concepts of tissue-integrated prostheses with remarkable functional advantages, innovations have resulted in dental implant solutions spanning the spectrum of dental needs. Current discussions concerning the relative merit of an implant versus a 3-unit fixed partial denture fully illustrate the possibility that single implants represent a bona fide choice for tooth replacement. Interestingly, w...

The aim of this prospective and blind clinical trial was to assess the effectiveness of sealing localized marginal defects of amalgam restoration that were initially scheduled to be replaced. A cohort of twenty six patients with 60 amalgam restorations (n=44Class I and n=16Class II), that presented marginal defects deviating from ideal (Bravo) according to USPHS criteria, were assigned to eithe...

BACKGROUND AND PURPOSE Total ankle replacement is an established surgical procedure in patients with end-stage ankle osteoarthritis. We analyzed complications and medium-term results in patients with simultaneous bilateral total ankle replacement. PATIENTS AND METHODS 10 women and 16 men, mean age 60 (SD 13) years, were followed for a median of 5 (2-10) years. RESULTS There were no intraope...

Replacement of missing dentition is one of the important needs for patients. It is common reason to attend a dental practice for individuals who wish to restore their aesthetics and function1. There are a variety of treatment modalities for the replacement of a single missing tooth i.e. a removable partial denture, a fixed partial denture or an implant supported restoration. Each of these treat...

Dental implants have become the preferred treatment option for missing teeth replacement due to their functional and restorative benefits. However, placing in esthetic zone remains a challenge anatomical factors need optimal emergence profile. The use of custom abutments regenerative techniques this case report resulted successful implant-supported restoration with excellent aesthetic outcomes....

wetlands in the lower reaches of songhua river (lrsr), northeast china, are rich in biodiversityand natural resources, which provide crucial staging and wintering habitats for various endangered species.however, in the past five decades, the size of this wetland area has decreased, and its quality has deteriorated because of increased natural and human activities. wetland restoration is critica...

Implant restorations have become a primary treatment option for the replacement of congenitally missing lateral incisors. The central incisor and canine often erupt in less than optimal positions adjacent to the edentulous lateral incisor space, and therefore preprosthetic orthodontic treatment is frequently required. Derotation of the central incisor and canine, space closure and correction of...

In conjunction with the Permian-Triassic ecologic crisis approximately 250 million years ago, massive dieback of coniferous vegetation resulted in a degradation of terrestrial ecosystems in Europe. A 4- to 5-million-year period of lycopsid dominance followed, and renewed proliferation of conifers did not occur before the transition between Early and Middle Triassic. We document this delayed re-...

Mutant p53 is frequently detected in cancers in which p53 has lost its ability in tumor suppression and gained function in promoting tumor progression. Restoration of p53 functions by replacement of wild-type p53 and inhibition of its degradation or increment of its transcriptional activity has been applied to the prevention and treatment of cancers. Recent evidence indicates that disrupting ce...
