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

Summary:

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.

Clinical Performance of Porcelain Laminate Veneers: Outcomes of the Aesthetic Pre-evaluative Temporary (APT) Technique

Clinical Performance of Porcelain Laminate Veneers: Outcomes of the Aesthetic Pre-evaluative Temporary (APT) Technique
The article evaluates the long-term clinical performance of porcelain laminate veneers bonded to teeth prepared with the use of an additive mock-up and aesthetic pre-evaluative temporary (APT) technique over a 12-year period. Sixty-six patients were restored with 580 porcelain lamintate veneers. Over 12 years, 42 laminate veneers failed, but when the preparations were limited to the enamel, the failure rate resulting from debonding and microleakage decreased to 0%. Porcelain laminate veneers presented a successful clinical performance in terms of marginal adaptation, discoloration, gingival recession, secondary caries, postoperative sensitivity, and satisfaction with restoration shade at the end of 12 years. The APT technique facilitated diagnosis, communication and preparation providing predictability for the restorative treatment. Limiting the preparation depth to the enamel surface significantly increases the performance of porcelain laminate veneers.

A Refined Digital Workflow in Complete Esthetics
Whether it be analog or digital, the DESIGN of a new smile is the most CREATIVE and critical part of the whole workflow and it starts with a direct mock up or a wax up which will be test driven in the patients mouth. It is the first visual communication between the dentist and the patient, and if it is not executed properly, it may create a negative effect on the patient in terms of loss of confidence and case acceptance. However with the combination of digital and analog tools, today every dentist at any skill level can achieve such amazing smile designs with a touch of a button, without the need of any computer skills.
