          Abstract

          RESUMEN Introducción: El objetivo del presente estudio era mostrar los resultados de la pérdida ósea marginal en el tratamiento con rehabilitación fija mediante implantes dentales en pacientes edéntulos totales. Material y Métodos: 24 pacientes edéntulos fueron tratados con 210 implantes KTX ® con superficie arenada y grabada para la rehabilitación total fija. Los implantes fueron cargados inmediatamente en el mismo día de la cirugía. El seguimiento clínico medio fue de 37,1 ±14,6 meses. Resultados: Los hallazgos clínicos indican una supervivencia y éxito de los implantes del 99,5%. Los pacientes fueron rehabilitados con 33 prótesis totales fijas atornilladas. Complicaciones biológicas fueron observadas en el 50% de los pacientes y las complicaciones prostodóncicas en el 4,2% de los pacientes. La pérdida ósea marginal fue de 1,33± 0,77 mm. La pérdida ósea marginal no estuvo relacionada significativamente con la edad, sexo, hábito de fumar, antecedentes médicos, tipos de prótesis y seguimiento clínico. Conclusiones: Este estudio indica que la rehabilitación fija mediante implantes dentales en pacientes edéntulos totales constituye una terapéutica con éxito con una pérdida ósea marginal frecuente.

          ABSTRACT Introduction: The aim of this study was to report the outcome of marginal bone loss in the treatment of fully edentulous patients with fixed prostheses supported with dental implants. Material & Methods: 24 edentulous patients were treated with 210 KTX ® sandblasted and acid surface implants for fixed maxilla/mandible rehabilitation. Implants were immediately loaded in the same day of the surgery. The mean follow-up was 37.1 ±14.6 months. Results: Clinical results indicate a survival and success rate of implants of 99.5%. One implant was lost during the follow-up period. The patients were restored with 33 screw fixed rehabilitations. Biological complications were observed in 50% of patients and technical complications in 4.2% of patients. Mean marginal bone loss was 1.33 ± 0. 77 mm. Marginal bone loss are not significantly related with age, gender, smoking, medical background, types of prostheses, and clinical follow-up. Conclusions: This study indicates that fixed rehabilitations by dental implants in totally edentulous patients constitute a successful treatment with a frequent marginal bone loss.

          Marginal bone loss as success criterion in implant dentistry: beyond 2 mm

          The aim of this study was to analyze marginal bone loss (MBL) rates around implants to establish the difference between physiological bone loss and bone loss due to peri-implantitis.

              Reasons for marginal bone loss around oral implants.

              The reasons for long-term marginal bone loss around oral implants are not well understood. The aim of this paper is to analyze presented evidence behind anticipated reasons for long-term marginal bone loss around oral implants. A computerized research was conducted on PubMed in April 2011 with the following keywords: oral implants and marginal bone resorption/crestal bone loss/bone loss/bone resorption. This search resulted in a total of one thousand one hundred ninety-four papers of which seven hundred fifty-three were clinical contributions. Further search and filtering finally resulted in 21 experimental studies and one hundred sixteen clinical studies, which were reviewed. No evidence was found that primary infection caused marginal bone resorption. Clinical papers that have reported high levels of peri-implantitis were not supported by data given. Clinical evidence was presented that the so-called combined factors (implant hardware, clinical handling, and patient characteristics) may lead to marginal bone resorption. However, once tissue damage has been caused by combined factors, inflammation and/or infection may develop secondarily and then result in peri-implantitis that may need particular clinical treatment. As marginal bone loss primarily depends on numerous background factors, it seems logical that, for example, the use of poorly constructed implants placed and handled by untrained clinicians may result in high numbers of patients with secondary problems in form of peri-implantitis; having said this, control of combined factors may likewise lead to very good clinical results where peri-implantitis would represent a very rare disease indeed even at follow-up times of 10 years or more. © 2012 Wiley Periodicals, Inc.
