For many years, there was a quest To fully describe the position and orientation of the to identify the most stable and reliable landmarks within dentition in the facial skeleton and its relationship to the skull to use as reference points for cephalometric the facial soft tissues is exactly analogous to what is analysis.

Longitudinal forward and backward thrust Vertical aircraft moves upward and downward Lateral aircraft moves from side to side.

Pitch, roll, and yaw are descriptors that can be used for the esthetic line of the dentition. Pitch represents the occlusal plane in sagittal view, roll is analogous to the occlusal plane in frontal view, and yaw is a way of describing rotation of the dentition and jaws around a vertical axis.

Yaw problems are manifested as midline deviations, facial asymmetries, or Angle subdivision molar relationships. Such an assume that the appearance of practically any smile can innovation would render the cephalostat obsolete. At least part of the clinical examination should be Thus, the orthodontic decision-making process today done with the head in NHP, cephalograms should be begins at the first visit with a kind of triage, whereby the taken in NHP, and the orientation of three-dimensional initial decision is merely to decide whether the patient images should be corrected to NHP.

Once NHP is has a complex condition requiring extensive records and established with a true vertical axis, the teeth and the analysis or a simpler condition primarily related to jaws can be oriented to the rest of the craniofacial enhancement of smile esthetics. After making this judg- complex by using the occlusal plane as the other refer- ment, the two processes whereby the orthodontist estab- ence plane. The difference in the less complex Complex versus Simpler Patients case relates to the variety of diagnostic records required In this chapter, the overall approach to diagnosis is rec- and the depth in which they must be assessed prior to ommended.

Nevertheless, the fact that many patients making a treatment recommendation. In short, the major seeking an orthodontic consultation have already made difference between the two diagnostic processes is the a self-diagnosis, namely that they simply want braces, robustness of the database. If treatment is entirely elec- has in certain ways changed the diagnostic ground rules. These patients or parents lengthy or complicated. The classic anatomic planes of the face are coronal, sagit- tal, and transverse.

In the Ackerman-Proffit classification, the sagit- tal plane is referred to as anteroposterior, the coronal plane is designated vertical, and the transverse plane is the same as the occlusal plane and is used as a reference for the relative widths of the dental arches and any crossbite relationships that might exist.

When the three discs representing the three planes of space are rotated, they demonstrate pitch, roll, and yaw of the occlusal plane. During a when the sagittal disc rotates, it creates pitch of the occlusal plane; clinical examination, it is important to visualize the orientation of and when the transverse plane rotates, it simulates yaw. This model makes it clear how the anteroposterior, transverse, vertical, pitch, roll, and yaw are highly dependent on one another.

As has already been stated, the key to the effective use of It has been shown that orthodontists are able to base the problem-oriented approach to orthodontic treatment their treatment-planning decisions primarily on informa- planning is to establish an appropriate database prior to tion derived from study models or photographs with generating a problem list.

Yet, the second key to effective treatment ironing out of a few wrinkles in a smile, it is certainly planning is to thoroughly review the data contained in not necessary to have a CBCT scan, as an example, as the database.

On the other hand, if an impacted structing the database is to make sure some feature of the canine is identified from viewing a panoramic radio- orthodontic condition is not being overlooked prior to graph, the highest standard of care today is to obtain compiling the problem list.

There is a minimum standard three-dimensional imaging before making any final for necessary orthodontic records, but there is no longer treatment-planning decisions Figure , A and B.

For instance, an orthodontist may choose surgically exposed and its eruption orthodontically to acquire a supplemental posteroanterior cephalometric assisted or whether some other plan might make more radiograph for an individual with asymmetry or, perhaps sense. The alternatives in this case are to either extract even better, would consider that individual a candidate the canine and try to preserve the central incisor for as for CBCT , but it is superfluous to obtain a frontal radio- long as possible or extract the central incisor with the graphic image for every candidate for treatment.

Data Collection at the First Contact. For this patient, although the position of the impacted canine and the significant resorption of the root of the central incisor can be seen clearly from the panoramic image and from the lateral cephalogram, there are many cases where the additional imaging is very useful in making a prudent decision about which tooth to extract the impacted canine or the compromised central incisor in a difficult situation like this one.

Tx complexity determined must be asked. The first, of course, is when the patient at initial patient assessment last saw his or her physician. If it was within the last year and was for a regular checkup, this usually is a One-step process Triage Two- or three-step process good sign.

Another important question is whether the patient has ever been hospitalized and, if so, for what reason. This may be Additional records for Supplemental a clue that the patient had an earlier airway problem, confirmation of plan diagnostic records which might have affected the jaw and tongue posture.

The next issue that must be considered is whether the as a checklist to guide the receptionist in systematically patient is taking any medications.

If a patient has recently naire from the office website, having it e-mailed to been prescribed isotretinoin Accutane for severe cystic them as an attachment, or having it mailed to them as a acne, the orthodontist and patient should be aware that hard copy.

The advent of more prevalent than currently suspected. The treatment coordinator, immediately prior or adolescents who have unrealistic expectations about to the orthodontist meeting the patient, usually takes what orthodontic treatment might accomplish for them. After briefly Perhaps the easiest and most direct way to find out reviewing these records and rallying his or her thoughts, how the patient feels about orthodontic treatment is to the orthodontist is ready to meet the patient.

Most children today think that braces are inevi- when he or she meets the patient; some find it advanta- table and thus usually answer affirmatively. Occasionally, geous to examine a child patient independently first and the reaction is a shrug of the shoulders.

For the the patient if there is no parent present. Nor should the dentist require orthodontics, an important question is whether focus on the functional implications of, for instance, a any one feature is of greater concern than another. It is crossbite with a lateral shift without appreciating the important to know this for two reasons. As we have noted, failing to address an issue that is of major concern to the for an individual with what appears to be reasonably patient.

After having assessed the overall head and face, the orthodontist then focuses on the lower face, which is most easily affected by tooth position. Lip prominence is usually described as convex, straight, or concave, and this judgment is made relative to the nose and chin. A large nose and well-developed chin can easily mask a protrusive dentition.

Similarly, the opposite situation of a small nose and weak chin can make a child appear more facially convex. Examining the parents and older siblings may give some hint regarding final dimensions of these structures. At some point but some features must be examined chairside.

In most instances, the clinician simply classifies faces from a ver- tical standpoint as short, average, or long Figure In terms of anterior tooth display, a smile is characterized by how well the teeth and gingival fit within the smile zone, which is defined by the lips.

A more detailed analysis of facial form and appearance is pre- sented in Esthetic Orthodontics and Orthognathic Surgery19 and in Chapter 2 of this volume.

Step 2: Analysis of the Alignment and Intra-arch Symmetry. Alignment is the key word in this group; among the possibilities are ideal, crowded arch length deficiency , spaced, and mutilated. It is obviously impor- tant to count the teeth in order to ascertain which teeth are present or absent. For example, if a tooth terior divergence of the chin in relationship to the mid-face and is lingually displaced, it is said to be in linguoversion.

If upper face. Adding a description of face height, as well, nicely completes the picture see Figure Today, the important observation rests with recognizing either an increased or decreased lower face height. Long, narrow faces with increased lower face height usually have a tendency toward anterior open bite. Lower anterior face height is a reflection of the underlying skeletal pattern.

Individuals with short lower face heights usually have relatively parallel horizontal facial planes i. Patients with long lower face heights have horizontal facial planes that tend to converge posteriorly see Figure Of course, there are many exceptions to these rules. If a opposite is true of patients with short anterior face heights tooth is tipped mesially, it is in mesioaxiversion, and if i.

For other patients, it will not be necessary to make any measurements on the cephalometric film to arrive at an accurate diagnosis and reasonable treatment plan.
