This article presents the results of a scanning electron microscope (SEM) analysis of the surface of an acrylic custom provisional abutment following first disconnection from a post-extraction immediate implant placement. An implant was placed immediately after extraction, the site was grafted, and a barrier membrane was adapted for graft containment. A custom acrylic shell was then relined, polished, and steam-cleaned prior to being screwed onto the implant. After 5 months of undisturbed healing, the custom provisional abutment was disconnected for the first time and processed for SEM examination...

Due to the increasing adoption of immediate implantation strategies and the rapid development of the computer aided design/computer aided manufacturing technology, a therapeutic concept based on patient-specific implant dentistry has recently been reintroduced by many researchers. However, little information is available on the designs of custom-made dental implant systems, especially their biomechanical behavior. The influence of the custom-made implant designs on the biomechanical performance for both an immediate and a delayed loading protocol in the maxillary esthetic zone was evaluated by means of the finite element (FE) method...

There are recent reports of hybrid tissue-fabric materials with good performance-high biocompatibility and high mechanical strength. In this study, we demonstrate the capability of a hybrid material as a long-term filter for blood proteins. Polyester fabrics were implanted into rats to fabricate hybrid tissue-fabric material sheets. The hybrid materials comprised biological tissue grown on the fabric. The materials were extracted from the rat's body, approximately 100 days post-implantation. The tissues were decellularized to prevent immunological rejection...

S Mashouf, H Safigholi, T Merino, A Soliman, A Ravi, G Morton, W Song
PURPOSE: There is strong evidence relating post-implant dosimetry for low-dose-rate (LDR) prostate seed brachytherapy to local control rates. The delineation of the prostate on CT images, however, represents a challenge due to the lack of soft tissue contrast in order to identify the prostate borders. This study aims at quantifying the sensitivity of clinically relevant dosimetric parameters to uncertainty in the contouring of prostate. METHODS: CT images, post-op plans and contours of a cohort of patients (n=43) (low risk=55...

PURPOSE: This study aims at developing an MRI-only workflow for post-implant dosimetry of the prostate LDR brachytherapy seeds. The specific goal here is to develop a post-processing algorithm to produce positive contrast for the seeds and prostatic calcifications and differentiate between them on MR images. METHODS: An agar-based phantom incorporating four dummy seeds (I-125) and five calcifications of different sizes (from sheep cortical bone) was constructed...

S Park, Y Le, D Song, J Lee
PURPOSE: For post-implant dosimetric assessment after prostate brachytherapy, CT-MR fusion approach has been advocated due to the superior accuracy on both seeds localization and soft tissue delineation. However, CT deposits additional radiation to the patient, and seed identification in CT requires manual review and correction. In this study, we propose an accurate, low-dose, and cost-effective post-implant dosimetry approach based on X-ray and MRI. METHODS: Implanted seeds are reconstructed using only three X-ray fluoroscopy images by solving a combinatorial optimization problem...

BACKGROUND: Patients with congenital heart defects (CHD) often present more challenges to pacing therapy due to anatomy than those without CHD. The lumenless, 4.1Fr diameter M3830 pacing lead (Medtronic, Inc., Minneapolis, MN, USA), approved for use in 2005, has, to date, reported to have excellent short-term (<6 years) lead performance. Unfortunately, very long-term performance is unknown, especially among CHD patients and with implants at alternate pacing (AP) sites. This study reports a 10-year clinical experience with the M3830 lead...

In this article, Broussonetia kazinoki (BK) powdery extract is utilized to modify the silk fibroin (SF) scaffold and applied to the bone defect area. The BK/SF scaffold is an efficient cell carrier which promotes cell proliferation and osteogenic differentiation of rBMSCs (bone marrow derived mesenchymal stem cells). We confirmed biocompatibility and osteogenic differentiation capacity of BK/SF scaffolds compared to pristine SF scaffold in both in vitro and in vivo evaluation. Gene expression related to osteogenic differentiation and bone regeneration significantly upregulated in the BK/SF scaffold group...

The key to achieving pleasing esthetics in implant dentistry is a thorough understanding of the biological processes driving dimensional bone and soft tissue alterations post-extraction. The aim of the present report is first to characterize the extent of bone and soft tissue changes post-extraction and second to identify potential factors influencing tissue preservation in order to facilitate successful treatment outcomes. The facial bone wall thickness has been identified as the most critical factor influencing bone resorption and can be used as a prognostic tool in order to identify sites at risk for future facial bone loss subsequent to tooth extraction...

Implant placement in post-extraction sites of single teeth in the esthetic zone has been a topic of great interest in the field of implant dentistry since 1990. Triggered by the development of guided bone regeneration, the concept of immediate implant placement became quite popular in the 1990s. In the past 12 years, however, the dental community has begun to focus increasingly on the esthetic outcomes of post-extraction implant placement and several studies indicated a significant risk for the development of mucosal recessions with immediate implants...
