PURPOSE Since the treatment options for symptomatic total meniscectomy patients are still limited, an anatomically shaped, polycarbonate urethane (PCU), total meniscus replacement was developed. This study evaluates the in vivo performance of the implant in a goat model, with a specific focus on the implant location in the joint, geometrical integrity of the implant and the effect of the implan...

An implant-abutment interface at the alveolar bone crest is associated with sustained peri-implant inflammation; however, whether magnitude of inflammation is proportionally dependent upon interface position remains unknown. This study compared the distribution and density of inflammatory cells surrounding implants with a supracrestal, crestal, or subcrestal implant-abutment interface. All impl...

statement of problem: placement of mini-dental implants when single-tooth restorations are needed and the space is not sufficient to insert a standard diameter implant is indicated. there are many different mini-implant brands with various materials and surface characteristics; however, there are just few studies comparing them with each other. objectives: in this study, finite element analysis...

Although dental implants have become a predictable aspect of tooth replacement in prosthodontic treatment [1, 2, 3, 4, 5, 6], failures of up to 10% are still encountered. Furthermore these failures have been more associated with “soft” bone quality [7], 1985) such as encountered in the maxillary posterior area [8, 9, 10, 11, 12]. In a review article by Esposito et al [13], bone quality and volu...

Peri-implant disease includes the spectrum of conditions that affect the gingiva and underlying bone at the site of implant placement. Despite the tremendous growth in fixed implant utilization over the last two decades, few implant publications address the topic of peri-implant disease from an all-encompassing approach. This article summarizes current research on the topic and provides backgro...

BACKGROUND Dental implant has been successfully used to replace missing teeth. However, in some clinical situations, implant placement may be difficult because of a large bone defect. We designed novel complex biomaterial to simultaneously restore bone and place implant. This complex was incorporated implant into interconnected porous calcium hydroxyapatite (IP-CHA). We then tested this Implant...

Primary implant stability is considered to be a critical factor for obtaining successful osseointegration [1]. Studies using Resonance Frequency Analysis (RFA) have demonstrated that initial implant stability is determined by the density of the bone, the surgical technique used, and the design of the implant [2, 3]. While different implant designs have shown similar results of higher stabilitie...

Implant stability plays a critical role for successful osseointegration, which has been viewed as a direct structural and functional connection existing between bone and the surface of a load-carrying implant(Bränemark, et al. 1977, Sennerby & Roos 1998). Achievement and maintenance of implant stability are prerequisites for successful clinical outcome(Sennerby & Meredith 2008). Therefore, meas...

BACKGROUND Every endosseous dental implant is dependent on an adequate amount and quality of peri-implant hard and soft tissues and their fully functional interaction. The dental implant could fail in cases of insufficient bone and soft tissues or due to a violation of the soft to hard tissues to implant shoulder interface with arising of a secondary bone loss. METHOD To overcome this biologi...

OBJECTIVES Implant design features such as macro- and micro-design may influence overall implant success. Limited information is currently available. Therefore, it is the purpose of this paper to examine these factors such as thread pitch, thread geometry, helix angle, thread depth and width as well as implant crestal module may affect implant stability. SEARCH STRATEGY A literature search wa...
