Design of dental implants at materials level: An overview

Abstract

Due to the excellent restoration of masticatory function, satisfaction on aesthetics and other superiorities, dental implants represent an effective method to resolve tooth losing and damaging. Current dental implant systems still have problems waiting to be addressed, and problems are centralized on the materials of implant bodies. This review aims to summarize major developments in the field of dental implant materials, starting with an overview on structures, procedures of dental implants and challenges of implant materials. Next, implant materials are examined in three categories, that is, metals, ceramics, and polymers, their mechanical properties, biocompatibility, and bioactivity are summarized. And as an important aspect, strategies of surface modification are also reviewed, along with some finite element analysis to guiding the research direction of implant materials. Finally, the conclusive remarks are outlined to provide an outlook on the future research directions and prospects of dental implants.

Scaffold-based developmental tissue engineering strategies for ectodermal organ regeneration

“…Complete loss of natural teeth is widespread, particularly affecting older people, mainly caused by dental caries, periodontal disease and genetic disorders [ 65 , 66 ]. Current dental treatments that are being used to replace missing tooth structure or missing teeth are based on conservative therapies such as fillings, made of inert dental materials, fixed dental bridges [ 67 ] or removable dentures [ 68 ] ​and dental implants [ 69 , 70 ]. Different approaches have emerged, such as concepts of regenerative dentistry, that challenge the modern dentistry to step up the dental research and translate the scientific knowledge of understanding the underlying mechanisms of tooth development and the biological processes of healing and repair.…”

Toughening of Bioceramic Composites for Bone Regeneration

“…The classification of bioceramics is generally based on their chemical composition, as well as on the basis of their interaction with natural tissues; thus, bioceramics can be considered as bioinert or bioactive, considering biodegradability as an added value that enables the replacement of damaged bone parts with new ones during the scaffold bioresorption [28][29][30][31][32]. In this respect, recent studies demonstrated that the modulation of composition and textural properties can be considered as a valuable strategy to control material resorption and bone formation [33,34].…”

Errors in Implant Positioning Due to Lack of Planning: A Clinical Case Report of New Prosthetic Materials and Solutions

“…Integrated treatment planning with dental implants is a well-established option [1,2]. Nevertheless, the achievement of the optimal implant position, based on the prosthetic plan, is still a critical consideration in implant-based surgery [1].…”
