Aim: Today, dental implant applications have become the most preferred option in the treatment of tooth deficiencies. Long-term successful results in dental implant applications depend largely on the volume and quality of the hard and soft tissues in the relevant region. Insufficient soft tissues and alveolar crest resorption complicate implant applications. Grafts and additional surgical procedures are required to compensate for resorption and to provide bone augmentation. Shell technique, one of the augmentation methods used in the treatment of alveolar bone defects, is an important procedure for guided bone regeneration. The purpose of this case report is to describe the treatment of vertical and horizontal bone loss with the Shell technique using allogeneic cortical grafts. Methodology: A 58-year-old female patient without any systemic disease was admitted to our clinic with the complaint of tooth loss in the right posterior mandibular region. In the intraoral and radiological examinations, it was determined that the bone volume in the relevant region was not sufficient for dental implant. Two-stage surgical treatment was planned for the patient. First, vertical and horizontal bone defects were augmented with allogeneic cortical graft application under local anesthesia. After the healing process, dental implants were placed in the sufficient volume of the alveolar bone and the patient's treatment was completed. Conclusion: Allogeneic grafts in the treatment of alveolar crest defects; it is a good alternative to autogenous bone grafts,there is no need for a second surgical field and the resulting reduction in morbidity.   How to cite this article: Eriş Derkuş F, Yılmaz UN.

Abstract Background Autogenous bone augmentation is the gold standard for the treatment of extended bone defects prior to implantation. Bone augmentation from the zygomatic crest is a valuable option with several advantages, but the current literature for this treatment is scant. The aim of this study was to evaluate the increase in bone volume after locoregional bone augmentation using autogenous bone from the zygomatic alveolar crest as well as the complications and success rate. Results Analysis of the augmented bone volume in seven patients showed a maximum volume gain of 0.97 cm3. An average of 0.54 cm3 of autogenous bone (SD 0.24 cm3; median: 0.54 cm3) was augmented. Implantation following bone augmentation was possible in all cases. Complications occurred in three patients. Conclusion The zygomatic alveolar crest is a valuable donor site for autogenous alveolar onlay grafting in a locoregional area such as the maxillary front. Low donor site morbidity, good access, and its suitable convexity make it a beneficial choice for autogenous bone augmentation.

Maxillary Region

Periodontal defects and trauma at the anterior maxillary region can cause a severe alveolar ridge deficiency resulting in an unesthetic view. Ideal implant positioning can be compromised by inadequate alveolar bone in terms of height and width. Reconstruction of osseous defects with autogenous bone allows ideal implant positioning and creates a more natural soft and hard tissue profile, which influences esthetic crown anatomy at the anterior maxillary region. In this case report, an alveolar ridge defect due to periodontally compromised tooth extraction was filled with autogenous bone cylinder and dental implant at one-stage surgery. In the presented case, a new technique was described which included bone reconstruction of the defects at the anterior maxillary region and simultaneous placement of the dental implant.

Histologic Evaluation

Background: Augmentation of vertical bone defects remains the corner stone in periodontal tissue engineering. The amount and quality of alveolar bone available in all dimensions affects the success of dental implants for restoration of edentulous areas. Adequate and healthy bone supports the degree of osseointegration which in turn affects the long-term success of oral implants. The primary aim of the study was to histologically evaluate autogenous block grafts versus synthetic block grafts for the treatment of atrophic vertical and horizontal bony defects (Siebert Class III) in the anterior esthetic zone of the mouth. The secondary aim was to clinically and radiographically evaluate the outcomes of the procedure. Methods: This was a randomized controlled clinical study with a statistically determined sample size of 10 patients per group and a total of 20 patients in both groups. Patients with vertical and horizontal bone loss were enrolled from the Department of Oral Medicine, Periodontology, and Oral Diagnosis of Ain Shams University and Misr International University. Bone augmentation procedures were performed using two techniques: autogenous bone block graft and xenograft bone block graft both with leukocyte-platelet rich fibrin (L-PRF). Results: Both autogenous and xenograft blocks in conjunction with L-PRF had a significant effect on vertical bone augmentation in cases of atrophic ridges in the esthetic region. Conclusion: Both autogenous and xenograft bone blocks in conjunction with L-PRF have a significant effect on vertical bone augmentation in cases of atrophic ridges in the esthetic region.

Atrophic Maxilla

The guided bone regeneration (GBR) technique has been used to achieve optimal bone volume augmentation and allow dental implant placement in atrophic maxilla and mandible, with predictable results and high survival rates. The use of bone substitutes has reduced the necessity of autogenous bone grafts, reducing the morbidity at the donor areas and thus improving the patients’ satisfaction and comfort. This clinical case report shows a clinical and histological evaluation of the bone tissue behavior, in a case that required the horizontal augmentation of the alveolar ridge, with the use of xenograft biomaterial and further dental implant placement. After six months of healing time, six implants were placed, and a bone biopsy was done. The histological analysis depicted some fragments of the xenograft bone graft, integrated with the new-formed bone tissue.

Bone Healing Process

AbstractPlatelet-rich plasma (PRP) has been shown to be a beneficial growth factor for bone tissue healing and is used in implantology. The aim of this study was to investigate the effects of PRP on bone defects in rabbits. Twenty rabbits were used to establish the implant bone defect model in this study. An intrabony defect (5mm × 5mm × 3mm) was created in alveolar bone in the lower jar of each rabbit. The wound was treated with PRP. The expression of platelet-derived growth factor BB (PDGFBB) was assessed by enzyme-linked immunosorbent assay (ELISA). Focal adhesion kinase (FAK) and related phosphatidylinositol 3-kinase (PI3K)/AKT (protein kinase B) levels were measured by Western blot. The results show that PRP could significantly improve the bone healing process when compared with control, and 10% PRP could markedly increase fibroblast proliferation 48-h post treatment. PDGFBB was higher in the PRP group than that in the control group. PRP treatment also could elevate the phosphorylation of FAK and PI3K/AKT, although the inhibitor of PDGFR could reverse this trend. These results suggest that PRP treatment improves the bone healing process through the FAK/PI3K/AKT pathway.

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

Bones and teeth are the only structureswithin the body where calciumandphosphate participate asfunctional pillars. Despite their mineralnature, both organs are vital and dynamic. The aim was to remark the indications for alveolar augmentation after tooth extraction and prior the placement of endoosseous dental implants. The autograft, allograft, alloplast, and xenograftmaterials all have reported success, alone or in combination,for particulate bone augmentation. Theparticulate autograft is the gold standard for mostcraniofacial bone grafting, including the treatmentof dental implant–related defects. Advantages of alveolar ridge augmentation with sufficient bone volume to adjust for uncompromised and esthetic implant placement, renders these procedures more than effective for majority of patients. Surgical reconstruction of the tissues and the procedure of ridge augmentation and subsequent placement of dental implant are necessary.

Abstract This clinical review is an evaluation of the effectiveness of the split ridge bone augmentation technique performed in the atrophic maxilla and mandible with buccolingual bony defects. The osseointegration success of implant placement in the area of split ridge bone augmentation is assessed and compared to implant success rates indicated in the literature. This evaluation includes 15 patients who were treated with alveolar split ridge bone augmentation at Tufts University School of Dental Medicine. During initial consultation, all patients were diagnosed with a buccolingual bone dimension of 3–5 mm on the edentulous alveolar crest. This bony buccolingual dimension was inadequate for placement of implants of desirable width and correct angulation as dictated by the prosthetic requirements. Crestal split augmentation technique involved a surgical osteotomy that was followed by alveolar crest split and augmentation after buccolingual bony plate expansion, prior to implantation. Implants were placed either immediately or 3 weeks after the initial augmentation. No fixation was used to stabilize the buccal bony cortex after the completion of the augmentation. All patients were placed on periodic follow-ups for a 24-month period postoperatively. Implant success was determined with the use of Buser's Criteria. In total, 33 implants were placed in 15 patients. The overall success rate of osseointegration of the endosseous implants placed in the area of split ridge bone augmentation was found to be 97%. One patient presented with facial bone resorption and implant mobility 4 months after the surgery. The implant was removed and the area was reconstructed with autogenous bone graft and later implanted with an endosseous implant. Our results indicate that the split crest bone augmentation technique is a valid reconstructive procedure that can be used to augment the buccolingual alveolar defect prior to implant placement providing good bone foundation for placement of implants with desirable width in favorable angulation. In comparison to traditional bone grafts techniques, crestal split ridge bone augmentation enables placement of dental implants immediately or 3 weeks after augmentation and eradicates the possible morbidity of the donor sites.

Abstract Objectives: This study evaluated the use of bone ring technique with xenogeneic bone grafts in treating horizontal alveolar bone defects. Material and methods: In total, 11 patients in need of horizontal bone augmentation treatment before implant placement were included in this retrospective study. All patients received simultaneous bone augmentation surgery and implant placement with xenogeneic bone ring grafts. We evaluated the postoperative efficacy of the bone ring technique with xenogeneic bone grafts using radiographical and clinical parameters. Results: Survival rates of implants were 100%. Cone-beam computed tomography revealed that the xenogeneic bone ring graft had significantly sufficient horizontal bone augmentation below the implant neck platform to 0 mm, 1mm, 2mm, and 3mm. It could also provide an excellent peri-implant tissue condition during the one-year follow-up after loading. Conclusion: The bone ring technique with xenogeneic bone ring graft could increase and maintain horizontal bone mass in the region of the implant neck platforms in serious horizontal bone defects.
