Provide a 6 pages analysis while answering the following question: The Role of CAD-CAM Technology in Implant-Retained Prosthodontics. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. Detection of changes in the distal alveolar residual ridges of the implants that are contained by the edentulous mandible is critical when implant-retained overdentures are used. This is an important area of clinical and operative dentistry since research and experience have shown that these increase satisfaction and really improve the quality life of the individuals who are edentulous (Blum and McCord, 2004). Naert et al. (2004) have indicated that these are preferred in terms of speech, stability, and function. These usually utilize the principles of CAD-CAM technologies, which employ computer-assisted design and computer-assisted machining. These have been reported to have received considerable research and clinical interest from the modern dental practice. The idea of using these technologies to produce lifelike restoration of natural dentition with consistent esthetic outputs (Naert et al., 2004). Consequently, these techniques have been welcome by the orthodontists and the patients. The CAD/CAM system may be used in different steps of implant retained dentistry such as fabrication of crowns, bridges, and telescope dentures (Sun et al., 2006).

From the clinical and technological standpoints, the passivity of fit of the implant prosthesis is the most important consideration. This is an important parameter for intraoral osseointegrated and functional fixtures. Traditionally, these had been accomplished with clinical procedures and methods utilized in laboratory fabrication in both fixed and removable partial dentures used in prosthodontics. The impression making, master cast, resin verification, and other stages such as investing, casting, veneering, and finishing all potentially may lead to distortion and hence prevent passivity of fit (Raigrodski, 2003). The techniques of optical digitalization and use of CAD-CAM technologies may bypass these stages, and as alternative strategies, they may really achieve the intended passivity of fit. If the goal is to achieve clinical longevity of the prosthesis, CAD-CAM may confer a most minimum level of distortion and acceptable level of associated stress in comparison to the other techniques. There is a growing body of literature that deals with the accuracy of these procedures with the utilization of CAD-CAM technologies (Tan, 1995).
