Statement Of Problem: Patients needing dental rehabilitation of a complete atrophic maxilla would benefit from simplified treatment plans.
Purpose: The purpose of this case series was to demonstrate the prosthetic management of 4 edentulous patients with severe maxillary ridge resorption who declined multiple stage surgery and sought a fixed prosthesis in single-stage surgery.
Material And Methods: The patients were provided with completely digital computer-aided designed and computer-aided manufactured (CAD-CAM) polyetheretherketone (PEEK) maxillary subperiosteal frameworks, which were surgically placed in a 1-step procedure. The patients were followed up for 12 months and evaluated for signs of implant rejection, infection, prosthetic fracture or mobility, or implant exposure.
Results: At the 12-month follow-up, all the implants were functionally stable with healthy soft tissue and showed no sign of prosthetic fracture, infection, or pus discharge.
Conclusions: PEEK subperiosteal implants for maxillary atrophied ridges can be considered a promising treatment option within the limitations of this clinical study with low patient numbers and a short observational time.

Background: Worn dentition is a common problem encountered by most people in the last decade. Rehabilitation of a full mouth needs individual attention and proper treatment planning, which is very challenging for partial edentulous cases where bilateral teeth are missing and collapsed vertical dimension leaves inadequate restorative space. Treatment of these cases is complex and needs to apply standard principles while designing and fabricating prostheses.

Background: This study evaluates the efficacy of carbon fiber reinforced Polyetheretherketone (Cfr-PEEK) in fixation after sagittal split ramus osteotomy (SSRO) by comparing it with titanium in vitro.
Methods: Twenty-eight sheep hemimandibles were randomly assigned to four groups for SSRO surgery. Fixation was performed with a 4-hole titanium mini plate for 5 mm advancement in Group 1, with a 4-hole Cfr-PEEK mini plate for 5 mm advancement for Group 2, with a 4-hole titanium mini plate for 10 mm advancement for Group 3, and with a 4-hole Cfr-PEEK mini plate for 10 mm advancement for Group 4.

Division of Restorative Dentistry, Periodontology and Prosthodontics, Department of Dental Medicine and Oral Health, Medical University of Graz, Billrothgasse 4, Graz, 8010, Austria.
Aims: Bone preservation is a requirement for long-term stability of dental prostheses, which is all the more important in the posterior mandible, given the particular challenges these areas pose to prosthetic treatment. The objective was to investigate the implications of different prostheses on the atrophy of posterior alveolar bone after tooth loss.
Materials And Methods: A total of 457 treatment cases were retrieved from the medical documentation and information network.

Department of Restorative Dentistry, Recep Tayyip Erdoğan University, Rize, Turkey.
Objectives: The aim of this systematic review and network meta-analysis was to compare the flexural strength of provisional fixed dental prostheses (PFDPs) fabricated using different 3D printing technologies, including digital light processing (DLP), stereolithography (SLA), liquid crystal display (LCD), selective laser sintering (SLS), Digital Light Synthesis (DLS), and fused deposition modeling (FDM).
Materials And Methods: A comprehensive literature search was conducted in databases including PubMed, Web of Science, Scopus, and Open Grey up to September 2024. Studies evaluating the flexural strength of PFDPs fabricated by 3D printing systems were included.
Background: The purpose of this study was to assess impingement-free internal rotation (IR) in a virtual reverse shoulder arthroplasty simulation using a Statistical Shape Model based on scapula size.
Methods: A database of over 10,000 scapulae utilized for preoperative planning for shoulder arthroplasty was analyzed with a Statistical Shape Model to obtain 5 scapula sizes including the mean and 2 standard deviations. For each scapula model, one glenosphere size (33-42 mm) was selected as the best fit based on consensus among 3 shoulder surgeons.
