Statements and Recommendations for Guided Bone Regeneration: Consensus Report of the Guided Bone Regeneration Symposium Held in Bologna, October 15 to 16, 2016.

Introduction: In the past 10 years, long-term studies have demonstrated that guided bone regeneration (GBR) is a successful and reliable technique for vertical and horizontal ridge augmentation, but strict and rigorous protocols must be adopted.

Material And Methods: Because no reports have yet been published with statements and clinical recommendations for GBR, a closed meeting of all authors was organized to discuss this matter during a GBR symposium held in Bologna (Italy) in October 2016. The authors focused on the findings of systematic and narrative reviews, prepared before the meeting, covering aspects of the clinical management of GBR techniques.

Periodontal response to two different subgingival restorative margin designs: a 12-month randomized clinical trial.

Objectives: Subgingival margin placement is sometimes required due to different reasons and is often associated with adverse periodontal reactions. The purpose of this study was to determine if a single restoration with subgingival margin on a tooth, in the maxillary anterior zone, would affect its periodontal soft tissue parameters, and whether or not a deep chamfer preparation has a different influence in the periodontium when compared to a feather edge preparation.

Material And Methods: Plaque and gingival indexes, periodontal probing depth, bleeding on probing, and patient's biotype were registered.

Significance of crown shape in the replacement of a central incisor with a single implant-supported crown.

Objective: When utilizing a single implant-supported crown to replace a central incisor, understanding the final shape of the implant restoration is an important factor to help achieve a successful esthetic outcome. In today's dentistry, tooth shape is a critical factor when dental implant prostheses are considered in the esthetic zone. The major esthetic goal for this type of restoration is to achieve the closest possible symmetry with the adjacent tooth, both at the soft and at the hard tissue levels.

A technique for immediate occlusal implant loading of a completely edentulous mandible: a clinical report.

The protocols described are designed for immediate implant loading of the completely edentulous mandible and to provide the patient with a prosthesis that incorporates structural durability and esthetics in a time efficient manner. Incorporating appropriate diagnostic and surgical procedures, this clinical report describes the use of custom-fabricated transparent devices that help the clinician identify implant position, thereby reducing the procedural time and improving the structural durability and esthetics of the immediate prosthesis.

A prospective, multicenter, randomized-controlled 5-year study of hybrid and fully etched implants for the incidence of peri-implantitis.

Background: The dual acid-etched (DAE) implant was commercially introduced in 1996 with a hybrid design incorporating a machined surface in the coronal region from approximately the third thread to the seating surface. This design was intended to reduce the risks of peri-implantitis and other related soft tissue complications that were reported for implants with surface roughness in the coronal region. The objective of this prospective, randomized-controlled clinical trial was to determine the incidence of peri-implantitis for a fully etched implant with the DAE surface extending to the implant platform.
