The debate between screw- versus cement-retained implant prostheses has long been discussed but the best type of implant prosthesis remains controversial among practitioners. An understanding of their properties will help the clinician in selecting the ideal prosthesis for each clinical case while promoting final esthetic outcomes. With the evolving technology and knowledge, an update of the current trends is necessary. This article provides an overview of the different characteristics of screw- and cement-retained implant restorations, and how they may influence the esthetics, retrievability, retention, passivity, occlusion, accessibility, cost, and provisional restorations. Problems and complications frequently encountered are discussed and treatment solutions are proposed.
The mean GCF biomarker levels for IL-1beta and MMP-8 were most significantly elevated in T1DM subjects compared with healthy individuals during EG, not resulting from differences in the mean PI or microbial composition.
The influence of tissue biotype in natural dentition is already well demonstrated in the literature, with numerous articles showing that thicker tissue is a preferred biotype for optimal surgical and prosthetic outcomes. In this same line of thought, current studies are directed to explore whether mucosal thickness would have similar implications around dental implants. The purpose of this review was to investigate the effects of soft tissue biotype in relation to success of implant therapy. The influence of tissue biotype was divided into 3 main categories: its relationship with periimplant mucosa and the underlying bone, immediate implant placement, and restorative outcomes. Soft tissue biotype is an important parameter to consider in achieving esthetic implant restoration, improving immediate implant success, and preventing future mucosal recession.
In this proof-of-concept investigation, we identified specific biomarker and microbial signatures that are associated with gingival inflammation (ClinicalTrials.gov number NCT00980525).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
