Illustration in tooth wear and resin-bonded bridges
In restorative dentistry, the lack of occlusal space may lead to the mutilation of healthy tissue in order to provide sufficient space for the restorative material. Noprep dentistry can be achieved by placing high-bite restorations, followed by Simple Orthodontic Extrusion (SOE) of other teeth to close the created open bite. This rapid, partial orthodontic treatment is well accepted by patients as it can be easily performed using simple buttons, and it takes only a few weeks to reestablish occlusal contacts. The SOE technique is a further development of the Dahl concept. It has the advantages without the disadvantages. Two applications of this technique are presented in this article: the treatment of the severe wear of anterior teeth with no-prep palatal veneers made of Polymer-infiltrated Ceramic Network (PICN, “hybrid ceramic”) material and the realization of no-prep zirconia resin-bonded bridges (RBBs) to replace missing lateral incisors. An original 3D-printed resin guide for correctly positioning RBBs and facilitating the removal of excess composite cement is also presented. This work highlights the considerable advantages of multidisciplinary collaboration in the field of minimally invasive dentistry.

Ziel: Ziel dieser Fallserie war die Auswertung der 4-Jahres-Ergebnisse von Implantaten in der ästhetischen Zone, die statisch geführt (static computer-assisted implant surgery, s-CAIS) eingesetzt und ohne Abutmentwechsel (One-Abutment-One-Time-Konzept, OAOT) mit vor der Implantatsetzung angefertigten individuellen Zirkonoxidabutments und zementierten Kronenprovisorien versorgt wurden.
Material und Methode: Zehn Implantate wurden sukzedan in der ästhetischen Zone eingesetzt. Nach digitaler Planung der Implantatchirurgie und prothetischen Versorgung wurden Implantatschablonen bestellt, die zunächst für die Herstellung von definitiven individuellen Zirkonoxidabutments und PMMA-Provisorien verwendet wurden. Anschließend wurden mithilfe der Schablonen die Implantate eingesetzt und sofort mit den prothetischen Komponenten versorgt. Die Implantatergebnisse wurden zum Zeitpunkt der Implantatsetzung sowie 4 Monate und 4 Jahre danach ausgewertet.
Ergebnisse: Alle Implantate konnten erfolgreich mithilfe der Implantatschablonen eingesetzt und mit den definitiven Abutments und Kronenprovisorien versorgt werden. Größere prothetische Komplikationen wurden nicht beobachtet. Nach 4 Jahren lag die Implantatüberlebensrate bei 100 % und es wurden kleinere periimplantäre Sondierungsblutungen, aber sehr stabile periimplantäre Knochenhöhen beobachtet. Der Pink-Esthetic-Score zeigt, dass alle prothetischen Komponenten gut integriert waren und eine stabile periimplantäre Weichgewebesituation vorlag.
Schlussfolgerung: Innerhalb der Grenzen dieser Fallserie zeigen die erzielten Ergebnisse, dass neue digitale Workflows die Anfertigung individueller definitiver Abutments und Provisorien vor der Implantatoperation ermöglichen. Der individualisierte OAOT-Ansatz kann zementbedingte Komplikationen verringern und das ästhetische Ergebnis verbessern, indem die Gewebeheilung durch die prothetischen Komponenten optimiert wird. Allerdings haben sich Protokolle dieser Art inzwischen zu volldigitalen Workflows entwickelt, die zunächst klinische Vergleichsstudien erfordern.

Purpose: The purpose of this study was to evaluate the 2-year outcomes of the one-tooth onetime complete digital workflow, allowing the immediate loading of a single implant in the posterior region with a final CAD/CAM crown made of a polymer-infiltrated ceramic network.
Materials and methods: A series of 10 implants were placed, and an intraoral scan was taken after surgery. A final screw-retained polymer-infiltrated ceramic network crown was manufactured chairside and placed the same day in full occlusion. Marginal peri-implant bone changes and soft tissue health were evaluated, and restoration performance was assessed using FDI World Dental Federation criteria and pink and white aesthetic scores. Patient-reported outcome measures and data on the time required to perform the procedures were collected.
Results: After 2 years, the implant survival rate was 100%. The debonding of one crown from its titanium base led to prosthodontic survival rate of 90% and the remaining crowns were all considered successful. The mean marginal peri-implant bone changes yielded 0.87 mm (standard deviation 0.96 mm) and 0.55 mm (standard deviation 0.53 mm) after 1 and 2 years, respectively. Mild or no inflammation of peri-implant soft tissue was observed in most implants. The total treatment time was 175 minutes and patient-reported outcome measures displayed high patient satisfaction.
Conclusions: This study constitutes the first report examining immediate loading of a single implant in the posterior region with a final crown in occlusion. In this case series, the 2-year outcomes of the one-tooth one-time protocol seem rather promising and fulfilled patient expectations. However, these preliminary results need to be confirmed by randomised controlled trials, and patient selection is likely to be a key factor in the success of this procedure.

Functional and esthetic oral rehabilitation of young patients affected by ectodermal dysplasia is traditionally performed with direct composite restorations, which encounter various limitations. However, recent advances in computer-aided design/computer-assisted manufacturing (CAD/CAM) composites have led to the introduction of high-performance materials. In the present case report, a 9-year-old patient was treated with 20 CAD/CAM partial and peripheral restorations in polymer-infiltrated-ceramic-network material to restore deciduous and permanent teeth. The restorations were minimally invasive, since they did not require any tooth tissue preparation. Appropriate occlusal relationships with increased vertical dimension of occlusion were obtained. Tooth anatomy and esthetics were significantly improved, and chairtime was reduced.
