Influencia de la respiración en el desarrollo del maxilar superior
Breathing is a vital process; it can affect craniofacial development, particularly that of the maxilla. This literature review analyzes the relationship between breathing patterns and maxillary development. Numerous studies have shown that chronic mouth breathing in early life is associated with morphological alterations of the maxilla, such as narrow palate, malocclusions, and lingual postural changes. It is concluded that early diagnosis and an interdisciplinary approach are essential to prevent structural and functional alterations.
From the mouth to the body: The role of periodontal disease in overall health
Periodontal disease is a chronic bacterial condition that affects both the supporting and protective tissues of the teeth. Globally, it shows a high prevalence, and in Argentina, studies have demonstrated that 96.8% of the adult population presents some degree of gingival pathology, while approximately 14.3% requires complex periodontal treatment, according to the Argentine Society of Periodontology. Given this scenario, the main challenge is to provide treatment tailored to each patient’s needs. Public health programs that incorporate effective preventive strategies and oral health promotion, as well as coordinated efforts among governmental bodies, healthcare systems, and academic institutions, are essential. Within this framework, the routine implementation of the Basic Periodontal Examination plays a key role. This tool allows for rapid identification of periodontal status, guides clinicians regarding the need for further diagnostic procedures, and facilitates appropriate clinical decision-making for individualized treatment planning.
Avulsion and Reimplantation of a Maxillary Central Incisor During Orthodontic Treatment
A clinical case is presented with a diagnosis of retained tooth. During the course of the treatment,the patient suffered a traumatic avulsion of an Upper Central Incisor,the presence of the vestibular arch is essencial in the following process of reimplantation(1) and stabilization of the traumatized tooth.

Carcinoma de células escamosas en lengua. Reporte de un caso clínico
Squamous cell carcinoma (SCC), a malignant neoplasm derived from squamous epithelium, accounts for 90 to 94% of oral cavity cancers. Fifty percent of intraoral SCC lesions are located on the tongue, primarily along the lateral borders. Therefore, it is uncommon to find it in areas such as the junction of the tongue and the floor of the mouth, or on the dorsum of the tongue. We present the clinical case of a squamous cell carcinoma of the tongue border in a 57-year-old male patient with a history of substance abuse and dental trauma. The diagnosis was made based on the clinical lesions and confirmed by histopathology.
Metrology of dental models manufactured by 3d printers in horizontal and vertical positions
The aim of this study was to analyze variations in the 3D dimensional accuracy of dental models manufactured by additive manufacturing, evaluating the influence of horizontal versus vertical printing orientation on the build platform. A single digital STL file (SETUP1), generated with Orchestrate3D orthodontic planning software, was used. From this file, 80 models were fabricated using 3D printing: 40 with horizontal orientation and 40 with vertical orientation. The analysis of dimensional accuracy seeks to provide clinicians with objective criteria on the reliability of the reproduction process to support the choice of the most appropriate orientation according to the requirements of each dental discipline. The physical models were digitized using the Carestream CS 3600 intraoral scanner and the files were imported into Geomagic Control X (Cx). Using a best-fit algorithm, the digitized meshes were superimposed on the original master file (SETUP1) for structural comparison. The results established a correlation between dimensional accuracy and printing orientation. Horizontally printed models exhibited greater accuracy than vertically printed ones. The average accuracy of vertical models was below 67%, while that of horizontal models exceeded this threshold.
Predicción de la impactación de caninos superiores basada en su posición intraósea.
This study examined the influence of the intraosseous position of permanent maxillary canines on their ability to erupt normally or become impacted. A literature review was conducted using Google Scholar (https://scholar.google.com/) to find information on risk factors, etiology, clinical consequences, and management strategies for canine impaction. A retrospective observational design was used, selecting previous studies that addressed the prediction of maxillary canine impaction using panoramic radiographs and other radiological measurements. The sector definition developed by Ericson and Kurol in 1988, as modified by Lindauer et al. in 1992, was applied to classify the position of impacted canines. Patients who began treatment in 2022 at the Interceptive Orthodontics Clinic of the Argentine Dental Association (CAO) were included. The inclusion criteria were patients under 12 years of age with erupted first molars and maxillary incisors and unerupted canines and premolars. Patients with prior maxillofacial surgery, significant dental trauma, or systemic conditions affecting tooth eruption were excluded. Preliminary findings suggest that the canine position in relation to the sectors defined by Lindauer et al. provides a useful classification for predicting impaction. Evaluating the maxillary canine position in relation to the root of the maxillary lateral incisor on panoramic radiographs is fundamental for the diagnosis and management of impaction. The sectorbased classification offers a practical tool for identifying at-risk patients, facilitating early intervention.
Disyunción realizada con MARPE (miniscrew assisted rapid palatal expander): guía para aplicar la técnica y reporte de un caso clínico.
In the three-dimensional planning of orthodontic treatment, the transverse problem should be prioritized. When a skeletal transverse maxillary deficiency is diagnosed, rapid maxillary expansion is the preferred treatment. A thorough understanding of its scope and limitations— considering the patient's age, the stage of facial suture closure, and appropriate anchorage —leads to proper execution and optimal results. Nowadays, thanks to two advanced tools, cone-beam computed tomography (CBCT) and microimplants, the age range for applying this technique has been broadened. CBCT allows for a three-dimensional diagnosis of the midpalatal suture, indicating its ossification degree and quantifying transverse discrepancy from stable bone points. The use of microimplants provides biomechanical advantages by minimizing unwanted tooth movement due to osseous anchorage, resulting in more effective and efficient treatment. This article reports the case of a 17-year-old male patient diagnosed with a collapsed maxilla and a stage C intermaxillary suture according to the Angelieri Method (AM), treated with a metallic device with an expansion screw anchored to two palatal microimplants, achieving a positive widening of the maxilla.
Un tumor de dos caras: reporte de un raro ameloblastoma híbrido de evolución inusual.
Ameloblastoma is a benign odontogenic epithelial tumor characterized by a high recurrence rate. It is locally aggressive and exhibits unlimited growth potential. The molecular and genetic factors underlying the oncogenic transformation of odontogenic epithelium into ameloblastoma are strongly associated with the deregulation of multiple genes. Approximately 80% of ameloblastomas arise in the molar and mandibular ramus regions, whereas about 20% occur in the posterior maxilla. This report describes a case of hybrid ameloblastoma in an uncommon location in a 76-yearold man with a 20-year clinical history.

Pulpectomía no instrumentada en piezas primarias.
El presente artículo muestra la aplicación del concepto LSTR (Lesion Sterilization and Tissue Repair) como alternativa mínimamente invasiva para el tratamiento endodóntico en dientes primarios, especialmente útil en niños pequeños o no cooperadores. Se destaca que el diagnóstico pulpar en pacientes pediátricos es complejo debido a la dificultad para diferenciar pulpitis reversible e irreversible, por la subjetividad de los síntomas y las limitaciones comunicativas del niño. La técnica NIET (pulpectomía no instrumentada), basada en LSTR, permite esterilizar los conductos exclusivamente mediante irrigación y la aplicación de pastas antibióticas como CTZ o 3Mix-Hoshino, ambas con alta efectividad en piezas necróticas. Estas terapias reducen el tiempo clínico facilitando así el manejo de pacientes difíciles. El artículo incluye un caso clínico con pasta CTZ y concluye que el éxito terapéutico depende de un diagnóstico preciso y un sellado coronal adecuado.
