Summary:
This study aimed to evaluate the influence of labial alveolar bone thickness and the corresponding vertical bone loss on postoperative gingival recessions around anterior maxillary dental implants. Using cone beam computed tomography (CBCT) scanning, the temporal changes of three-dimensional images of alveolar bone were monitored to determine hard and soft tissue outcomes of two different implant placement techniques: delayed two-stage and immediate placement. Furthermore, for the delayed two-stage placement, guided bone regeneration was applied using either nonresorbable or resorbable membranes combined with anorganic bovine bone matrix. The comparative results suggested that gingival recessions were significantly lower in delayed two-stage placement, especially when using a nonresorbable membrane, compared to immediate placement, and labial bone thickness, measured by CBCT, offered an effectual indicator to assess gingival recession in the anterior region.

Osseointegrated Titanium Implants for Maxillofacial Protraction in Monkeys
Titanium implants were placed surgically into the maxillary, zygomatic, frontal, and occipital bones of four pigtail monkeys. After a 4-month healing period, the implants were exposed and abutments were placed. Extraoral traction appliances were then attached to the abutments. The cranial implants were used to support the framework of the traction appliance; those in the facial bones were used to attach springs that delivered a protraction force. The application of force varied among animals. In animal…

Restoring Facial Aesthetics and Function with Implant Overdentures
Implant supported overdentures are
fast becoming the choice of treatment for
edentulous patients as they provide various
advantages over the conventional dentures;
most importantly they are a reliable and
simple solution to denture retention and
stability problems. This article discusses
aesthetics and function provided with
implant borne Overdentures in Maxillary
and Mandibular arches.

Cortical Tenting Grafting Technique in the Severely Atrophic Alveolar Ridge for Implant Site Preparation
Tenting of the periosteum and soft tissue matrix using a
cortical bone block maintains space and minimizes resorption of the particulate allograft volume. In addition,bridging the cortical blocks with particulate bone avoids unaesthetic ridge defects between cortical block grafts in larger ridge defects. The result was
a more uniform and esthetic alveolar ridge, capable of maintaining an implant-supported prosthesis. The
technique offers predictable functional
and esthetic reconstruction of large volume defects without extensive amounts of autogenous bone. This of-
fers a superior functional and esthetic result than with either cortical or particulate grafting alone.

Negative Factors for Soft & Hard Tissue Maintenance
Maintaining the bone is the most difficult challenge in implantology (bone grafted or native bone around implants). If a tissue want to live long, it has to follow 2 conditions: The first condition is to organize a full blood supply.. However, it’s not enough.
The solution for the long term stability is to try to organize the stability of the blood supply.. by the respect of several biologic conditions. Almost of these conditions are explained in this lecture.
We introduce here the new concept to avoid the reduction of blood supply by the periosteal incision: the soft brushing technique is the first technique which allows a very large increase of the flap without any incision: the flap closure without tension but without any incision.

Digital Dentistry in the Management of Simple and Complex Cases: The Digital Intra-Scanner - Part 2
The advent of new technologies has enabled the utilization of new materials and equipment that facilitate the production of restorations with an accuracy that has, up to now, been difficult to obtain reliably. This lecture utilizes patient presentations to help analyze and highlight new systematic clinical protocols that have been developed to optimize the evolving knowledge in digital dentistry and materials.
These protocols have allowed us to modify work flow and operational techniques to shorten lead times, while maintaining optimal accuracy. Advantages and disadvantages of the methods outlined will be evaluated and analyzed on the basis of existing literature and personal experience.

Implant Esthetics: Recognizing Pitfalls and How to Avoid Problems
In this Webinar on Implant Esthetics, Dr Stanley describes the "No Half Smiles" philosophy that he practices. An emphasis is placed on both the clinical and technical requirements necessary for delivering consistent successful esthetic results in everyday practice. In addition, several techniques are demonstrated to make patient management through this process more efficient. As Dr. Stanley states" the challenges of getting it right are many but avoiding complications is vital to the success of our daily practice.
