Available in PDF, EPUB and Kindle. Book excerpt: Treatment by means of dental implants has become increasingly common, but it is now recognized that cementation during the restorative phase can be the source of significant problems. This book examines in detail the issues associated with cementation in dental implantology, with a particular focus on residual excess cement and its consequences. It provides reliable guidance on cement selection and use on the basis of the latest scientific research. Among the topics addressed are microbial aspects of cement selection, new abutment designs, aesthetic considerations, margin placement and the role of radiography. The relation of peri-implant disease to residual excess cement is explored in depth and alternatives to the cementation process are also considered. All of the chapters have been written by leading experts in restorative and surgical dental implantology. The information supplied is guaranteed to change the way in which the dentist thinks and practices.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: One of the most common problems for cement-retained implant prosthesis is the undetected cement remnants (UCRs) after cementation, in spite of meticulous cleaning around the margin between abutment and restoration. UCRs can cause chronic inflammation around the implant and lead to peri-implant mucositis or peri-implantitis.Aim: The aim of this study is to evaluate the residual cement after cementation and cleaning of implant supported fixed prosthesis. Factors influencing on the undetected cement remnants were analyzed according to the implant diameter, location, sulcus depth, abutment area and total restoration area.Materials and Methods: Sixty patients were involved in this study with 57 single implant supported prostheses and 4 multiple-unit implant supported prostheses. Excess cement was cleaned by trained clinicians and the restorations were removed for evaluation of the UCRs. Gingival surfaces of the all removed restorations were photographed parallel to the abutment screw hole with 1:1.5 magnifications. To analyze the rate of UCRs to abutment area, Adobe Photoshop CC 2015 (Adobe systems Ltd, Europe, Uxbridge, UK) was used for measurement. Gingival height was analyzed using panoramic view radiograph. Mesial and distal gingival height and fixture length were measured to calculate the estimated sulcus depth.Results: In this study, only 9.23% of screw-cement retained implant restorations had no UCRs. The rate of UCRs was significantly higher in molar than in premolar (p=0.048). Distal gingival height has negative correlation with the rate of UCRs on distal area. The wider the total restoration area was, the higher the rate of UCRs was. Buccal, lingual, and mesial gingival height showed no significant correlation with the rate of UCRS on each surface area.Conclusions and Clinical Implications: Excess cement could be remained undetected after cementation and cleaning of implant restorations, especially using customized abutment. It is necessary for implant dentistry to introduce innovative method of retention of restorations.

Download or read book Evaluation of Surface Morphology Antibacterial Efficacy and Biocompatibility of Dental Cements in Simulated Oral Environment written by Silvia I. Gallegos Alvarez and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Dental cements were used in conventional crown restorations for many decades before being utilized in cement-retained restorations in order to make a connection between the implant body and the crown. Cementation is the preferred restoration method because it eliminates unaesthetic components, aids in the obtainment of correct loading characteristics, and is usually less expensive than screw-retained counterparts. However, the use of dental cements has been a constant source of apprehension due to multiple reports indicating in vitro and in vivo cytotoxicity, and their ability to be contaminated by the oral microbiota. Because of this, residual dental cement is listed as a risk factor for peri-implant disease by the American Academy of Periodontology. Furthermore, since there is not a standard guiding dental cement selection, many clinicians approach it in a subjective manner. It has been established that cement selection is done base on preference, ease of use, and current trends on conventional restorations. Cement selection is further complicated by the lack of cements manufactured specifically for implant restorations. Current approaches for dental cement selection could, therefore, neglect the use of cement compositions that could aid in the success of the restoration. The goal of this study was to evaluate the biocompatibility and antimicrobial effects of various commercial dental cements in order to emphasize the impact dental cement composition can have in the oral environment.

Available in PDF, EPUB and Kindle. Book excerpt: Tooth defects and missing teeth are common oral diseases that threaten the patient’s health, aesthetics, and self-confidence. Prosthodontics is a dental specialty with a long history of providing artificial prostheses to restore or replace the damaged or missing teeth and dentition of patients. Based on type and degree, there are three main categories of tooth damage: tooth defect, partial edentulism, and complete edentulism. Various prosthetic treatments are available for restoration, and each of them has its specific advantages and limitations. This means thect, the patient’s oral and general health condition, and the individual’s expectation. In thiat the decision to pursue prosthetic treatment should be made by fully understanding the characteristics of the defs chapter, background knowledge of the characteristics of tooth defects and edentulism are introduced in combination with commonly used prostheses. Despite the fact that there are no omnipotent prostheses, some general guidelines of prostheses selection are given.

Prado and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: ufffcTo evaluate the incidence and risk factors in well-maintained subjects with dental implants with bioceramic molecular impregnated treatment (Osseanu00ae, Intra-Lock International, Boca Raton, FL, USA) in function in a 5-year period. Aim/Hypotesis: Peri-implantitis is a plaque-induced inflammatory reaction characterized by presence of probing pocket depth and bone loss. There are several implant surface topographies available in the market as well as some hypothesis that showed specific surface topographies can be more susceptible than other. Matherials and Methods: Two hundred and sixty-eight implants of 3.3-5.0 mm width and 8-13mm length were installed in 89 subjects between 2010 and 2011. Implants were functionally loaded after 60-day post-surgery with a provisional restoration and thereafter final restorations in ceramic were delivered. Radiographic bone loss was measured on periapical radiographs after 4, 12, and 60 months. Periodontal parameters as percentage of visible plaque, marginal bleeding, probing depth, clinical attachment level, bleeding on probing and suppuration were also evaluated at 60 months. Technical problems as ceramic fracture and loose of abutment screw were evaluated. The cumulative survival and implant-restoration success were assessed using the Kaplan-Meier survival estimator; Chi-square test was applied to evaluate correlations between the study variables. Results: The mean of radiographical bone loss after 60 months was 1.03mm (u00b1 0.30). Six dental implants were lost due to Peri-implantitis (PD >5mm; BoP and/or sup; Bone loss >4mm); 4 out 6 dental implants were lost in smokers with history of periodontitis. A total of 11 dental implants were lost after 5y - 95.89% of success rate. Incidence of peri-implantitis was 2.23% and mucositis 24.35% (PD>4mm, BoP and no bone loss). However, 4.30% of the remaining implants present risk for peri-implantitis (bone loss >3mm without BoP). Lower incidences of technical problems during the period of evaluation at 5 years were observed (11.23%). Conclusions and Clinical Implications: Within the limitation of this prospective study, dental implants with bioceramic molecular impregnated treatment placed in a well-maintained patient presented higher success rate and low incidence of peri-implant diseases after 5y follow-up.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. 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.
