Article Abstract
Background: The design of reverse shoulder arthroplasty (RSA) implants has evolved significantly over the past 50 years. Today there are many options available that differ in design of the glenoid and humeral components, fixation methods, sizes, and modularity. With respect to the humeral component, the literature has generally focused on the differences between inlay and onlay designs and the potential impact on outcomes. However, inlay and onlay design represents only one factor of many.
Methods: It is our hypothesis that separating onlay and inlay designs into 2 distinct entities is an oversimplification as there can be a wide overlap of the 2 designs, depending on surgical technique and the implant selected. As such, the differences between inlay and onlay designs should be measured in absolute terms-meaning combined distalization and lateralization.
Results: By reviewing the many factors that can contribute to the glenosphere-humerus relationship, the role of inlay and onlay humeral designs as an important distinguishing feature is shown to be limited. Preliminary studies suggest that the amount of distalization and lateralization of the construct may be the most accurate method of describing the differences in the constructs.
Conclusions: Inlay and onlay humeral component design represents only one factor of many that may impact outcomes. A more accurate method of defining specific design and technique factors in RSA is the degree of lateralization and distalization.

Benchmarking deep learning-designed inlay restorations across operator experience: An in vitro comparison of time efficiency, contact intensity, and contour quality.
J Dent
September 2025
Department of Reconstructive Dentistry and Gerodontology, School of Dental Medicine, University of Bern, Bern, Switzerland.
Objectives: This in vitro study aimed to evaluate the performance of a deep learning (DL)-based workflow for designing inlays, in terms of time efficiency, contact intensity, and contour quality, by comparing it with human-based workflows. The impact of operator experience was also assessed to examine whether the DL-based workflow could reduce experience-related variability.
Methods: A total of 25 digital scans of maxillary and mandibular arches, including posterior abutments prepared for mesial-occlusal (MO) or distal-occlusal (DO) cavities, were used to design inlays using five different workflows.
Clinical outcomes in patients undergoing reverse shoulder arthroplasty for dislocation arthropathy : a matched case-control study.
Bone Joint J
September 2025
Division of Shoulder and Elbow Surgery, Department of Orthopaedic Surgery, The Johns Hopkins University, Baltimore, Maryland, USA.
Aims: Dislocation arthropathy of the shoulder is an advanced arthritis resulting from recurrent glenohumeral dislocation with or without previous stabilization surgery. The aim of this study was to compare the clinical results of reverse total shoulder arthroplasty (RTSA) in patients with dislocation arthropathy with those with primary osteoarthritis (OA) and glenoid bone loss.
Methods: This was a retrospective matched cohort study including 22 patients with dislocation arthropathy who were treated by one surgeon between 2011 and 2021 and a matched group of 44 patients who were also treated with RTSA, for OA.
Advancements in Inlay Glenoid Components for Anatomic Total Shoulder Arthroplasty: A Review.

While anatomic total shoulder arthroplasty is a successful procedure that provides reliable pain relief and restoration of function in most patients, its success has been limited by glenoid component loosening. While series reporting the outcomes of inlay glenoid components have demonstrated excellent clinical outcomes with low rates of component loosening and need for revision, surgeons have been hesitant to adopt these implants due to concerns of inadequate pain relief secondary to the remaining glenoid rim contacting the humeral head implant. The inset glenoid component, a variant of the traditional inlay components, has gained interest because its design aims to achieve similar stability to traditional inlay components through implantation within strong subchondral bone, reduce the amount of glenoid vault removed compared to inlay components, and has a glenoid face designed to limit the rocking-horse phenomenon.

Comparison of accuracy of three intraoral scanners for different types of tooth preparations: A laboratory study.
Am J Dent
August 2025
Department of Prosthodontics, Gwanak Center, Seoul National University Dental Hospital, Seoul, Korea.
Purpose: To evaluate the laboratory accuracy of three intraoral scanners (IOSs) across three types of tooth preparations, using a laboratory scanner as the reference.
Methods: Models of three types of tooth preparations (inlay, onlay, and three-unit fixed partial denture) were designed with CAD software and fabricated using a 3D printer. Reference data were obtained by scanning these models with a desktop laser scanner (Identica Hybrid, Medit Co).
