Summary:

When utilizing a single implant-supported crown to replace a central incisor, understanding the final shape of the implant restoration is an important factor to help achieve a successful esthetic outcome. In today's dentistry, tooth shape is a critical factor when dental implant prosthesis are considered in the esthetic zone. The goal of this study was to objectively analyze the significance of natural crown shape when replacing a central incisor with a single implant-supported crown. Data analysis revealed that is there is a "black triangle", a diastema, or presence of dental or gingival asymmetry, an additional restoration on the adjacent central incisor is often required in order to fulfill esthetic goals. The additional restoration is highly recommended in situations with a triangular crown shape, while it is suggested in cases of square/tapered and square tooth shapes in the presence of a dental diastema.

Bonding Lithium Disilicate Ceramic to Feather-Edge Tooth Preparations: A Minimally Invasive Treatment Concept
The purpose of this study is to report short-term clinical outcome of a new minimally invasive prosthetic approach utilizing monolithic lithium-disilicate full crowns bonded to feather-edge tooth preparations. This procedure can be considered a further option for the conservative restorative treatment of single elements where a full crown is required.

The "Hybrid Abutment": A New Design for Implant Cemented Restorations in the Esthetic Zones

The "Hybrid Abutment": A New Design for Implant Cemented Restorations in the Esthetic Zones
Cemented implant restorations are widely used by many dentists. The traditional abutment design resembles a natural tooth prepared for a crown with a similar taper and a chamfer finish line. A frequent complication associated with implant restorations in the esthetic zones is the recession of buccal gingiva over time. Abutment morphology, among several other prosthetic factors, may play an important role in the stability of gingival margin in esthetically sensitive areas, but this has never been thoroughly analyzed. With many considerations in mind and recent techniques released, this article proposes the "hybrid abutment: design (HAD), a new design that includes a combination of the two types of features - a feather edge on the buccal side, and a chamfer finish line on the lingual side. This article also presents a rationale for the use of different abutment designs for different situations.

The Role of Digital Technologies & Materials for Full-Arch Implant Reconstruction
In prosthetic rehabilitations, we used for many years codified and widely described protocols in literature, with results that met our expectations and well above those of our patients. It is true that the advent of new technologies has enabled the dental team to use new material and new equipment that facilitated the production of an adaptation and an accuracy of the prosthetic rehabilitation that has, up to now, been difficult to obtain. In this presentation, we will analyze different cases, highlighting the operational differences that they have developed over time, with the increasing knowledge of the new materials and the daily developing of the new software's. It is also described how traditional materials and techniques have been replaced with other innovative new technologies, and how the results obtained with these are systematic and significantly better in updated generations prior.

Predictable Implant Aesthetics Utilizing A Custom Fabricated Provisional Abutment & Impression Coping Premium Member Content

Predictable Implant Aesthetics Utilizing A Custom Fabricated Provisional Abutment & Impression Coping
Mastering the art of predictable implant aesthetics can be challenging. One of the most stressful areas for most dentists is the process of creating a beautiful provisional that will guide tissue and predictably communicate the aesthetic outcome for the final restoration in the aesthetic zone. Combining the use of a custom fabricated provisional abutment, provisional restoration and a custom fabricated impression coping many of the aesthetics challenges can be addressed. This information can then be communicated to the laboratory to ensure the most predictable aesthetic outcome possible. This program is designed to simplify and streamline the entire process of implant provisionalization and impression. This program will provide a systematic, step by step approach to tissue management, provisionalization and impression of implant cases.
