Carga inmediata sobre implante único: estudio clínico prospectivo

introduction: immediate loading of implants has become a viable treatment alternative that offers multiple benefits for patients such as providing immediate function and esthetics, reduction of surgical trauma and less treatment time. a controlled prospective clinical trial was conducted to evaluate the success of immediately loaded implants for single-tooth restoration following consensus protocols in recent literature. methods: twenty-one 3.75 x 13mm rbm-treated surface internal connection implants (renova？, lifecore biomedical inc., chaska mn. ) were placed in 17 systemically healthy patients (6 males, 11 females), ages between 18 and 74 years who required single-tooth replacement in the anterior and premolar regions of both jaws. results: the 18-month cumulative success rate for this study was 95.2%. according to the statistical analysis in this study, immediate loading of implants for single-tooth restoration compares favorably to the two-stage protocol and a direct correlation between the distance from bone to contact point and papilla filling was found. conclusions: results from the present study indicate that the single-tooth restoration in the anterior area with immediately loaded surface-treated threaded titanium implants and no occlusal function is a viable treatment alternative with a success rate greater than 95%, comparable to the conventional loading protocol.
