Successful implementation of an osseointegration program requires a skilled and committed interdisciplinary team engaged in supporting patients and their families throughout the OI process. The roles and responsibilities of clinical and ancillary team members are described in detail, along with a discussion of the needed patient and family support resources. Time spent developing the interdisciplinary team, with strong regulatory support and engagement of hospital administration and the health system, will promote higher patient satisfaction and outcomes and innovative future directions.

Basic science research is vital for advancing the emerging field of bone-anchored limb replacement (BALR), or osseointegration (OI). This article discusses clinical challenges for BALR/OI, summarizes current basic science research regarding those challenges, identifies research gaps, and proposes future directions. OI research draws from related fields such as orthopaedic implants and dentistry.

Purpose: This study aims to investigate the stress distribution in bone tissue, implant, abutment, screw, and bridge restoration when the mesial implant is placed axially and the distal implant is inserted at varying angles in the posterior maxillary region with free-end partial dentition defects, using three-dimensional finite element analysis.
Materials And Methods: Cone-beam computed-tomography were utilized to create 3D reconstruction models of the maxilla. Stereolithography data of dental implants and accessories were used to design a three-unit full zirconia bridge for the maxillary model.

Orthopedic hip implant failure due to adverse events, such as infection, are still a major problem leading to high morbidity and mortality. Over the years, various innovative biomaterials have been investigated to improve safety and functionality of implants. Although novel biomaterials show initial promising results, many fail at the (later) stages of safety testing.

Background: Osseointegrated prostheses (OIP) use is increasing for above-knee amputees who have difficulties with sockets. This study aims to simulate the bone-implant interface under loading using a 3D finite element (FE) model and quantify force distribution to produce hypotheses on bone remodelling and implant failure, informing implant and surgical design, and rehabilitation protocols.
Methods: Ten customised 3D femur FE models (5 female, 5 male) were generated from CT scans and bone-implant assemblies created.
