Complete denture processing errors – A proposed classification system and its incidence in Preclinical Prosthodontics training of second year undergraduate dental students

The Journal of Indian Prosthodontic Society | Volume 20 | Supplement 1 | December 2020 S13 Methodology: Extracted human premolars were prepared and prepared castings were luted with different luting agents. Specimens were subjected to piezoelectric ultrasonic procedures with different frequencies and evaluated the margin interface with a surface profilometer and scanning electron microscope. Result: The specimens luted with glass ionomer cement has shown a lesser marginal discrepancy in both low and high frequencies than the samples luted with self-adhesive resin in low and high frequencies at the margins interface. Conclusion: The specimens which have subjected to low frequency shown less discrepancy than the specimens subjected to high frequency irrespective of the luting agent. Samples luted with glass ionomer cement measured discrepancy of 2μm between low and high frequencies, whereas self-adhesive resin measured discrepancy of 7μm.

Dental College & Hospital, Bagalkot Introduction: The complete denture processing error may ruin the efforts of a dentist, student or the technician. The aim of the present study was to propose and evaluate a new classification system for complete denture processing error and to access its incidence in the complete denture processed by the 2nd year undergraduate students of PMNM dental college and hospital Bagalkot. Methodology: 100 second year Pre-clinical prosthetics undergraduate dental students with their approved teeth arrangement ready for processing were included in the study. Each step of the processing was observed and assessment of processing error was done. Result: In the present study Out of 200 unites of dentures (100 maxillary and 100 mandibular), stage 1 processing errors were most common in mandibular dentures (10% in mandibular and 3% in maxillary cast), stage 2 processing errors were most common in maxillary denture (15% in maxillary 12% in mandibular), stage 3 processing errors were most common in mandibular denture (12% in mandibular and 8% in maxillary). Conclusion: This study encourages further laboratory studies for validation and reliability evaluation of proposed new classification system and its incidence in clinical practice.
