Dental Model Analysis Section
Q: What is required during the preparation of image data for the dental model analysis?
A: The user must add the ruler with a scale of at least 0.5 millimeter resolution or better to facilitate the normalization by adding the relative distance. Moreover, the upper and lower dental model must be in the middle area of the photograph to ensure proper analysis, or it will create complications during the orthodontic movement simulation of individual teeth while the background of the dental model image must be a single color including black to ease the segmentation process.
Q: What type of dental model analysis can be applied in CephSmile?
A: The types of dental model analysis to be applied in CephSmile consist of:
- Dental Arch Parameters
- Dental Space Analysis
- Bolton Analysis
Q: How do Dental Arch Parameters relate to the dental arch?
A: The Anterior Dental Width, Posterior Dental Width, and the Anterior Dental Depth are used to check whether the dental curves are at the proper form.
Q: How does relate to the dental width measurements of individual teeth?
A: Dental Space Analysis can show whether the jaw has enough space for the teeth by comparing the sum of dental widths from individual teeth (the required dental space) with the segmented dental curve lengths (the available dental space) applied on the ten anterior teeth that can be readjusted by the arch wires. When the available dental space is less than the required dental space, dentists can correct this problem by filing or extracting teeth to make more space available.
Q: How does Bolton Ratio Analysis relate to the dental width measurements of individual teeth?
A: Bolton Ratio Analysis is the way to check the relationship between the sum of maxillary teeth widths and the sum of mandibular teeth widths to calculate the ideal sum of maxillary teeth from the actual sum of mandibular teeth with and the ideal sum of mandibular teeth from the actual sum of maxillary teeth widths.
Q: How many sections are required for the Dental Space Analysis to be applied in CephSmile?
A: Three sections are required including:
- Right Buffer Zone from the right canine to the second right premolar
- Sum of Incisor – four incisal teeth
- Left Buffer Zone from the left canine to the second left premolar
Q: How many types of Bolton ratio analysis can be applied in CephSmile?
A: CephSmile can apply three types including:
- All. 12, the ratio between sum of the madibular teeth and the sum of maxillary teeth from the first right molar to the first left molar.
- Anterior 6, the ratio between sum of the madibular teeth and the sum of maxillary teeth from the right canine to the left canine.
- Posterior 6, the ratio between sum of the madibular teeth and the sum of maxillary teeth from the first right molar to the first left premolar and from the first left molar to the first left premolar.
Q: Regarding orthodontic movement simulation, what priority must be done in step-by-step?
A: The first step is to segment the individual teeth and then move the individual teeth to the targeted position by moving or rotating until all the segmented teeth have their individual destination and the orthodontic movement simulation can be executed until clicking the Stop radiobutton to end the movement.
Q: Can we perform the measurements for Dental Arch Parameters in an arbitrary manner?
A: The user must follow the guidelines or dental arch parameter measurement step-by-step for success.
Q: Can we perform the dental width measurements for Dental Space Analysis and Bolton Analysis in an arbitrary manner?
A: The user must follow the measurement step-by-step from the second right molar to the second left molar and from the maxillary teeth to the mandibular teeth.
Q: Could we save the dental model analysis data?
A: Yes, it can be saved and reopened.
Q: Could CephSmileV2 perform the dental model analyses on the cases of mixed dentition as well as the cases of primary dentition?
A: Unfortunately, not at present due to the lack of research data from Thai people to perform the dental model analyses on the cases of mixed dentition as well as the cases of primary dentition.
