Orthodontic diagnosis involves three steps—collection of data, processing of the collected data and finally drawing conclusions. Step one is generally the simplest. It basically involves the taking of case history, intraoral and extra-oral examination of the patient, making of study models and taking the relevant radiographs or other diagnostic records. The second step involves the processing of all this collected information into understandable and coherent data. This will involve undertaking cephalogram and study model analyses. The treatment planning is the second step in orthodontic treatment, the treatment planning include determination of the aims of treatment and formulation of an appropriate treatment plan. In order to formulate an appropriate treatment plan, the clinician needs to competent in history taking, examination of patient and collection of appropriate records.

Basic principles in orthodontic treatment planning Oral health The first part of any orthodontic treatment plan is to establish and maintain good oral health. All active diseases like caries and periodontal diseases must be fully treated before beginning any orthodontic treatment while definitive restoration such as crowns and bridge must be placed after alignment of teeth. The lower archTraditionally treatment planning is based around the lower labial segment. The rest of the occlusion can be planned around it. In most cases it is advisable to maintain the current position of the lower labial segment, this is because the lower labial segment is positioned in an area of relative stability between the tongue lingually and the lip labially. Any excessive movement of the lower labial segment would increase the risk of relapse. Lower incisors may be proclined in the following cases: Cases presenting with very mild lower incisors crowding. Treatment of deep overbite, particularly in cl II div.2. Patient who had a digit-sucking habit (where the lower incisors have been retroclined).
