Implants of homogenous and especially heterogenous bone are more slowly incorporated than autografts and may be rejected. Bone has been treated in various ways in attempts to reduce the incidence of implant rejection while still retaining such osteogenetic properties as it may have, thereby improving its rate and degree of incorporation. Usually pieces of bone have been either decalcified or ma...

Ti implants are good candidates in bone repair. However, how to promote bone formation on their surface and their consequent perfect integration with the surrounding tissue is still a challenge. To overcome such challenge, we propose to form Ti nanorods on their surface to promote the new bone formation around the implants. Here Ti nanorod arrays (TNrs) with different densities were produced on...

Purpose: Implant length, implant surface area, and crown-to-root (c/r) ratio and their relationship to crestal bone levels were analyzed in 2 groups of partially edentulous patients treated with sintered porous-surfaced dental implants. Materials and Methods: One hundred ninety-nine implants were used to restore 74 partially edentulous patients with fixed prostheses. Implants were categorized a...

BACKGROUND Since the introduction of uncemented hip implants, there has been a search for the best surface coating to enhance bone apposition in order to improve retention. The surface coating of the different stems varies between products. The aim was to assess the retention force and bone adaption in two differently coated stems in a weight-bearing goat model. MATERIALS AND METHODS Hydroxya...

Statement: Osteotomies are well-established procedures in oral and maxillofacial surgery for either corrective measures or for gaining access to subjacent hard and soft tissues. Yet surgical reconstruction of bony defects can often be very challenging as thin and fragile bony structures are especially prone to fracture due to bulky cutting tips or massive application of pressure by conventional...

background and aims. resonance frequency analysis (rfa) offers a noninvasive clinical measurement of stability and osseointegration of implants; it is a useful tool to establish implant loading time. the rfa values are represented by a quantitative unit called the implant stability quotient (isq) on a scale from 1 to 100. the aim of the present study was to measure the stability of astra tech a...

Silk Fibroin-Coated Mg Implants for Bone Repair Engineering In article number 2101724, Hui Fang, Chenxi Wang, and co-workers demonstrate an effective O2/N2 hybrid plasma activation technology to modify alloy, achieving a robust organic protein/inorganic metal interface. The silk fibroin-coated implants possess significantly improved adhesion, anti-corrosion biocompatibility, which expands the b...

PURPOSE The aim of this paper was to distinguish what kind of mucosal tissue, measured at the top of the crest can be referred to as thin, medium or thick and its influence on crestal bone loss around dental implants after a 1-year follow-up. MATERIALS AND METHODS Totally 64 implants were evaluated in 26 patients. 32 implants (test group) were placed about 2 mm supracrestally and 32 implants ...

OBJECTIVES To retrospectively evaluate the clinical outcome of tapered, multithreaded implants (Tapered Screw-Vent MTX; Zimmer Dental, Inc, Carlsbad, CA) with an emphasis on periimplant crestal bone status around those placed delayed and immediately in the posterior and anterior maxilla. METHODS Chart reviews were performed on 46 patients who had been treated with 173 implants replacing one o...
