“…40 In some studies the authors express the opinion that the results were not more favorable for the CAD/CAM groups due to the inaccuracies of impression making and cast fabrications, and found the intraoral impression devices as a very promising approach. 41,16 LEGENDS Fig.1.

“…3 Several implant impression studies have reported that working casts fail to exactly replicate the original situation. 16,17 The introduction of computer-aided design/Computer aided manufacturing (CAD/CAM) technology in dentistry has resulted in a more accurate manufacturing of prosthetic frameworks, greater accuracy of dental restorations and implant supported prosthesis in particular 18 .…”

PURPOSE: To obtain an accurate CAD/CAM metal framework over 6 implants using a Chairside Intraoral Scanner based on the principle of active (optical) wavefront sampling. MATERIAL AND METHODS: Six prototype cylindrical scan bodies screwed in the implants were used to obtain an intraoral digital impression. A conventional resin tooth try-in was fabricated and digitized with an extraoral scanner, and this dataset was merged to the digital data obtained from the intraoral impression to calculate the best framework design with advanced CAD software. The framework was fabricated with a 5-axis computer numerical control milling unit. Three clinical tests (saliva intrusion, Sheffield test, and screw resistance test) were performed to assess the fit of the framework. RESULTS: Under 3 clinical tests, an accurate fit was observed. CONCLUSION: The case presented in this report proposes a new clinical protocol for obtaining accurate digital impressions of multiple implants. Purpose: To test clinically the possibility to obtain an accurate CAD/CAM implant framework over 6 implants

“…Although practical evidence is limited, theoretically these successive unions of clouds of points could cause an accumulation of error. For this reason, reliability diminishes progressively according to the increasing number of implants analyzed (25). But in contrast with intraoral video and photographic scanners, photogrammetry generates director vectors of the exact position of the implants in relation to one another.…”

Aim: To describe a technique for registering the positions of multiple dental implants using a system based on photogrammetry. A case is presented in which a prosthetic treatment was performed using this technique. Study Design: Three Euroteknika® dental implants were placed to rehabilitate a 55-year-old male patient with right posterior maxillary edentulism. Three months later, the positions of the implants were registered using a photogrammetry-based stereo-camera (PICcamera®). After processing patient and implant data, special abutments (PICabutment®) were screwed onto each implant. The PICcamera® was then used to capture images of the implant positions, automatically taking 150 images in less than 60 seconds. From this information a file was obtained describing the relative positions – angles and distances – of each implant in vector form. Information regarding the soft tissues was obtained from an alginate impression that was cast in plaster and scanned. A Cr-Co structure was obtained using CAD/CAM, and its passive fit was verified in the patient’s mouth using the Sheffield test and the screw resistance test. Results and Conclusions: Twelve months after loading, peri-implant tissues were healthy and no marginal bone loss was observed. The clinical application of this new system using photogrammetry to record the position of multiple dental implants facilitated the rehabilitation of a patient with posterior maxillary edentulism by means of a prosthesis with optimal fit. The prosthetic process was accurate, fast, simple to apply and comfortable for the patient. Key words:Dental implants, photogrammetry, dental impression technique, CAD/CAM.
