Purpose. This observational study introduces a novel digital technique for analyzing the inclination of the tooth emergence profile and the distance between the bone crest and the cementoenamel junction (CEJ), essential in prosthetic dentistry. Material and methods. The study used cone-beam computed tomography (CBCT) scans from 24 patients, analyzing 57 teeth for emergence profile inclination and 206 teeth for the bone crest-CEJ distance. Digital measures were taken using an implant planning software. Results. The emergence profile] angle varies according to the tooth anatomy. Results indicated an increase in emergence profile angle from an average value of 13° to 19° when simulating prosthetic chamfer preparation, highlighting the importance of maintaining the natural tooth anatomy in restorative procedures. The average distances between bone crest and CEJ were 2.43 ± 1.08 mm on the buccal side, 1.96 ± 0.88 mm on the palatal side, 1.88 ± 1.05 mm on the mesial side, and 1.97 ± 0.92 mm on the distal side. Discrepancies in bone crest heights, particularly at the vestibular reference point, were found, which could affect periodontal health. Conclusion. The research provides a foundation for future studies to refine soft tissue management techniques in dental practice. These findings underscore the needing for a deeper understanding of supracrestal tissues in prosthetic rehabilitation, aiming to enhance the design of anatomical implant abutments and improve patient outcomes.
