AI Article Synopsis
- Frequent disconnection and reconnection of healing abutments during implant procedures can disrupt soft tissue and lead to bone resorption around implants.
- Suggestions to minimize this disruption include using a one-stage or two-stage protocol to place a definitive abutment immediately during or after implant insertion.
- The paper discusses these protocols and their potential benefits for preserving implant health, but notes that the significance of observed outcomes on bone and soft tissue remains uncertain.
Article Abstract
Typically, healing or temporary abutments are connected and disconnected several times between implant placement and definitive restoration delivery, and soft tissue disruption occurs each time the abutment is disconnected and reconnected. This histologic event is supposed to cause bone resorption around the implant after second-stage surgery. To minimize this clinical scenario, immediately placing and never removing a definitive abutment the day of implant insertion (one-stage protocol) or at second-stage surgery in cases of submerged implants (two-stage protocol) was suggested. This paper details the prosthetic protocol and presents strategies and rationales for placing a definitive abutment the day of implant insertion or at second-stage surgery with cement- and screw-retained restorations. This protocol seems to be an efficient strategy to preserve peri-implant hard and soft tissues. However, positive outcomes in peri-implant bone and soft level changes should be viewed with caution, as their clinical significance is still uncertain.

Purpose: To study the correlation between the levels of inflammatory factors in gingival crevicular fluid and implant stability and prognosis after oral implant restoration.
Methods: A total of 78 patients who underwent oral implant restoration surgery from August 2022 to August 2023 were selected as the experimental group. According to the results of X-ray examination 1 month after implantation, the patients were divided into poor prognosis subgroup(n=33) and good prognosis subgroup(n=45), another 60 healthy subjects who underwent physical examination during the same period were selected as the control group.
Centromedullary nailing during the second stage of induced membrane (Masquelet) for tibia septic nonunion enables bone union to be achieved without increasing the risk of recurrence of infection, with an earlier return to weight-bearing.

Introduction: Septic nonunion is one of the most feared complications in traumatology. Two-stage management using the induced membrane technique is a validated treatment option, but to date there is no consensus on the ideal type of osteosynthesis for the second stage of surgery. The aim of this study was to compare the results of two-stage treatment of tibial septic nonunion, depending on the type of osteosynthesis used.

Background: Occiput-posterior (OP) position is associated with labor arrest, need of operative delivery and failed instrumental vaginal delivery with resulting adverse peripartum outcomes. Vacuum extraction (VE) is the most commonly performed type of instrumental delivery worldwide. This study aimed to investigate the outcome of VE in fetuses with sonographically confirmed OP position prior to the procedure.

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.
