Definitions
- Systems and methods are disclosed providing a database comprising a compendium of at least one of patient treatment history; orthodontic therapies, orthodontic information and diagnostics; employing a data mining technique for interrogating said database for generating an output data stream, the output data stream correlating a patient malocclusion with an orthodontic treatment; and applying the output data stream to improve a dental appliance or a dental appliance usage.
- the present invention provides methods and apparatus for mining relationships in treatment outcome and using the mined data to enhance treatment plans or enhance appliance configurations in a process of repositioning teeth from an initial tooth arrangement to a final tooth arrangement.
- the invention can operate to define how repositioning is accomplished by a series of appliances or by a series of adjustments to appliances configured to reposition individual teeth incrementally.
- the invention can be applied advantageously to specify a series of appliances formed as polymeric shells having the tooth-receiving cavities, that is, shells of the kind described in U.S. Patent No. 5,975,893.
- the model and resulting appliance can be modified by altering the shape of the unsatisfactory appliance, by adding a dimple, by adding material to cause an overcorrection of tooth position, by adding a ridge of material to increase stiffness, by adding a rim of material along a gumline to increase stiffness, by removing material to reduce stiffness, or by redefining the shape to be a shape defined by the complement of the difference between the intended effect and the actual effect of the unsatisfactory appliance.
- the clinical constraints can include a maximum rate of displacement of a tooth, a maximum force on a tooth, and a desired end position of a tooth.
- the maximum force can be a linear force or a torsional force.
- the maximum rate of displacement can be a linepr 0 r an angular rate of displacement.
- the apparatus of the invention can be implemented as a system, or it can be implemented as a computer program product, tangibly stored on a computer-readable medium, having instructions operable to cause a computer to perform the steps of the method of the invention.

- the ClinCheck® technology uses a patient-specific digital model to plot a treatment plan, and then use a scan of the achieved treatment outcome to assess the degree of success of the outcome as compared to the original digital treatment plan as discussed in U.S. Patent ⁇ Application Serial No. 10/640,439, filed August 21 , 2003 and U.S. Patent Application Serial No. 10/225,889 filed August 22, 2002.
- the problem with the digital treatment plan and outcome assessment is the abundance of data and the lack of standards and efficient methodology by which to assess "treatment success" at an individual patient level.
- a dental data mining system is used.
- FIG. 1 A shows one exemplary dental data mining system.
- dental treatment and outcome data sets 1 are stored in a database or information warehouse 2.
- the data is extracted by data mining software 3 that generates results 4.
- the data mining software can interrogate the information captured and/or updated in the database 2 and can generate an output data stream correlating a patient tooth problem with a dental appliance solution.
- the result of the data mining system of FIG. 1 A is used for defining appliance configurations or changes to appliance configurations for incrementally moving teeth.
- the tooth movements will be those normally associated with orthodontic treatment, including translation in all three orthogonal directions, rotation of the tooth centerline in the two orthogonal directions with rotational axes perpendicular to a vertical centerline ("root angulation” and “torque”), as well as rotation of the tooth centerline in the orthodontic direction with an axis parallel to the vertical centerline (“pure rotation”).
- the data mining system captures the 3-D treatment planned movement, the start position and the final achieved dental position.
- the system compares the outcome to the plan, and the outcome can be achieved using any treatment methodology including removable appliances as well as fixed appliances such as orthodontic brackets and wires, or even other dental treatment such as comparing achieved to plan for orthognathic surgery, periodontics, restorative, among others.
- a teeth superimposition tool is used to match treatment files of each arch scan.
- the refinement scan is superimposed over the initial one to arrive at a match based upon tooth anatomy and tooth coordinate system.
- the superimposition tool asks for a reference in order to relate the upper arch to the lower arch.
- the superimposition tool measures the amount of movement for each tooth by first eliminating as reference the ones that move (determined by the difference in position between the current stage and the previous one) more than one standard deviation either above or below the mean of movement of all teeth. The remaining teeth are then selected as reference to measure movement of each tooth.
- FIG. IB shows an analysis of the performance of one or more dental appliances.
- "Achieved” movement is plotted against “Goal” movement in scatter graphs, and trend lines are generated. Scatter graphs are shown to demonstrate where all "scattered” data points are, and trend lines are generated to show the performance of the dental appliances.
- trend lines are selected to be linear (they can be curvilinear); thus trend lines present as the "best fit” straight lines for all "scattered” data.
- the performance of the Aligners is represented as the slope of a trend line.
- the Y axis intercept models the incidental movement that occurs when wearing the Aligners. Predictability is measured by R 2 that is obtained from a regression computation of "Achieved" and "Goal" data.
- FIG. 1C shows various Movement Type data used in one embodiment of the data mining system.
- Exemplary data sets cover Expansion/Constriction (+/-X Translation), Mesialization/Distalization (+/-Y Translation), Intrusion (-Z Translation), Extrusion (+Z Translation), Tip/Angulation (X Rotation), Torque/Inclination (Y Rotation), and Pure Rotation (Z Rotation).
- FIG. ID shows an analysis of the performance of one or more dental appliances.
- the motion achieved is about 85% of targeted motion for that particular set of data.
- clinical parameters in steps such as 170 (FIG. 2 A) and 232 (FIG. 2B) are made more precise by allowing for the statistical deviation of targeted from actual tooth position. For example, a subsequent movement target might be reduced because of a large calculated probability of currently targeted tooth movement not having been achieved adequately, with the result that there is a high probability the subsequent movement stage will need to complete work intended for an earlier stage. Similarly, targeted movement might overshoot desired positions especially in earlier stages so that expected actual movement is better controlled. This embodiment sacrifices the goal of minimizing round trip time in favor of achieving a higher probability of targeted end-stage outcome. This methodology is accomplished within treatment plans specific to clusters of similar patient cases.
- Table 1 shows grouping of teeth in one embodiment.
- the sign convention of tooth movements is indicated in Table 2.
- Different tooth movements of the selected 60 arches were demonstrated in Table 3 with performance sorted by descending order.
- the appliance performance can be broken into 4 separate groups: high (79-85%), average (60-68%), below average (52-55%), and inadequate (24-47%).
- Table 4 shows ranking of movement predictability. Predictability is broken into 3 groups: highly predictable (.76-.82), predictable (.43-.63) and unpredictable (.10-.30). For the particular set of data, for example, the findings are as follows:
- Incisor intrusion, and anterior intrusion performance are high. The range for incisor intrusion is about 1.7mm, and for anterior intrusion is about 1.7mm. These movements are highly predictable.
- Canine intrusion, incisor torque, incisor rotation and anterior torque performance are average. The range for canine intrusion is about 1.3mm, for incisor torque is about 34 degrees, for incisor rotation is about 69 degrees, and for anterior torque is about 34 degrees. These movements are either predictable or highly predictable.
- Dynamic programming considers all possible paths of M "frames" through N points, subject to specified costs for making transitions from any point i at any given frame k to any point j at the next frame k+1. Because the best path from the current point to the next point is independent of what happens beyond that point, the minimum total cost [i(k), j(k+l)] of a path through i(k) ending at j (k+1) is the cost of the transition itself plus the cost of the minimum path to i(k).
- the values of the predecessor paths can be kept in an MxN array, and the accumulated cost kept in a 2xN array to contain the accumulated costs of the possible immediately preceding column and the current column.
- this method requires significant computing resources.
- transitions are restricted to reentry of a state or entry to one of the next two states.
- Such transitions are defined in the model as transition probabilities.
- the probability a(2,l) of entering state 1 or the probability a(2,5) of entering state 5 is zero and the sum of the probabilities a(2,l) through a(2,5) is one.
- the preferred embodiment restricts the flow graphs to the present state or to the next two states, one skilled in the art can build an HMM model with more flexible transition restrictions, although the sum of all the probabilities of transitioning from any state must still add up to one.
- the next few embodiments allow greater clinician satisfaction and greater patient satisfaction by tailoring treatment parameters to preferences of clinicians.
- the system detects differences in treatment preferences by statistical observation of the treatment histories of clinicians. For example, clinicians vary in how likely they would be to perform bicuspid extraction in cases with comparable crowding. Even when there is not a sufficient record of past treatments for a given clinician, clustering may be performed on other predictor variables such as geographical location, variables related to training, or size and nature of practice, to observe statistically significant differences in treatment parameters.
- practitioners are clustered into groups by observed clinician treatment preferences, and treatment parameters are adjusted within each group to coincide more closely with observed treatment preferences. Practitioners without observed histories are then assigned to groups based on similarity of known variables to those within clusters with known treatment histories.
- FIG. 2 A illustrates the general flow of an exemplary process 100 for defining and generating repositioning appliances for orthodontic treatment of a patient.
- the process 100 includes the methods, and is suitable for the apparatus, of the present invention, as will be described.
- the computational steps of the process are advantageously implemented as computer program modules for execution on one or more conventional digital computers.
- a mold or a scan of patient's teeth or mouth tissue is acquired (110).
- This step generally involves taking casts of the patient's teeth and gums, and may in addition or alternately involve taking wax bites, direct contact scanning, x-ray imaging, tomographic imaging, sonographic imaging, and other techniques for obtaining information about the position and structure of the teeth, jaws, gums and other orthodontically relevant tissue.
- a digital data set is derived that represents the initial (that is, pretreatment) arrangement of the patient's teeth and other tissues.
- the initial digital data set which may include both raw data from scanning operations and data representing surface models derived from the raw data, is processed to segment the tissue constituents from each other (step 120).
- data structures that digitally represent individual tooth crowns are produced.
- digital models of entire teeth are produced, including measured or extrapolated hidden surfaces and root structures.
- the desired final position of the teeth— that is, the desired and intended end result of orthodontic treatment — can be received from a clinician in the form of a prescription, can be calculated from basic orthodontic principles, or can be extrapolated computationally from a clinical prescription (step 130).
- the final position and surface geometry of each tooth can be specified (step 140) to form a complete model of the teeth at the desired end of treatment.
- the position of every tooth is specified.
- the result of this step is a set of digital data structures that represents an orthodontically correct repositioning of the modeled teeth relative to presumed-stable tissue.
- the teeth and tissue are both represented as digital data.
- the process can, and generally will, interact with a clinician responsible for the treatment of the patient (step 160).
- Clinician interaction can be implemented using a client process programmed to receive tooth positions and models, as well as path information from a server computer or process in which other steps of process 100 are implemented.
- the client process is advantageously programmed to allow the clinician to display an animation of the positions and paths and to allow the clinician to reset the final positions of one or more of the teeth and to specify constraints to be applied to the segmented paths. If the clinician makes any such changes, the subprocess of defining segmented paths (step 150) is performed again.
- the current aligner shape is compared to the previously calculated aligner shapes. If the current shape is the best solution so far (decision step 250), it is saved as the best candidate so far (step 260). If not, it is saved in an optional step as a possible intermediate result (step 252). If the current aligner shape is the best candidate so far, the process determines whether it is good enough to be accepted (decision step 270). If it is, the process exits. Otherwise, the process continues and calculates another candidate shape (step 240) for analysis.
- FIG. 3 shows a process 300 of creating a finite element model that can be used to perform step 210 of the process 200 (FIG. 2).
- Input to the model creation process 300 includes input data 302 describing the teeth and tissues and input data 304 describing the aligner.
- the input data describing the teeth 302 include the digital models of the teeth; digital models of rigid tissue structures, if available; shape and viscosity specifications for a highly viscous fluid modeling the substrate tissue in which the teeth are embedded and to which the teeth are connected, in the absence of specific models of those tissues; and boundary conditions specifying the immovable boundaries of the model elements.
- a finite element model of the initial configuration of the teeth and tissue is created (step 310) and optionally cached for reuse in later iterations of the process (step 320).
- a finite element model is created of the polymeric shell aligner (step 330).
- the input data for this model includes data specifying the material of which the aligner is made and the shape of the aligner (data input 304).
- the model aligner is then computationally manipulated to place it over the modeled teeth in the model jaw to create a composite model of an in-place aligner (step 340).
- the forces required to deform the aligner to fit over the teeth, including any hardware attached to the teeth, are computed and used as a figure of merit in measuring the acceptability of the particular aligner configuration.
- the tooth positions used are as estimated from a probabilistic model based on prior treatment steps and other patient information.
- FIG. 4 shows a process 400 for calculating the shape of a next aligner that can be used in the aligner calculations, step 240 of process 200 (FIG.
- the process iterates over the movable teeth in the model. (Some of the teeth may be identified as, and constrained to be, immobile.) If the end position and dynamics of motion of the currently selected tooth by the previously selected aligner is acceptable ("yes" branch of decision step 440), the process continues by selecting for consideration a next tooth (step 430) until all teeth have been considered ("done” branch from step 430 to step 470). Otherwise (“no" branch from step 440), a change in the aligner is calculated in the region of the currently selected tooth (step 450). The process then moves back to select the next current tooth (step 430) as has been described.
- an absolute configuration of the aligner is computed, rather than an incremental difference.
- a process 460 computes an absolute configuration for an aligner in a region of a current tooth. Using input data that has already been described, the process computes the difference between the desired end position and the achieved end position of the current tooth (462). Using the intersection of the tooth center line with the level of the gum tissue as the point of reference, the process computes the complement of the difference in all six degrees of freedom of motion, namely three degrees of translation and three degrees of rotation (step 464). Next, the model tooth is displaced from its desired end position by the amounts of the complement differences (step 466), which is illustrated in FIG. 5B.
- FIG. 5C A further step in process 460, which can also be implemented as a rule 452 (FIG. 5 A), is shown in FIG. 5C.
- the size of the model tooth defining that region of the aligner, or the amount of room allowed in the aligner for the tooth is made smaller in the area away from which the process has decided to move the tooth (step 465).
