Premier’s Orthotic Process – The Building of a Great Orthotic

Orthotic Process Premier Orthotic Labs Burlington

In order for POL to supply you with a truly custom product, we first receive a foam or plaster cast impression of your foot corrected in sub-talar neutral.

Once your cast impression is received, we start our Quality Control process.

Your order and the selected materials and choice of correction as well as shoe selections is confirmed by our dedicated and highly competent customer service team.

Measurements of the cast are taken and marks are placed on the negative cast impression to indicate bony prominences such as 1st met head and 5th met head, navicular and sulcus line. The Calcaneous is marked for mid line vertical and then a plaster positive mould is made from the negative cast.

Process of pouring liquid plaster into plaster and foam negatives to make a plaster positive.

Once the plaster is cured, the negative mould is broken away and discarded. The markings on the negative cast impression transfer onto the new plaster positive.

The rear foot and fore foot are corrected to lab evaluation or otherwise instructed via the prescription form (Rx form).

Once the plaster positive is corrected another Quality check is performed including a complete evaluation of the cast dressing, rear foot alignment, forefoot alignment in plane with the rearfoot and amount of tissue expansion necessary.

The Rx form will indicate which types of materials to use in the fabrication process and any other special instructions.

The shell material selected will be heated and then vacuum moulded following specific standards used at POL based on the material, its thickness and overall desired effect of support required by the patient.
