Resumen
Los terceros molares son las últimas piezas que erupcionan en los arcos dentales y se retienen con mayor frecuencia, por lo que resultan en una exodoncia quirúrgica que se realiza comúnmente en la práctica dental. Las principales causas de retención dental son embriológicas, malformaciones, mecánicas, filogenéticas y las asociadas a enfermedades genéticas. Existen varias clasificaciones según la posición del eje longitudinal del diente, según la profundidad, entre otras. Las complicaciones más comunes del procedimiento de extracción quirúrgica convencional están relacionadas con la osteotomía extensa y la visualización deficiente del sitio quirúrgico, lo que puede generar consecuencias posquirúrgicas como inflamación, dolor, trismo, lesiones reversibles e irreversibles Neuropraxia, Axonotmesis, Neurotmesis de la nervio alveolar inferior (NAI) o nervio lingual, riesgo de fractura y formación de defectos periodontales del segundo molar. El objetivo de la investigación es determinar la eficacia de la exodoncia quirúrgica del tercer molar en la posición mesioangular de acuerdo con la clasificación Pell Gregory Clase I-A. Metodología: presentación de un caso clínico del tercer molar número 48 semiretenido con sintomatología, en un paciente masculino de 27 años. En el caso de las retenciones, es necesaria una evaluación exhaustiva del paciente para garantizar el equilibrio funcional y estético. Una exodoncia de un tercer molar en posición mesioangular I-A según Pell y Gregory se realizó en un paciente que asistió a la clínica de cirugía de la facultad de odontología de la Universidad de Guayaquil. Mediante este procedimiento, se puede adquirir experiencia y pericia en el manejo clínico quirúrgico durante el período quirúrgico y postoperatorio
Third molars are the last pieces to erupt in the dental arches and are most often retained, thus they result in surgical exodontia that is commonly performed in dental practice. The main causes of dental retention are embryological, malformations, mechanical, phylogenetic and those associated with genetic diseases. There are several classifications according to the position of the longitudinal axis of the tooth, to the depth, among others. The most common complications of the conventional surgical extraction procedure are related to the extensive osteotomy and poor visualization of the surgical site, which can generate post-surgical consequences such as inflammation, pain, trismus, reversible and irreversible lesions Neuropraxia, Axonotmesis, Neurotmesis of the inferior alveolar nerve (NAI) or lingual nerve, risk of fracture and formation of periodontal defects of the second molar. The research’s aim is to determine the efficacy of the third molar surgical exodontia in the mesioangular position according to the Pell Gregory Class 1-A classification. Methodology: presentation of a clinical case of the third molar number 48 semidetained with symptomatology, in a 27-year-old male patient. In the case of retentions, a comprehensive assessment of the patient is necessary to ensure functional and aesthetic balance. An exodontia of a third molar in mesioangular position I-A according to Pell and Gregory was performed in a patient who attended the surgery clinic of the dentistry faculty at the University of Guayaquil. Through this procedure experience and expertise in clinical surgical management can be acquired during the operative and postoperative period.
