简要总结
The goal of this clinical trial is to evaluate the influence of Facial Scan (FS) and cone beam computed tomography (CBCT) in the prosthodontic treatment planning in patients who require rehabilitation with a single crown.
After collecting the patients, at the first appointment, data collection will be carried out, including: an intraoral scan (digital impressions), intraoral and extraoral photographs, CBCT, and facial scanning.
At the following appointment, a mock-up will be performed. The purpose of the mock-up is to preview the expected smile outcome before beginning the oral rehabilitation treatment.
After each mock-up, patients will be asked to complete a questionnaire designed to evaluate their self-perception of comfort and aesthetics.
Additionally, after each mock-up, the clinician will assess occlusal contacts (the bite) and record the time required for adjustments to achieve a comfortable occlusion for the patient.
The main questions it aims to answer are:
- How does the patient perceive comfort and aesthetics during the rehabilitation process?
- What is the influence of using a virtual articulator on diagnostic waxing accuracy?
- How does integrating facial scanning (FS) and cone-beam computed tomography (CBCT) affect current digital workflows involving a virtual articulator?
- What impact does the programming of the virtual articulator have on treatment planning outcomes?
详细描述
The goal of this clinical trial is to evaluate the influence of Facial Scan (FS) and cone beam computed tomography (CBCT) in the prosthodontic treatment planning in patients who require rehabilitation with a single crown, with aims:
i) assessing patient's comfort and aesthetics self-perception; ii) evaluate the influence of a virtual articulator in a diagnostic waxing; iii) evaluate the influence of implementation of FS and CBCT to the current digital procedure with a virtual articulator; iv) evaluate the influence of programming the virtual articulator.
Data collection will be carried out in participants, including: an intraoral scan (digital impressions), intraoral and extraoral photographs (DPhotos), CBCT, and facial scan.
In a CAD/CAM software, we will integrate IOS, CBCT, and FS data into the virtual environment, and it will be possible the articulation of virtual models.
The digital wax-up for the preparation of the crown will be designed by the prosthodontist and then adjusted based on the occlusion obtained in each of the groups.

研究组 & 干预措施
Static occlusion
Use IOS + DPhotos - Set up the models and do a diagnostic waxing done only with static occlusion, without a virtual articulator (as the laboratories commonly do).
干预措施: Try-in of one crown test with a digital wax-up (per group) (Procedure)
Virtual articulator (standard values)
Use IOS + DPhotos - Set up the models do a diagnostic waxing in the virtual articulator arbitrarily (without CBCT and FS) - with the program's default and standard values.
干预措施: Try-in of one crown test with a digital wax-up (per group) (Procedure)
Virtual articulator with CBCT and FS (standard values)
Use IOS + DPhotos + CBCT + FS - Set up the models and do a diagnostic waxing in the virtual articulator (with CBCT and FS) - with the program's default and standard values.
干预措施: Try-in of one crown test with a digital wax-up (per group) (Procedure)
Programmed virtual articulator
Use IOS + DPhotos + CBCT + FS - Set up the models and do a diagnostic waxing in the virtual articulator (with CBCT and FS) - with the articulator programmed for the patient - through dynamic scans.
干预措施: Try-in of one crown test with a digital wax-up (per group) (Procedure)
结局指标
主要结局
Differences before and after occlusal adjustments
时间窗: From enrollment to the end of treatment (8 weeks)
The primary outcome is the volumetric difference (in micrometers) before and after occlusal adjustments, in each group.
次要结局
- Patients's aesthetics and comfort self-perception(From enrollment to the end of treatment (8 weeks))
