BackgroundGeometric and spatial relationships are essential for dental practice as a reference. Most manual procedures depend on the operator’s practice and ability, and they are non-assisted and non-controlled, depending on trial and error.AimDescribing the effectiveness of a disruptive innovation aimed at creating unwired technology (clinical surveyor device (CSD)) for assisting an operator’s manual skills/dexterity and controlling applications for training and clinical use in several areas of dentistry: rehabilitation, implants surgery and orthodontics.Materials and methodsTesting the device involved 25 odontology specialists and 20 10th semester undergraduate students and postgraduate residents. A paired Student t-test and Wilcoxon signed-rank test were used for comparison to ascertain whether there was a statistically significant difference when performing procedures with and without using a CSD. Biplot cluster analysis was used for understanding data structure and its variability, capturing variables and individuals’ inter-relationships.ResultA significant difference was found when using a CSD, which rejected the null hypothesis. There was no significant difference (p value of >0.05 regarding operators (experienced maxillofacial, periodontics and rehabilitators, periodoncy and rehabilitation programme final-year residents and 10th semester undergraduate students).ConclusionThe CSD’s advantages regarding accuracy would be related to controlling real hand position, enabling better-assisted operator skills and thereby creating confidence during rehabilitation/implant/orthodontic procedures.

Las empresas comerciales se dedican a la compra y venta de productos terminados, así que, parte del éxito financiero está en el control y la administración del inventario. El análisis de las ventas requiere que se estudie la rotación, identificando aquellos artículos que generan más movimiento y ganancias, esto con la finalidad de implementar planes estratégicos de mejoramiento en la inversión para la consecución de la mercancía. Por otra parte, las compañías que cuentan con varios sitios de venta requieren de un control sobre sus tiendas en términos de gestionar los inventarios. La operación crece y se vuelve compleja ya que comprende diferentes clases de productos y diferentes sedes de venta, se genera mucha información que necesita ser analizada. La estadística provee diferentes técnicas para el análisis de este tipo de datos, las cuales se utilizaron para agrupar y clasificar tanto artículos como puntos de venta, analizando la evolución de las series de las cantidades vendidas mediante los modelos SARIMA de series temporales.
