{"title":"The Core of Digital Dentistry: Intraoral Scanners.","authors":"Florin Eggmann, Markus B Blatz","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Intraoral scanners (IOSs) have transformed digital dentistry by enabling the capture of detailed intraoral optical impressions, resulting in high-precision virtual models. This article provides an overview of the technological advancements and emerging applications of IOSs in various dental specialties. Recent innovations have improved IOS speed, resolution, and functionality, eliminating the need for scanning powder and allowing for seamless integration with other digital tools. IOSs are widely used in restorative dentistry for computer-aided design/computer-aided manufacturing of dental restorations, offering accuracy comparable to traditional methods. Additionally, IOSs play critical roles in prosthodontics, orthodontics, and oral and maxillofacial surgery. Automated tooth segmentation and orthodontic landmarking have become more efficient due to advancements in machine learning. However, although IOSs are highly accurate for most dental procedures, they face limitations in edentulous areas and full-arch implant impressions. Efforts to expand their diagnostic capabilities-such as caries detection and the monitoring of soft-tissue levels and tooth wear-are underway, aided by advancements in imaging technologies. As research continues, future developments in IOS technology, including better integration with other digital tools and teledentistry applications, should further enhance its utility in dental care.

Current CAD/CAM techniques incorporate both subtractive and additive (eg, 3D printing) manufacturing methods, with 3D printing offering such benefits as reduced material waste and the ability to produce complex geometries. Much research has focused on the development of hybrid materials that merge the esthetics and durability of ceramics with the high flexural strength, low abrasiveness, and intraoral repairability characteristics of resin composites. Most hybrid ceramics, however, have been optimized for subtractive manufacturing methods, and only a few 3D-printed hybrid materials are available for permanent dental restorations. This case report documents the clinical application of digital technologies in the full-arch rehabilitation of a patient with terminal dentition, highlighting the use of 3D-printed nanoceramic hybrid materials for long-term provisionalization and as a potential permanent solution in the subsequent transition to definitive restorations.

However, in the past its chemical properties in aqueous solution have made it difficult to stabilize with desirable results. The recent development of a novel formulation of 0.454% stannous fluoride stabilized with nitrate and phosphates (SNaP) has resulted in prolonged therapeutic effect without compromising product experience and esthetics.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Dentifrice antibacterial performance in vitro was determined through bacterial bioenergetics measured via rate of oxygen consumption and extracellular acidification in real-time comparing the SNaP toothpaste, a stannous fluoride positive control toothpaste, a non-antibacterial negative control toothpaste, and no treatment. Also, a single- center, randomized, controlled, double-blinded, clinical investigation of 98 subjects was performed to analyze dentifrice antibacterial performance in vivo following twice daily treatment with SNaP toothpaste (n = 48) and non-antibacterial control toothpaste (n = 50). Oral microenvironments, including plaque, tongue, cheek, gum, and saliva, of study participants 12 hours post-brushing were analyzed for bacterial load at baseline, 2 weeks, and 4 weeks.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;In vitro treatment of biofilms with SNaP toothpaste resulted in significant suppression of bacterial respiration and glycolysis compared to a positive control, negative control, and no treatment. In the clinical trial, treatment with SNaP toothpaste showed significantly lower bacterial load in all oral microenvironments 12 hours post-brushing after 2 weeks (all: P less than .01) and 4 weeks (all: P less than .05) compared to non-antibacterial negative control toothpaste. Compared to baseline, SNaP toothpaste significantly reduced bacteria from tongue (P = .007) and saliva (P less than .001) at week 2, and from all microenvironments by week 4 (all: P ≤ .001).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;SNaP toothpaste provided significantly greater and more sustained antibacterial effects than other tested toothpastes. Stannous fluoride, when stabilized in the SNaP formulation, effectively inhibited bacterial respiration and glycolysis in saliva-derived in vitro biofilms. The specific stabilization strategy used in SNaP toothpaste is critical for the antibacterial performance of stannous fluoride, as this formulation was more effective at reducing bacterial metabolic activity than a toothpaste containing the same amount of stannous fluoride stabilized with gluconate. The clinical study supports the in vitro findings by showing that the regular use of SNaP toothpaste leads to a significant and prolonged reduction in viable bacterial counts of five oral microenvironments.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Practical implications: &lt;/strong&gt;The highly stabilized stannous ion in SNaP toothpaste confers potent, sustained antibact","PeriodicalId":72651,"journal":{"name":"Compendium of continuing education in dentistry (Jamesburg, N.J. : 1995)","volume":"45 Suppl 3","pages":"12-19"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142683528","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}
