation (measured clinically) was 3.02 mm, and vertical augmentation 2.86 mm. Mean surgical positional deviation of CTRAM from the planned location was 1.09 mm. Conclusion The use of CTRAM in conjunction with bone graft and a collagen membrane resulted in vertical and horizontal bone gain suitable for implant placement.

ABSTRACT Periodontal accelerated osteogenic orthodontics (PAOO) is a procedure applying the clinical science of alveolar corticotomy, particulate bone grafting, and the application of orthodontic forces, for accentuated tooth movement. This is theoretically based on the bone healing pattern known as the regional acceleratory phenomenon (RAP). A series of 12 cases, including 8 females and 4 males, were included in the study. The cases were referred from the Department of Orthodontia to the Department of Periodontology, ADC (R&R), having bimaxillary protrusion with an increased overjet. After initial orthodontic alignment, buccal corticotomy procedure was planned. A full-thickness mucoperiosteal flap was reflected from maxillary canine to canine beyond the root apices. Vertical corticotomy cuts were given in the alveolar bone with piezo blades 2 mm apical to the crestal bone in the inter-radicular space midway between the root prominences and were joined by the horizontal cuts apically. Demineralized freeze-dried bone allograft (DFDBA) was placed in the surgical area. The flaps were sutured and pack was placed. Orthodontic retraction was started 2 weeks after the corticotomy procedure. Using this procedure, the treatment objectives were met in just half to one-third of the reported conventional treatment time and the large overjet was reduced to normal. Pre- and posttreatment clinical parameters were recorded, statistically analyzed, and corroborated with similar orthodontic treatment procedures without the use of the corticotomy technique. The present periodontal (PDL) intervention results in quick and stable results for the correction of bimaxillary protrusion cases. It enhances the esthetics and posttreatment orthodontic stability.
