Background/purpose: Immediate implant placement (IIP) with and without immediate provisionalization (Ipro) may yield satisfactory results in appropriate indications and treatment, especially in the esthetic zone. The aim of this study was to compare implant stability, marginal bone loss (MBL), survival rates, and patient satisfaction between IIP with Ipro and IIP without Ipro.
Materials And Methods: Seventy patients, each with a failed maxillary anterior tooth, were randomly assigned to IIP with Ipro (Group A: n = 35) or IIP without Ipro (Group B: n = 35). Implant stability quotient (ISQ) and standardized periapical radiographs were performed at surgery and at 3, 6, 9, and 12 months postoperatively to investigate implant stability and MBL, respectively. Survival was assessed 1 year after surgery. Patient satisfaction was evaluated with a visual analogue scale (VAS).
Results: Primary ISQ and MBL were not significantly different between groups A and B immediately after surgery ( > 0.05). Implant survival was 100% in both groups, and only one mechanical complication was observed. Patient satisfaction was good at definitive crown delivery and postoperatively 1-year in both groups. However, the immediate postoperative VAS score in Group A was significantly higher than that in Group B ( < 0.05).
Conclusion: Group A revealed significantly higher secondary ISQ than Group B at postoperatively 3, 6, 9, and 12 months. There were no significant differences between groups A and B in terms of MBL and survival. Notably, patient satisfaction in Group A was significantly higher than in Group B immediately after surgery.

Background: Distal radius fractures are prevalent in small and toy-breed dogs, presenting significant treatment challenges due to complications such as delayed union or non-union. These complications are often exacerbated by reduced vascular density at the distal diaphyseal-metaphyseal junction of the radius, which is vital for bone healing, particularly in toy and small breed dogs. Circular external fixation (CEF) is known for its effectiveness in managing acute and chronic fractures and providing temporary stabilization in humans.

Background: This study investigated the impact of higher interfragmentary compression force (IFCF) on the stability of locking plate fixation in lateral tibial plateau fractures.
Methods: Biomechanical experiments and finite element analysis (FEA) were employed to compare the performance of the AO cancellous lag screw (AOCLS) and a newly developed combined cancellous lag screw (CCLS).
Results: The results demonstrated that the CCLS provided a higher IFCF without the risk of over-screwing, significantly improving fixation stability.

Background: Ultracongruent (UC) total knee replacement (TKR) designs, serving as alternatives to posterior stabilized (PS) and cruciate retaining (CR) designs, lack conclusive evidence regarding posterior femoral rollback. This study aimed to compare intraoperative posterior femoral rollback and maximal knee flexion between UC and PS inserts, addressing the paucity of literature on femoral rollback achieved with UC designs in total knee replacement.
Methods: A consecutive cohort of 20 patients undergoing robotic-assisted primary total knee replacement, posterior femoral rollback and maximal intraoperative knee flexion were assessed.

Bacterial infection and inadequate osseointegration represent significant challenges in the application of titanium (Ti)-based bone implants. Surface modification presents a promising strategy to address these obstacles. Taking advantage of silver ions, black phosphorus nanosheets (BPNs) and polydopamine (PDA), this study developed a versatile platform on the surface of Ti-12Mo-10Zr (TMZ) alloy through a multiple surface modification process, including the anodic oxidation treatment of TMZ alloy, the preparation and addition of silver-loaded BPNs (BPNs/Ag), and the coating with PDA.

In cataract surgery, post-surgical stability of the intraocular lens plays a major role. This study aims to explore how the size and decentration of the capsulorhexis affect intraocular lens decentration and tilt by using numerical methods. Finite element models included zonules, ciliary body, capsular bag, and an IOL with two open-loop haptics were built.
