Purpose: The objective of this retrospective clinical study was to evaluate the short-term performance of implants and implant-supported dental restorations (single crowns, fixed/removable dental prostheses, and overdentures) and to identify risk factors for prosthetic complications under the conditions of general dental practice.
Materials And Methods: De-identified data extracted from electronic patient records were analyzed to clarify the research question. Patient-related variables and implant- and suprastructure-related variables were documented for each patient. The probability of complication-free survival after 1 and 2 years was evaluated using the Kaplan-Meier method. In addition, the prosthetic complications were analyzed using Cox regression models.
Results: Eighty-four patients with 134 healed dental implants supporting 107 restorations were studied over a clinical period of up to 52 months (mean: 23.9 months). Of the implants placed, nine (4.8%) failed during the healing phase. Of the healed implants, peri-implant bone loss occurred for two implants among two patients. Nonetheless, these two implants remained functional. Complications were as follows: peri-implantitis (1.5%), loss of retention (10%), loosening of the abutment screw (6%), and chipping of the veneer material (3.7%). The probability of complication-free survival for suprastructures alone was 92% (95% CI: 86% to 96%) after 1 year and 84% (95% CI: 75% to 90%) after 2 years of clinical service. Taking into consideration all complications/failures of implants and of restorations, complication-free survival was 86% (80% to 91%) and 79% (70% to 85%) after 1 and 2 years, respectively.
Conclusion: Both healed dental implants and implant-supported restorations placed in general practice have a high incidence of success; the survival rates seen during the quite short observation period appear comparable to institutional study outcomes. However, technical prosthetic complications are not uncommon among general practice restorations and probably occur more often than in university studies.

Objective: This expert opinion presents provisional guidelines for addressing complications associated with Additively Manufactured Subperiosteal Jaw Implants (AMSJI®) in patients with severe maxillary atrophy. AMSJI®'s custom design, supported by finite element analysis (FEA), allows precise placement that avoids critical anatomical structures and minimizes complications relative to alternative solutions.
Materials And Methods: Data were gathered through firsthand experiences, direct communications, and insights from international workgroup meetings.

Background: It remains unknown how timing of preoperative intra-articular knee hyaluronic acid (HA) injections impacts risk for developing postoperative periprosthetic joint infection (PJI) following total knee arthroplasty (TKA).
Methods: The PearlDiver Mariner database was utilized to identified patients undergoing primary TKA between 2015 and 2022 who received an HA injection without a corticosteroid injection within 12 months prior to surgery. The HA cohort was matched 1:1 to a control cohort undergoing no preoperative injections (corticosteroid or HA).

The "all-on-four" treatment modality is a treatment in which four implants are surgically placed in the completely edentulous jaw in order to restore immediately loaded implant supported fixed restoration. The aim of the present study was to compare clinical, radiological and prosthetic outcomes of immediately loaded maxillary and mandibular four implant supported cross-arch fixed denture prosthesis. A total of 112 edentulous patients who were rehabilitated for their complete maxillary and mandibular edentulism using All-on-four concept between January 2010 to August 2012 in four private dental clinics were included in this study for retrieve their data for marginal bone loss, implant survival rate, and prosthetic complication for a period of 8 years of follow-up.

Prosthetic bone and joint infections are difficult to treat with varying levels of success with standard therapy. Synthetic calcium sulfate carrier, to which specific antibiotics can be added, can be utilized as an alternative drug delivery system in these cases. We have reviewed clinical outcomes using commercially available pure synthetic calcium sulfate dissolvable beads (Stimulan) loaded with antibiotics in 143 patients undergoing orthopedic surgery for prevention and treatment of joint infection.

However, a paucity of literature exists evaluating the effect of cirrhosis on postoperative outcomes following total shoulder arthroplasty (TSA). The purpose of this study is to evaluate the short-term outcomes following elective primary TSA in patients with cirrhosis compared to matched controls.
