    Distancia entre los ápices del segundo molar y el piso del seno maxilar mediante tomografías computarizadas enero 2019 - septiembre 2020

    Introduction: The maxillary sinus (MS) is a structure of great interest due to its proximity to the posterior superior dental structures (1). Knowing the distance between these structures is essential when performing pre-surgical planning (2), especially in case of the second molar due to its proximity to the maxillary sinus floor (MSF) (3–7). Objectives: Determine the distance between the apices of the second molar and the maxillary sinus floor using cone beam computed tomography. Methodology: Computed tomography scans were collected from a radiological center in Cuenca (January 2019 - September 2020). Using the Sydexis 4 software version 4.3, the apico-sinus distance was measured in a coronal cut section. The data collection was carried out using a template and the results were analyzed in the IBM SPSS program. Results: The average value of the apico-sinus distance was 0.45mm, 1.36mm and 2.36mm for the mesiobuccal, distobuccal and palatal roots on the right side. On the left side the values were 0.16mm, 0.66mm and 1.12mm respectively. In both cases the mesiobuccal root was the closest to the MSF. Conclusions: The mesiobuccal root of the second molar has the closest relationship with the MSF. Regarding the age group, the shortest distance is observed in group 3 (right side), and group 2 (left side). According to the sex, the average value is similar in the two groups.

    Importancia de la guía anterior en el tratamiento de ortodoncia: Revisión de la literatura
    (2020) Osorio Ayala, Lesly Damaris; Yunga Picon, Maria Yolanda; Pesantez Ibarra, Mateo Jose; Parra Calle, Maria Jose; Paredes Tenesaca, Daniela Germania; Barzallo Sardi, Vinicio Egidio
    Orthodontic treatment must include both functional and aesthetic parameters to establish balance in the stomatognathic system, despite this, in many cases these criterions are not taken into consideration producing alterations at masticatory level. To achieve stability, the treatments must establish an anterior guidance which protects posterior teeth in eccentric movements, thus avoiding, contacts that can have repercussions at teeth’s level, periodontium, temporomandibular joint and oral muscles. This article aims to make known the importance of the anterior guidance in orthodontics and the consequence of avoiding this fundamental parameter of occlusion. The following literature review was carried out by a bibliographic compilation of different studies related to occlusion and function of the anterior guidance, in addition to possible consequences of its absence. It is concluded that without analyzing each factor during the functional movements of the TMJ, will not obtain the desired objectives proposed by the clinical treatment.
