Background: Intraoral scanners (IOS) offer advantages in implant dentistry, but accuracy depends on factors including implant scan body (ISB) material and implant angulation. Conflicting evidence exists on the performance of Titanium (Ti) versus PEEK ISBs, especially with angulated implants. This study aimed to evaluate the combined effect of ISB material (PEEK vs.

Adjacent segment disease (ASD) is a common complication and cause of reoperation following lumbar spinal fusion. Although most commonly performed with titanium or other metal rods, the use of polyetheretherketone (PEEK) rods in spinal fusion has increased. It has been hypothesized that the material properties of PEEK, compared to titanium, allow for less strain on, and therefore less degeneration of, segments adjacent to the fused segments.

Statement Of Problem: The performance of cobalt chromium (Co-Cr) removable partial dentures (RPDs) is well established, but a comparison with the polyetheretherketone (PEEK) in terms of fit, retention, clinical performance, patient outcomes, and associated complications is lacking.
Purpos: The purpose of this systematic review was to evaluate the current evidence on the performance of PEEK as a framework or clasp material compared with Co-Cr for the fabrication of RPDs.
Material And Methods: An electronic search for articles in the English language through PubMed, Scopus, and Web of Science databases from 2000 to 2024 and screened by 2 independent reviewers was made to identify in vitro or clinical studies comparing PEEK with Co-Cr for the fabrication of RPD frameworks and clasps.

Study Design: Retrospective cohort study.
Objective: To assess potential risk factors for cage subsidence after transforaminal lumbar interbody fusion (TLIF), specifically comparing polyetheretherketone (PEEK) versus titanium cages.
Summary Of Background Data: PEEK and titanium cages are commonly used for arthrodesis in TLIF.

Objective: The purpose of this study was to identify risk factors for mechanical complications following complex spinal reconstruction for spondylectomy of primary spinal column tumors.
Methods: A retrospective chart review identified patients treated with spondylectomy for primary spinal column tumors in the thoracic or lumbar spine followed by posterior instrumentation and anterior column reconstruction. Variables collected included basic demographics, smoking status, chronic steroid use, frailty (Charlson Comorbidity Index), extent of resection, Weinstein-Boriani-Biagini classification, tumor volume, Spine Instability Neoplastic Score, anterior column reconstruction and fixation techniques, rod characteristics, Hounsfield units (HUs), and neoadjuvant/adjuvant chemoradiation.
