Three-Dimensional Bone and Soft Tissue Requirements for Optimizing Esthetic Results in Compromised Cases with Multiple Implants
In this article, the concepts behind achieving esthetic and functional implant restorations and the necessary three-dimensional peri-implant hard and soft tissue management required to realize these goals are discussed.

Advantages of the Root Submergence Technique for Pontic Site Development in Esthetic Implant Therapy
This article suggests a strategy to provide a more predictable protocol for esthetic implant treatment for multiple- tooth defects using the root submergence technique (RST). The RST maintains the natural attachment apparatus of the tooth in the pontic site, which in turn allows for complete preservation of the alveolar bone frame and assists in the creation of an esthetic result in adjacent multipletooth- replacement cases.

Timing, Positioning, & Sequential Staging in Esthetic Implant Therapy
Many articles address the predictability of immediate implant placement into extraction sockets; however, there are only a few reports that mention the indications and limitations of this technique. The aim of this article is to re-examine specific indications for immediate implant placement and to clarify the timing or “fourth dimension” relative to extraction and implant placement. The expanded concept of four-dimensional implant treatment planning involves the new axis of time, which must be…
