          Abstract

          RESUMEN Objetivos: Evaluar la estabilidad de osteosíntesis transmucosas, en casos de fracturas conminutas dentoalveolares, evitando la desperiostización de los fragmentos, para así mantener la vascularización de estos, favoreciendo la regeneración y pronóstico de las piezas dentarias y los segmentos óseos. Materiales y métodos: Se realizó osteosíntesis transmucosa con placas de perfil delgado (0,5 y 0,7 mm dePuy Synthes - Matrix Midface Kit) para la reducción de fracturas de procesos alveolares en 3 localizaciones de 2 pacientes que en asociación presentaban fracturas faciales complejas tratadas con reducción abierta y fijación interna convencional. Además se instalaron férulas con alambres de acero de 0,5 mm en los dientes involucrados. Resultados: Se logró una correcta reducción, corrección y fijación de los fragmentos y la conservación de dientes involucrados en las 3 localizaciones, observable tanto clínicamente como en las tomografías computarizadas a los 3 y 7 meses. Además, se retiraron las placas de osteosíntesis de forma ambulatoria y mediante anestesia local. Conclusiones: La estabilización y fijación con placas transmucosas favorece la consolidación de los segmentos afectados sin afectar el aporte vascular. Sin embargo, este método puede considerarse una medida de asistencia a la reducción abierta con fijación interna, que sigue siendo la medida de primera elección.

          ABSTRACT Objectives: To assess the stability of transmucosal osteosynthesis in cases of comminuted dentoalveolar fractures, avoiding the deperiostization of fragments to maintain their vascularization, favoring the regeneration and prognosis of dental pieces and bone segments. Materials and methods: Transmucosal osteosynthesis with low-profile plates (0.5 and 0.7 mm of Puy Synthes - Matrix Midface Kit) was performed to reduce fractures of alveolar processes in 3 locations of 2 patients, who in association had complex facial fractures treated with open reduction and conventional internal fixation. Furthermore, splints with 0.5 mm steel wires were installed on the teeth involved. Results: A correct reduction, correction, and fixation of the fragments and the preservation of teeth involved in the 3 locations, observable both clinically and in CT scans at 3 and 7 months was achieved. Besides, the osteosynthesis plates were removed on an outpatient basis and by local anesthesia. Conclusions: Stabilization and fixation with transmucosal plates favors the consolidation of the affected segments without affecting the vascular supply. However, this method can be considered an open reduction assistance measure with internal fixation, which remains the first-choice measure.

          Skeletal Cell Fate Decisions Within Periosteum and Bone Marrow During Bone Regeneration

          Bone repair requires the mobilization of adult skeletal stem cells/progenitors to allow deposition of cartilage and bone at the injury site. These stem cells/progenitors are believed to come from multiple sources including the bone marrow and the periosteum. The goal of this study was to establish the cellular contributions of bone marrow and periosteum to bone healing in vivo and to assess the effect of the tissue environment on cell differentiation within bone marrow and periosteum. Results show that periosteal injuries heal by endochondral ossification, whereas bone marrow injuries heal by intramembranous ossification, indicating that distinct cellular responses occur within these tissues during repair. Next, lineage analyses were used to track the fate of cells derived from periosteum, bone marrow, and endosteum, a subcompartment of the bone marrow. Skeletal progenitor cells were found to be recruited locally and concurrently from periosteum and/or bone marrow/endosteum during bone repair. Periosteum and bone marrow/endosteum both gave rise to osteoblasts, whereas the periosteum was the major source of chondrocytes. Finally, results show that intrinsic and environmental signals modulate cell fate decisions within these tissues. In conclusion, this study sheds light into the origins of skeletal stem cells/progenitors during bone regeneration and indicates that periosteum, endosteum, and bone marrow contain pools of stem cells/progenitors with distinct osteogenic and chondrogenic potentials that vary with the tissue environment.

            Periosteum: biology and applications in craniofacial bone regeneration.

            The bone-regenerative potentials of the periosteum have been explored as early as the 17th century. Over the past few years, however, much has been discovered in terms of the molecular and cellular mechanisms that control the periosteal contribution to bone regeneration. Lineage tracing analyses and knock-in transgenic mice have helped define the relative contributions of the periosteum and endosteum to bone regeneration. Additional studies have shed light on the critical roles that BMP, FGF, Hedgehog, Notch, PDGF, Wnt, and inflammation signaling have or may have in periosteal-mediated bone regeneration, fostering the path to novel approaches in bone-regenerative therapy. Thus, by examining the role that each pathway has in periosteal-mediated bone regeneration, in this review we analyze the status of the current research on the regenerative potential of the periosteum. The provided analysis aims to inform both clinician-scientists who may have interest in the current studies about the biology of the periosteum as well as dental surgeons who may find this review useful to perform periosteal-harnessing bone-regenerative procedures.

              Guidelines for the management of traumatic dental injuries. I. Fractures and luxations of permanent teeth.

              Crown fractures and luxations occur most frequently of all dental injuries. An appropriate treatment plan after an injury is important for a good prognosis. Guidelines are useful for delivering the best care possible in an efficient manner. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialties were included in the group. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion of the IADT board members. The guidelines represent the current best evidence, based on literature research and professional opinion. In this first article of three, the IADT Guidelines for management of fractures and luxations of permanent teeth will be presented.
