- ÍtemActividad de la corteza cerebral en niños con mordida abierta anterior(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Odontología, Medellín y Envigado, 2019-10-17) Zuluaga, Carolina; Estrada, Natalia; Jiménez, Kelly; Restrepo, Claudia; Botero, Paola; Botero, Paola; Restrepo, ClaudiaIntroduction: Anterior Open Bite (AOB) is a malocclusion, associated with alterations in tongue´s position and/or function, which are highly regulated by the brain cortex. Objective: The aim of this case and control study was to determine the activity of the brain cortex of children with AOB and normal vertical overlap (NVO) at rest and during phonation and deglutition. Design: Thirthy three children (16 with AOB and 17 with NVO) in mixed dentition from 8-11 years old (mean age 9,2 years old), recruited from public schools of Envigado, underwent a brain mapping that was performed by quantitative electroencephalography (QEEG) during tongue rest, deglutition and phonation. The children were also evaluated by a phonoaudiology, to determine if the AOB affects motor process of phonoarticulating organs, breathing and phonation. Data were analyzed using the U Mann-Whitney test and T Student. Results: Higher brain cortex activity was found during the rest position of the tongue, in children with AOB (p<0.05) when compared with children with NVO. Conclusion: The brain cortex has an important role in the regulation of tongue functions and position at rest. To our knowledge, this is the first study that uses QEEG and shows that brain activity in subjects with AOB is higher than in subjects with NVO at rest and that this could be related to an altered tongue position.

- ÍtemAlteraciones del habla en pacientes menores de doce años tratados con aparatos que contengan paladar acrílico(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Ortodoncia, Bogotá, 2021-01-10) Niño Espitia, claudia Marcela; Perdomo ortiz, Hector Davian; Casallas Fraile, Nestor Alberto; Benavides Pinto, Berta Cecilia; Hurtado Santanilla, Martha Elena; Ruiz Gómez, AdielaOne way to treat malocclusions at an early age is by means of functional orthopedic devices, which are bimaxillary anchorage and do not depend exclusively on dental support, they are made up mostly of an acrylic body that is in direct contact with the hard palate, protrusion springs, retention hooks, expansion screws, upper and lower vestibular arches of the Bimler, Eschler or Hawley type, among others. Removable orthopedic appliances with acrylic palate are widely used in the treatment of malocclusions and bone discrepancies in children under 12 years of age. In the literature it has been found that appliances can influence articulation failure of sound production causing dyslalias; these can have varying degrees of severity in speech sound disturbances; resulting in communication failures. A bibliographic review was carried out in Spanish and English, between the years 2010 to 2020, in various sources of digital information and bibliographic databases such as Science direct, Pubmed, Cochrane library, Proquest and the academic Google search engine, in which the advanced search strategy. The present analysis covered 56 publications from the years 2012 to 2018, about the speech disturbances in patients under 12 years old treated with appliances containing acrylic palate. Based on the literature review, it can be affirmed that when using this type of orthopedic device during early treatment, several phonemes can be altered, where several authors affirm that reducing acrylic on the palate could reduce these alterations as long as there is a good adaptation and a follow-up by the stages.

Dental arch dimensions wereassessed through digitalized study models. Swallowing was evaluated using the Payne technique,and phoniatric assessment included an adaptation of the articulation test used to describe pho-nemes. Statistical analysis: Chi-Square or Fisher's exact test for comparisons between qualitativevariables and the Mann Whitney or T-student were applied to compare the dental arch dimensionsaccording to bite type. A logistic regression model was applied to control the effect of confusionbetween independent variables and to describe its simultaneous effect on the type of bite.Results > Intercanine, interpremolar and intermolar widths showed higher values in AOB patientswith a mean deviation (MD) of 0.536 (P = 0.031), 0.60 (P = 0.043) and 1.15, (P < 0.001) respec-tively. Distortions caused by tongue interposition and thrust, tongue protrusion during swallowing,mandibular arch intermolar width, total maxillary arch length, maxillary arch perimeter, andposterior arch depth accounted for 64.6% of AOB and allowed for correct predictions in 83.8% ofthe cases observed in the study population.

- ÍtemAssessment of Streptococcus Mutans Adhesion to the Surface of Biomimetically-Modified Orthodontic Archwires(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Odontología, Medellín y Envigado, 2020-02-26) Arango-Santander, Santiago; Gonzalez Velez, Carolina; Aguilar Villada, Anizac Andrea; Cano Melguizo, Alejandro; Castro Florez, Sergio; Sanchez Garzon, Juliana; Franco, John; Arango-Santander, SantiagoBacterial adhesion and biofilm formation on the surfaces of dental and orthodontic biomaterials is primary responsible for oral diseases and biomaterial deterioration. A number of alternatives to reduce bacterial adhesion to biomaterials, including surface modification using a variety of techniques, has been proposed. Even though surface modification has demonstrated a reduction in bacterial adhesion, information on surface modification and biomimetics to reduce bacterial adhesion to a surface is scarce. Therefore, the main objective of this work was to assess bacterial adhesion to orthodontic archwires that were modified following a biomimetic approach. The sample consisted of 0.017 × 0.025, 10 mm-long 316L stainless steel and NiTi orthodontic archwire fragments. For soft lithography, a polydimethylsiloxane (PDMS) stamp was obtained after duplicating the surface of Colocasia esculenta (L) Schott leaves. Topography transfer to the archwires was performed using silica sol. Surface hydrophobicity was assessed by contact angle and surface roughness by atomic force microscopy. Bacterial adhesion was evaluated using Streptococcus mutans. The topography of the Colocasia esculenta (L) Schott leaf was successfully transferred to the surface of the archwires. Contact angle and roughness between modified and unmodified archwire surfaces was statistically significant. A statistically significant reduction in Streptococcus mutans adhesion to modified archwires was also observed.
- ÍtemAutotransplantes dentales y ortodoncia. Una revisión desde lo básico hasta los prototipos personalizados 3D(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Odontología, Medellín y Envigado, 2019-08-13) González Vélez, Carolina; Villa Molina, Jorge Andres
- ÍtemBioinspired Topographic Surface Modification of Biomaterials(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Odontología, Medellín y Envigado, 2022-03-24) Arango-Santander, SantiagoPhysical surface modification is an approach that has been investigated over the last decade to reduce bacterial adhesion and improve cell attachment to biomaterials. Many techniques have been reported to modify surfaces, including the use of natural sources as inspiration to fabricate topographies on artificial surfaces. Biomimetics is a tool to take advantage of nature to solve human problems. Physical surface modification using animal and vegetal topographies as inspiration to reduce bacterial adhesion and improve cell attachment has been investigated in the last years, and the results have been very promising. However, just a few animal and plant surfaces have been used to modify the surface of biomaterials with these objectives, and only a small number of bacterial species and cell types have been tested. The purpose of this review is to present the most current results on topographic surface modification using animal and plant surfaces as inspiration to modify the surface of biomedical materials with the objective of reducing bacterial adhesion and improving cell behavior

- ÍtemCambios del ángulo funcional masticatorio a los seis meses de tratamiento con aparatos de ortopedia funcional: descriptivo longitudinal(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Especialización en Ortodoncia, Bogotá, 2019-11-29) Aristizábal Vargas, Anny Julieth; Ariza Méndez, Julieth Alejandra; Flórez Carvajal, Angela Patricia; Hurtado Santanilla, Martha Elena; Ruíz Gómez, AdielaThe functional masticatory angle is a record taken by performing lateral movements, when a contact between upper and lower canine teeth vertices on the same side is produced; the angle that is formed through these movements is measured to determine a correct chewing and the minimum vertical dimension of occlusion. Objective: to compare changes in the functional masticatory angle after six months of treatment with functional orthopaedic appliances in children treated in the periods II-2018 and I-2019 at the orthopaedics clinic of the University “Cooperativa de Colombia”, Bogotá headquarters. Materials and methods: longitudinal descriptive study of the masticatory functional angle in intraoral photographs of patients; changes T0 to T1 are measured in degrees, six months after the begining of the treatment; Chi-square test and t-Student was applied to identify the percentage distribution differences of the condition of the masticatory functional angle between boys and girls. The t-Student test was also implemented to compare the averages of the differences in the masticatory functional angle between boys and girls. Results: Nineteen subjects were evaluated, twelve girls and seven boys, average age 8 years (standard deviation ± 2.1), the distribution of orthopaedics instruments showed a higher percentage for Klammt Class I Open Activator with 47.3% and lower proportion Network System SN3 and Tracks Indirect flat 5.2% respectively. No significant statistical differences were found in the masticatory functional angle between boys and girls (p> 0.05), for the difference of the right and left sides the girls showed balance (13.3%) and boys (25%). Conclusions: No significant statistical differences between boys and girls were identified neither in the initial and final time, nor in each sex and the total population due to treatment effect (p> 0.05).
- ÍtemCambios dentales y cefalometricos en pacientes tratados con advansync® y/o herbsts®. posteriores a la finalización(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Especialización en Ortodoncia, Bogotá, 2019-12-03) Morales Meza, Michael Ándres; Ríos Serrato, Milton David; Arango Roncallo, Steven; Perdomo Ospina, Andrés FélipeThere are several fixed and removable mandibular advancement devices for correction of class II malocclusion. It is important to determine the post-treatment stability of this apparatus to assess whether they are effective treatments over time. Objective: To evaluate cephalometric, sagittal and vertical changes in patients with class II malocclusion due to mandibular retrognathism, treated with Advansync® and / or Herbst, after 18 months after removing the mandibular propellant. Materials and methods: 10 patients who were part of an ECA study were evaluated, consisting of 75 patients treated with Advansync and / or Herbst mandibular thrusters, aged between 14 and 36 years, who attended the specialty of Orthodontics between 2013 and 2018 the Dental Clinic of the Cooperative University of Colombia, Bogotá headquarters. Profile radiographs were taken before treatment, after removal of mandibular advancement apparatus and post-treatment follow-up. The points and measurement planes of the different variables were drawn with the Dolphin Imaging 11.7 Premium program. Sixteen sagittal and vertical skeletal variables were measured to determine the stability of patients treated with mandibular thrusters. To check the significance of the data, the t-student test (p <0.05) was used. Results: The post-treatment stability with mandibular thrusters was 86.5%, without considering the variable (FH-MP), which presented a percentage of negative stability. Conclusion: The treatment of patients with class II malocclusion with Advansync and / or Herbst mandibular thrusters in adults showed good stability considering that stable when more than 80% of the results obtained in the treatment are maintained in the observation period. However, more scientific evidence is needed on the stability of class II malocclusion treatments treated with Advansync and / or Herbst in the long term.
- ÍtemCambios en el rendimiento masticatorio con el tratamiento de ortodoncia y ortopedia maxilar(Universidad Cooperativa de Colombia, Posgrado, Especialización Ortodoncia, Bogotá, 2021-02-19) Corredor Bustos, Leidy Zamira; Lema Sanabria, Cindy Johana; Rodriguez Robayo, Emanuel Johanson; Benavides Pinto, Berta Cecilia; Ruiz Gomez, AdielaDental malocclusion occupies the third most prevalent place in the pathologies of the stomatognathic system, it is one of the most frequent reasons for consultation in orthodontics and orthopedics; the relationship between malocclusion and chewing has been widely studied, because the chewing process is a complex task influenced by factors with a great impact on people's quality of life; To evaluate the degree of crushing of food, chewing performance has been used, which has made it possible to demonstrate how the masticatory function is affected by dental malocclusions, especially in the masticatory process, because these patients do not crush food in a adequate, so it generates higher energy expenditure at the gastric level, leading to gastrointestinal disorders, obesity and heart problems, among others. A bibliographic review was carried out in Spanish and English, between the years 2010 to 2020, in various sources of digital information and bibliographic databases such as Sciencie direct, Pubmed, Cochrane library, Proquest and the academic Google search engine, in which the advanced search strategy. The present analysis covered 19 publications, exploring changes in chewing performance after orthodontic and maxillary orthopedic treatment. Based on the literature review, it can be stated that the chewing performance is influenced by the type of malocclusion; the activity of the chewing muscles during mastication is less coordinated in class III malocclusion than in class II malocclusion; Orthodontic and maxillary orthopedic treatments balance the musculoskeletal structures during their masticatory function and therefore improve masticatory performance.
- ÍtemCambios en la dimensión transversal utilizando aparatología fija convencional(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Especialización en Ortodoncia, Medellín y Envigado, 2022-11-29) Guisao Álvarez, Diana María; Echeverri Echeverri, Néstor Javier; Echeverri Echeverri, Néstor Javier; Marín Palacio, HaroldThe purpose of this study was to evaluate the dimensional changes, incisor inclination and relief of crowding during treatment with conventional brackets in a 14-year-old female patient with a Class II skeletal pattern, vertical rotation with anterior vertical excess, Class II malocclusion with anterior open bite, severe crowding and transverse collapse of the arches. Bimaxillary orthodontic treatment was performed with conventional Roth slot 0.022 brackets, a sequence of archwires was started from NiTi 0.012, to Stainless Steel 0.017X0.025, NiTi archwires were also used for arch expansion at the beginning of the alignment phase. In the working and finishing phase, intermaxillary elastics were used for coupling. Bimaxillary orthodontic treatment was carried out for approximately 18 months, 15 effective appointments where significant changes in alignment, relief of crowding and transverse dimensions of the arches were obtained with a conventional orthodontic technique. It was concluded that satisfactory results can be obtained in the treatment of complex malocclusions with conventional orthodontic techniques, using adequate technique and biomechanics and also with the good collaboration of the patient, with respect to appointments kept, use of intermaxillary elastics and feeding to avoid dropping of attachments.

- ÍtemCambios En Las Dimensiones De Las Vias Aereas Superiores Generados Por Tratamientos De Ortodoncia(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Especialización en Ortodoncia, Pasto, 2020-06-16) Cuellar Torres, Esteban Rodrigo; Eraso Rodríguez, Alirio Fernando; Calderón Moncayo, Luis Fernando; Salas Zambrano, Luis AndrésThe upper area of the respiratory system is called the upper airway (VAS), the nasal cavity corresponds to the first portion of the airway and is a common space between the skull and the face. This cavity is made up of two parts, an anterior area called the nose or nasal pyramid and the posterior one, the nostrils. We also find the pharyngeal space or pharynx, which is the part of the digestive tract and the respiratory tract that forms the link between the nasal and oral cavities, on the one hand, and the esophagus and larynx, on the other. It extends from the base of the skull to the level of the VI - VII cervical vertebrae
