A Decade of the Socket-Shield Technique: A Step-by-Step Partial Extraction Therapy Protocol
Ten years have passed since Hürzeler and coworkers first introduced the socket-shield technique. Much has developed and evolved with regard to partial extraction therapy, a collective concept of utilizing the patient’s own tooth root to preserve the periodontium and peri-implant tissue. The specifications, steps, instrumentation, and procedures discussed in this article are the result of extensive experience in refining the socket-shield technique as we know it today. A repeatable, predictable protocol is requisite to providing tooth replacement in esthetic dentistry. Moreover, a standardized protocol provides a better framework for clinicians to report data relating to the technique with procedural consistency. This article aims to illustrate a reproducible, step-by-step protocol for the socket- shield technique at immediate implant placement and provisionalization for single-rooted teeth.

The Pontic-Shield: Partial Extraction Therapy for Implant Dentistry
Augmentive ridge preservation techniques aim to manage the postextraction ridge. The partial extraction of teeth may better preserve the ridge form by maintaining the bundle bone-periodontal tissues and preserve the ridge beneath dentures or fixed prostheses. The socket-shield technique entails preparing a tooth root section simultaneous to immediate implant placement and has demonstrated histologic and clinical results contributory to esthetic implant treatment. A retrospective 10-patient case series treating 14 partial extraction sites demonstrates how a modification of the socket-shield technique can successfully develop pontic sites and preserve the ridge.

Ridge Preservation with Modified “Socket-Shield” Technique: A Methodological Case Series
After tooth extraction, the alveolar bone undergoes a remodeling process, which leads to horizontal and vertical bone loss. These resorption processes complicate dental rehabilitation, particularly in connection with implants. Various methods of guided bone regeneration (GBR) have been described to retain the original dimension of the bone after extraction. Most procedures use filler materials and membranes to support the buccal plate and soft tissue, to stabilize the coagulum and to prevent epithelial ingrowth.

Sequencing of Periodontal Procedures and Orthodontic Treatment
Severe cases of periodontal disease often require periodontal surgery and realignment of teeth. Surgical techniques have been developed that attempt to minimize postsurgical gingival recession and compromise the interdental papillae. A case report is presented in which reversal and correction of a deteriorating maxillary frontal dentition were effectively achieved through combined use of periodontal and orthodontic principles. The treatment plan included the control of periodontal inflammation, restoration of lost attachment apparatus, realignment of anterior dentition, stabilization of occlusion, and minor periodontal plastic surgery. The anticipated loss of a maxillary lateral incisor was avoided. Restoration of a pleasant smile with nicely aligned teeth and esthetic gingival contours was achieved. The correct sequencing of the procedures involved was considered a key factor for the long-term esthetic outcome.

PETology and Complete Ridge Maintenance
For a long time it has been discussed about different ways to avoid dimensional changes at post extraction sockets. Through the philosophy of the Partial Extraction Therapies we will be able analyze and plan our cases in a different and unique way not only in the esthetic zone also in partial and full arch cases in a predictable and reproducible way.

Crown Lengthening in Comprehensive Esthetic Therapy: The Complete Surgical Video A to Z
In this complete surgical video, Dr. David Wong performs an esthetic crown lengthening procedure to address a "gummy smile" as part of comprehensive therapy and smile enhancement. Dr. Wong will outline the indications for crown lengthening surgery as opposed to orthognathic correction. The surgical video will demonstrate the complete crown lengthening surgery, including incision design, flap management and instrumentation. In addition, suturing and post-operative care will also be outlined in detail.

Advanced Immediate Implant Placement Strategies Including the Socket Shield (SS) Technique and its Complications
Immediate implant placement in the aesthetic zone has become a controversial topic with regards to the long term aesthetic demands that both the profession and our patients have placed on this treatment modality. Since the controversy broke a few years ago there have been a number of outstanding developments that have revolutionized the way we do immediate implant placement. Soft tissue augmentations using the tunnel technique as well as the socket whiled technique are 2 of these techniques which form the baseline of treatment in our clinic. This lecture will go through all the updated protocols of immediate implant placement supported by the literature as well as deal specifically with the finer details of the socket whiled technique including step by step photos and video of the technique. More importantly it will cover numerous complications that we have had to deal with over the last few years that we have been doing this technique.

Peri-Implantitis: Diagnosis, Etiology and Treatment
The dental implant therapy has evolved both in implant surface and design. The reason for the initial crestal bone loss has been proven and the risks of having a peri-implantitis have increased due to the early exposure of roughened surface. The prevalence of peri-implantitis is at a range of 28 to 56%. The role of dental professionals nowadays is to know how to interpret the signs of inflammation and establish the diagnosis of peri-implantitis, which is the most challenging, and be able to treat it properly since this is becoming a more needed therapy.

Partial Extraction Therapies: From Failure to Everyday Practice - Part 1 of 4
Tooth extraction is usually followed by the resorption of support tissues that may compromise the aesthetic and functional prognosis of the final rehabilitation. There have been numerous publications suggesting Partial Extraction Therapies contribute to the maintenance of the alveolar ridge dimensions. These techniques consist in intentionally preserving a buccal root fragment in order to avoid tearing the periodontal ligament and loosing the bundle bone, which leads to bone resorption. It has been reported that these are very sensitive techniques and may lead to some complications. In order to avoid these complications, the dental surgeon must know which cases can be treated with Partial Extraction Therapies and how to correctly perform them. In these presentations we will show what are the indications and contraindications, how to perform these techniques, the literature that sustains it, how can we benefit from digital technology to today's world, etc.
