Zirconia dental implants design-where are we now, and where are we heading ? root analogue zirconia implants : a novel approach

الملخص EN

The purpose of this systematic review was to assess the published data concerning zirconia dental implants from various aspects.

Titles and abstracts were screened and articles were selected for full-text reading.

Articles were divided into three groups: 1) studies evaluating the surface modification of zirconia implants, 2) studies on root analogue zirconia implants, 3) studies on a one-piece or two-piece zirconia implant.

The literature searches for articles written in the English language in PubMed Library database from 2004 till December 2018.

The following search terms were utilized for data search: “zirconia implants” NOT “abutment” or “prosthesis”, “zirconia implants” and “zirconia implant design” AND “root analogue zirconia implant”, “one-piece, two-piece zirconia implants”.

The number of potentially relevant articles selected were42.

All the human in vivo clinical, in vitro, animals’ studies were included and discussed under the following subheadings: Surface modification, root analogue zirconia implants, Physical and mechanical properties, the biocompatibility of one-piece and two-piece zirconia implant and Periimplant tissue compatibility.

There is sufficient significant data on various parameters to conclude that zirconia implants with different sizes, shapes and designs are a promising alternative to titanium considering mechanical and biological properties.

Improvement in the reliability of zirconia implants, permitting for unique designs, connections and reconstructions.

Consequently, the clinical performance of zirconia implants is recommended for routine clinical use
