Abstract
Abstract A trim tooth positioner is constructed to cover only the incisal edges and cusps of the teeth themselves. The result is that the majority of the bulk covering the teeth and gums is eliminated. This significantly increases patient comfort and greatly overcomes the major disadvantage of positioners, that is, poor patient cooperation. The performance is equal or superior to that of other positioner designs in that enhanced cooperation far outweighs any advantage offered by bulk.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
376 words
An improved tooth positioner utilizing tooth contacting edges for actively moving individual teeth to or toward an ideal centric occulsion position by simultaneously engaging, moving, and positioning said individual teeth of upper and lower teeth by force being exerted on contacting edges and a minimal area of adjacent sides of buccal and lingual surfaces of each individual tooth by the act of biting into said tooth positioner, comprising: a one piece preform tooth impression means for providing resilient lateral force to individually move and position individual teeth of said upper and lower teeth by simultaneously engaging only the contacting edges of said upper and lower teeth and a minimal adjacent area of said buccal and lingual surface of each tooth of said upper and lower teeth, said one piece preform tooth impression means for forcing said contacting edge of each tooth to move each said tooth into the most ideal centric occulsion and cusp-fossa relationship by the act of biting into said one piece preform tooth impression means with said upper and lower teeth and for retaining said contacting edge and a minimal adjacent area of said buccal and lingual surfaces of each individual said tooth in the most ideal centric occulsion and cusp-fossa relationship by the act of biting into said one piece preform tooth impression means with said upper and lower teeth, said one piece preform tooth impression means for providing a comfortable, light prostetic device that enhances a user's cooperation for continued use, said one piece preform tooth impression means having separated resilient tooth impressions for individual teeth of said upper and lower teeth situated in certain select positions generally at the ideal centric occulsion and cusp-fossa relationship, said one piece preform tooth impression means having a top with individual upper contacting edge tooth impressions and a bottom with individual lower contacting edge tooth impressions, said upper contacting edge tooth impressions and lower contacting edge tooth impressions covering a minimal adjacent area of the buccal and lingual surface of approximately two to three millimeters of each tooth of said upper teeth and said lower teeth, said upper contacting edge tooth impression and said lower contacting edge tooth impression terminating well short of contact with gum tissue of said upper and said lower teeth.
