Facially generated and cephalometric guided 3D digital design for complete mouth implant rehabilitation: A clinical report

Harmony among the teeth, lips, and facial components is the goal of prosthodontic treatment, whether performed by conventional or digital workflow methods. This clinical report describes a facial approach to planning computer-guided surgery and immediate computer-aided designed and computer-aided manufactured (CAD-CAM) interim complete-arch fixed dental prostheses on immediately placed dental implants with a digital workflow. A single clinical appointment for data collection included dentofacial documentation with photographs and videos. On these photographs, facial reference lines were drawn to create a smile frame. This digital smile design and sagittal cephalometric analysis were merged with 3-dimensional scanned casts and a cone beam computed tomographic file in virtual planning software, thus guiding virtual waxing and implant positioning. Computer-guided implant surgery and CAD-CAM interim dental prostheses allowed esthetic and functional rehabilitation in a predictable manner and integrated with the patients face.

Dynamic Documentation of the Smile and the 2D/3D Digital Smile Design Process

Medical and dental histories, clinical examination, study models, and photographs provide the data for a proper diagnosis and the treatment plan for esthetic dentistry. However, they do not offer all the information necessary to analyze the smile and create harmony with the lips and face without excessive intraoral adjustments. Dentolabial parameters vary according to lip dynamics and are influenced by both a static posed smile and a smile in motion as captured in video. This article describes a documentation protocol using smartphone videos to improve the analysis, smile design decisions, and elaboration of a 2D smile frame that will guide the 3D digital smile design project. The use of dynamic documentation of the smile (DDS) allows esthetic rehabilitative planning from a facial perspective, improvement of communication with the patient, integration between the specialists, and the predictable quality of the treatments.

The influence of tooth color on preparation design for laminate veneers from a minimally invasive perspective: case report.

Various types of dental preparations for laminate veneers have been proposed,depending on factors such as the properties of the ceramic material, remaining dental structure color, need for altering the dental contour, laboratory fabrication technique, and occlusal relationships. Clinical observations of successes and failures associated with the development of techniques and materials have allowed some safe parameters to be delineated for effectively performing dental preparations for ceramic veneers or even placing veneers without any preparation. This article describes the use of an additive diagnostic wax-up that is transferred to the mouth by means of an intraoral mock-up (aesthetic pre-evaluative temporary) with associated mathematic parameters to guide dental preparations. This technique, called Do the Math and presented here in the form of a clinical case report, aims to avoid excessive or incorrect tooth preparation by indicating the exact amount and location of the tooth reduction necessary to attain the desired color and shape.

De reconstructie van de witte en roze esthetiek

SamenvattingIn de afgelopen vijftien jaar zijn procedures ontwikkeld die het mogelijk maken de driedimensionele structuur van harde en zachte weefsels met succes te herstellen. Echter in bepaalde gevallen zijn de resultaten in esthetisch en functioneel opzicht onvoorspelbaar en teleurstellend, zelfs wanneer bot- en gingivatransplantaten worden aangebracht en orthodontische behandeling plaatsvindt (afb. 1 en 2).
