One of the crucial factors in the success of guided bone regeneration (GBR) procedures is the correct management of the soft tissues. This allows for stable primary wound closure without tension, which can result in premature exposure of the augmentation area, jeopardizing the final outcome. The use of vertical and periosteal incisions to passivate buccal and lingual flaps in the posterior mandible is often limited by anatomical factors. This paper reports on a series of 69 consecutive cases introducing a novel surgical technique to release and advance the lingual flap coronally in a safe and predictable manner.

Reductions in peri-implant bone height have been acknowledged as a normal consequence of implant therapy. Various restorative factors contribute to this phenomenon. One is repeated abutment retightening, which causes a mechanical disruption at the implant-abutment interface, leading to soft tissue recession. Several investigators proposed placement of the definitive abutment after implant placement as a solution to the problem. The definitive use of an intermediate abutment after implant placement seems to positively affect the soft tissue response. This article aims to present a prosthetic sequence for achieving peri-implant tissue stability in the esthetic zone.

The aim of the present case series was to evaluate the short- and long-term (3 years) soft tissue stability of a surgical technique combining transmucosal implant placement with submarginal connective tissue graft (CTG) in an area of shallow buccal bone dehiscence.
Abutment-Supported Papilla: A Combined Surgical and Prosthetic Approach to Papilla Reformation
LIT-064
Dr. Istvan Urban
Restoration of lost interdental papilla remains one of the most challenging goals for clinicians. When a single tooth is replaced with an implant, the papilla between the tooth and the implant can often be maintained or predictably restructured as long as the periodontal attachment and bone of the adjacent tooth is preserved. However, if the periodontal support is compromised on the neighboring natural tooth, the papilla will often be deficient or missing. This article presents a multidisciplinary treatment approach to regenerate the interdental papilla between an implant and a periodontically compromised tooth using surgical procedures and a customized abutment. Specifically, an abutment with modified subgingival contours is used to enhance support of the surgically reformed papilla.

An approach to biomimetics: The natural CAD/CAM restoration: A clinical report
LIT-060
Dr. Pascal Magne
Those in the dental field have always pursued the perfect dental material for the treatment of compromised teeth. Gold, amalgam, composite resin, glass ionomer, and porcelain have been used. Tooth-like restorative materials (composite resin and porcelain) combined with an effective hard tissue bond have met the growing demand for esthetic or metal-free restorations in the past 15 to 20 years. However, none of those materials can fully mimic the unique properties of dentin (compliance and crack-stopping behavior) and enamel (wear resistance, function). The aim of this article is to report the restoration of an extensively damaged tooth with a natural restoration obtained by milling an extracted third molar tooth with a computer-aided design and computer-aided manufacturing (CAD/CAM) system. The main benefit of this novel technique is the replacement of lost tissues by actual enamel and dentin, with the potential to recover mechanical, esthetic, and biologic properties. The indication for extracting third molars and premolars because of impaction or for orthodontic reasons makes these posterior teeth readily available. The innovation of the method presented here is the optimal use of the extracted tooth substrate thanks to its positioning technique in the CAD/CAM milling chamber.
IDS: Immediate Dentin Sealing (IDS) for Tooth Preparations

Dr. Pascal Magne
There is a strong body of evidence to support applying an adhesive resin coating to the freshly cut dentin according to the manufacturer’s instructions1-9 when a significant area of dentin has been exposed during tooth preparation for indirect restorations, such as inlays, onlays, veneers, and even crowns. Freshly cut and clean dentin is ideal for dentin bonding.11 IDS enables the pre-polymerization of the dentin bonding agent, resulting in improved bond strength...
Immediate dentin sealing supports delayed restoration placement
LIT-058
Dr. Pascal Magne
Statement of problem: Immediate dentin sealing (IDS) is a new approach in indirect restorations. Dentin is sealed immediately following tooth preparation, prior to impression making. It is not known whether it is still possible to obtain an efficient bond between the resin-coated dentin and the restoration after 2 to 4 months of placement of provisional restorations. Purpose: The purpose of this study was to determine if there were differences in microtensile bond strength to human dentin using the IDS technique when comparing 2, 7, and 12 weeks of delay until restoration placement, using 2 different dentin bonding agents (DBAs). Previously published preliminary IDS data were included for comparison.
