Abstract
Abstract Artificial dentures are accurately and precisely constructed using a dental articulator which is rigid, nonyielding and which stores, preserves and makes available every determinant required to build accurate intercuspation of teeth. A unique transparent tooth-setting guide which allows rapid ''''see-through'''' mounting of the casts, indicates the size of the teeth suitable for the case and guides the placement of the teeth. With the dental articulator and transparent tooth-setting guides dentures are constructed by (1) establishing the occlusal plane on the biterim or on the teeth, (2) mounting the lower cast on the articulator in a manner to preserve the plane of occlusion, the mounting making use of the transparent tooth setting guide, (3) mounting the tooth-setting guide to the lower cast, (4) mounting the lower cast to the articulator, (5) mounting the upper cast and (6) arranging the teeth in the casts.

Claim 1
Independent Claim
237 words
A method of accurately and precisely constructing artificial dentures comprising: 1. providing biterims of the lost teeth of the patient mounted on casts, 2. orienting the biterims and casts to the occlusal plane, 3. providing a dental articulator having an upright posterior post of rugged construction, upper and lower arms extending parallel to one another at substantially right angles from the upper and lower ends of the posterior post, the upper arm hinged to the posterior post for vertical movement, the upper and lower arms being of rugged construction so that the vertical height between them cannot be varied by ordinary hand pressure, 4. securing the casts firmly in position to the arms of the articulator while mounting to prevent accidental movement or dislodgement thereof, 5. mounting the casts, 6. removing one of the mountings from an arm of the articulator, 7. securing a transparent arcuate tooth-setting guide having openings in the body thereof over the biterim of the cast secured to the articulator, the guide providing vision for physically arranging teeth on the cast against the occlusal plane established by the guide, access to the arranged teeth through the openings to make any corrections in their position, and an indication of the size of the teeth to be used in construction, and 8. physically arranging teeth on the cast against the occlusal plane established by the tooth-setting guide through openings in the body of the guide.

Claim 4
Dependent Claim
9 words
orienting the biterims and casts to the occlusal plane,
Claim 5
Dependent Claim
68 words
The method of claim 1 wherein the casts are secured in step (4) by (a) securing the transparent tooth-setting guide over the biterim of the cast in a manner to prevent movement relative to the biterim either horizontally or vertically and (b) securing the tooth-setting guide to either arm of the articulator at a fixed height and in a manner to prevent rotation thereof relative to the arm.
Claim 6
Dependent Claim
69 words
providing a dental articulator having an upright posterior post of rugged construction, upper and lower arms extending parallel to one another at substantially right angles from the upper and lower ends of the posterior post, the upper arm hinged to the posterior post for vertical movement, the upper and lower arms being of rugged construction so that the vertical height between them cannot be varied by ordinary hand pressure,
Claim 7
Dependent Claim
69 words
providing a dental articulator having an upright posterior post of rugged construction, upper and lower arms extending parallel to one another at substantially right angles from the upper and lower ends of the posterior post, the upper arm hinged to the posterior post for vertical movement, the upper and lower arms being of rugged construction so that the vertical height between them cannot be varied by ordinary hand pressure,
Claim 8
Dependent Claim
