1FWhere should we place the orthodontic treatment goal?


iPjPractical treatment goal


1.Occlusal relation
PFMid-line
QFFirst molar relation
@@iCanine relationj
RFLower incisal face perpendicular to the occlusal plane
SFUpper incisal face is
@@@@ at an angle of 80-82
@@@ degrees to the occlusal
@@@ plane
TFThe marginal ridge
@@@@ of lateral teeth is smooth
@@@@@ without steps.

UFThe palatal cusp is 0.5 mm down to the buccal@ cusp of maxillary molar.
VFThe buccal@ cusp and lingual cusp of mandible are on the same level.
WFThe frontal view, central incisors,
@@@@@ lateral incisors and canines are on a
@@@@ different level and the buccal surface
@@@@ of lateral teeth are almost pararell.
XFThe buccal surface of mandibular
@@@@@ lateral teeth goes internally gradually.
POFOcclusal view of the arch
@(Orthoform).



2.Cephalometric goal
SNAASNBAANB
U-1 to NA, L-1 to NB
Interincisal Angle
Mandibular plane
Occlusal plane

The treatment goal will be the achievable ANB from patientsfinitial situation



3.Esthetic goal
The position of the lower incisor and anterior coupling
Lip line and Smile line
Vertical dimention
Gonial angle, Facial height
Esthetic line



4.Functional goal
To summarize the cases in order for the maxillary and mandibular teeth bites in centric occlusion when the patientsf mandible is in terminal hinge relation.
To provide an overbite in order for the molar teeth discludes when sliding the mandible protrusive.
The canine will disclude the lateral teeth group during lateral movement of mandible.
There seems to be no problem if the mandible slid protrusive for about 1 mm from CR to CO.
The flatter the occlusal plane is, the overbite can be small.
The lateral shifting acts traumatically to teeth, bone tissue and temporomandibular joint.
No occlusal interference with the opposite tooth during lateral movement of the mandible.



5.Stability
When a treatment is carried out beyond the acceptable limit, the orthodontists always suffer from agony of case relapse after the treatment.

Basic considerations
1. The lower canine width does not expand@@ : Limitation
2. It is functioning appropriately
3.The lower incisors are upright
