Objectives: The aim of this study was to evaluate the primary stability of implants placed immediately after a sinus lift, compared with implants placed in the area treated with a sinus lift 6 months before.
Material And Methods: Patients with a residual bone height of at least 4 mm were treated with a 1-stage procedure (group A) and patients with a residual bone height < 4 mm with a 2-stage approach (group B). Sinus lift was always performed with 50% autogenous bone and 50% deproteinized bovine bone mineral. Data recorded included maximum insertion torque (IT), resonance frequency analysis (RFA) values, and bone density, length, and diameter. It was recorded whether an implant was removed within 6 months after insertion.
Results: Fourteen patients were included in group A and 16 patients in group B; 96 implants were inserted. Mean IT was 23.77 ± 12.63 N·cm in group A and 26.48 ± 20.80 N·cm in group B. Mean RFA was 65.25 ± 4.45 implant stability quotient (ISQ) in group A and 67.92 ± 10.99 ISQ in group B. No statistically significant differences were found. All implants were osseointegrated.
Conclusions: The results show that the implants studied can obtain a sufficient primary stability in both clinical situations without statistically significant differences.

Introduction: Many interventional strategies are commonly used to treat chronic low back pain (CLBP), though few are specifically intended to target the distinct underlying pathomechanisms causing low back pain. Restorative neurostimulation has been suggested as a specific treatment for mechanical CLBP resulting from multifidus dysfunction. In this randomized controlled trial, we report outcomes from a cohort of patients with CLBP associated with multifidus dysfunction treated with restorative neurostimulation compared to those randomized to a control group receiving optimal medical management (OMM) over 1 year.

Background: The purpose of the present case study is to describe the application of a modification of the Biologically-oriented Alveolar Ridge Preservation (BARP) principles in cases of peri-implant bone dehiscence (PIBD) due to a compromised alveolus at immediate implant placement (IIP).
Methods: The technique is based on the stratification of three layers: a deep layer with a collagen sponge (CS) in the apical part of the alveolus (where the buccal bone plate was still present) to support the blood clot; a graft layer to correct the PIBD; and a superficial collagen layer to cover the graft thus providing space and enhancing clot/graft stability. Healing was obtained by primary closure.

Host-guest binding plays a crucial role in the functionality of various systems, and its efficiency is often quantified using the binding free energy, which represents the free-energy difference between the bound and dissociated states. Here, we propose a methodology to compute the binding free energy based on the energy representation (ER) theory of solution, which enables us to evaluate the free-energy difference between the systems of interest with the molecular dynamics (MD) simulations. Unlike the other free-energy methods, such as the Bennett acceptance ratio (BAR), the ER theory does not require the MD simulations for hypothetical intermediate states connecting the systems of interest, leading to reduced computational costs.

Microsaccades, a form of fixational eye movements, help maintain visual stability during stationary observations. This study examines the modulation of microsaccadic rates by various stimulus categories in monkeys and humans during a passive viewing task. Stimulus sets were grouped into four primary categories: human, animal, natural, and man-made.

Aim The primary objective of the study was to evaluate the mid-term implant survivability, rate of revisions, and clinical and functional outcomes following patella resurfacing during total knee arthroplasty (TKA) utilizing posterior stabilized (PS) total knee system (TKS). Methods A prospective, single-arm, multi-center, post-marketing surveillance encompassed patients with end-stage primary knee osteoarthritis (OA) or inflammatory arthritis. The time points of the study included baseline, six weeks, six months, one year, and three years post-operatively.
