MTO Flashcards
Indications for interceptive treatments 1-6
1) Infraocclusion
2) Mesially erupted permanent tooth
3) Lateral cross-bite
4) Frontal cross-bite
5) Aplasia
6) Supernumerary tooth
Indications for interceptive treatments 7-11
7) Open bite
8) Diasthema medianum
9) Incisor protrusion / retrusion
10) Incisors eruption problems
11) Crowding
Therapy of crowding
Expansion of maxillary arch
Lingual arch appliance
IPR
Hotz serial extraction
Etiology of incisor protrusion
Hereditary Bad habits Persistant milky tooth Lack of space Frontal cross bite Extreme deep bite
Problems associated with mixed dentition
- Premature loss of milky teeth
- Retained milky teeth
- Infra-occluded primary molars
- Impacted 1st permanent molars
- Dilaceration
- Supernumerary teeth
- Habits
- 1st permanent molars of poor long-term prognosis
- Median diastema
Advantages of interdisciplinary approach
+ idealizes and simplifies therapy
+ improves the overall treatment prognosis
+ turns problems into advantages
+ prevents unnecessary procedures
+ shortens treatment time
+ enhances individual team member’s result
+ enhances professional relationships
+ increases satisfaction of patient and doctors

o Subgingivally destructed crowns
o Moving of dissected teeth
Prostho and ortho
o Axis correction o Crossbite treatment o Ectopic teeth o Intrusion of elongated teeth o Absence of tooth germs o Space opening / Space closure o TMJ dysfunction
Oral surgery and ortho
o Implantation o Impacted and retained teeth o Supplementary / Supernumerary teeth o Dysgnathic disorders and developmental jaw abnormalities o Clefts o Mandible fractures
Indications of space closure
- Excessive frontal crowding
- Wide, intact middle incisors
- Not pointed canines
- Lack of intercuspidation of the canine
- Tendency towards mesialization on a given side
Contraindications of space closure
- Excessive diasthema
- Short, narrow central incisors
- Ideal canine contact
- Injured neighbouring teeth
- Missing premolar on the affected side
Macroesthetics - Face esthetics
Profile Vertical proportions Lip Fullness Chin + Nasal projections Other characteristics
Miniesthetics - Smile esthetics
Incisor display Buccal corridor Smile symmetry Crowding Smile Arc Vermillion display
Microesthetics - Teeth esthetics
o Gingival shape + contour
o Black triangles
o Shape + proportions
Frequency of unerupted teeth
Lower wisdom teeth Upper canine Upper wisdom teeth Lower 2nd premolar Upper central incisors Lower canine
Sequence of complex treatment
- Treatment planning
- Preoperative orthodontics
- Definitive treatment plan
- Model surgery
- Surgical intervention
- Postoperative orthodontics
- Prosthodontics
- Plastic surgery
Consequences of CLP
• Underdeveloped + asymmetric face
• Retrognathic maxilla
• Nose deformity: wide and flat appearance
• Septum deviation
• Location and function of the facial muscles change
• Dental problems:
Occlusal abnormalities
Aplasia or abnormal teeth
Irregular eruption of central incisor is frequent
Objectives of cleft treatment
Reconstruct anatomical structures surgically
Orthodontic upper arch correction
Functional habilitation
Nutrition, speech, hearing, facial muscles rehabilitation
Preventing consequential diseases
Psychological care
