Ceramic Materials and Technologies Applied to Digital Works in Implant-Supported Restorative Dentistry

Abstract

Computer-aided design and manufacturing technology has been closely associated with implant-supported restoration. The digital system employed for prosthodontic restorations comprises data acquisition, processing, and manufacturing using subtractive or additive methods. As digital implantology has developed, optical scanning, computer-based digital algorithms, fabricating techniques, and numerical control skills have all rapidly improved in terms of their accuracy, which has resulted in the development of new ceramic materials with advanced esthetics and durability for clinical application. This study reviews the application of digital technology in implant-supported dental restoration and explores two globally utilized ceramic restorative materials: Yttria-stabilized tetragonal zirconia polycrystalline and lithium disilicate glass ceramics.

Marginal accuracy of different CAD/CAM monolithic crowns cemented on implant abutments

“…The authors attributed this excessive marginal gap to sinterization shrinkage of thick zirconia material of the full contour monolithic zirconia crowns a fact that may lead to significantly more sintering contraction. Another study (40) recognized this difference in the marginal gap due to the variances between Carbide milling tools that were used to mill zirconia blocks versus diamond tools that were used for e.max blocks. Authors (25)(26)(27)40) added that ;the milling process of zirconia blanks were prepared in a dry field whereas e.max blocks were milled in a wet field.…”

This difference in milling atmosphere explains the variance in marginal precision values made.…”

Function of Nasoalveolar Molding Devices in Bilateral Complete Cleft Lip and Palate: A 3-Dimensional Maxillary Arch Analysis

“…This technology presents good clinical accuracy and excellent patient feedback over conventional methods (Sfondrini et al, 2018). Additionally, 3-D scanners can be easily linked with 3-D printers or millers (Luo et al, 2019), thus allowing a complete digital workflow for different purposes, such as restorative dentistry (Colombo et al, 2019), oral surgery (Pyo et al, 2020), and maxillofacial therapies (Luo et al, 2018).…”

Fabrication of an implant-retained overdenture with ceramic crowns cemented on a polyetherketoneketone framework: A clinical report

“…[3][4][5] However, because these material combinations have been prone to technical complications, 6 alternatives have been proposed. 7,8 Computeraided design and computer-aided manufacturing (CAD-CAM) technologies have enabled the use ofmonolithic zirconia, carbon fiber, and high-performance polymers [9][10][11][12][13][14] such as polyetherketoneketone (PEKK). Its use in dentistry has increased because of its biocompatibility.…”
