Durch die digitale Zahnmedizin haben sich neue Wege des Restaurationsdesigns eröffnet. Die Autoren beleuchten den aktuellen Stand des Designs von Zirkonrestaurationen unter Berücksichtigung verschiedener Erfolgskriterien. Dargestellt werden das monolithische, das reduzierte und das vollanatomische Restaurationsdesign von Zirkonrestaurationen anhand...

Aim: The purpose of this systematic review was to assess the clinical performance of implant-supported monolithic all-ceramic single- and multi-unit restorations. Materials and methods: The electronic databases of MEDLINE via PubMed, the Cochrane Library (CENTRAL) and EMBASE were searched for clinical studies on monolithic all-ceramic single and mu...

Digital technologies are increasingly used in implant dentistry. Every treat-ment step can be planned digitally, which results in a treatment outcome that is less invasive and more precise and efficient. Innovative computer-aided design/computer-assisted manufacturing (CAD/CAM) materials for the chairside application expand the digital workflow fro...

Recently, hybrid materials have been introduced to the dental market. Together with computer-assisted design/computer-assisted manufacturing (CAD/CAM) composite resins, they form a new class of dental CAD/CAM materials that combine the positive effects of ceramics and composites. As bonding is essential for their clinical longevity, it is crucial t...

Hybrid materials are a recent addition to the dental armamentarium for computer-assisted design/ computer-assisted manufacturing (CAD/CAM)-based restorative dentistry. They are intended to provide dentists with the capability of restoring single teeth in one appointment with a material that emulates the structure and physical properties of natural...

In der Implantologie finden digitale Technologien ein immer größer werdendes Anwendungsgebiet. Die einzelnen Arbeitsschritte können digital geplant werden und resultieren somit in präzisen, effizienten und weniger invasiven Behandlungsergebnissen. Innovative CAD/CAM-Werkstoffe, die auch chairside bearbeitbar sind, erweitern den digitalisierten Work...

Die Akzeptanz von Patienten, langwierige Behandlungskonzepte mit vielen Terminen auf sich zu nehmen, sinkt stetig. Verschiedenste Konzepte zur Alveolenbehandlung oder Sofortimplantation, im Idealfall auch mit sofortiger Versorgung des Implantates, haben sich in den letzten Jahren etabliert. Im vorliegenden Fortbildungsartikel verweisen die Autoren...

Objective: This study investigated the effect of different surface treatments on the bond strength of two different luting agents to a hybrid ceramic material. Methods: A total of 160 specimens (10 x 10 x 2 mm) of a CAD/CAM hybrid ceramic (VITA ENAMIC, Vita Zahnfabrik) were randomly divided into 8 groups (n = 20), based on the respective surface...

Traditional esthetic guidelines and denture-tooth selection protocols suggest a correlation between a patient's face and anterior tooth shapes. This study examined the correlation between face shape, maxilla shape, and maxillary anterior tooth form with fully automated algorithms. Three-dimensional digital datasets of the faces and maxillae were ob...

This clinical study examined objective smile parameters in the natural anterior dentition. Standardized intraoral and extraoral photographs were taken of 106 Caucasian adults (54 women, 52 men) with a healthy dentition. The following parameters were analyzed: correlation of dental and facial midline, upper lip position and curvature, relationship o...

Statement of the ProblemResin bonding is essential for clinical longevity of indirect restorations. Especially in light of the increasing popularity of computer-aided design/computer-aided manufacturing-fabricated indirect restorations, there is a need to assess optimal bonding protocols for new ceramic/polymer materials and indirect composites.Pur...

Derzeit entwickeln sich digitale Technologien in der Zahnmedizin rasant weiter. Zeitgleich wurde eine Reihe innovativer Werkstoffe in den Markt eingeführt, die auf einer Kombination bestehender vollkeramischer Systeme mit Polymermaterialien basieren. Die zunehmende Digitalisierung und neue, komplexe Möglichkeiten in der restaurativen Zahnmedizin st...

This study examined the correlation between maxillary anterior tooth form and gender with three-dimensional data. Three-dimensional digital models of the area between the maxillary right central incisor and the maxillary right canine were obtained from 120 Caucasian subjects (60 males and 60 females) with healthy dentitions. Correlation between gen...

Minimally invasive treatment modalities allow for the preservation of sound tooth substance. However, by limiting the preparation to the extent of a defect, the transition between restoration and natural tooth may be moved to more visible areas. The materials available for the restoration of a limited defect in the anterior area are either resin co...

Aufgrund des wachsenden Wunsches der Patienten nach vollkeramischem Zahnersatz wurde in den letzten Jahrzehnten eine Reihe vollkeramischer Systeme in den Markt eingeführt. Neben der Vollkeramik entwickeln sich derzeit insbesondere digitale Technologien in der Zahnmedizin rasant weiter. Die Entwicklung eines universell einsetzbaren Werkstoffs und ei...

This article illustrates the surgical and prosthetic rehabilitation of an extensive defect in the area of a mandibular lateral incisor following explantation of a dental implant. Bone and soft tissue defects existed after removal of the implant. Guided bone regeneration, a subepithelial connective tissue graft, and gradual pontic contouring were us...

To determine the influence of solvents on gutta-percha and sealer remaining on root canal walls and in dentinal tubules. The root canals of 70 teeth were prepared chemomechanically to apical size 40. In group 1 (n = 10; control group), the canals remained unfilled. In groups 2-4 (n = 20 each), the canals were filled using lateral compaction with gu...
