BDS 2 ORTODONSIA 'ANALISIS GIGI CAMPURAN MOYERS' by Waode Nabila Aulia Anggana_160110230105

Summary

In this presentation, Waod Nabila Aulia, a student from the Faculty of Dentistry at Padjajaran University, discusses the mixed dentition analysis, focusing on the Moyers method. She explains how this method helps evaluate the available space in the jaw for permanent teeth during the mixed dentition stage. Aulia covers the step-by-step process for measuring mesiodistal widths of teeth, adjusting them using Moyers' prediction table, and applying different calculation methods. The presentation also compares the long and short methods for measurement, providing insights into how the analysis aids orthodontic assessments.

Takeaways

• 😀 Mixed dentition is the stage where both deciduous and permanent teeth have erupted in the oral cavity, and it plays a critical role in orthodontic assessment.
• 😀 Mixed dentition analysis helps evaluate the available space in the jaw for permanent teeth and assists in determining necessary occlusal adjustments.
• 😀 Moyer’s Mixed Dentition Analysis is widely used because it minimizes systemic errors, and its error range is well-known.
• 😀 The first step in Moyer’s analysis is to measure the mesiodistal width of erupted permanent teeth, as well as the unerupted canines and premolars.
• 😀 The mesiodistal width measurements are carried out in stages, starting with the mandibular lateral incisor, central incisor, and continuing to the right mandibular teeth.
• 😀 After taking the initial measurements, the results are added up and then adjusted using Moyer's prediction table to estimate the space needed for unerupted teeth.
• 😀 The long method in Moyer’s analysis involves detailed measurements and adjustments using factors from the Moyer prediction table for greater accuracy.
• 😀 The short method is a simpler approach that divides the mandibular incisor measurements by two and adds either 10.5 mm for mandibular or 11 mm for maxillary arch predictions.
• 😀 The second stage of Moyer’s analysis involves measuring the available space in the jaw for the eruption of permanent teeth, divided into different segments such as first molar to second premolar, central to lateral incisors, and more.
• 😀 Total space available is determined by summing up the measurements from various segments in the jaw, providing an estimate of the available space for teeth to erupt.
• 😀 The reference used for Moyer’s Mixed Dentition Analysis is Robert A. Moyer's 1988 'Handbook of Orthodontics,' 4th edition, which is widely recognized in the field.

Q & A

What is mixed dentition?

Mixed dentition refers to a stage in dental development when both deciduous (baby) teeth and permanent teeth are present in the oral cavity.

Why is mixed dentition analysis important in orthodontics?

Mixed dentition analysis helps in assessing the available space in the jaw for permanent teeth and determining necessary occlusal adjustments. It is an essential part of orthodontic evaluation.

What is the purpose of Moyers' mixed dentition analysis?

The purpose of Moyers' mixed dentition analysis is to predict the width of unerupted permanent teeth, especially canines and premolars, using measurements of erupted mandibular incisors.

What is the first step in Moyers' mixed dentition analysis?

The first step is to measure the mesiodistal width of the erupted mandibular incisors. This includes measurements for the left and right mandibular central and lateral incisors.

How are the measurements used in Moyers' analysis for prediction?

The measurements of the mandibular incisors are used along with Moyers' prediction tables to estimate the size of unerupted canines and premolars, which are crucial for determining available space in the jaw.

What is the difference between the long and short methods in Moyers' analysis?

The long method involves more detailed tooth measurements and uses the full prediction table, while the short method is simpler, using just the width of the mandibular incisors with a fixed adjustment.

What are the adjustments made after measuring the mesiodistal widths?

After measuring the mesiodistal widths of the mandibular incisors, adjustments are made based on the Moyers prediction table to obtain the estimated widths of the unerupted permanent teeth.

What does the final step of the Moyers analysis involve?

The final step involves adding the measurements of the mandibular incisor teeth with those of the premolars and canines to determine the total space needed in the jaw.

How do you calculate the space available in the jaw for permanent teeth?

The available space is calculated by measuring different segments of the jaw, such as the width of the teeth from the central incisors to the second premolar and from the canines to the second premolars, and then adding up all the segment measurements.

What is the significance of the measurement reference from Robert A. Moyers?

The reference from Robert A. Moyers' 1988 'Handbook of Orthodontics' provides established guidelines and prediction tables for the analysis, ensuring accuracy and minimizing systemic errors.
