Block Bone Graft

The aim of the present study was to report the clinical case of a patient with a vertical defect of the alveolar ridge, which prevented the installation of dental implants without first treating the defect in question. A 32-year old female patient with a height defect of approximately 6 mm in the region of the missing absent teeth (13 and 14). The patient was treated using the sandwich osteotomy technique, with the interposition of a block bone graft of bovine origin. No complications were reported in the post- operative period. After seven months, two dental implants were installed in the relevant region. The bovine bone graft was incorporated into the relevant area. The bovine bone block graft used in this clinical case was shown to be a viable option for interposition between bone segments that have been osteotomized via sandwich osteotomy.

Immediate loading of full-arch prostheses on dental implants in the upper arch is challenging, as the bone is of low quality and obtaining sufficient torque may be difficult. The purpose of this case report is to describe the rehabilitation of a full-arch by means of placement of four internal tapered connection tilted implants and immediate loading. A 65-year-old man sought dental care with a partially edentulous upper arch. The teeth presented mobility and were extracted. In a second step, two conventional-length implants were placed in the anterior region and two tilted and nasal wall–directed extra-long implants in the posterior region. The insertion torques of 60 N.cm allowed the installation of an immediate prosthesis (hybrid). The clinical case report suggests that the placement of tilted and extra-long implants in the paranasal bone and immediate loading may be a viable option for rehabilitation of the edentulous upper arch.

The use of guided bone regeneration (GBR) has been gaining more and more ground in the field of implant dentistry, due to higher confidence in the materials available. As this is a highly versatile technique, the same biological basis-cell exclusion–can be used to treat any type of defect. Vertical augmentation in the alveolar ridge is currently treated by the GBR principle, predictably and with high success rates, using a rigid framework associated with a mix of hydroxyapatite and autogenous bone. Lyophilized bovine bone is the hydroxyapatite of choice for this condition because it allows bone volume to be maintained over a long period of time, due to its slow resorption. Another important char-acteristic found in hydroxyapatite is its porosity since it allows – in addition to graft neo-vascularization–a greater ease of cell adhesion when compared to crystalline materials. Thus, this clinical case presents the use (for the first time in the literature) of a vertical augmentation of an atrophic ridge using Criteria Lumina Bone Porous® as the hydroxy-apatite of choice for association with autogenous bone particles.

Block Bone Graft

In implantology, an increase in the bone thickness of the alveolar ridge is often associated with the use of autogenous bone, which is considered to be the gold standard. The aim of the present study was to report the clinical case of a patient with abnormal bone thickness in the alveolar ridge, causing severe esthetical damage, and the use of xenogeneic block bone grafts. A female, 43-year old patient exhibited a considerable bone defect in the region of teeth 11 (absent), although there was sufficient native bone available for the implantation. The patients treatment involved positioning the implant and performing a block bone graft using bone of bovine origin. The post-operative period passed without complications. The post-operative clinical examination confirmed the correction of the pre-existing esthetic defect and the health of the soft tissues involved. The tomographic examination 180 days post-surgery also confirmed an excellent increase in thickness. The bovine block bone graft used in the present case was shown to be viable in terms of correcting esthetic defects when there is sufficient native bone available for the implantation.

Maxillary Atrophy

Abstract Effectively restoring a grossly atrophic maxilla can be difficult for the implant surgeon. The placement of dental implants in patients who are edentulous in the posterior maxilla can present difficulties because of deficient posterior alveolar ridge and increased pneumatization of the maxillary sinus, resulting in a minimal hard tissue bed. Implant placement requires adequate quality and quantity of bone, especially in the posterior maxilla. Insufficient bone height and width in this area of the maxilla, because of expansion of the maxillary sinus and atrophic reduction of the alveolar ridge, represents a contraindication for conventional insertion of dental implants. The reconstruction of edentulous patients with adequate bone volume and density by the use of bone graft and, subsequently, the placement of dental implants has become a viable treatment option with high predictability. It is commonly shared that autologous bone graft is the gold standard grafting method in the augmentation of Higmoro antrum and in any kinds of guided bone regeneration. In this article, the authors report a case of severe maxillary atrophy that is augmented by block bone graft harvested from iliac crest. An early placement of implants is possible due to the quick healing of the site, as proven by histologic examinations.

Introduction. An autologous bone (bone derived from the patient himself) is considered to be a ?golden standard? in the treatment of bone defects and partial atrophic alveolar ridge. However, large defects and bone losses are difficult to restore in this manner, because extraction of large amounts of autologous tissue can cause donor-site problems. Alternatively, data from computed tomographic (CT) scan can be used to shape a precise 3D homologous bone block using a computer-aided design-computer-aided manufacturing (CAD-CAM) system. Case report. A 63-year old male patient referred to the Clinic of Dentistry of Vojvodina in Novi Sad, because of teeth loss in the right lateral region of the lower jaw. Clinical examination revealed a pronounced resorption of the residual ridge of the lower jaw in the aforementioned region, both horizontal and vertical. After clinical examination, the patient was referred for 3D cone beam (CB)CT scan that enables visualization of bony structures and accurate measurement of dimensions of the residual alveolar ridge. Considering the large extent of bone resorption, the required ridge augmentation was more than 3 mm in height and 2 mm in width along the length of some 2 cm, thus the use of granular material was excluded. After consulting prosthodontists and engineers from the Faculty of Technical Sciences in Novi Sad we decided to fabricate an individual (custom) bovine-derived bone graft designed according to the obtained 3D CBCT scan. Conclusion. Application of 3D CBCT images, computer-aided systems and software in manufacturing custom bone grafts represents the most recent method of guided bone regeneration. This method substantially reduces time of recovery and carries minimum risk of postoperative complications, yet the results fully satisfy the requirements of both the patient and the therapist.
