The influence of provisional restoration on the adjustment of final prosthetic devices in the fabrication of a crown-bridge denture for a missing mandibular First Molar Using Digital Impressions.

JRCT ID: jRCT1032220393

Registered date:19/10/2022

Basic Information

• Recruitment status: Pending
• Health condition(s) or Problem(s) studied: Tooth Loss
• Date of first enrollment: 19/10/2022
• Target sample size: 10
• Study type: Interventional
• Intervention(s): Patients scheduled for prosthetic treatment with bridges for missing mandibular first molars will have their intermaxillary relationship recorded using an intraoral scanner in Prov+ and Prov-, and the final prosthetic device will be fabricated from the data of each.

Outcome(s)

• Primary Outcome: Three-dimensional quantification of the difference in the amount of adjustment between the final prosthetic device fabricated based on the data recorded for the intermaxillary relationship in Prov+ and the final prosthetic device fabricated based on the data recorded for the intermaxillary relationship in Prov-.
• Secondary Outcome: Quantify the difference in distance between the opposing and abutment dentition in the three-dimensional morphological data of the maxillary and maxillary dentition recorded intermaxillary relationship with Prov+ and the data recorded intermaxillary relationship with Prov-.
