The complete digital workflow in interdisciplinary dentistry.

New digital tools facilitating data acquisition, team communication, computer-assisted diagnostics, and treatment planning as well as the design and fabrication of restorations, guides, stents and devices in general have fundamentally altered key clinical and laboratory steps. The number of new technologies and the amount of new equipment used today to acquire patient data, the software to manipulate this data, and the machines to manufacture devices from it drastically increases all the time, as do the challenges of integrating these systems into a feasible, realistic, and practical workflow. Creating a simple complete digital workflow is key to taking advantage of these digital opportunities and offering their benefits to all patients.

Dental software classification and dento-facial interdisciplinary planning platform.

Objective: Despite all advantages provided by the digital workflow, its application in clinical practice is still more focused on device manufacturing and clinical execution than on treatment planning and communication. The most challenging phases of treatment, comprehensive planning, diagnosis, risk assessment, and decision-making, are still performed without significant assistance from digital technologies. This article proposes a new dental software classification based on the digital workflow timeline, considering the moment of patient's case acceptance as key in this classification, and presents the ideal software tools for each phase.

Different digital tools have been used in clinical practice to assist in the planning and rehabilitation of patients. Some applications (apps) and software programs used in esthetic planning allow simulation of the smile design, improving communication between patients and professionals. Nonetheless, they are usually difficult to use, time-consuming, unattractive to present to the patient, and complicated to link with the 3D workflow.

Layperson's preference of the transverse occlusal plane in asymmetric facial model.

Objective: Facial asymmetries are common, especially deviated nose and chin. The clinician must consider these variables when establishing the smile, placement and angulation of the occlusal plane. The purpose of this article is to determine if nose and chin deviations affect the perception of laypeople towards different angulations of the occlusal plane cant.

Comparing the use of static versus dynamic images to evaluate a smile.

Statement Of Problem: Smile analysis, as part of the overall facial analysis, is an important component of diagnosis and treatment planning in the esthetic rehabilitation of a patient. Most studies that refer to smile analysis are based on static images. A more comprehensive evaluation can be made with dynamic video images that can be stopped at the most appropriate frame to ensure the best static images for analysis.

Occlusal vertical dimension: treatment planning decisions and management considerations.

Changing the occlusal vertical dimension (OVD) has been one of the most controversial issues of restorative dentistry. The modification of the OVD may be indicated whenever it is necessary to harmonize dentofacial esthetics, provide space for planned restorations, and improve occlusal relationships. The OVD should not be considered an immutable reference, but rather a dynamic dimension within a zone of physiological tolerance that can be altered as long as the dentist respects the envelope of function.

The facial flow concept: An organic orofacial analysis-the vertical component.

Orofacial analysis has been used by dentists for many years. The process involves applying mathematical rules, geometric principles, and straight lines to create either parallel or perpendicular references based on the true horizon and/or natural head position. These reference lines guide treatment planning and smile design for restorative treatments to achieve harmony between the new smile and the face.

Layperson's perception of axial midline angulation in asymmetric faces.

Objective: Asymmetric facial features such as a deviated nose and chin are common and known to affect smile esthetics. When presented with these asymmetries, the clinician must consider the impact they will have on the smile design parameters-especially the placement and angulation of the dental midline, which is a common starting point for a case involving smile design. The purpose of this article is to determine if the nose and chin deviations affect the perception of dental midline angulation.

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.
