To determine the status of implant stability, continuous monitoring in an objective and qualitative manner is important. To measure implant stability two different stages are there: Primary and secondary. Primary implant stability at placement is a mechanical phenomenon that is related to the local bone quality and quantity, the type of implant and placement technique used. Primary stability is checked from mechanical engagement with cortical bone. Secondary stability is developed from regeneration and remodeling of the bone and tissue around the implant after insertion and affected by the primary stability, bone formation and remodeling. Implant stability is essential for the time of functional loading. Classical benchmark methods to measure implant stability were radiographs or microscopic analysis, removal torque, push-through and pull-through but due to lack of feasibility, time consumption and ethical reasons other methods have been propounded over period of time like measurement of implant torque, model analysis and most important ISQ which has the ability to monitor osseointegration and the life expectancy of an implant. ISQ is a valuable diagnostic and clinical tool that has far-reaching consequences on implant dentistry and this article throws light on advanced and reliable methods of assessing ISQ.","PeriodicalId":90816,"journal":{"name":"Dentistry (Sunnyvale, Calif.)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48447690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Minimal width of keratinized mucosa (KM) of 2 mm is deemed necessary to facilitate oral hygiene maintenance around the implant and provide hard and soft peri-implant tissue stability. PIS thickness of at least 2 mm is recommended to achieve the esthetic appearance and prevent recessions around implant prosthetic rehabilitation. The autogenous soft tissue grafts can be divided into two groups based on their histological composition—free gingival graft (FGG) and connective tissue graft (CTG). FGG graft is used mainly to increase the width of keratinized mucosa while CTG augment the thickness of PIS. Both grafts are harvested from the same anatomical region—the palate. Alternatively, they can be harvested from the maxillary tuberosity. Soft tissue grafts can be also harvested as pedicle grafts, in case when the soft tissue graft remains attached to the donor site by one side preserving the blood supply from the donor region. Clinically this will result in less shrinkage of the graft postoperatively, improving the outcome of the augmentation procedure. To bypass the drawback connected with FGG or CTG harvesting, substitutional soft tissue grafts have been developed.","PeriodicalId":90816,"journal":{"name":"Dentistry (Sunnyvale, Calif.)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49532850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When this healing occurs with a metal (titanium) fixture on one side, it is called as osseointegration. After extensive studies on this topic, it is found that this procedure occurs in presence of various biologic constituents that are spontaneously released at the site. Thus, to accelerate normal healing after implant placement and make results more predictable, it has been proposed to use these autologous factors in the osteotomy site. Since it is the beginning of a new revolution in dental implantology, right now it is essential to analyze all possible combinations of host conditions, bone quality and quantity and bio factors being used.

Whilst miniscrews need to be mechanically stable during treatment to provide sufficient anchorage and predictable force control, as temporary anchorage devices they need also be easy to remove after orthodontic treatment. These requirements differentiate orthodontic miniscrews from dental implants - which once placed, are not to be removed - and dictate the approach as to how their clinical performance can be optimized. Over the past decade, various titanium surface modifications and improvements in implant surface topography have shown to enhance osseointegration of endosseous dental implants. Some of these techniques have helped provide a similar enhancement of the biomechanical potential of orthodontic miniscrews as well. In this perspective, we present a brief discussion on all such reported techniques followed by a detailed account of the most recently proposed ultraviolet photofunctionalization technique - a novel chair-side surface modification method.","PeriodicalId":90816,"journal":{"name":"Dentistry (Sunnyvale, Calif.)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44427202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fortunately, technological advances applied to dental implantology have allowed us to perform full-arch prosthetic treatments, managing to rehabilitate the form, function, esthetics and lost self-esteem in patients with severe atrophy of the jaws.

Prior to the widespread adoption of implants as standard prosthetic therapy, remaining roots were preserved and used to minimize bone resorption under the removable denture. Root-supported overdentures become less common after the overwhelming clinical studies that emphasize dental implants’ reliability and high success and survival rate. Fixed prostheses cannot be used to treat a severely decreased dentition unless a significant number of implants can be inserted, sufficient bone quantity and quality are available, and the patients can afford the treatment. On the other hand, using strategic implants under existing RPD upgrades the design to a more favorable support type. It improves patient satisfaction with the RPD in speaking, chewing, retention, stability, and RPD support. This improvement could be reached earlier if the patient received immediate loading. Strategic implants can also improve chewing ability, stabilize the occlusion, increase bite force and improve patient oral health-related quality of life. Moreover, better distribution of occlusal forces that may reduce bone resorption may be gained. Furthermore, strategic implants can improve comfort, confidence, and esthetics by reducing the RPD size and removing the retainers from the esthetic zone.","PeriodicalId":90816,"journal":{"name":"Dentistry (Sunnyvale, Calif.)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46153412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Peri-Implantitis Revisited","authors":"A. Shatta, S. Anil","doi":"10.5772/intechopen.100293","DOIUrl":"https://doi.org/10.5772/intechopen.100293","url":null,"abstract":"Dental implants have become a well-accepted treatment option for patients with partial or complete edentulism. The long-term success of the endosseous dental implant depends not only on osseointegration, but on the healthy soft tissue interface that surrounds the implant. Peri-implantitis is defined as an inflammatory process affecting the supporting hard and soft tissue around an implant in function, leading to loss of supporting bone. Peri-implant mucositis has been defined as a reversible inflammatory reaction in the peri-implant mucosa surrounding an osseointegrated dental implant. Peri-implant mucositis is assumed to precede peri-implantitis. Data indicate that patients diagnosed with peri-implant mucositis may develop peri-implantitis, especially in the absence of regular maintenance care. However, the features or conditions characterizing the progression from peri-implant mucositis to peri-implantitis in susceptible patients have not been identified. The most common etiological factors associated with the development of peri-implantitis are the presence of bacterial plaque and host response. The risk factors associated with peri-implant bone loss include smoking combined with IL-1 genotype polymorphism, a history of periodontitis, poor compliance with treatment and oral hygiene practices, the presence of systemic diseases affecting healing, cement left behind following cementation of the crowns, lack of keratinized gingiva, and previous history of implant failure There is strong evidence that there is an increased risk of developing peri-implantitis in patients who have a history of severe periodontitis, poor plaque control, and no regular maintenance care after implant therapy. Management of peri-implantitis generally works on the assumption that there is a primary microbial etiology. Furthermore, it is assumed that micro-organisms and/or their by-products lead to infection of the surrounding tissues and subsequent destruction of the alveolar bone surrounding an implant. A combination of surgical, open debridement, and antimicrobial treatment has been advocated for the treatment of peri-implantitis. Surgical intervention is required once a patient has bleeding on probing, greater than 5 mm of probing depth, and severe bone loss beyond that expected with remodeling. Access flaps require full-thickness elevation of the mucoperiosteum, facilitating debridement and decontamination of the implant surface via hand instruments, ultrasonic tips, or lasers. When necessary, surgical procedures may be used in conjunction with detoxification of the implant surface by mechanical devices, such as high-pressure air powder abrasion or laser.","PeriodicalId":90816,"journal":{"name":"Dentistry (Sunnyvale, Calif.)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41896532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
