Book excerpt: Laboratory study comparing the influence of different cements on the color of all-ceramic implant crowns supported by titanium base abutmentsBackgrounds: The esthetic outcome is essential for the overall success of implant therapy. The color appearance of peri-implant soft tissue is one of the key factors influencing the esthetics. It has been often reported that titanium abutment may cause a change in color appearance of the peri-implant mucosa, especially when mucosa thickness is 2mm or less. However, it remains unclear whether the color appearance of the peri-implant mucosa would be influenced by different cements and cementation protocols.The aim of the laboratory study is to evaluate, utilizing spectrophotometers, the influence of different cements on the color of lithium disilicate crowns and the color of peri-implant soft tissue around them. Null hypothesis is distribution of u0394E is the same across different cements. Materials and methods: A case with implant supported screw retained crown on 12 was chosen. The morphology of the peri-implant soft tissue was reconstructed using artificial gingiva on a plastic model. 12 was replaced by a replica.48 monolithic disilicate crowns with identical design were fabricated (3 samples for each group). In 3 of the 15 test groups, 3 temporary cements were used to cement crowns on titanium abutments. In 6 groups, crowns were cemented with 6 different definitive cements on titanium abutments. In another 6 groups, the same 6 cements were used while the abutments were sandblasted. 3 abutments was made using composite die material duplicating the exact shape of the titanium abutment. 3 crowns were cemented with light Try-in paste on the composite die abutments as control groups. A spectrophotometer was used to measure color performance on middel and cervical sites of the crowns, and artificial soft tissue 1mm below the mucosa margin. Readings with CIE Lab color scale were recorded.Results:u0394E between test and control groups were calculated according to the formula: u0394E=(u0394L2+u0394a2+u0394b2)1/2. u0394E mean values calculated were as follows: With titanium abutments: light Variolink Esthetic Try-in pasteu00ae (Ivoclar), 2.52; translucent glue, 1.9; zinc oxide temporary cement (Rely Xu00ae, 3M), 1.4; self-curing resin based cement (HO 0, Multilinku00ae Hybrid Abutment, Ivoclar), 1.39; self-adhesive universal resin cement (A2, RelyXu00ae Unicem, 3M), 2.03; dual-cure resin cement (Clear, Panaviau00aeV5, Kuraray), 2.17; dual-cure resin cement (A2, Panaviau00aeV5, Kuraray), 2.3; dual-cure resin cement (White, Panaviau00aeV5, Kuraray), 1.77; dual-cure resin cement (Opaque, Panaviau00aeV5, Kuraray), 1.73. With sandblasted titanium abutments:self-curing resin based cement (HO 0, Multilinku00ae Hybrid Abutment, Ivoclar), 1.93 self-adhesive universal resin cement (A2, RelyXu00ae Unicem, 3M), 1.85; dual-cure resin cement (Clear, Panaviau00aeV5, Kuraray), 1.98; dual-cure resin cement (A2, Panaviau00aeV5, Kuraray), 1.62; dual-cure resin cement (White, Panaviau00aeV5, Kuraray), 1.87; dual-cure resin cement (Opaque, Panaviau00aeV5, Kuraray), 1.78.Independent-Samples Kruskal-Wallis test was performed to compare the u0394E values across different cements. The significance level was set at 0.05. The null hypothesis was rejected. Within the limitation of the study, the following conclusions can be drawn: 1.tCements with different shade from different brands may lead to different color performance on peri-implant soft tissue around all ceramic crowns cemented on titanium abutments. 2.tMultilink HO 0 showed the most favorable color performance in the current study, followed by Panavia Opaque. 3.tIt appears that cements with more opaque shade lead to smaller color change on the labial surface of both peri-implant mucosa and crown. 4.tThe influence of cements on color performance are different across different part of the crown, and peri-implant mucosa.

Available in PDF, EPUB and Kindle. Book excerpt: This book concisely elucidates the science underlying implant treatment in the aesthetic zone in partially edentulous patients and clearly describes the techniques and protocols used by world-leading experts in the field. The book is divided into four parts that address treatment planning; site preparation (hard and soft tissue augmentation); immediate implant placement and provisional restoration; and the design, fabrication, and delivery of the definitive implant prosthesis. Complex cases of this nature present a significant challenge to even the most well informed and experienced of doctors. Implants in the Aesthetic Zone has been specifically crafted to meet all the needs of the clinician involved in their management, providing a reliable road map for interdisciplinary implant treatment in clinical practice. The authors have been carefully selected from a wide range of fields for their expertise in particular areas of implant science or treatment.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive and up-to-date overview of the restoration of teeth retained through root canal treatment, from the perspective of adhesive dentistry. The challenge of adhesion to root dentin is first explained and guidance provided on assessment of the restorability of endodontically treated teeth. The types of prefabricated passive post are then described in detail. The advantages and disadvantages of each type are outlined, with identification of the factors that influence post selection. Further topics include the ferrule effect, evidence‐based clinical applications of fiber posts and new methods to lute fiber posts to the root canal without dentin adhesives. In addition, frequent myths are identified and dispelled. All aspects are illustrated with clinical and laboratory images, diagrams and high-resolution electron microscopy photographs.

Download or read book Extra Coronal Restorations written by Robert Wassell and published by Springer. This book was released on 2018-07-31 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a state of the art clinical guide to contemporary materials and techniques for the restoration of individual teeth and implants. It fully reflects the important developments in the field over the past 15 years, including in particular the shift away from wholesale use of crowns towards adhesive dentistry and less invasive extra-coronal restorations. The book opens by considering the principles and evidence base relating to the longevity of restorations of teeth and implants. Importantly, it explains how to ensure “a healthy start” and manage future risks. Material choice and aesthetic issues are then discussed, before all aspects of the planning and provision of extra-coronal restorations are examined in depth. The coverage also includes the adaptation of crowns to existing partial dentures. In line with modern dental education, each chapter begins with clinically relevant learning objectives, and helpful clinical tips are highlighted. The book will be of value for senior dental undergraduates, postgraduates, and practicing dentists and its scientific content will be of interest to dental academics.

Download or read book Dental Implant Materials 2019 written by In-Sung Yeo and published by MDPI. This book was released on 2021-03-17 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dental implant materials are advancing in the fusion of various scientific fields. Surface modification technologies for implants have been applied to titanium at the micro-level for about four decades. Now, implant surfaces are being topographically and chemically modified at both the micro- and nano-level. The modification techniques are altering other metals and ceramics, making these materials more biocompatible. Materials for abutments in dental implant systems appear to depend on implant–abutment connection structures. Biomechanical factors, such as friction and preload, influence the development of the abutment materials. Additionally, the surfaces of the abutment materials are important in the soft-tissue attachment, which is being actively investigated. As dental implants have to be functional in human bodies for a long time, numerous materials are being clinically tested as implant-supported restorations. The Special Issue, “Dental Implant Materials 2019”, introduces the creative works of scientists on the current advancements in the field of materials for implant dentistry.
