          Abstract

          RESUMEN La pérdida ósea marginal periimplantaria (MBL) es un proceso de remodelación no infeccioso que ocurre durante el primer año después de la colocación de un implante dental y todavía en la actualidad, sigue siendo un proceso complejo que sigue suscitando dudas. La asociación entre MBL y enfermedades periimplantarias todavía no está clara del todo, sin embargo, algunos autores así lo han establecido. Por este motivo, el control temprano de la MBL puede ser un factor clave en la prevención de la periimplantitis. Se han descrito factores generales y sistémicos del paciente, factores quirúrgicos asociados a la propia colocación del implante o a los tejidos duros y blandos que lo rodean, pero también a factores prostodónticos y de oclusión. El control de la posición del implante y el volumen de los tejidos, de la estabilidad primaria, de la inflamación postoperatoria y tardía, así como el momento de la carga, el tipo de prótesis o la forma y la altura del pilar, son algunos de los factores identificados como clave actualmente. El objetivo de este trabajo es describir desde un punto de vista reflexivo, la implicación de todos estos factores en el control de la MBL.

          ABSTRACT Peri-implant marginal bone loss (MBL) is a non-infectious remodelling process that occurs during the first year after the placement of a dental implant and even today, it remains a complex process that continues to raise questions. The association between MBL and peri-implant diseases is still not entirely clear, however, some authors have established it. For this reason, early control of MBL may be a key factor in the prevention of peri-implantitis. General and systemic factors of the patient have been described, surgical factors associated with the actual placement of the implant or the surrounding hard and soft tissues, but also prosthodontic and occlusion factors. The control of the position of the implant and the volume of the tissues, of the primary stability, of the postoperative and late inflammation, as well as the moment of the load, the type of prosthesis or the shape and height of the abutment, are some of the factors currently identified as key. The objective of this work is to describe, from a reflexive point of view, the implication of all these factors in the control of MBL.

            Platform switching for marginal bone preservation around dental implants: a systematic review and meta-analysis.

            Platform switching for maintaining peri-implant bone levels has gained popularity among implant manufacturers over the last few years. However, the assumption that the inward shifting of the implant-abutment junction may preserve crestal bone was primarily based on serendipitous finding rather than scientific evidence. The objectives of the present study were to systematically review radiographic marginal bone-level changes and the survival of platform-switched implants compared to conventional platform-matched implants. A literature search of electronic databases (MEDLINE, EMBASE, The Cochrane Oral Health Group's Trials Register, The Cochrane Central Register of Controlled Trials, the U.K. National Research Register, the Australian New Zealand Clinical Trials Registry, the Database of Abstracts of Reviews of Effectiveness, and Conference Proceedings Citation Index) was performed up to March 15, 2010. Hand searches included several dental journals, and authors were contacted for missing information. Controlled trials that compared marginal bone-level changes around platform-switched dental implants with those restored with platform-matched prostheses were selected. The review and meta-analysis were done according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Data were analyzed using two meta-analytic statistical packages. Mean differences (MDs) were calculated for analyzing continuous data, and risk ratios (RRs) were used for dichotomous data with 95% confidence intervals (CIs). Ten studies with 1,239 implants were included. The marginal bone loss around platform-switched implants was significantly less than around platform-matched implants (MD: -0.37; 95% CI: -0.55 to -0.20; P or= 0.4 was associated with a more favorable bone response. The review and meta-analysis show that platform switching may preserve interimplant bone height and soft tissue levels. The degree of marginal bone resorption is inversely related to the extent of the implant-abutment mismatch. Further long-term, well-conducted, randomized controlled studies are needed to confirm the validity of this concept.

              Influence of Vertical Soft Tissue Thickness on Crestal Bone Changes Around Implants with Platform Switching: A Comparative Clinical Study.

              Numerous studies have shown the superiority of platform-switched implants in preserving crestal bone as compared with platform-matched implants. However, the influence of initial soft tissue thickness on development of crestal bone loss has not been addressed in previous studies; thus, further research is needed.
