Summary:

Soft tissue problems (ie, gingival recessions) are common in implantology and are often associated with thin soft tissue biotypes or buccally placed implants. Goaslind described 2 types of biotypes commonly found in the natural dentition: thick and thin. It has been suggested that thicker soft tissue biotypes are associated with less tissue recession, higher crestal bone levels, and better aesthetics. A thin tissue biotype has been shown to be more prone to tissue recession. Gingival recession is always associated with alveolar bone dehiscences. Furthermore, there is evidence that thick soft tissue may be protective against crestal bone loss (ie, tissue thickness of ,2.5 mm resulted in crestal bone loss of 1.45 mm vs. thicker tissues had 0.26 mm). This protective effect occurred, despite the supracrestal position of the implant-abutment interface.

Similarities Between an Acellular Alloderm and a Palatal Graft for Tissue Augmentation
Predictable tissue regeneration presents a considerable challenge in the surgical treatment of gingival tissue defects. Soft-tissue augmentation procedures to increase the existing or create a new zone of attached keratinized gingival tissue have classically been performed using the patient's own masticatory mucosa and, more recently, using an acellular dermal allograft as the donor material. This article presents a clinical case whereby an acellular dermal allograft was placed on the buccal surface…

Bipolar Soft Tissue Management & Functional Mock-Ups
Patients desiring a cosmetic smile improvement can present challenges to the dentist when treatment planning. An excessive display of gingiva due to a high lip line often complicates treatment planning and can compromise the final esthetic result when proper planning is not considered prior to finalizing the case. We often have to ask ourselves as we evaluate the patient, do we “lower the river” (increase tooth length incisally), “raise the bridge” (increase tooth length gingivally) or a combination…

Prosthetic Soft Tissue Development From Single to Full Arch Reconstruction
In addition to surgical intervention is the creation of the specific emergence profile that is essential in the aesthetic zone. The emergence profile composed of 2 parts, the abutment and the subgingival part of the crown. The shape of abutment can be individually shaped so that it gives natural appearance and varies individually (depending on the depth, angulation and diameter of the implant). Sometimes it even dictates the implant position. From a surgical perspective, soft tissue height, position and thickness need to be diagnosed and corrected when needed. From the prosthetic point of view, the emergence profile has to be created to mimic the natural appearance and maintained over time in respect to the biological changes. The course teaches step by step how to be successful with implant prosthetics from single tooth, partially edentulous to full arch reconstruction.

The Evolving Role of Soft Tissue Enhancement in Esthetic Reconstructive Dentistry - Part 2 of 3
Soft tissue grafting techniques, new regenerative materials and bioactivators will be highlighted. The expanding role of allograft materials (Perioderm), platelet rich in growth factors (PRGF, PRF), and when to utilize them will be suggested. The ability of these combined protocols to alter the soft tissue profile around natural teeth, implants, and dentulous ridges, will be reviewed as to its critical role in "Complete Esthetics".

Soft tissue grafting is rapidly playing a larger role in restorative, esthetic, and reconstructive dentistry. While conventional grafting techniques have several limitations, newer grafting materials and techniques make it easier for patients to say "yes" to the treatment they truly need and desire. In this webinar, Dr. Wong will perform a step-by-step demonstration using Perioderm to correct multiple gingival recession defects. Soft tissue allografts are quickly becoming a "game changer" in dentistry, making optimum dentistry more than an ideal... it's a reality.

Modern Crown Lengthening: Classification and Clinical Application
Crown lengthening procedures are indicated to provide adequate tooth structure in case of subgingival tooth fracture or caries, uneven gingival level, un-esthetic short crowns due to the tooth wear, inadequate axial height, altered passive eruption ,forced eruption of a single or multiple teeth and finally in case of gingival smile. The treatment modality for esthetic crown lengthening procedure should be based on detail diagnosis in each case because of the multifactorial etiology and because of the type of therapy selected by the clinician, will have a direct implication for the esthetic result.
