Abstract

Implant dentistry provides unique and predictable methods for the replacement of missing teeth. The need for provisionalization of implant-supported prostheses is increasing. Interim denture is a prosthesis designed to enhance esthetic, provide stability and function for a limited of time and should be replaced by definitive prosthesis after a period of time. A challenge exists for prosthodontist in treatment planning and providing treatment for the patient before surgical phases. The interim restoration is an important diagnostic tool and a key factor for patient, dentist, technician and surgeon communication. Immediate provisionalization of implants at the time of placement can provide a tooth-like restoration for the patient. In addition, interim restorations are frequently used for immediate or early occlusal loading of implants, for soft tissue management to obtain a natural emergence profile and during the fabrication period of the definitive prostheses. Achieving esthetics in the anterior maxilla depends on natural looking teeth enveloped by normal soft tissue. Soft tissue will recede if not supported by alveolar bone, tooth structures or restorations, resulting in an esthetic failure. Interim restorations can be either fixed or removable but certain key principles should be followed to prevent deleterious effects on the tissue in the edentulous space. Although implant-supported provisional restorations are usually fabricated in the laboratory, there are some clinical situations that demand the direct fabrication of provisional restorations, especially when there is a high esthetic demand. Various techniques to make implant-supported interim restorations have been described in the literature. This chapter includes indications and the types of interim restorations in implant dentistry. The interim restorative materials and different techniques for making interim restorations will also be discussed. © 2010 Nova Science Publishers, Inc.
