Introduction: Loss of teeth with aging is one of the most prevalent issues that has been addressed by many dental practitioners. However, the most challenging scenario occurs if the patient is early-to- middle-aged, and despite the major periodontal/functional loss the primary concern is to attain beau ideal. Hence, demand to regain ideal smile and being defiant to stay edentulous throughout the treatment lead dentists to opt for immediate protocols. Immediate loading of provisional prostheses (PPs) after computer-guided implant surgery with prototyped surgical guides (SGs) is an effective method for realizing optimum function and desired esthetic.

Case Description: A 44-year-old woman presented compromised esthetic, advanced mobility of mandibular incisors and progressive pain in chewing. Intraoral examination revealed increased overjet, polydiastema between maxillary incisors, high maxillary lip-line, periapical lesions/mobility in molar teeth. Impression could not be taken using irreversible hydrocolloids due to prominent mobility of incisors; therefore, diagnostic models were obtained via Trios 4®. Overall study on X-rays and diagnostic models concluded that the patient was having severe chronic periodontitis with insufficient oral hygiene and aggressive bone resorption.

CoDiagnostiX® software was preferred to merge DICOM and .STL formats, as well as planning of implant locations, PPs and SGs. Following surgery, scan bodies were placed and scanned to build up PEEK PPs which were delivered the day after surgery. Controls were done on the next week, 1-month and 3- month periods.

Discussion: Through the advancements in digital dentistry, full-mouth rehabilitations can no longer last at a dragging pace which grants them high precedency over traditional methods. Fabricating SGs and planning PPs beforehand let practitioners be more confident about both surgical and prosthodontic outcomes. Likewise, the patients undergo much more comfortable processes due to increased perception of the immediate aftermath. Completing the groundwork on CoDiagnostiX® environment hereby maximize accuracy and time-efficiency which eventually satisfies both parties.
