Objective: This study's goal was to assess the failure rate and peri-implant complications of single-piece implant systems over the course of a one-year follow-up.
Materials And Methods: Patient records were examined retrospectively. 150 single-piece dental implants were analyzed. Clinical results, implant features, and demographic information were gathered. Implant failure, which is characterized as the total loss of osseointegration, served as the key outcome indicator. Patient satisfaction and peri-implant problems were secondary outcomes. Data analysis employed descriptive statistics.
Results: During the one-year follow-up period, the failure rate for single-piece implant systems was 6.7%. The two main factors leading to implant failure were found to be poor osseointegration (60%) and biomechanical overload (40%). 20% of the cases had peri-implant problems, such as peri-implantitis. 85% of the panelists felt that single-piece implants had satisfied their patients.
Conclusion: A 6.7% failure rate in single-piece implant systems was seen in this one-year follow-up investigation. The major causes of implant failure were found to be poor osseointegration and biomechanical loading. In 20% of the cases, peri-implant problems such as peri-implantitis, were noted. There was great patient satisfaction. These results highlight the significance of regulating occlusal forces, optimizing osseointegration, and applying preventive measures to ensure the long-term viability of single-piece implant systems.

To compare two different secondary IOL fixation techniques, either flanged or hooked, regarding the least required force to dislocate the haptic in human corneoscleral donor tissue (CST). Experimental laboratory investigation. The least required dislocation force (LRDF) of two different fixation techniques, namely the flanged haptics (FH, as described by Yamane) and the harpoon haptic technique (HH, as described by Carlevale) were investigated using 20 three-piece IOLs (KOWA PU6AS) and 20 single-piece IOLs (SOLEKO CARLEVALE) fixated to human scleral tissue.

We report a case of spontaneous total iris avulsion that occurred during corneal wound hydration following an uneventful phacoemulsification procedure. An 86-year-old woman underwent cataract surgery on her right eye, during which a single-piece acrylic intraocular lens (Bausch and Lomb Akreos Adapt Advanced Optics, Bausch and Lomb Incorporated, Rochester, NY, USA) was implanted in the bag, and the viscoelastic material was removed. During corneal wound hydration, total iris avulsion was observed, with the iris prolapsing out of the anterior chamber through the main wound.

Purpose: The purpose of this study was to characterize the morphological and immunological aspects of biointegration at the optic-cornea joint of a second-generation synthetic corneal device.
Methods: The initial prototype, single-piece optic-skirt configuration, is constructed from compact and flexible perfluoroalkoxy alkane with porous expanded polytetrafluoroethylene (ePTFE) overlying the skirt to allow skirt-cornea biointegration. The second-generation version was modified to add ePTFE around the optic wall to allow optic-cornea biointegration.

Objectives: This in-vitro study evaluates the accuracy of modular surgical templates used to fully guide implants in combination with bone reduction, performed by expert and students, for complete arch restorations.
Methods: All the procedures were performed by dental students of the final year and an expert clinician, on twelve edentulous mandible models. A virtual implant planning, simulating a complete arch restoration on six implants were performed.
