The Root Submergence Technique at Single Tooth Sites to Short-Span Edentulous Sites: A Step-By-Step Partial Extraction Therapy Protocol
Submerging roots for ridge preservation was the earliest partial extraction therapy and has been described since the 1970s. Despite the approximately 47 animal and human studies published since, an updated and contemporary step-by-step protocol has not yet been provided. This technique report describes in detail how to manage submerged roots at single tooth sites and at short-span edentulous areas.

Fibrinogen-Induced Regeneration Sealing Technique (F.I.R.S.T.). An Improvement and Modification of Traditional GBR: A Report of Two Cases
Guided bone regeneration is a technique widely known, clinicians know very well indications and limitations of this technique. One of the principles to achieve bone augmentation and formation resides in the stability of the blood clot forming under a barrier membrane. The technique proposed in this article has the goal of providing stabilization to the bone graft by adding fibrin sealant (FS) to the bone graft and also using the fibrin sealant to attach a bone membrane (cortical lamina) to the recipient site. This simple modification of the technique of guided bone regeneration is presented in two successful cases.

Buccal Sliding Palatal Pedicle Flap Technique for Wound Closure After Ridge Augmentation
One standard approach for wound closure after ridge augmentation is coronal flap advancement. Coronal flap advancement results in displacement of the mucogingival junction and reduction of the vestibulum. In the maxilla, a buccal sliding palatal flap can be applied for primary wound closure after ridge augmentation. The dissected part of the palatal connective tissue is left exposed, thus eliminating or reducing the amount of the coronal flap advancement respectively and increasing the amount of keratinized gingiva. In combination with guided soft tissue augmentation, this flap design enables a three-dimensional peri-implant soft tissue augmentation.

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.

Recombinant Human Platelet– Derived Growth Factor: A Systematic Review of Clinical Findings in Oral Regenerative Procedures
The use of recombinant human plateletderived growth factor–BB (rhPDGF) has received Food and Drug Administration approval for the treatment of periodontal and orthopedic bone defects and dermal wound healing. Many studies have investigated its regenerative potential in a variety of other oral clinical indications. The aim of this systematic review was to assess the efficacy, safety, and clinical benefit of recombinant human plateletderived growth factor (rhPDGF) use for alveolar bone and/or soft tissue regeneration. Based on the clinical evidence, rhPDGF is safe and provides clinical benefits when used in combination with bone allografts, xenograft, or β-TCP for the treatment of intrabony and furcation periodontal defects and gingival recession or when used with allografts or xenograft for GBR and ARP.
