Treatment alternatives for the rehabilitation of the posterior edentulous maxilla

Abstract

Rehabilitation of the edentulous maxilla with implant‐supported fixed dental prostheses can represent a significant clinical challenge due to limited bone availability and surgical access, among other factors. This review addresses several treatment options to replace missing teeth in posterior maxillary segments, namely the placement of standard implants in conjunction with maxillary sinus floor augmentation, short implants, tilted implants, and distal cantilever extensions. Pertinent technical information and a concise summary of relevant evidence on the reported outcomes of these different therapeutic approaches are presented, along with a set of clinical guidelines to facilitate decision‐making processes and optimize the outcomes of therapy.

Isolation, identification and osteogenic capability analysis of mesenchymal stem cells derived from different layers of human maxillary sinus membrane

“…Maxillary sinus floor elevation (MSFE) is a classical surgical procedure for bone regeneration in the atrophic maxillary sinus region (Avila‐Ortiz et al, 2023; Farina et al, 2023). At present, the mechanism of osteogenesis in the maxillary sinus region is still being explored to develop therapeutic strategies for efficient autogenous bone regeneration.…”

Additive Manufacturing Titanium Dental Implants Placed in Sinuses Grafted with 70HA:30-TCP: A One-Year Retrospective Study for Evaluation of Survival Rate

“…The management of edentulous areas in the posterior maxilla generally provides limited bone height because of severe post-extraction alveolar crest resorption and age-linked sinus pneumatization [ 1 , 2 ]. These anatomic limitations may affect successful osseointegration and the fabrication of a functional and aesthetic implant-supported prosthesis, dictating the need for reconstructive osseous surgery to re-establish adequate bone volume for implant positioning [ 2 ].…”

“…Currently, grafting the maxillary sinus floor has become a reliable, commonly used surgical procedure to increase bone volume in the posterior maxilla [ 1 , 2 , 3 ], as it allows the placement of dental implants in sites that were previously considered unsuitable for implant insertion because of insufficient bone volume [ 2 ]. Several surgical techniques have been presented to assess the sinus cavity, elevate the sinus membrane, and place bone grafts [ 1 , 2 , 3 ]. In the lateral window sinus lift approach [ 6 ], a window is created through the buccal plate of the maxilla; the sinus membrane is carefully lifted, and autogenous bone (or bone substitute) is placed into the built space.…”
