Document Use
  • Enter codes on prescriptions or work orders to document the prices of various procedures. (1)
  • Read labels on containers of gold and chemicals. These give weights, density and directions on how to use the material and precautions. (1)
  • Enter information on tooth identification drawings. These are presented in tabular form with two rows referring to each jaw and cells in columns referring to individual teeth. (2)
  • Interpret various charts and tables related to the making of crowns, such as those presenting information on colour, porcelain firing/burnout cycles and measurement conversion. (3)
  • Read Materials Safety Data Sheets (MSDS) to safely use products, especially when they are unfamiliar. (3)
  • Read forms relating to prescriptions or work orders, which may contain check boxes, technical words and phrases, dates, code numbers of teeth, diagrams and hand-drawn sketches, to prepare orders according to their specifications. (3)

Computer Use
  • Use computer-controlled machinery. For example, enter codes to program the temperature of a computer-controlled furnace for firing materials. (1)
  • Use a database. For example, retrieve client files to obtain information. (2)

Oral Communication
  • Talk to suppliers to discuss orders, billing and new product information. (1)
  • Consult with managers to clarify the requirements of a particular prescription. (1)
  • Interact with co-workers to exchange technical information and to discuss company policies and job-related concerns. (1)
  • Interact with new dental laboratory bench workers to provide training, assign tasks and supervise them. (2)
  • Speak with dentists to clarify special instructions noted on prescriptions or work orders. (2)
  • Talk with clients to troubleshoot problems that they may have with their orthodontic appliances. (2)

Scheduling or Budgeting and Accounting
  • Monitor the flow of incoming orders and outgoing work to ensure that co-workers are meeting quotas. (1)
  • Determine whether a customer's deadline request may be accommodated, considering such scheduling factors as the time required to produce each component. (2)
Back to Top

Measurement and Calculation
  • Measure materials for mixing, such as liquid and powder polymers, using a graduated scale in millilitres and a scale in grams. (1)
  • Calculate the weight of metal required for a client's tooth by using a formula to convert the weight of the wax model to the weight of the specific metal to be used. Different formulae are used for different metals. (2)
  • Measure the dimensions of bridges using various callipers to prepare them according to the specifications. (2)
Back to Top

Numerical Estimation
  • Estimate the amount of porcelain needed to complete a construction, based on experience. (1)
  • Estimate the amount of time required to deliver orders to facilitate dentists' appointment scheduling. Accuracy is important because delays impact the schedules of both dentists and their patients. (1)
  • Estimate the angle of tilt at which each tooth is to be set into dentures. (3)

Job Task Planning and Organizing
  • Dental laboratory bench workers receive case assignments, each with a deadline. They have great flexibility in planning and organizing their job tasks to achieve the deadlines. This involves carefully sequencing and timing the multiple steps for each case, such as setting and firing, to maximize efficiency. They are often faced with rush orders and disruptions which require them to reprioritize their work plans to maintain customer satisfaction. (3)

  • Decide whether to contact a dentist directly or speak with the supervisor for further information, considering such factors as familiarity with the dentist's preferences and the quality of the impressions. (1)
  • Decide whether a casting can be repaired within a specified time frame, drawing on their previous experience. (2)
  • Decide among various design choices for dental devices, such as the type of mould to use and the size and angle of the teeth. These decisions are based on many factors such as the type of bite and the location of bone. (3)

Problem Solving
  • When soldering joints, it is found that the solder won't flow. Clean up the solder and redo the work, perhaps several times, until the solder flows properly. (1)
  • A defective appliance has been returned by a client. Dismantle the appliance, salvage what is possible and determine how to rebuild it. (2)
  • There are equipment malfunctions, such as improperly placed rubber seals in pressure pots. Identify the nature and scope of the equipment problem and determine whether work needs to be redone. (2)
  • The modified dentures do not fit comfortably in a client's mouth. Analyze each stage of fabrication to identify the cause of the problem, checking factors such as whether the dentist's original impression was distorted or the die was altered. Then determine the best approach to ensuring a good fit, possibly asking others for advice. (3)
  • A client has returned dentures because lines developed in the finish. Go back through the process to identify the cause of the problem and resolve it appropriately while maintaining good client relations. (3)
