Essentials of Orthodontics

Diagnosis and Treatment

• Broschiertes Buch

Produktbeschreibung

Essentials of Orthodontics: Diagnosis and Treatment is designed to help dental students, orthodontic residents, and general dentists understand the basic concepts and procedures essential to the diagnosis, treatment planning, and treatment of patients who have relatively simple malocclusion problems.

The authors explain the steps of diagnosing basic orthodontic problems and analyzing dental radiographs and include many of the forms and charts dentists use for examination, diagnosis, and appliance design. Readers will learn about the mechanics of how appliances move teeth, the different types of appliances, and the orthodontic materials on the market. The authors also explain and demonstrate through color photos how to take dental impressions, create plaster casts, how to write a laboratory prescription for each appliance and how to create the various fixed and removable appliances. A needed text for the dental student, it is also an excellent resource for dentists wanting to expand their practice.

Key Features:
Practical manual for both diagnosing and developing treatment for simple malocclusions
Sample orthodontic forms
Examples show how to accurately write laboratory prescriptions for orthodontic devices
Step-by-step photos show appliances being created and used in treatment
