Wedge Technique

Autogenous bone is still considered the gold standard in bone augmentation for implant insertion in atrophic ridges. However, augmentation of multiple edentulous atrophic segments usually necessitates the use of extraoral donor sites. This chapter introduces the Wedge Technique, as a new bone augmentation method that can augment multiple edentulous ridges with intraoral cortical bone grafts. Patients with moderate to severe ridge atrophy in different regions of the jaws were treated with the wedge technique (WT). Patients received a panoramic radiograph immediately after the surgery, and they were examined clinically and radiographically (periapical radiograph) every 2 weeks. At four months, CBCT was performed to evaluate the bone gain. Reentry was performed after 4 to 5 months to evaluate the new bone volume and quality and to insert implants. The follow-up period ranged from 30 to 120 months. The healing process was uneventful, with minimal morbidity. The success rate was 95%, the bone gain average was 3–6 mm vertically and 3–9 mm horizontally. The wedge technique can augment multiple segments of atrophic ridges with a small amount of autogenous graft. The achieved bone volume was satisfying, especially that the majority of the augmented areas were at posterior mandibular defects.

Background. Bone augmentation ensures a favorable 3-dimensional position of implants. Onlay grafting is one of the techniques in ridge augmentation, which can be performed with the use of xenogenous blocks. Methods. Three cases of the vertical and horizontal ridge are discussed, which were augmented using xenogenous blocks. The blocks were shaped in a favorable size and puzzled along the grafting area. All the gaps were filled with granular xenografts. The flaps were coronally advanced to obtain primary closure. Results. An average of 4.2-mm gain in width and 4.2-mm gain in height of the ridge was observed at the implantation stage. Conclusion. The outcomes of these cases could pave the way for suggesting xenograft blocks for augmenting wide areas of the alveolar ridge on average of 4 mm in width and height in selected cases as an alternative to standard autogenous blocks. Long-lasting xenograft ensures implant and lip support in the esthetic zone.

AbstractInformation regarding profilometric changes at a soft tissue level following implant placement with different protocols is insufficient. Therefore, this study aimed to comparatively investigate the profilometric tissue changes with respect to late implant placement following alveolar ridge preservation (LP/ARP) and early implantation (EP) in periodontally compromised non-molar extraction sites. Sixteen patients were randomly assigned to the following groups: implant placement 4 months post-ARP (group LP/ARP) and tooth extraction and implant placement 4–8 weeks post-extraction (group EP). Dental impressions were obtained immediately after final prosthesis insertion and at 3, 6, and 12 months. At the time of implant placement, bone augmentation was performed in the majority of the patients. Profilometric changes of the tissue contour were minimal between the final prosthesis insertion and 12 months in the mid-facial area (0.04–0.35 mm in group LP/ARP, 0.04–0.19 mm in group EP). The overall tissue volume increased in both groups (1.70 mm3 in group LP/ARP, 0.96 mm3 in group EP). In conclusion, LP/ARP and EP led to similar stability of the peri-implant tissue contour between the final prosthesis insertion and at 12 months. Moreover, the change of peri-implant tissue on the soft tissue level was minimal in both modalities.

Objective: We combined heads-up 3-dimensional (3D) 27-gauge microincision vitrectomy surgery (27GMIVS) with a very low-intensity illumination system. Methods: This study was based on a retrospective, interventional case series of 6 eyes of 6 patients with macular disease. All patients underwent heads-up 3D 27GMIVS and the power of the intraocular illuminator was set to its minimum level, 1% (approximately 0.1 lm), throughout the surgery. Results: We found that the procedure was easy when the heads-up 3D system was used, but not through the eyepiece of a microscope. All surgeries were successfully finished without any complications. Postoperative visual acuity was restored or maintained in all eyes during the follow-up period. Conclusion: Heads-up, 3D system-assisted 27GMIVS with minimal illumination enabled excellent intraoperative visualization of retinal tissues, caused minimal phototoxicity to the macular retinal cells, and might therefore represent the next step in the development of an ideal, minimally invasive method of treating macular disease.

Abstract Background: Bone grafting is commonly used for reconstructing skeletal defects in the craniofacial region. Several bone augmentation models were developed to optimize bone regeneration in both vertical and horizontal dimesions. Aim: The aim of this study was to develop a surgical animal model for establishing a three-dimensional (3D) grafting environment in the animal's mandibular ramus for horizontal and vertical bone regeneration using osseous shell technique, as in human patients. Materials and methods: Initial osteological and imaging survey were performed on a postmortem skull of a New Zealand White (NZW) rabbit skull, Oryctolagus cuniculus, for feasibility assessment for performing the surgical procedure. 3D osseus defect was created in the mandibular ramus through a submandibular incision and the osseous shell plates were stabilized with osteosynthesis fixation screws and defect filled with particular bone grafting material. The in-vivo surgical procedures were conducted in four 8-week-old NZW rabbits utilising two osseous shell materials: xenogenic human cortical plates, and autogenous rabbit cortical plates, and the created 3D defects were filled using xenograft and allograft bone grafting materials. The healed defects were evaluated for bone regeneration after 12 weeks using histological and Cone Beam Computed Tomography (CBCT) imaging analysis. Results: Clinical analysis at 12 weeks after surgery revealed the stability of the 3D grafted bone augmentation defects using the osseous shell technique. Imaging and histological analyses confirmed the effectiveness of this model in assessing bone regeneration. Conclusion: The rabbit model is an efficient and reliable biological method for creating a seizable three-dimensional horizontal and vertical bone regeneration model in the mandibular ramus using osseous shell technique for testing various bone-substitute materials testing without compromising the health of the animal. The filled defects could be analyzed for osteogenesis, quantification of bone formation, and healing potential, using histomorphometric analysis, in addition to 3D morphologic evaluation using radiation imaging.
