          Abstract

          RESUMEN Introducción: El posicionamiento de implantes dentales simultáneos a la elevación de seno maxilar en rebordes con reabsorción severa < 4mm es una técnica quirúrgica sensible que disminuye los tiempos operatorios. Sin embargo, es considerada cirujano-dependiente y en caso de no darse el manejo adecuado puede generar complicaciones. Objetivo: Evaluar, luego de 24 meses de carga funcional, la estabilidad de los tejidos periimplantares del implante dental que se posicionó simultáneo a la elevación de seno maxilar en un reborde alveolar con reabsorción ósea severa < 4mm. Presentación de caso: Paciente masculino de 62 años con reabsorción ósea severa en zona de primer molar superior derecho. Luego de analizar los medios diagnósticos y la evidencia científica; se logró posicionar un implante dental simultáneo a la elevación de seno maxilar técnica de ventana lateral; cuatro meses después se realizó la segunda fase quirúrgica y finalmente fue rehabilitado con una corona en zirconio. Tuvo un periodo de seguimiento de 24 meses. Conclusiones: Un buen diagnóstico, manejo quirúrgico adecuado, la colaboración del paciente y los controles periódicos, resultan en una técnica segura, que proporciona estabilidad de los tejidos periimplantares.

          ABSTRACT Introduction: Dental implant placement simultaneous with maxillary sinus lifting on ridges with severe resorption < 4 mm is a sensitive surgical technique that shortens the duration of interventions. However, it is considered to be operator dependent, and may cause complications if not appropriately managed. Objective: After 24 months of functional load, evaluate the stability of the peri-implant tissue of a dental implant placed simultaneously with maxillary sinus lifting on an alveolar ridge with severe bone resorption. Case presentation: A case is presented of a male 62-year-old patient with severe bone resorption in the area of the first upper right molar. Analysis of the diagnostic means and scientific evidence involved led to placement of a dental implant simultaneous with maxillary sinus lifting (lateral window technique). The second surgical stage was performed four months later. A zirconium crown was finally placed, and a 24-month follow-up period was started. Conclusions: With a good diagnosis, appropriate surgical management, patient cooperation and periodic controls, it is a safe technique that ensures the stability of peri-implant tissue.

            Maxillary and sinus implant reconstructions.

            H. Tatum (1986)
            The root and sinus series of the Omnii system have been used extensively since 1981. They are very versatile in their ability to be used within edentulous areas of the maxilla. Their design attempts to maximize the use of the available bone, and placement techniques allow the manipulation of bone to form sockets in otherwise deficient areas of bone. The root implants can be used as free-standing implants or as multiple abutments. The sinus implant is always used as an abutment. It may be used in conjunction with other implants or with natural abutments. Maxillary implants are not loaded until a 6-month healing time has elapsed following placement. An understanding of the different qualities of bone found in the maxilla is important to achieving the successful loading of these implants. Different times are required to allow physiologic loading in different qualities of maxillary bone. Restorative treatment is normally done with fixed bridge work, and the use of any type of stress breaker attachments is not recommended.

              A new concept in maxillary implant surgery: the osteotome technique.

              This article reviews the limitations of drilling into soft bone to place endosseous implants. Differences among bone types and the anatomy of the maxilla are described. The osteotome technique, which is a new method of placing implants into maxillary bone without drilling, and the rationale for two other procedures, the osteotome sinus floor elevation and the ridge expansion osteotomy, are detailed. How osteotomes conserve osseous tissue and may improve bone density around the implant is also discussed. A pilot study that shows excellent results with several types of press-fit implants using the osteotome technique is provided. The author concludes that the osteotome technique is superior to drilling for many applications in soft maxillary bone. Furthermore, the osteotome technique allows more implants to be inserted in a greater variety of sites during a routine office procedure.
