Summary:
Failure of a natural tooth may not permit placement of
an implant at the time of extraction due to insufficiency
in available bone to house the implant. Reconstruction
of the extraction socket frequently involves both hard
and soft tissue augmentation to provide a site that can house
the implant and ridge contours that mimic the adjacent natural
anatomy. This situation becomes more problematic in the
maxillary anterior due to the anatomy and the lower density of
the bone of the premaxilla.
The solution is the interpositional vascularized augmentation
neogenesis (IVAN), which consists of hard tissue grafts, various
barrier membranes, and closure with the pediculated connective
tissue graft (PCTG). The modified IVAN (mIVAN) technique
achieves the necessary goals and may be used in both delayed
and immediate placement situations.

Similarities Between an Acellular Dermal Allograft 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…

Modified IVAN Technique: Long-Term Follow-Up of 20 Cases Over 2 to 11 Years
When natural teeth fail, frequently there is a loss of hard and soft tissue. This may complicate subsequent dental implant placement by
creating insufficient bone to house the implant. This also occurs when the tooth has been missing for an extended period, especially in the
premaxilla, where the bone is less dense and often lacks sufficient volume of facial bone. Site reconstruction to accommodate implant
placement often requires both hard and soft tissue augmentation. The modified interpositional vascularized augmentation neogenesis
(mIVAN) technique achieves the desired treatment goals in both delayed and immediate placement scenarios. The technique will be
discussed as well as the long-term follow-up on 20 cases.

Modern Day Esthetic Challenges with Implants in the Esthetic Zone
Current trends in implant therapy advocate clinical techniques thereby allowing treatment efficiency consisting of condensed clinical procedures, fewer patient appointments, and shortened overall treatment time. Even though there is overwhelming literature to support positive outcomes in regards to implant survival through immediate implant therapy and tooth replacement strategies, esthetics questions still loom, specifically how to handle multiple tooth sites in the esthetic zone.
This presentation will address treatment planning strategies with multiple tooth sites incorporating teeth, immediate implants with tooth replacement, and pontics in the esthetic zone. Innovations in implant macro design, to achieve more consistent screw-retained definitive restorations, and devices / strategies in provisional restoration fabrication to save time will be presented.

Managing Esthetic Implant Complications
Dental implant success today is judged not only by osseointegration but also by bone, tissue stability and of course long term esthetic results. Cosmetic predictability can often be difficult to attain, and esthetic implant failures can be multifactorial and patient management issues. Once esthetic implant failures occur, many cannot be fully corrected. Some complications must be addressed by an interdisciplinary dental team. In this summary of case reports, surgical considerations are provided, including cases of facial asymmetry/recession due to facial implant placement or bone loss resulting from technique/treatment failures, as well as papillary deficiencies. Restorative considerations for correcting failures are also discussed.

Critical Concepts in Implant and Gingival Surgery; Flap Designs, Suture Techniques and Soft Tissue Management
This presentation by the Troeltzsch Brothers features the fundamentals of surgical procedures in the oral cavity. Highlighted are the basic concepts we all must integrate into our daily clinical practice. A discussion of the essential anatomic guidelines as they relate to flap design options and indications are emphasized. Furthermore, material selection, sutures and techniques of wound closures are clearly addressed. Critical solutions to common surgical complications are also described.
This lecture is intended for surgical beginners as well as experienced clinicians who want to update their surgical knowledge. These fundamentals are also very popular in the hands-on courses given by the Troeltzsch brothers.

Diagnosis, Planning, & Treatment of Altered Passive Eruption; From a Periodontists Perspective
This presentation will teach how to diagnose cases of altered passive eruption based on the radiographic evaluation (with peri-apical rx and CBCT) and how to plan and document a surgical procedure aimed to ‘uncover’ the beautiful and natural hidden enamel. In a world where esthetics is becoming more and more a concern a simple periodontal plastic surgical procedure can re-establish esthetic and balance to the patients affected by this condition.
