{"title":"Injectable technique in treating tooth wear: digitally guided no-prep composite veneers and tabletops. Multidisciplinary approach with a 3-year follow-up.","authors":"David Geštakovski, Ornela Helinger Geštakovski","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The injectable technique is a minimally invasive, fully guided molding procedure that predictably reproduces the functional and esthetic design from the digital model to the final composite restoration. This method utilizes a highly filled flowable composite in combination with a transparent silicone index serving as a mold. Recent advancements in the mechanical and esthetic properties of newly developed flowable composite materials have positioned the injectable technique as a potential treatment option for tooth wear. As a purely additive approach, this technique offers protection by preserving tooth structure while achieving both functional and esthetic goals. A comparison with other direct and indirect techniques is provided. The present case outlines a multidisciplinary approach to the treatment of generalized tooth wear in a young adult patient, with a 3-year follow-up. The step-by-step clinical procedure for both composite veneers and tabletops fabricated using the injectable technique protocol is described. A detailed digital plan is presented, including specific guidelines for designing composite tabletops for oral rehabilitation. Emphasis is placed on the preparation of the final model and the adaptation of the transparent silicone index for optimal intraoral application. Using the double-model technique, the single-veneering concept can be applied, improving index stability and the precision of the interproximal marginal areas, preventing material overflow onto adjacent teeth, and reducing chair time. The advantages of the injectable technique lie in its predictability, repeatability, simplicity, minimal invasiveness, and financial accessibility.

{"title":"Reattaching fractured tooth fragments. The composite rod technique (CRT).","authors":"Irfan Ahmad","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Traumatic dental injury (TDI) involves coronal fractures of the maxillary anterior teeth, a relatively frequent occurrence in children and adolescents. The location in the arch of the maxillary incisors makes them precariously vulnerable to external trauma that requires immediate attention, not only to pacify the emotional anguish of the patient and parents, but also to safeguard the structural integrity of these pivotal teeth that are the cornerstone of dental esthetics. Restitution of TDI is particularly challenging if a patient presents with pulp involvement or vertical root fractures, necessitating both endodontic and restorative intervention or possibly extraction. The key elements for therapy are accurate diagnosis and expediency to alleviate pain, placate psychologic shock, and mitigate social embarrassment due to compromised esthetics. The latter is particularly significant for young patients who may encounter insensitive peer taunting that affects their mental well-being. This article focuses on the work steps for reattaching fractured tooth fragments isolated to enamel and dentin, including those involving the pulp, with a novel, minimally invasive approach called the composite rod technique (CRT) for facilitating the relocation of the fragment, optimizing fracture resistance of the fragment-abutment complex, and restoring anterior esthetics.</p>","PeriodicalId":46271,"journal":{"name":"International Journal of Esthetic Dentistry","volume":"21 4","pages":"346-359"},"PeriodicalIF":1.1,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149197141","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}
