An Overview of Zirconia Dental Implants: Basic Properties and Clinical Application of Three Cases

Abstract

Due to the possible aesthetic problems of titanium implants, the developments in ceramic implant materials are increasing. Natural tooth colored ceramic implants may be an alternative to overcome aesthetic problems. The purpose of this article is to give information about the basic properties of dental zirconia implants and present 3 cases treated with two-piece zirconia implants. Two-piece zirconia dental implants, 4.0 mm diameter and 11.5 mm in length, were inserted into maxillary incisor region. They were left for 6 months to osseointegrate. Panoramic and periapical radiographs were obtained and examined for bone-implant osseointegration. During the follow-up period the patients were satisfied with their prosthesis and no complication was observed.

A Novel Technique for the Connection of Ceramic and Titanium Implant Components Using Glass Solder Bonding

“…Although, the biocompatibility of titanium with differently structured surfaces has been proven [2,3,4], some problems, such as tissue discoloration and hypersensitivity reactions, have been reported clinically [5,6,7]. Due to their esthetical appearance and their biocompatibility, ceramics constitute a promising alternative implant material [8,9]. On the other hand, failure with dental implants made of zirconia have been reported for single-part [10] as well as multi-part models [11].…”

Reconstruction of Single Tooth Loss with One-Piece and Two-Piece Zirconia Implants: Case Report

“…10 Zirconia implants can be manufactured as one-piece or two-piece designs. [11][12][13][14][15][16] Firstly one-piece implants were introduced. 17 However there are ambitions to fabricate two-piece zirconia comparable to two-piece titanium implants.…”

“…The transmucosal part of one-piece implants is integrated with the implant. 12 Using one-piece implants for everyday practice provides flapless surgery with minimal surgical invasion and provides soft tissue preservation. 24 Placing healing caps with second minor surgery is eliminated, so it is not required to wait for the healing of the soft tissue after the second surgery.…”

“…[1][2][3] Recently, research was oriented towards new generation ceramic materials such as zirconium oxide, which has more favorable mechanical properties (high flexural strength 900-1200Mpa, hardness 1200 Wickers, and Weibull modulus [10][11][12]. Zirconia has high biocompatibility and low…”

Physical vapour deposition of zirconia on titanium: fabrication, characterization and interaction with human osteoblast cells

“…Further development of these materials has enabled their use for fabrication of the enossal dental implants [18]. In general, these ceramic materials are biologically inert, thus the interaction with the surrounding tissue is relatively slow.…”
