Item Autogenous Dentin Graft in Bone Defects after Lower Third Molar Extraction: A Split-Mouth Clinical Trial(Materials, 2020) Sánchez Labrador, Luis; Martín Ares, María; Ortega Aranegui, Ricardo; López-Quiles Martínez, Juan; Martínez González, José MaríaVarious biomaterials are currently used for bone regeneration, with autogenous bone being considered the gold standard material because of its osteogenic, osteoconductive, and osteoinductive properties. In recent years, the use of autogenous dentin as a graft material has been described. This split-mouth clinical trial assesses the efficacy of autogenous dentin for the regeneration of periodontal defects caused by bone loss associated with impacted lower third molar extraction. Fifteen patients underwent bilateral extraction surgery (30 third molars) using dentin as a graft material on the test side, and leaving the control side to heal spontaneously, comparing the evolution of the defects by evaluating probing depth at three and six months post-operatively. Bone density and alveolar bone crest maintenance were also evaluated six months after surgery, and pain, inflammation, mouth opening capacity on the second and seventh days after surgery. Probing depth, radiographic bone density, and alveolar bone crest maintenance showed significant differences between the test and control sides. Autogenous dentin was found to be an effective biomaterial for bone regeneration after impacted lower third molar extraction.- Project number: 292

Item Development of a program of mixed radiolucent-radiopaque lesions imaging via radiographic cases for active learning in oral medicine(2017) López-Pintor Muñoz, Rosa María; Hernández Vallejo, Gonzalo; Ortega Aranegui, Ricardo; Paredes Rodríguez, Víctor Manuel; de Arriba de la Fuente, Lorenzo; Casañas Gil, Elisabeth; Ramírez Martínez-Acitores, Lucia; Serrano Valle, JuliaA través del presente proyecto se ha creado un fichero de imágenes radiográficas mixtas (radiopacas-radiolucidas) que serán utilizadas por los alumnos del tercer curso de Grado de la asignatura Medicina Bucal a fin de mejorar la enseñanza práctica del apartado lesiones radiográficas de los maxilares. Dichos ficheros se incorporarán al Campus Virtual para que el alumno pueda hacer uso de ellos. La elaboración de un fichero de estas características ha exigido en primer lugar la selección de las imágenes radiográficas mixtas de los maxilares más representativas. Se han seleccionado 43 imágenes radiográficas mixtas que se han clasificado en “Mixed Radiolucent-Radiopaque periapical lesions” (15 imágenes), “Mixed Radiolucent-Radiopaque pericoronal lesions” (8 imágenes) y “Mixed Radiolucent-Radiopaque lesions not necessarily contacting teeth“ ( 20 imágenes). Se han realizado 4 flowchart (el tercer grupo se subdividió en dos) para esquematizar las lesiones mixtas más frecuentes con sus características clínicas y radiográficas más habituales. Dichos flowchart ayudarán al alumno a poder llegar al diagnóstico de las lesiones de los casos clínicos seleccionados, cuya historia clínica también se ha reflejado. Todo el trabajo se ha realizado en dos idiomas inglés y español, que ayudará a los alumnos a aprender el vocabulario en inglés relacionado con el tema. Además, facilitará la comprensión de los alumnos de otras nacionalidades que pueden acudir a nuestra facultad y ayudará a los alumnos de la UCM que acuden a otras universidades Europeas o Americanas. Item Maxillary growth in a congenital cleft palate canine model for surgical research(Journal of Cranio-Maxillofacial Surgery, 2014) Paradas Lara, Irene; Casado Gómez, Inmaculada; Martín, Conchita; Martínez Sanz, Elena; López Gordillo, Yamila; González, Pablo; Rodríguez Bobada, Cruz; Chamorro, Manuel; Arias, Pablo; Maldonado Bautista, Estela; Ortega Aranegui, Ricardo; Berenguer, Beatriz; Martínez Álvarez, María ConcepciónWe have recently presented the Old Spanish Pointer dog, with a 15-20% spontaneous congenital cleft palate rate, as a unique experimental model of this disease. This study aimed to describe the cleft palate of these dogs for surgical research purposes and to determine whether congenital cleft palate influences maxillofacial growth. Seven newborn Old Spanish Pointer dogs of both sexes, comprising a cleft palate group (n = 4) and a normal palate group (n = 3), were fed using the same technique. Macroscopic photographs and plaster casts from the palate, lateral radiographs and computer tomograms of the skull were taken sequentially over 41 weeks, starting at week 5. The cleft morphology, the size and the tissue characteristics in these dogs resembled the human cleft better than current available animal models. During growth, the cleft width varies. Most of the transverse and longitudinal measures of the palate were statistically lower in the cleft palate group. The cleft palate group showed hypoplasia of the naso-maxillary complex. This model of congenital cleft palate seems suitable for surgical research purposes. A reduced maxillofacial pre- and post-natal development is associated to the congenital cleft palate in the Old Spanish Pointer dog.Item In vitro comparison of primary stability of two implant designs in D3 bone(Med Oral Patol Oral Cir Bucal, 2017) González Serrano, José; Ortega Aranegui, Ricardo; López-Quiles Martínez, JuanBackground: Primary stability (PS) is a key factor for implant survival rate and depends on implant design or bone quality. The aim of this study was to compare different thread designs implants, evaluating PS with periotest values (PV) and implant stability quotient (ISQ) values through resonance frequency analysis (RFA). Material and methods: A total of 60 implants (Radhex®, Inmet-Garnick S.A., Guadalajara, Spain) were placed in freshly bovine ribs in vitro. Two designs were used: 30 tapered body with single thread design (PHI) and 30 tapered body with double thread design implants (PHIA). Both designs were 4mm wide and 12mm long. Implants were placed according to manufacturer's guidelines. Osstell™ and Periotest® devices were used to evaluate PS by a blinded independent observer. Computed tomographies (CTs) of the ribs were made (BrightSpeed Series CT systems, GE Healthcare, Milwaukee, WI, USA) and bone quality surrounding each implant was evaluated in Hounsfield Units (HU) using Ez3D Plus software (Vatech Co., Korea). Bone quality was classified according to Misch and Kircos in D1, D2, D3 or D4. Results: All implants were mechanically stable. Only implants placed in D3 bone (350-850 HU) were selected for the study: 28 PHI and 26 PHIA. The one way ANOVA showed significant difference (p < 0.005) among two implants designs in ISQ values (61,55 ± 6,67 in PHI and 68,94 ± 5,82 in PHIA). No significant difference (p = 0,171) was shown in PV between two designs (-4,47 ± 1,39 in PHI and -4,77 ± 0,87 in PHIA). Conclusions: Higher PS was found using Osstell™ device in implants with double thread design (PHIA) in comparison to implants with single thread design (PHI) in D3 bone.Item A cephalometric method to diagnosis the craniovertebral junction abnormalities in osteogenesis imperfecta patients(Journal of Clinical Experimental Dentistry, 2015) Rios Rodenas, Mercedes; Nova García, Manuel Joaquín De; Gutiérrez Díez, Mª Pilar; Feijoo García, Gonzalo; Mourelle Martínez, Rosa; Garcilazo Ambriz, Mario; Ortega Aranegui, RicardoOsteogenesis imperfecta (OI) is a hereditary bone fragility disorder that in most patients is caused by mutations affecting collagen type I. Their typical oral and craneofacial characteristics (Dentinogenesis imperfecta type I and class III malocclusion), involve the dentist in the multidisciplinary team that treat these patients. It is usual to perform lateral skull radiographs for the orthodontic diagnosis. In addition, this radiograph is useful to analyse the junctional area between skull base and spine, that could be damaged in OI. Pathology in the craneovertebral junction (CVJ) is a serious complication of OI with a prevalence ranging from rare to 37%. To diagnosis early skull base anomalies in these patients, previously the neurological symptoms have been appear, we make a simple cephalometric analysis of the CVJ. This method has four measurements and one angle. Once we calculate the values of the OI patient, we compare the result with the mean and the standard deviations of an age-appropriate average in healthy controls. If the patient has a result more than 2,5 SDs above the age appropriate average in healthy controls, we should to refer the patient to his/her pediatrician or neurologist. These doctors have to consider acquiring another diagnostic images to be used to determine cranial base measurements with more reliability. Thereby, dentists who treat these patients, must be aware of the normal radiological anatomy of the cervical spine on the lateral cephalogram.Item Maxillary sinus balloon lifting and deferred implantation of 50 osseointegrated implants: a prospective, observational, non-controlled study(International Journal of Oral and Maxillofacial Surgery, 2018) López-Quiles Martínez, Juan; Melero-Alarcón, C.; Cano-Durán JA; Sánchez-Martínez-Sauceda EI; Ortega Aranegui, RicardoThe aim of this study was to assess the effectiveness of minimally invasive antral membrane balloon elevation (MIAMBE). Twenty-seven patients with severe resorption of the posterior maxilla were treated by balloon catheter-assisted sinus lift procedure with deferred implant placement. Panoramic radiographs and computed tomography scans were obtained prior to surgery and at 6 months after surgery, before implantation. Data collected following surgery included inflammation, pain, bleeding, infection, and haematoma. Pain and inflammation were recorded using a six-point verbal rating scale (VRS). The patients were followed up for an average of 15 months. The initial sinus floor height was measured for each planned implant and compared with the height at 6 months post-surgery. The average bone height gain was 8.10 ± 3.45 mm (range 0.5–13.95 mm). Inflammation on the VRS ranged from 0 to 3 (mean 0.97 ± 0.85), while pain ranged from 0 to 4 (mean 0.87 ± 1.19). There was a perforation of the Schneiderian membrane smaller than 2 mm in one case. In another case, the balloon lift procedure had to be aborted and changed to the conventional Tatum technique due to breakage of the balloon inside the sinus. The results of this study show the balloon sinus lift technique to be an easy procedure to perform, with apparently low rates of inflammation and pain, and to provide sufficient quantity and quality of bone for the placement of osseointegrated implants.- Project number: 397
Item Empleo de la tomografía computerizada para la adquisición de modelos preclínicos reales para el entrenamiento de los estudiantes en el manejo de complicaciones surgidas a partir de traumatismos dentales(2023) Arias Paniagua, Ana María; Gancedo Caravia, Lucía; Bascones Ilundain, Jaime Antonio; Montero Martínez, Antonio; Ortega Aranegui, Ricardo; Herrera Martín, Ángel; Riaza Solís, Paula; Ruiz González, Rocío; Cortines Arteaga, María PilarEste proyecto propone una solución sostenible para el entrenamiento preclínico de los alumnos y la adquisición de habilidades ante complicaciones reales producidas por traumatismos dentales. - Project number: 276
Item Development of a program of radiopaque lesions images via radiographic cases for active learning in oral medicine(2016) Hernández Vallejo, Gonzalo; López-Pintor Muñoz, Rosa María; Ortega Aranegui, Ricardo; Paredes Rodriguez, Víctor; Casañas Gil, Elisabeth; de Arriba de la Fuente, LorenzoThrough the creation of this project in English, we have made a file of radiographic images that will be used by third year dental students in order to improve the practical teaching part of the subject of Oral Medicine, essentially by incorporating these files to the Virtual Campus. We have selected the most representative radiopaque radiographic images studied in pathology lectures given. We have prepared a file with 59 radiopaque radiographic images. These lesions have been divided according to their relationship and number with the tooth, into the following groups: “Anatomic radiopacities”, “Periapical radiopacities”, “Solitary radiopacities not necessarily contacting teeth”,“Multiple separate radiopacities”, and “Generalized radiopacities”. We created 4 flowcharts synthesizing the mayor explanatory bases of each pathological process in relation to other pathologies within each location. We have focused primarily in those clinical and radiographic features that can help us differentiate one pathology from another. We believe that by giving the student a knowledge base through each flowchart, as well as provide clinical cases, will start their curiosity to seek new cases on the Internet or try to look for images that we have not been able to locate due to low frequency. In addition, as this project has been done in English, it will provide the students with necessary tools to do a literature search, as most of the medical and dental literature is in English; thus far, providing the student with this material necessary to make the appropriate searched using keywords in English.
