    Se expone una revisión de la literatura científica publicada en revistas indexadas durante el año 2007 sobre Implantología Bucofacial. La escasez de tiempo de que disponen los profesionales para consultar las múltiples fuentes de información, ha motivado a los autores a resumir los artículos publicados y clasificarlos en los siguientes apartados: generalidades, pacientes especiales, superficies y diseños, tejidos blandos, implantes inmediatos, carga inmediata, complicaciones, elevación sinusal, técnicas avanzadas, plasma rico en plaquetas y factores de crecimiento, cirugía guiada, cirugía mínimamente invasiva y miniimplantes, con la intención de facilitar una puesta al día

    Objectives: To determine the efficacy of the pediculate flap with the buccal fat pad in the sealing of orosinusal communications, describe the surgical technique used, and report the main complications. Patients and method: A retrospective study was made of 8 patients seen in the Service of Oral Surgery of the University of Barcelona Dental Clinic (Spain) for the treatment of orosinusal communications between the years 2007 and 2009. In all cases a pediculate flap with the buccal fat pad was used to solve the problem. Results: All of the orosinusal communications were successfully resolved with this technique. The immediate postoperative complications were pain (37.5%), inflammation (37.5%), edema (32.5%), trismus (37.5%), halitosis (14.3%), suppuration (12.5%) and rhinorrhea (12.5%). Conclusions: The use of Bichat"s buccal fat pad is not regarded as the technique of choice for sealing small to medium sized orosinusal communications. However, in the case of large communications, it is a good option, and the results obtained are optimum

    Objectives: A study was made to determine the temperature increment at the dental root surface following Er,Cr:YSGG laser irradiation of the root canal. Design. Human canines and incisors previously instrumented to K file number ISO 30 were used. Irradiation was carried out with glass fiber endodontic tips measuring 200 μm in diameter and especially designed for insertion in the root canal. The teeth were irradiated at 1 and 2 W for 30 seconds, without water spraying or air, and applying a continuous circular movement (approximately 2 mm/sec.) in the apico-coronal direction. Results: At the 1 W power setting, the mean temperature increment was 3.84ºC versus 5.01ºC at 2 W. In all cases the difference in mean value obtained after irradiation versus the mean baseline temperature proved statistically significant (p< 0.05). Conclusions: Application of the Er,Cr:YSGG laser gives rise to a statistically significant temperature increment at the external root surface, though this increment is probably clinically irrelevant, since it would appear to damage the tissues (periodontal ligament and alveolar bone) in proximity to the treated toot

    Objetivos: determinar la eficacia del colgajo pediculado de la bola adiposa de Bichat en el cierre de comunicaciones bucosinusales; describir la técnica quirúrgica utilizada e identificar las principales complicaciones registradas. Pacientes y Método: se realizó un estudio retrospectivo de 8 pacientes que acudieron al Servicio de Cirugía Bucal de la Clínica Odontológica de la Universidad de Barcelona por presentar una comunicación bucosinusal entre los años 2007 y 2009. A todos los pacientes se les efectuó un colgajo pediculado de la bola adiposa de Bichat para solucionar esta complicación. Resultados: las comunicaciones bucosinusales se resolvieron con éxito tras la utilización de esta técnica en todos los casos. Las complicaciones postoperatorias inmediatas observadas fueron dolor (37,5%), inflamación (37,5%), edema (32,5%), trismo (37,5%), halitosis (14,3%), supuración (12,5%), rinorrea (12,5%). Conclusiones : El uso de la bola adiposa de Bichat no suele ser la técnica de elección en el cierre de comunicaciones bucosinusales de tamaños pequeños o medianos, sin embargo, cuando se produce una comunicación bucosinusal de gran tamaño es una buena opción y sus resultados son óptimos

    Complications of guided surgery and immediate loading in oral implantology: a report of 12 cases

    Get PDF
    Objectives: The growing interest in minimally invasive surgery, together with the possibility of fitting prostheses with immediate function, have led to the development of software capable of planning and manufacturing a surgical guide and prosthesis that can be placed upon conclusion of the implant surgery step. The present study evaluates the surgical and prosthetic complications of implant treatment with the guided surgery technique, together with patient comfort during and after treatment. Patients and methods: A retrospective observational study was made of 19 patients with partially or totally edentulous upper and/or lower maxillae, involving the placement of a total of 122 implants. All cases were planned and operated upon with the guided surgery technique. Results: A total of 122 implants were placed in 14 males and 5 females. The intraoperative surgical complications comprised a lack of primary stability, while the postoperative complications consisted of infections and a lack of implant osteointegration. Ten implants failed. The prosthetic complications in turn comprised loosening of the provisional prosthesis screws, prosthesis tooth fracture, and a lack of passive fit of the immediate prosthesis. The degree of patient satisfaction was evaluated using a verbal scale. Conclusions: Implant restoration with the guided surgery technique and immediate functional loading is a predictable procedure, provided patient selection and the surgical technique are adequate, affording lesser postoperative morbidity and increased patient satisfaction thanks to the immediate restoration of esthetics and functio

    Switching TNF antagonists in patients with chronic arthritis: An observational study of 488 patients over a four-year period

    The objective of this work is to analyze the survival of infliximab, etanercept and adalimumab in patients who have switched among tumor necrosis factor (TNF) antagonists for the treatment of chronic arthritis. BIOBADASER is a national registry of patients with different forms of chronic arthritis who are treated with biologics. Using this registry, we have analyzed patient switching of TNF antagonists. The cumulative discontinuation rate was calculated using the actuarial method. The log-rank test was used to compare survival curves, and Cox regression models were used to assess independent factors associated with discontinuing medication. Between February 2000 and September 2004, 4,706 patients were registered in BIOBADASER, of whom 68% had rheumatoid arthritis, 11% ankylosing spondylitis, 10% psoriatic arthritis, and 11% other forms of chronic arthritis. One- and two-year drug survival rates of the TNF antagonist were 0.83 and 0.75, respectively. There were 488 patients treated with more than one TNF antagonist. In this situation, survival of the second TNF antagonist decreased to 0.68 and 0.60 at 1 and 2 years, respectively. Survival was better in patients replacing the first TNF antagonist because of adverse events (hazard ratio (HR) for discontinuation 0.55 (95% confidence interval (CI), 0.34-0.84)), and worse in patients older than 60 years (HR 1.10 (95% CI 0.97-2.49)) or who were treated with infliximab (HR 3.22 (95% CI 2.13-4.87)). In summary, in patients who require continuous therapy and have failed to respond to a TNF antagonist, replacement with a different TNF antagonist may be of use under certain situations. This issue will deserve continuous reassessment with the arrival of new medications. © 2006 Gomez-Reino and Loreto Carmona; licensee BioMed Central Ltd
