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 ).

Treating the Terminal Dentition: A Patient-Center Approach
In patients with terminal dentition esthetic and functional replacement is a necessary objective, but no longer a sufficient-objective: nowadays, due to the clinical and extra clinical characteristics of these patients, management of the therapy is as important as its conclusion. Respect of the principle of autonomy, reduction of treatment length, simplification of surgical procedures and prosthetic management of implant immediate loading are the cornerstones of this philosophy and are the object of this lecture.

The Changing Paradigm of Digital Implant Dentistry: Today’s Technology and Tomorrow’s Concepts - Part 2 of 2
Digital technology has revolutionized implant dentistry but not without frustration. Recent advances with hardware, software, and materials now present integrated solutions for the implant team through planning, placement, and restoration. Single implant treatment will be presented for every-day practice, as well as more advanced partial and fully-edentulous techniques. The most efficient and precise workflows through Keystone and its industry partners will give you concrete digital solutions ready for implementation in your practice. At the conclusion of the lecture the speaker will define some different “team structures” for how the surgeon, dentist, and lab could invest in technology and work together.

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.

Controlled Restorative Treatment of Compromised Anterior Dentition

Controlled Restorative Treatment of Compromised Anterior Dentition
The aesthetic appearance of the maxillary anterior dentition is determined by the relationship between the shape, contour, color, position, and arrangement of the teeth to the healthy labial gingiva and the interdental papillae. When restoring the anterior dentition, the objective of a harmonious natural appearance of the teeth, surrounded by healthy soft tissue, should be achieved through a controlled predictable treatment protocol. In periodontally compromised teeth, the prognosis of each tooth…
