          RESUMEN Introducción: El objetivo del presente estudio era mostrar los resultados clínicos del tratamiento del maxilar superior posterior con implantes colocados mediante la técnica de elevación transalveolar del seno maxilar en pacientes geriátricos. Pacientes y Métodos: 24 pacientes geriátricos (15 hombres y 9 mujeres) con pérdidas dentales maxilares fueron tratados con 28 implantes diferentes colocados mediante la técnica de elevación sinusal transalveolar para su posterior rehabilitación prostodóncica. Los implantes fueron cargados después de un periodo de cicatrización de 6 meses. Resultados: Los hallazgos clínicos indican una supervivencia y éxito de los implantes del 96,4%. En un paciente de los 24 tratados (4,2%) se perdió un implante (3,6%). La altura ósea residual media fué de 6,38 ±1,10 mm (rango:5-10 mm). La ganancia media de hueso vertical fué de 4,40 ±1,15 mm (rango: 2-7 mm). 67,8% de los implantes se insertaron en localización molar y el 32,2% en la localización premolar. Se utilizaron biomateriales en el 97,8% de los implantes. Se realizaron coronas unitarias en 20 pacientes (83,3%), puentes fijos en 3 pacientes (12,5%) y una sobredentadura con bolas en un paciente (4,2%). El seguimiento medio de los pacientes estudiados ha sido de 64,2 ±8,6 meses con un rango entre 50 y 82 meses. Conclusiones: Este estudio indica que el tratamiento con implantes dentales mediante la elevación transalveolar del seno maxilar superior en pacientes geriátricos, constituye una terapéutica implantológica con una elevada tasa de éxito.

          ABSTRACT Introduction: The aim of this study was to report the clinical findings of treatment of posterior maxilla with dental implants inserted by transalveolar sinus elevation in geriatric patients. Patients and Methods: 24 geriatric patients (15 males and 9 females) with maxillary tooth loss were treated with 28 different implants placed by transalveolar sinus elevation for rehabilitation of posterior maxilla. Implants were loaded after a healing free-loading period of 6 months. Results: Clinical findings indicate a survival and success rate of implants of 96.4%. In one patient of 24 treated patients (4.2%), one implant was lost (3.6%). The mean residual height was 6.38 mm±1.10 mm (range: 5-10 mm). The mean elevation height was 4.40 mm±1.10 mm (range: 2-7 mm). 67.8% of implants were inserted in molar and 32.2% in premolar localization. Bone substitutes were used in 97.8% of implants. Twenty patients (83.3%) were restored with single crowns, 3 patients with fixed bridges (12.5%) and one patient (4.2%) with overdenture. The mean follow-up period of treated patients was 64.2 ±8.6 months (range: 50-82 months). Conclusions: This study indicates that treatment with dental implants placed by transalveolar sinus elevation in geriatric patients constitute an implant treatment with a high success rate.

          A systematic review of the success of sinus floor elevation and survival of implants inserted in combination with sinus floor elevation. Part II: transalveolar technique.

          The objectives of this systematic review were to assess the survival rate of implants placed in sites with transalveolar sinus floor elevation. An electronic search was conducted to identify prospective and retrospective cohort studies on transalveolar sinus floor elevation, with a mean follow-up time of at least 1 year after functional loading. Failure and complication rates were analyzed using random-effects Poisson regression models to obtain summary estimates/ year proportions. The search provided 849 titles. Full-text analysis was performed for 176 articles, resulting in 19 studies that met the inclusion criteria. Meta-analysis of these studies indicated an estimated annual failure rate of 2.48% (95% confidence interval (95% CI): 1.37-4.49%) translating to an estimated survival rate of 92.8% (95% CI): 87.4-96.0%) for implants placed in transalveolarly augmented sinuses, after 3 years in function. Furthermore, subject-based analysis revealed an estimated annual failure of 3.71% (95% CI: 1.21-11.38%), translating to 10.5% (95% CI: 3.6-28.9%) of the subjects experiencing implant loss over 3 years. Survival rates of implants placed in transalveolar sinus floor augmentation sites are comparable to those in non-augmented sites. This technique is predictable with a low incidence of complications during and post-operatively.

            Recent Trends in Sinus Lift Surgery and Their Clinical Implications.

            Sinus lift procedures are used to allow residual bone to accommodate functional implants in atrophic posterior maxilla. Numerous anatomical and surgical advancements in sinus lift surgery are still inspiring clinicians.

              Minimally invasive sinus lift implant device: a multicenter safety and efficacy trial preliminary results.

              In cases of advanced maxillary sinus atrophy of the bone (pneumatization), the sinus floor has to be augmented in order to obtain acceptable bone volume for implantation. The objective of the present study is to evaluate a new procedure and device, designed as a closed sinus lift using a dedicated dental implant that allows for Schneiderian membrane elevation and the placement of a flowable bone replacement graft.
