Immediate Loading in the Maxilla Using Flapless Surgery, Implants Placed in Predetermined Positions, and Prefabricated Provisional Restorations: A Retrospective 3‐Year Clinical Study

Abstract

The study confirmed the feasibility of an immediate-loading treatment protocol in the maxilla, which included flapless surgery, implants and abutments placed in predetermined positions, and prefabricated provisional restorations. All failures occurred within the first 2 months of loading. The unchanged survival rate and the low average bone loss found during the following 34-month study period indicate a good long-term prognosis for the performed immediate-loading treatment.

La carga inmediata con implantes Microdent en el maxilar superior: II. Aspectos prostodóncicos

“…Los diferentes sistemas de conexión entre los implantes y la prótesis mediante los aditamentos protésicos que configuran la interfase implante-pilar han sido también estudiados y han demostrado su éxito en la carga inmediata 3,7,9 . Se ha demostrado que en los implantes con conexión externa las fuerzas oclusales axiales (verticales) y horizontales son transmitidas a la cresta ósea; mientras que en los implantes con conexión interna las fuerzas horizontales son transmitidas a la cresta ósea y las fuerzas verticales son absorbidas a la unión implante/pilar desarrollándose un sistema más fortalecido 21 .…”

“…Se han realizado estudios que demuestran los buenos resultados de la carga inmediata en restauraciones parciales y unitarias en el maxilar superior mediante la inserción de implantes y su restauración provisional inmediata con un éxito acumulativo del 96% después de 1 año de seguimiento o del 91% a los 3 años [8][9] .…”

Immediately loaded full-arch provisional implant restorations using CAD/CAM and guided placement: maxillary and mandibular case reports

“…[3][4][5][6][7] Taking surgical protocols and patient management a step further, there has also been a growing interest in explor ing the potential of a fl apless surgical approach to minimise post-operative trauma and accelerate postoperative healing. [8][9][10] However, this approach can risk significant complications should the operator misinterpret the underlying hard and soft tissue anatomy.…”

Immediate Placement and Provisionalization of Maxillary Posterior Single Implants

“…[26,17] The soft tissue response was very favorable in these studies owing to the presence of a provisional crown throughout the healing phase, which allowed the sculpting of the interdental papilla and the attached gingiva. [26,27,28] In this treatment, an initial insertion torque of at least 45 Ncm was reached. Although clinical studies on immediate single implant loading reported varying minimal insertion torques for immediate loading, the authors of this report adopted a threshold of 45 Ncm.…”
