“…However, when it is not possible to install the dental implants simultaneously, cone beam computed tomography (CBCT) represents the best method for evaluating volumetric bone changes 21 . This examination offers three-dimensional (3D) visualization, allowing real volumetric measurements to be obtained during the bone healing phase 22 .…”

The aim of this study was to compare the volumetric changes and the new bone microarchitecture in human maxillary sinuses augmented with bioactive glass (Biogran) alone, bioactive glass combined with autogenous bone graft (1:1), or autogenous bone graft alone. Twelve maxillary sinuses were grafted with bioactive glass (group 1), nine with bioactive glass mixed with autogenous bone graft 1:1 (group 2), and 12 with autogenous bone graft (group 3). Patients underwent cone beam computed tomography 15days after the procedure to determine the initial volume of the graft (T1) and again 6 months later (T2). Biopsies were obtained at the time of dental implant placement and were subjected to micro-computed tomography. The volumetric change was 44.2% in group 1, 37.9% in group 2, and 45.7% in group 3 (P>0.05). The trabecular microarchitecture results showed that the materials used in groups 1 and 2 were good bone substitutes. However, the addition of 50% bioactive glass to autogenous bone graft improved the microarchitecture of the graft. Furthermore, the results for volumetric changes indicated that bioactive glass, its association with autogenous bone graft in a 1:1 ratio, and autogenous bone graft alone have similar resorption.

“…The risk of transmitting bacterial or viral infections undoubtedly exists, but it is markedly limited by the modern guidelines for bone procurement and processing. Moreover, presently the documented cases of bone allograft-linked infections are quite rare and certainly the risk is not greater than that posed by a blood derivative transfusion [14, 15, 17]. The banked bone has the advantages of unlimited availability and compatibility with future growth.…”

“…Unfortunately, at that age, the iliac crests are still cartilaginous [11]. The ribs can be easily fit to reconstruct the cranial convexity, but the aesthetic results (with the so-called washboard effect) may be unacceptable [12], reabsorption rates remain not negligible [2, 11, 13, 14], and very large defects cannot be repaired. Finally, young skulls are too thin to harvest large vault split-thickness bone grafts, and the reabsorption rate remains in the order of about 30% [2].…”

Transplant of Adult Bone for Reconstruction of a Large Post-Traumatic Cranial Defect in a Very Young Baby

Large cranial defects in very young patients are challenging. The ideal material for cranioplasty in this age group has not yet been identified. Cryopreserved autologous bone presents very high rates of failures, acrylic resins pose a number of compatibility problems, bioceramics may be contraindicated, and autografts may be not adequate for repair of large defects. We present an 18-month-old baby with a large post-traumatic cranial defect which was repaired by assembling a new bone flap on a sterile stereolithographic 3-D model. This customized newly assembled flap consisted of a scaffold of autologous bone (from vault duplication) sustaining 2 large grafts of homologous cadaveric bone. It was adequately modeled and contoured on the 3-D model using metallic plates and screws. Immediately after implantation on the skull, the metallic devices were progressively replaced by reabsorbable material, thus maintaining the previously obtained flap profile. In this paper we detail this original technique which was developed to manage this specific patient.

“…In the posterior maxilla cases, oroantral fistula and poor esthetical results might be additional unfortunate outcomes [7]. Implant placement in the posterior maxilla is often challenging due to limited bone volume availability [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Longer and broader implants may have a biomechanical advantage, leading to long-term survival [27].…”

Background and objectives: To evaluate whether sinus augmentation, using a minimally invasive implant device, via a non-submerged surgical approach, might negatively influence the outcome. Materials and Methods: A retrospective cohort study was conducted by evaluating patients’ files, classifying them into two groups. Fifty patients (22 men 28 women) were included in the study, 25 in each group. The use of an implant device based on residual alveolar ridge height for sinus augmentation, radiographic evaluation, insertion torque, membrane perforation, post-operative healing, and a minimum of 12 months follow-up were evaluated. Results: The mean residual alveolar ridge height was 5.4 mm for the non-submerged group and 4.2 mm for the submerged group. There were no intraoperative or postoperative complications (including membrane perforations). The mean insertion torque was 45 N/cm for the study group and 20 N/cm for the control group. Complete soft tissue healing was observed within three weeks. Mean bone gain height was 8 mm for the study and 9.3 mm for the control group. All implants osseointegrated after 6–9 months of healing time. Mean follow-up was 17.5 months, range 12–36 months. Marginal bone loss at last follow-up was not statistically significantly different: 1 mm in the non-submerged vs. 1.2 mm in the submerged group. Conclusions: Submerged and non-submerged healing following maxillary sinus augmentation was comparable provided residual alveolar ridge height >5 mm and insertion torque >25 N/cm.
