“…This radiolucency had reabsorbed the thin cortical resulting in a buco-sinusal communication. A deep root protrusion into the maxillary sinus (type 3) 20 was also observed. The tooth extraction was carefully performed trying to preserve the scarce remaining bone.…”

Severe atrophic posterior maxillary ridge (residual bone height < 3 mm) could be a challenging situation to place dental implants. Several treatment options have been proposed, but some of them may require advanced surgical skills to achieve best results. In this article, we present a novel and easier technique to allow implant placing in localized areas of severe atrophy. In a first step, a 4.5-length extra-short (unloaded) implant is placed after a transcrestal maxillary sinus floor augmentation (MSFA). After the gained apical bone consolidation, this “temporary implant” is atraumatically removed and a longer and wider definitive implant is placed to support the definitive single restoration. The case of a 45-year-old female treated with this approach is also presented. The patient suffered a severe resorption in the upper right molar area after a tooth extraction. Four months after the “temporary implant” placement and MSFA grafting with plasma rich in growth factors and autologous bone, 3 mm of dense apical bone gain could be observed. In a second surgical time, the 4.5 mm-length “temporary implant” was removed, and a 5.5 mm-length “definitive implant” was placed. This second implant was placed in a denser type 1 (1,000 Hounsfield Unit) new formed apical bone. Four months later, the implant was loaded with a screw-retained crown over a transepithelial (intermediate abutment). After 1-year follow-up, the implant was in health and no mechanical or biological complications were noticed. The satisfactory results of this case encourage the realization of new studies to elucidate its reproducibility.

La anatomía del seno maxilar (SM) tiene una estrecha relación con las raíces dentales superiores, convirtiéndose en un reto para tratamientos endodónticos. El piso del seno maxilar esta recubierto por una fina capa cortical y por la membrana de Schneider, la cual puede llegar a ser perforada causando una comunicación endoantral. Las comunicaciones pueden ser visibles mediante el empleo de una Tomografía Computarizada de Haz Cónico (TCHC) que no permite visualizar diferentes planos para identificar la extensión de una lesión periapical o una iatrogenia. Por ello el objetivo de este estudio es establecer la proximidad entre las raíces dentarias del maxilar superior con respecto al seno maxilar (SM) con información de estudios ejecutados, empleando TCHC y su importancia en la rama de la endodoncia, en bases de datos como Pubmed, Google Scholar y ELSIERVER desde el año 2012 a 2022. Utilizando las siguientes palabras clave: Tomografía Computarizada de Haz Cónico, Endodoncia, Seno Maxilar, Raíz del Diente, Proximidad. Obteniendo 669 artículos científicos, los cuales 30 artículos cumplieron los criterios de inclusión y exclusión. Demostrando que la raíz mesiovestibular del segundo molar superior se encontró con mayor frecuencia dentro del piso del seno maxilar en la mayoría evaluaciones tomográficas. Concluyendo que para el estudio completo de la anatomía del PSM y su íntima relación con las raíces dentarias es importante implementar TCHC, que brinde información completa y tridimensional sobre la anatomía del PSM, ya que este puede extenderse hacia regiones anteriores, siendo más probable el riesgo de causar una comunicación endoantral.

“…Accuracy check is possible with parameters such as deviation at the entry point, deviation at the apex, angle deviation or deviation of the long axis, and deviation in height/depth [6]. On an average, < 0.5 mm errors were reported from computed tomography or conebeam computed tomography imaging acquisition and data processing [77,78].…”

One of the most key areas of dentistry is dental implant surgery. The use of digital equipment and software in dentistry has developed considerably in recent years compared to other fields of medicine. Since examining the advantages and disadvantages of each approach, along with case studies, can help physicians make informed decisions, this review study aims to raise the awareness of dentists to make easier decisions about using guided or free-hand surgery. When planning for a dental implant, one of the most challenging questions that doctors face is which method to use (guided surgery or free-hand). Choosing the right method, such as other clinical considerations, will depend on the individual circumstances of each patient and the preference of the treating physician. Free-hand surgery is a cost-effective method in which the flap is reflected, and, according to the doctor's diagnostic information, an implant is placed, which in many cases is a useful method. Guided surgery has the highest level of accuracy and control, in which osteotomy is designed and printed through a digital surgery guide, and depending on the complexity of the case and the patient's anatomy, it has a higher level of value than free surgery. The surgical guide helps the surgeon make the implant surgery more accurate, safer, simpler, at a lower cost, and in less time. In fact, there are patterns that convey information about the position of the tooth to the dentist before the implant is placed.
