Summary:

In the esthetic zone of the maxilla a proper emergence profile, predicated on healthy normal marginal gingival tissues with intact interdental papillae, is critical to achieving esthetically pleasing traditional fixed and implant supported restorations. Adequate soft tissue morphology, however, is dependent upon a stable, adequate volume of underlying bone capable of serving as a viable, biologic foundation for overlying soft tissues. Without the harmony afforded by a proper balance of underlying bone and overlying soft tissue, esthetic restorations are not possible, especially in the anterior maxilla. Frequently, however,alveolar bone loss disturbs that critical balance,resulting in marginal tissue distortion, recession and loss of esthetically crucial interdental papillae. Bone loss is common in the esthetic zone and can result from multiple precipitating events, the most common following tooth extraction. Multiple studies have documented predictable 3 mm to 4 mm of buccolingual and apicocoronal ridge resorption within 6 months after removal of maxillary anterior teeth. If left untreated up to 50% buccolingual bone loss will occur after one year post tooth removal in the critical esthetic zone.

Physical And Chemical Properties Of Commercially Available Mineralized Bone Allograft

Physical And Chemical Properties Of Commercially Available Mineralized Bone Allograft
Bone graft materials are critical to the success of dental implants when there is a need to increase the volume of bone in a defect. The surface properties of these graft materials will have a profound impact on the outcome of the graft procedure. The clinician has many choices of bone graft substitutes when augmenting bony deficits. Allograft bone is the most widely used class of bone graft substitutes. Within this class there are a number of different bone allografts, which are manufactured utilizing widely varying processing techniques. There also appears to be a wide range of results in the published literature across the spectrum of different bone allografts. This in-vitro study evaluated chemical and surface properties of five different commercially available mineralized bone allografts.

Modern Implant Dentistry: Rules of Engagement in the Esthetic Zone - Part 1 of 2
This presentation will focus on the interdisciplinary relationship of the restorative dentist, periodontist and orthodontist to reconstruct the soft tissue foundation for all of these restorative options in anterior tooth replacement. The diagnosis of deficiencies as well as the varied treatment options will be discussed in detail. This includes periodontal crown lengthening, esthetic periodontal plastic soft tissue grafting procedures as well as prescription adjunctive orthodontic tooth movement to manipulate the soft tissue foundation prior to or subsequent with the restorative options of implants, bridges, or pontic replacement.

S.M.A.R.T. Minimally Invasive Bone Grafting
Introduction to the S.M.A.R.T. TM Minimally Invasive Bone Grafting Technique is a novel minimally invasive bone grafting technique developed by Dr. Ernesto Lee. It provides superior outcomes with less pain, less swelling and fewer complications than traditional bone grafting procedures. Only a small incision is required, with no flap elevation, no tenting screws and no membranes. Complex, high risk scenarios can now be treated with minimal risk of complications. The S.M.A.R.T. TM method represents a disruptive technology that will dramatically impact the future of bone grafting

The Dual Zone Approach to Tooth Replacement in the Esthetic Zone
Improvements in implant designs have helped advance successful immediate anterior implant placement into fresh extraction sockets. Clinical techniques described in this presentation will enable practitioners to achieve predictable esthetic success using a method that limits the amount of buccal contour change of the extraction site ridge and potentially enhances the thickness of the peri-implant soft tissues coronal to the implant-abutment interface. This approach involves atraumatic tooth removal without flap elevation, and placing a bone graft into the residual gap around an immediate fresh-socket anterior implant with a screw-retained provisional restoration acting as a prosthetic socket seal device. Long term follow up and evidence from scientific literature to support this concept will be described.

“The Full Arch Patient”; A Fully Digital Affair
Guided Surgery (GS) is a concept where you are guided by the rehabilitation needs of your patient to perform the implant surgery procedure based on all the info that we process via planning software that are loaded with digital files coming from intra-oral scanning (IOS) and cone beam computed tomography (CBCT). After planning the case, we print a surgical guide or stent to perform the surgery, this technique allows us to do it flap or flapless in a complete secure environment, quicker and more precise if we compare to "freehand" surgery. However, we have to be careful because not all the systems are the same; those who use scoops as reductors are less precise than the "scoopless", no matter which system we use we have to be clear to understand that all the classic concepts of osseointegration are not erased by guided surgery, especially bone physiology.

Bone Augmentation & Vascular Enhancement Concepts: It’s Time to Make it Simple!
The purpose of this presentation is to make the participant think biology first and not mechanic first. A biological thinking will dramatically simplify vertical and/or horizontal bone augmentation procedures. We will also be introducing a new approach for the simplification of soft tissue handling: the Soft Brushing Technique, that will allow the coronal advancement of both buccal and lingual flaps, but also the palatal flap without the need for periosteal releasing incisions.
