El uso de microtornillos e implantes en ortodoncia como método para obtener anclaje absoluto está hoy en boga, a pesar de haber transcurrido ya más de cuarenta años desde su descubrimiento. Estos dispositivos han demostrado ser uno de los avances más significativos en la historia moderna de la ortodoncia. Este sistema tiene una singularidad: su uso temporal, el cual, aunque transitorio, aporta ese anclaje absoluto, evitando efectos recíprocos indeseados generados en el transcurso del tratamiento. Las numerosas indicaciones de estos dispositivos ofrecen al ortodoncista un amplio abanico de posibilidades para corregir casos que, hasta hace poco, no se podrían solucionar sin pasar por quirófano y/o llevando aparatología extraoral. La necesidad de colaboración del paciente y la reducción del tiempo de tratamiento, son unas de las principales ventajas. Su eficacia probada, además de su fácil colocación, aportan seguridad y satisfacción en los resultados de los tratamientos, haciendo que cada día sean más populares Objetivo: El propósito de este trabajo es realizar una revisión sistemática de la literatura para cuantificar la capacidad de movimiento sagital de los microtornillos, mostrar que ventajas tienen estos dispositivos frente a los tratamientos convencionales en este plano. The use of miniscrews has become, nowadays, a feasible option to treat several cases that requires absolute anchorage. These devices, have been proven to be one of the most significant developments in the modern history of orthodontics, since its invention, more than forty years ago. They have a distinctive characteristic: its temporary use, which, albeit is transitory, provides that simple absolute anchorage that dentists seek, avoiding the reciprocal effects that are commonly produced over the course of almost every treatment. These devices offer the orthodontist a wide range of possibilities to approach many cases which, until very recently, could only been corrected with major surgery or wearing extraoral appliances. All of the above diminish the necessity of cooperation with the patient, and the overall treatment time decrease too. Its proven efficacy, but also the ease with which it is placed, that doesn’t require any surgery beyond the dentist’s capacity, bring secure results and satisfaction, making them increasingly popular. Aim: The purpose of this systematic review is to quantify the capacity of sagittal movement of the miniscrews, and the advantages that these devices can offer against traditional ways of treatments used in this plane.

Background: This study aims to evaluate alveolar height, buccal, and palatal cortical bone thickness using cone beam computed tomography (CBCT) useful for radiological pre-assessment for various surgical procedures of maxillary anterior region. Materials and Methods: Maxillary central and lateral incisors and canines were bilaterally evaluated in 200 selected patients. Images were obtained with New Tom CBCT and traced with New Net Technologies software. Alveolar height and cortical bone thickness at 3 mm, 6 mm, and 9 mm above the cemetoenamel junction were measured and statistically analyzed. Results: Significant differences in alveolar height were found genderwise and agewise and were found to be highest in age groups of 51–60 years and lowest in 11–20 years. Buccal thickness at 3 mm, 6 mm, 9 mm was highest in right central incisor, right central incisor and left central incisor and lowest in right canine, left canine and left canine, respectively. Palatal thickness at 3 mm, 6 mm, 9 mm was highest in right central incisor, left central incisor and left central incisor and lowest in left canine, left canine, and left canine, respectively. Bucco-palatal thickness at 3 mm, 6 mm, 9 mm was highest in left canine, right central incisor and left central incisor and lowest in right lateral incisor, respectively. Agewise and genderwise significant differences in buccal and palatal bone were found at different levels. Conclusion: Buccal bone is thinner than palatal bone; thus, require careful radiological appraisal in orthodontic tooth movement and any surgical procedure in this region.
