“…The computeraided design/computer-aided manufacturing workflow for modeling allows the preoperative definition of cutting paths and angles at the resection site and of the graft, as well as the shape of the osteosynthesis material. 185,186 This process can either be done via commercial platforms or the clinic itself, depending on the available resources. On the one hand, this increases accuracy and reduces operation times.…”

Reconstruction of significant maxillomandibular defects is a challenge that has been much discussed over the last few decades. Fundamental principles were developed decades ago (bone bed viability, graft immobilization). Clinical decision‐making criteria are highly relevant, including local/systemic factors and incision designs, the choice of material, grafting technique, and donor site morbidity. Stabilizing particulated grafts for defined defects—that is, via meshes or shells—might allow significant horizontal and vertical augmentation; the alternatives are onlay and inlay techniques. More significant defects might require extra orally harvested autologous bone blocks. The anterior iliac crest is often used for nonvascularized augmentation, whereas more extensive defects often require microvascular reconstruction. In those cases, the free fibula flap has become the standard of care. The development of alternatives is still ongoing (i.e., alloplastic reconstruction, zygomatic implants, obturators, distraction osteogenesis). Especially for these complex procedures, three‐dimensional planning tools enable facilitated planning and a surgical workflow.

“…This may be correlated to the predominantly being nature of the included patients in this study, where nine cases were resected for a benign cause, 2 posttraumatic defect malformation, and only one presented with malignant variant of ameloblastoma, Ameloblastic carcinoma. Dowgierd et al (2022) reported a predominant prevalence of Brown Class II defect in their study [26] .…”

Objective:The purpose of this study was to to outline the performance of low profile 2.4-mm reconstruction plate in bridging segmental mandibular defects. Materials and methods:The study is a randomized clinical trial with a one-year follow up period. Patients requiring segmental resection was divided into Group I, managed with a low-profile 2.4-mm reconstruction plate, and Group II, managed with a regular 2.7-mm reconstruction plate. A long-term follow-up session was performed to outline plate related complications. Results: Twelve patients were included in this study and divided into two groups, and at the end of the follow up period one patient failed to recall. None of the cases in the study group suffered from plate related complications, while two cases reported major and minor Plate related complications in the control group. Conclusion: a 2.4-mm reconstruction plate utilized in the fixation and reconstruction of a segmental mandibular defect offers a more convenient fixation device with a comparable favorable clinical and radiographic outcomes as the conventional reconstruction plate.

“…The following data were collected from each of the reports: (1) the name of the first author; (2) date of publication; (3) the name of the polymer used; (4) whether the polymer used was of natural or synthetic origin; (5) the name of the filler used; (6) the name of the PPh incorporated into the composite; (7) the PPhs group to which this particular compound belongs; (8) other additional composite components (if applicable); (9) the spatial structure of the composite (e.g., scaffold, film). The above-mentioned outcomes were analyzed only qualitatively, and in the absence of data in any of the domains, the field in the collective table was left blank, and at the synthesis stage, a given report was not taken into account in this specific domain.…”

“…Patients suffering from bone defects struggle not only with aesthetic but also functional problems that often prevent their daily functioning [1][2][3][4][5]. Depending on the type of defect, the range of possibilities includes prosthetic methods, bone block transplants and stimulation of bone regeneration [2,3,[6][7][8]. The dynamic development of prosthetics allows the creation of high-strength restorations with satisfactory function and aesthetics [6].…”

One of the possible alternatives for creating materials for the regeneration of bone tissue supporting comprehensive reconstruction is the incorporation of active substances whose controlled release will improve this process. This systematic review aimed to identify and synthesize in vitro studies that assess the suitability of polyphenolics as additives to polymer-ceramic composite bone regeneration materials. Data on experimental studies in terms of the difference in mechanical, wettability, cytocompatibility, antioxidant and anti-inflammatory properties of materials were synthesized. The obtained numerical data were compiled and analyzed in search of percentage changes of these parameters. The results of the systematic review were based on data from forty-six studies presented in nineteen articles. The addition of polyphenolic compounds to composite materials for bone regeneration improved the cytocompatibility and increased the activity of early markers of osteoblast differentiation, indicating a high osteoinductive potential of the materials. Polyphenolic compounds incorporated into the materials presumably give them high antioxidant properties and reduce the production of reactive oxygen species in macrophage cells, implying anti-inflammatory activity. The evidence was limited by the number of missing data and the heterogeneity of the data.
