          Abstract

          RESUMEN El uso de pilares de cicatrización transmucosos previos a la colocación del,pilar protésico definitivo es una técnica que se ha desarrollado durante muchos años en la implantología clásica. La desconexión y conexión de forma repetida de estos pilares o aditamentos dan lugar a una respuesta ósea negativa que se manifiesta en forma de pérdida de hueso a nivel de la cresta marginal, acompañada por una migración apical de tejidos blandos. Este artículo pretende realizar una revisión de la literatura del estado actual del uso de los pilares transmucosos definitivos con colocación inmediata el día de la inserción de los implantes y el mantenimiento del sellado biológico, minimizando la pérdida ósea periimplantaria y remodelando de forma adecuada los tejidos blandos adyacentes, frente al protocolo tradiciónal del uso de aditamentos que se desconectan en multiples ocasiones produciendo pérdida ósea periimplantaria. La evidencia científica sugiere que los mejores resultados biológicos, estéticos y funciónales se consiguen con el uso del pilar definitivo colocado de forma inmediata a la inserción del implante, especialmente en implantes colocados de forma yuxtacrestal y en implantes postextracción.

          ABSTRACT The use of transmucosal healing abutments before the placement of the definitive prosthetic abutment is a technique that has been developed for many years in classical implantology. Repeated disconnection and connection of theses abutments result in a negative bone response that manifests as bone loss at the marginal ridge level, accompanied by apical soft tissue migration. This article aims to review the current status in the scientific literature of the use of the definitive transepithelial abutments with immediate placement on the day of implant insertion and maintenance of the biological seal, minimizing peri-implant bone loss and adequately remodeling the adjacent soft tissues, compared to the traditional protocol of the use of abutments that are disconnected on multiple occasions producing peri-implant bone loss. Scientific evidence suggests that the best biological, aesthetic, and functional results are achieved with the use of the definitive abutment placed immediately after implant insertion, especially in yuxtacrestal implants and post-extraction implants.

          The mucosal barrier following abutment dis/reconnection. An experimental study in dogs.

          In the present experiment, the effect on the marginal peri-implant tissues following repeated abutment removal and subsequent reconnection was studied. 5 beagle dogs were used. The mandibular premolars were extracted and 2 fixtures of the Brånemark System were installed, 1 in each mandibular quadrant. 3 months later, abutment connection was performed. A 6-month period of plaque control was initiated. Once a month during the plaque control period, the abutment of the right side (test) in each dog was disconnected, cleaned and reconnected to the failure. Thus, each test abutment was removed and reconnected altogether 5x during this period. The contralateral abutment remained undisturbed for 6 months and served as control. 1 month after the last reconnection, the animals were sacrificed and tissue samples, comprising the implant and the surrounding soft and hard peri-implant tissues, were obtained, decalcified, embedded in Epon and sectioned. The following landmarks were identified and used for linear measurements: PM (the marginal portion of the peri-implant mucosa), aJE (the level of the apical termination of the junctional epithelium), B (the marginal level of bone to implant contact), A/F (the abutment/fixture border). The findings indicate that the dis- and subsequent reconnections of the abutment component of the implant compromised the mucosal barrier and resulted in a more "apically" positioned zone of connective tissue. The additional marginal bone resorption observed at the test sites following abutment manipulation may be the result of tissue reactions initiated to establish a proper "biological width" of the mucosal-implant barrier.

              Soft tissue reactions to non-submerged unloaded titanium implants in beagle dogs.

              The soft tissue reactions to non-submerged unloaded titanium implants were examined. A total of 24 implants were placed in 6 beagle dogs. The implants differed in their crestal area by having either a rough sandblasted, a fine sandblasted, or a polished surface. After 3 months, all implants were firmly anchored in the bone and had no clinical signs of peri-implant inflammation. Undecalcified histologic sections demonstrated that all implants achieved osseointegration with direct bone contact. The epithelial structures showed a peri-implant sulcus with a non-keratinized sulcular epithelium and a junctional epithelium. None of the sections exhibited epithelial downgrowth to the alveolar crest. In the supracrestal area, a direct connective tissue contact to the implant post was observed. An approximately 50 to 100 microns wide zone of dense circular fibers was found close to the implant surface. It was free of blood vessels and resembled closely an inflammation-free scar tissue formation. This zone was surrounded by a looser connective tissue with a 3-dimensional network of collagen fibers running in different directions. No significant differences concerning soft tissue reactions were found between the 3 implant surfaces. In particular, the length of direct connective tissue contact was similar. Concerning bone reactions, a significantly shorter distance from the top of the implant to the most coronal bone-implant contact was observed for rough surfaces. It is concluded that non-submerged unloaded titanium implants achieved a complication-free tissue integration with a dense connective tissue in direct contact to the implant surface in the supracrestal area, and epithelial structures similar to those around natural teeth. The different surface textures did not influence the healing pattern of the soft tissues, but had an influence on the location of the most coronal bone-implant contact.
