Evaluación con scanner intraoral de la continuidad de la línea terminal de preparaciones para carillas en Clínica UCSG “semestre A-2024.”

Abstract

Objective: The objective of the present study was to determine the continuity of the finishing line of veneer preparations at the UCSG clinic during the A- 2024 semester. Materials and methods: An intraoral scanner was used in 15 patients who attended the UCSG dentistry clinic. The thickness of the finishing line of the mesial, vestibular, and distal edges was measured and if the use of dental bur influenced the obtained results. The data were analyzed using the TSTUDENT test in the R commander statistical program. Results: Significant differences were observed when comparing the measurements of the mesial face with the vestibular face (t=4,3336, gl= 24,255, p=0,0002217) and the distal face (t = 3,6318, gl= 24,861, p-value = 0,001275). When comparing the continuity of the 3 faces, more than 86,67% of the measurements were discontinuous. The operator's gender and the type of bur used did not show significant differences in the measurements of the finishing line (p>0,05). Conclusion: Continuity in the thickness of the midline of the finishing line in the preparation was not observed. Neither the operator's gender nor the type of burs influenced the continuity of the finishing line preparation for veneers. To improve continuity, it is recommended that students make more veneer preparations in dental typondont.
