PURPOSE: The prevalence of peri-implantitis has increased significantly, forcing clinicians to search for ways to prevent it. Laser-microtextured surfaces promote soft tissue attachment and provide a tight seal around implants. Hence, the aim of this study was to examine the clinical, radiographic, and histologic features of ligature-induced peri-implantitis, as well as the effect of surgical treatment of these induced peri-implantitis lesions on laser-microtextured implants in a controlled animal model...

PURPOSE: The need for dental implants is increasing, and supportive periodontal treatment can achieve long-term success and prevent peri-implantitis. Contributing factors to noncompliance with long-term scheduled supportive periodontal treatment remain unclear. To investigate whether demographic and clinical characteristics are associated with noncompliance, the authors analyzed data for patients who had received dental implants. MATERIALS AND METHODS: The authors recruited patients participating in a supportive periodontal treatment program after receiving permanent prostheses on implants placed from 2005 to 2013...

Stavros Pelekanos, Georgia Pozidi
Reductions in peri-implant bone height have been acknowledged as a normal consequence of implant therapy. Various restorative factors contribute to this phenomenon. One is repeated abutment retightening, which causes a mechanical disruption at the implant-abutment interface, leading to soft tissue recession. Several investigators proposed placement of the definitive abutment after implant placement as a solution to the problem. The definitive use of an intermediate abutment after implant placement seems to positively affect the soft tissue response...

In this 3-year follow-up study, peri-implant bone loss at bone-level implants was evaluated with two definitive abutment heights: 1 mm and 2.5 mm. Peri-implant bone loss was defined as the distance between the implant shoulder and the first bone-to-implant contact from the time of loading to the 36-month follow-up, estimated using periapical radiographs. The bone loss was increased at the time of follow-up, to 1.30 mm (95% confidence interval [CI]: 0.70-1.89 mm; SD = 1.89) and 0.33 mm (95% CI: 0.11-0.55; SD = 0...

The aim of this study was to describe a protocol and analyze the outcomes of immediate replacement of failed implants due to peri-implantitis. A total of 17 patients (mean age: 58 ± 10 years) had 22 failed implants that were immediately replaced. One implant failed 16 months after insertion, resulting in an implant survival rate of 94.7%. The mean follow-up time was 40 ± 16 months (range: 9-52 months) after insertion. Mesial and distal bone loss were 0.89 ± 0.62 mm and 0.97 ± 0.66 mm, respectively. Immediate implant replacement could be considered in the management of implant failure due to peri-implantitis...

Guided bone regeneration has become more predictable due to advances in material sciences. Nevertheless, vertical ridge augmentation (VRA) remains a potential challenge due to the complexity of soft tissue management. This becomes more complicated in the posterior atrophic mandible due to limited access and poorer blood supply. As such, a number of critical elements must be taken into consideration in treatment planning. Anatomical structures potentially jeopardize intraoperative adverse events such as bleeding or neurosensory disturbances...

Our ability of screening broad communities for clinically asymptomatic diseases critically drives population health. Sensory chewing gums are presented targeting the tongue as 24/7 detector allowing diagnosis by "anyone, anywhere, anytime". The chewing gum contains peptide sensors consisting of a protease cleavable linker in between a bitter substance and a microparticle. Matrix metalloproteinases in the oral cavity, as upregulated in peri-implant disease, specifically target the protease cleavable linker while chewing the gum, thereby generating bitterness for detection by the tongue...

STUDY QUESTION: Can supplementation of medium with prolactin (PRL), epidermal growth factor (EGF) and 4-hydroxyestradiol (4-OH-E2) prior to embryo transfer improve implantation potential in mouse blastocysts derived from IVF? SUMMARY ANSWER: Combined treatment with PRL, EGF and 4-OH-E2 improves mouse blastocyst implantation rates, while alone, each factor is ineffective. WHAT IS KNOWN ALREADY: Blastocyst dormancy during delayed implantation caused by ovariectomy is maintained by continued progesterone treatment in mice, and estrogen injection rapidly activates blastocysts to implantation-induced status in vivo...

Successful dental and orthopaedic implant outcomes are determined by the degree of osseointegration. Over the last 60 years, endosseous implants have evolved to stimulate osteogenesis without the need for exogenous biologics like bone morphogenetic proteins. An understanding of the interaction between cells and how cells interact with the physical features characteristics of their environments have has led to the development ofse bioactive implants. Implant surfaces that mimic the inherent chemistry, topography, and hydrophilicity wettability of native bone have been shown to provide cells in the osteoblast lineage cells with the structural cues to promote tissue regeneration and net new bone formation...
