Vikram, The gingival inflammation was due to improperly finished margins, slight ledging and improper care. The problem with the inflammation is that even with curettage, the tissue would shrink gingivally, so another reason why the crowns had to be remade. And, yes, I did go more subgingivally to get better interproximal contour as well as to better support the subgingival tissue. If I have to go subgingivally, I try to not go past 1/2 the distance of the gingival sulcus. Agreed they did not look undercontoured but the preparations were not adequately prepared nor fitted at the labial margins.

Hi Ronald, may I ask few things that was not clear to me? was gingival inflammation due to undercontoured crowns. were they overcontoured labially or interproxima lly? In your preparation, did you go more subgingival than the already existing crown margins? was already existing margins more uneven and rough that might have attracted plaque? from the look of the already existing crown, they dont look undercontoured thanks.

Yasushi, in answers to your questions, we do not use Vaseline inside the custom trays when we make temporaries. Usually the Siltek just allows the material to easily break loose. We use Luxatemp or one of the others depending on the shade we require. Most of the time we cement with Tempbond.

This is great presentation which was shown step by step. May I have questions? Do you use some vaselin jelly inside custom tray when you make temporally restorations? I would like to know the material for temporalozation(=resin & temp. cement ).

In-Office CadCam Integrated Esthetic Implant Dentistry
CADCAM, and CBCT are becoming somehow mandatory for the proper planning, designing and execution of an esthetic implant treatment outcome. Integrating digital diagnosis to plan properly the surgical aspect from hard and soft tissue grafting to implant placement and abutment design and material selection , to final esthetic restoration outcomes is the goal of using this technology with a microsurgical approach.

3-D Smile Designing with a Functional Touch: The Dental GPS Way
In this esthetic driven era, the responsibility of delivering something that is functionally and esthetically acceptable is of utmost importance. Today , we have something called Dental GPS which is a software that is available both in a clinician version and lab version. It is not only able to help us with the simulation of the proposed results in less than 5 minutes but also able to help us print the diagnostic M lines to help us mount the casts (using a digital facebow) for 2D wax ups and / or 3D virtual wax ups for 3D printed models. This presentation will highlight the usage, simplicity and precision of planning and execution using the 3D smile design software.

Multitasking Digital Dentistry - Part 1 of 2
The "Digital Smile Design" is a technique codified and published in 2011 by Christian Coachman and Marcelo Calamita. This approach has radically changed the way we analyze the aesthetics of our patients and at the same time gave the clinician a great tool of communication with the laboratory and with the patient. In recent years, softwares and applications have been introduced on the market in order to simplify the workflow and make more predictable the outcome. The purpose of the lecture is to resume the current concepts about digital aesthetic preview, and to show new trends.

Diagnostic Waxing Transfer From Diagnostic Casts to Soft Tissue Definitive Casts
Fabricating quality anterior esthetic restorations, such as porcelain veneers and crowns, requires the fabrication of a soft tissue definitive cast with removable dies and a hard stone gingiva. This cast is essential to the integration of the definitive restoration with the architecture of the gingiva.

Significance of Crown Shape in the Replacement of a Central Incisor with a Single Implant-Supported Crown

Significance of Crown Shape in the Replacement of a Central Incisor with a Single Implant-Supported Crown
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.
