The aim is to describe bilateral vertical ridge augmentation with intraoral block grafts and guided bone regeneration in the posterior mandible in preparation for implant placement. A 61-year-old woman, edentulous in the posterior mandible, presented for implant rehabilitation. The radiographic study showed 3 to 6 mm of bone height from the ridge to the mandibular canal. Autogenous bone block grafts from the chin and the mandibular ramus, harvested with ultrasonics, were used to augment the alveolar ridge. To reduce resorption, the grafts were covered with particulate alloplastic material and a collagen membrane. Delayed implants were placed 6 months after vertical augmentation, and 3 months later implants were loaded with a fixed prosthesis. A temporary sensory complication occurred, but 12 months after implant loading, there were no failures. In this case report block bone grafting was a feasible option to vertically augment the alveolar ridge in the posterior mandible.

Because a concept of an osteointegrated dental implant system was established, prognosis of a dental implant at treatment improved and the treatment of restoration for missing teeth was changed. However, a dental implant treatment into atrophic jaw bone requires bone augmentation, obviously. At this time, we studied for the purpose of establishing the evidence of each method for clinical application of these bone augmentation method, such as guided bone regeneration (GBR), and autogenous bone block graft (BBG). In addition, we pursued the basic study of the evidence about the bone formation with platelet rich plasma (PRP) which recognized the availability in clinic. Furthermore, we present the results of basic studies which we tested for the purpose of applying a low-intensity pulse ultrasound (LIPU) irradiation applied to a fracture treatment in orthopedics area to intra-oral area, specially the condition after implant placement. In the results of comparison with GBR site and BBG, the differences of labeling bands were observed with a fluorescence microscopy. There was much labeling bands on GBR sections in comparison with BBG. This meaning that the bone remodeling around implants at GBR site was more active than BBG site. And the new bone formation by PRP was identified on soft X-ray graphically at first week after PRP applied mandible bone defect (experimental side). At same region of first week specimen, we confirmed positive reactions of platelet derived growth factor

Purpose – The purpose of this paper is to describe two different approaches for manufacturing pre-formed titanium meshes to assist prosthetically guided bone regeneration of atrophic maxillary arches. Both methods are based on the use of additive manufacturing (AM) technologies and aim to limit at the minimal intervention the bone reconstructive surgery by virtual planning the surgical intervention for dental implants placement. Design/methodology/approach – Two patients with atrophic maxillary arches were scheduled for bone augmentation using pre-formed titanium mesh with particulate autogenous bone graft and alloplastic material. The complete workflow consists of four steps: three-dimensional (3D) acquisition of medical images and virtual planning, 3D modelling and design of the bone augmentation volume, manufacturing of biomodels and pre-formed meshes, clinical procedure and follow up. For what concerns the AM, fused deposition modelling (FDM) and direct metal laser sintering (DMLS) were used. Findings – For both patients, a post-operative control CT examination was scheduled to evaluate the progression of the regenerative process and verify the availability of an adequate amount of bone before the surgical intervention for dental implants placement. In both cases, the regenerated bone was sufficient to fix the implants in the planned position, improving the intervention quality and reducing the intervention time during surgery. Originality/value – A comparison between two novel methods, involving AM technologies are presented as viable and reproducible methods to assist the correct bone augmentation of atrophic patients, prior to implant placement for the final implant supported prosthetic rehabilitation.
