A Uniform Recording Method for Surgical Workup on Study Models WILLIAM

On occasion a workup is performed on an orthognathic surgery patient, but the details of the planned orthodontic and surgical manipulations are forgotten. The orthognathic surgery workup form (Fig 1, facing page) enables the measurements made on the study models to be recorded in a logical, easyto-read manner. The orthognathic surgery workup form is useful to both surgeons and orthodontists. The form should be kept as part of the patient’s record and referred to as needed. Also, a copy of the form can be sent to the orthodontist before the orthognathic surgery. Following the surgery, postsurgical records can be analyzed, and an accurate measurement of change can be obtained and evaluated.

FIGURE 1. The following correspond to the numbered areas on the form: 1) The patient’s name and case number. 2) The date on which the records were taken. 3) The date the case is worked up. This indicates how recent the records are. 4) The number or method of identification of the articulator used. 5) A brief description of the malocclusion. 6) Indication from where measurements are taken. For example, some clinicians prefer to measure to a specific scribed line, and others to the mounting plate. 7) The setting of the incisal guide pin. 8) Measurements taken on the casts before any orthodontic or surgical movements are done. 9) Measurement of the distance from the incisal guide pin to the incisal edge of the central incisors (Fig 2). 10) Measurement from the previously indicated reference line (No. 6) to the incisal edge or cusp tip. This value indicates the baseline occlusal heights (Fig 3). 11) Measurement of the distance from the back of the cast to the central incisal edge. A change in facial or lingual position of the incisor can be deduced. 12) The intra-arch distance between corresponding cusp tip or central fossa to central
