post extraction implant

The pursuit of predictable implant success in the aesthetic zone continues as technology develops. Creating stable marginal bone and an optimal peri-implant mucosal environment is the foundation for a long-term healthy and aesthetic implant treatment outcome. Tissue stability is dependent on multiple factors, including the regenerative materials used to create the peri-implant supporting tissues and maintain the tissue volume. The present study aims to describe a technique that combines a flapless approach to extract hopeless teeth in the aesthetic zone and implant insertion using an acellular dermal matrix placed to contain the coronal aspect of an innovative ossifying collagen scaffold designed to promote neoformation of vital native bone...

Background The use of polypropylene mesh in laparoscopic sacrocolpopexy (LSC) is a common treatment for pelvic organ prolapse (POP). Despite its widespread application, postoperative complications such as mesh pain and infection sometimes necessitate the removal of the mesh. However, it remains unclear in which cases mesh removal is warranted. Our research focused on the pathological changes at the sacral fixation point of the mesh. We sought to evaluate the pathological alterations of the sacral mesh removed through an innovative approach of transvaginal natural orifice transluminal endoscopic surgery (vNOTES)...

Group I received immediate implant placement (IIP) without grafting. Group II received IIP with ATBG filling the gap around IIP...

Alzheimer's disease (AD) is a major progressive neurodegenerative disorder of the aging population. High post-menopausal levels of the pituitary gonadotropin follicle-stimulating hormone (FSH) are strongly associated with the onset of AD, and we have shown recently that FSH directly activates the hippocampal Fshr to drive AD-like pathology and memory loss in mice. To establish a role for FSH in memory loss, we used female 3xTg;Fshr +/+ , 3xTg;Fshr +/- and 3xTg;Fshr -/- mice that were either left unoperated or underwent sham surgery or ovariectomy at 8 weeks of age...

Dental pulp stem/stromal cells (DPSCs) are fibroblast-like, neural crest-derived, and multipotent cells that can differentiate into several lineages. They are relatively easy to isolate from healthy and inflamed pulps, with little ethical concerns and can be successfully cryopreserved and thawed. The therapeutic effects of DPSCs derived from animal or human sources have been extensively studied through in-vitro and in-vivo animal experiments and the findings indicated that DPSCs are effective not only for dental diseases but also for systemic diseases...

BACKGROUND: To investigate the change in the distance between corneal apex and pupil center after small-incision lenticule extraction (SMILE) or implantable collamer lens (ICL) implantation and its correlation with surgical-induced astigmatism (SIA). METHODS: This study included patients who had undergone SMILE (n = 112) or ICL implantation (n = 110) to correct myopia and myopic astigmatism. The angle kappa was measured using a Scheimpflug imaging device (Pentacam) and represented as Cartesian values between the pupil center and the corneal vertex (X, Y) and chord u ([Formula: see text]orientation), and was compared pre- and post-operative...

BACKGROUND: Placental mediated pregnancy complications (PMPC) are common, often recurring, and pose a significant health risk to mother and fetus. Evidence suggests that the hypercoagulable state associated with many PMPC, could reflect reduced expression of Annexin 5 (ANXA5), a naturally occurring anticoagulant protein in placental tissue. The ANXA5 M2 haplotype is a genetic variant, which results in reduced expression of ANXA5 protein. M2 haplotype carrier couples may therefore be at increased risk of PMPC...

INTRODUCTION: Breast augmentation, a popular cosmetic surgery using devices like silicone implants, can lead to a common issue called capsular contracture (CC). This condition involves the formation of fibrous tissue around the implants and can be influenced by variables like immunological and bacterial factors. This study aimed to explore the impact of autoimmune diseases (ADs) on CC along with other factors influencing future clinical decisions. METHODS: A systematic review of electronic databases was conducted using PubMed, Web of Science, Scopus, EMBASE, and involving adult patients (>18) with CC and ADs after breast surgery using MeSH terminology using a broad search strategy...

Accurate and reliable estimation of the pelvic tilt is one of the essential pre-planning factors for total hip arthroplasty to prevent common post-operative complications such as implant impingement and dislocation. Inspired by the latest advances in deep learning-based systems, our focus in this paper has been to present an innovative and accurate method for estimating the functional pelvic tilt (PT) from a standing anterior-posterior (AP) radiography image. We introduce an encoder-decoder-style network based on a concurrent learning approach called VGG-UNET (VGG embedded in U-NET), where a deep fully convolutional network known as VGG is embedded at the encoder part of an image segmentation network, i...

BACKGROUND: Social media has become a dominant educational resource for breast reconstruction patients. Rather than passively consuming information, patients interact directly with other users and healthcare professionals. While online information for breast reconstruction has been analyzed previously, a robust analysis of patient questions on online forums has not been conducted. In this study, the authors used a machine learning approach to analyze and categorize online patient questions regarding breast reconstruction...

INTRODUCTION: Permanent liquor diversion is associated with a high risk of failure and often requires re-intervention. The ventriculo-gallbladder shunt (VGS) has been recognized as a last-resort alternative for treating hydrocephalus when the peritoneum or other distal sites are no longer suitable for receiving shunts. This article aims to report a case from a neurosurgery referral service in Brazil and review the literature on this issue. METHODS: A systematic literature review was conducted in accordance with the PRISMA statement...

This case series assessed the efficacy of Orthodontic Implant Site Development with Labial Root Torque (OISD-LRT) as a nonsurgical technique for addressing labial bone deficiencies in seven patients. The procedure involved strategically placing a multi-bracket of 2-3 mm apically on the hopeless teeth, gradually shifting them with Ni-Ti wires at the rate of 2 mm per month and maintaining overcorrection for 2 months before extraction. OISD-LRT consistently augmented tissue for flapless guided implant surgery, with an average treatment duration of 404Å}311...

Reports of implant fixtures dislocating into the maxillary sinus during sinus graft procedures are well-documented. However, cases of fixtures migrating into the sinus long after placement have yet to be reported. This case report details the surgical extraction of a displaced screw and cement-retained prosthesis, including a fixture and its abutment, from the maxillary sinus after a minimum of 5 years under functional load. The extracted implant was subsequently examined using scanning electron microscopy and energy dispersive x-ray spectroscopy...

Post-extraction alveolar bone atrophy greatly hinders the subsequent orthodontic tooth movement (OTM) or implant placement. In this study, we synthesized biodegradable bifunctional bioactive calcium phosphorus nanoflowers (NFs) loaded with abaloparatide (ABL), namely ABL@NFs, to achieve spatiotemporal management for alveolar bone regeneration. The NFs exhibited a porous hierarchical structure, high drug encapsulation efficacy, and desirable biocompatibility. ABL was initially released to recruit stem cells, followed by sustained release of Ca2+ and PO4 3- for in situ interface mineralization, establishing an osteogenic "biomineralized environment"...
