  • 1. OPEN BITE – TREATMENT PLANS INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  • 2. INTRODUCTION Anterior open bite is one of the most difficult orthodontic problems to correct. The etiology of anterior open bite may be both complex and difficult to establish and yet is critical in developing treatment regimen that will produce stability and satisfactory cosmetic results www.indiandentalacademy.com
  • 3. SIMPLE OPEN BITE Tongue thrust causing anterior deformation is called simple open bite. Moyers(1964) www.indiandentalacademy.com
  • 4. COMPLEX OPEN BITE Combined tongue thrust causing both an anterior and posterior open bite is called complex open bite. It is more difficult to treat. Moyers(1964) www.indiandentalacademy.com
  • 5. ETIOLOGY  EPIGENETIC AND  ENVIRONMENTAL FACTORS ARE BOTH OF CONCERN IN THE ETIOLOGY OF OPEN BITE. www.indiandentalacademy.com
  • 6. EPIGENETIC FACTORS • Includes 1. Posture,morphology and size of the tongue. 2. Skeletal growth pattern of maxilla & mandible. 3. Vertical relationship of the jaw base. www.indiandentalacademy.com
  • 7. ENVIRONMENTAL FACTORS • Abnormal function and improper respiration are the most significant. • Disturbed or occluded nasal respiration can cause a change in the function of both tongue and mandible which can lead to open bite. www.indiandentalacademy.com
  • 8. TREATMENT • Treatment depends on localization and etiology of malocclusion. • Treatment plan varies for dentoalveolar and skeletal open bite. www.indiandentalacademy.com
  • 9. DENTO ALVEOLAR OPEN BITE 1. Habit control 2. Elimination of abnormal perioral musculature function www.indiandentalacademy.com
  • 10. SKELETAL OPEN BITE • Redirection of growth is possible during the active growth period. • Management in adults is by surgery/ orthodontic treatment. www.indiandentalacademy.com
  • 11. TREATMENT IN THE MIXED DENTITION • Control of abnormal habits. • Elimination of dysfunction. • Deforming muscle activity -treatment with screening appliance or activator. • Skeletal open bite-extra oral orthopaedic appliances such as chin caps can be used www.indiandentalacademy.com
  • 12. (Contd.) Selection of appropriate treatment depends on the type of open bite.Three types of open bites may be differentiated: • Dento alveolar • Skeletal • Combined www.indiandentalacademy.com
  • 13. DENTO ALVEOLAR OPEN BITE • It occurs as a consequence of various dysfunctions. • Early mixed dentition Screening therapy is indicated. • Late mixed dentition Multi attachment fixed appliance is indicated. www.indiandentalacademy.com
  • 14. SKELETAL OPEN BITE Treatment depends on at least 2 factors: • Severity of malocclusion. • Possibility of dentoalveolar compensation Treatment options include: • Growth modification • Orthodontic camouflage www.indiandentalacademy.com
  • 15. COMBINED OPEN BITE Because of the dual nature of etiology a combined treatment approach is recommended. Treatment follows 2 possible combinations. • Elimination of abnormal perioral muscle function. • Improvement of skeletal relationship. www.indiandentalacademy.com
  • 16. TREATMENT IN THE PERMANENT DENTITION Multiattachment fixed mechanotherapy is the method of choice with guided extraction procedures to correct dento alveolar problems and compensate for any skeletal problems that exist. www.indiandentalacademy.com
  • 17. (Contd.) • Functional appliances are helpful in the retention phase of therapy. • In adults surgical intervention with pre/post surgical orthodontics needs to be considered. www.indiandentalacademy.com
