The aim of this paper was to identify factors significant to the use of single-stage dental implants in the aesthetic zone and discuss treatment considerations related to them. In view of available literature and clinical experiences, treatment outcomes associated with the use of single-stage Straumann implants (Institut Straumann AG, Waldenburg, Switzerland) in the aesethetic zone can be considered positive and predictable.
The use of dental implants to assist in the treatment of partial and complete edentulism is well documented. Most of the implant literature, however, reports results associated with implant survival and success when there has been adherence to rigid placement and loading protocols. Conventionally, these protocols call for the undisturbed healing of the implant-3 months in the mandible and 4 to 6 months in the maxilla. This article evaluates the literature and develops protocols for clinical procedures for the early or immediate restoration or loading of dental implants. Criteria are established for defining immediate loading, immediate restoration, early loading, and early restoration as compared to conventional protocols. The review assesses factors that influence accelerated loading and restoration decisions, including bone quality and quantity, implant design, splinting of implants, and prosthetic design. Conclusions and recommendations are made based on the experience of the consensus group charged with considering these procedures and on the current literature published on these protocols.

The success rate of a restored, endodontically treated tooth is of interest to the dentist and patient when planning the treatment of a tooth requiring endodontics. The reported success rate for nonsurgical root canal treatment is varied within the dental literature. An alternative measure is tooth survival. This will include other factors related to endodontic treatment that result in poorer tooth survival. An understanding of the survival of endodontically treated teeth compared with alternative treatment modalities, such as dental implants, will provide for a more informed treatment plan.
