Periodontal tissues and their counterparts around endosseous implants

Abstract

New technology coupled with a better understanding of tissue biology has played a key role in restoring the somewhat tarnished image of implant dentistry, Thanks to carefully conducted longitudinal studies, it has now become clear that the replacement of missing teeth by artificial implants integrated into the living tissues of the jaws is a predictable procedure, as long as certain guidelines are followed in the manufacture of the implant, its placement, its eventual functional loading, and its maintenance. Yet, functional success for a natural tooth is dependent on a number of anatomic, physiologic, and environmental considerations which differ in some important respects from those that insure the functional success of an implant. In this paper, we review the anatomic features of the natural dentition with emphasis on the periodontal tissues, and contrast these characteristics with those that exist around well‐integrated endosseous implants.

Marginal Fit of Implant-Supported All-Ceramic Zirconia Frameworks

“…44,45 Ossteointegrated implants show little mobility; hence, in contrast to the situation on abutment teeth, where a certain degree of misfit of a superstructure may be compensated by the resilience of the periodontium, misfit of FPDs seated on implant may cause a certain stress that is directly transmitted to the surrounding bone. 46 Before performing in vivo studies or applying materials for clinical use, in vitro tests should be undertaken to prove the materials' applicability and performance. In vitro tests can performed in a short period of time and have the advantages of reproducibility and the possibility of standardizing a test parameter.…”

Cytokine Production and Bone Remodeling in Patients wearing Overdentures on Oral Implants

“…Extensive multicenter studies have demonstrated the long-term success of implants, and many anatomical, histological, and cytological data are now available (Berglundh et al,199 1; Listgarten et al, 1991;Preti et al, 1996). From these studies, it has become apparent that the widespread success of clinical implantology is largely determined by the capability of bone to form rigid, load-bearing connections to implants and by the formation of a fibroblast-rich barrier tissue next to the titanium surface, which can protect the peri-implant bone against the oral environment.…”

The influence of surface topography of ceramic abutments on the attachment and proliferation of human oral fibroblasts

“…As in the normal periodontium, the healthy mucosa has an essential role in protecting the peri-implant sulcus from bacterial invasion [19,20]. Regeneration of the attached mucosa around the implant post provides a protective barrier between the oral cavity and the internal environment.…”
