Abstract
Abstract Premarked dental dams and devices for marking dental dams, are mechanisms that are employed for locating holes to be selectively pierced by the dentist in the dental dam through which teeth protrude. The markings follow the average alignment of teeth as they appear in the dental arch. The patterns of the markings of the teeth of the lower arch are located on the dental dam with respect to the superior edge of the dental dam. One group of patterns represents the primary, mixed and permanent dentition for a 5-inch X 5-inch dental dam. Another group of patterns represents the primary, mixed and permanent dentition for a 6inch X 6-inch dental dam. The pattern of the group selected for a particular arch is dependent on the tooth of that particular arch to be clamped.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
137 words
A device for locating a marking on a dental dam which marking is pierced to form a hole through which hole a tooth protrudes comprising: a rigid body with a superior edge; means on said body defining a first pattern for a lower dental arch, pattern is spaced a predetermined distance from the superior edge of said body and follows the alignment of teeth as they appear in the lower dental arch; and means on said body defining at least one second pattern for a lower dental arch, said second patterns being spaced apart from said first pattern in a direction perpendicular to said superior edge, each of said second patterns being spaced a predetermined distance from the superior edge of said body and follows the alignment of teeth as they appear in the lower dental arch.
Claim 2
Independent Claim
137 words
A device for locating a marking on a dental dam which marking is pierced to form a hole through which hole a tooth protrudes comprising: a rigid body with a superior edge; means on said body defining a first pattern for a lower dental arch, pattern is spaced a predetermined distance from the superior edge of said body and follows the alignment of teeth as they appear in the lower dental arch; and means on said body defining at least one second pattern for a lower dental arch, said second patterns being spaced apart from said first pattern in a direction perpendicular to said superior edge, each of said second patterns being spaced a predetermined distance from the superior edge of said body and follows the alignment of teeth as they appear in the lower dental arch.
Claim 3
Dependent Claim
51 words
A device as claimed in claim 1 and comprising means on said body defining a second pattern for an upper dental arch, which second pattern is spaced a predetermined distance from the superior edge of said body and follows the alignment of teeth as they appear in the upper dental arch.
Claim 4
Dependent Claim
55 words
A device as claimed in claim 2 and comprising means on said body defining a third pattern of holes for an upper dental arch, which third pattern of holes is spaced a predetermined distance from the superior edge of said body and follows the alignment of teeth as they appear in the upper dental arch.
Claim 5
Dependent Claim
40 words
A device as claimed in claim 1 wherein one of said second patterns of said lower dental arch follows the alignment of teeth as they appear in the upper dental arch in response to said rigid body being rotated 180*.
Claim 6
Dependent Claim
15 words
A device as claimed in claim 1 wherein said first pattern is formed by openings.
Claim 7
Dependent Claim
15 words
A device as claimed in claim 1 wherein said first pattern is formed by projections.
Claim 8
Dependent Claim
18 words
A device as claimed in claim 3 wherein said first, second and third patterns are formed by openings.
Claim 9
Dependent Claim
18 words
A device as claimed in claim 3 wherein said first, second and third patterns are formed by projectiOns.
Claim 10
Dependent Claim
141 words
A dental dam in which a hole is pierced and through which hole a tooth protrudes comprising: a flexible sheet with a superior edge; markings on said sheet defining a first pattern of markings for a lower arch which pattern of markings is spaced a predetermined distance from the superior edge of said sheet and follows the alignment of teeth as they appear in the lower dental arch; and markings on said sheet defining at least one second pattern of markings for a lower dental arch, said second patterns of markings being spaced apart from said first pattern of markings in a direction perpendicular to said superior edge, each of said second patterns of markings being spaced a predetermined distance from the superior edge of said sheet and follows the alignment of teeth as they appear in the lower dental arch.
Claim 11
Dependent Claim
141 words
A dental dam in which a hole is pierced and through which hole a tooth protrudes comprising: a flexible sheet with a superior edge; markings on said sheet defining a first pattern of markings for a lower arch which pattern of markings is spaced a predetermined distance from the superior edge of said sheet and follows the alignment of teeth as they appear in the lower dental arch; and markings on said sheet defining at least one second pattern of markings for a lower dental arch, said second patterns of markings being spaced apart from said first pattern of markings in a direction perpendicular to said superior edge, each of said second patterns of markings being spaced a predetermined distance from the superior edge of said sheet and follows the alignment of teeth as they appear in the lower dental arch.
Claim 12
Dependent Claim
55 words
A dental dam as claimed in claim 9 and comprising markings on said sheet defining a second pattern of markings for an upper dental arch, which second pattern of markings is spaced a predetermined distance from the superior edge of said sheet and follows the alignment of teeth as they appear in the upper arch.
Claim 13
Dependent Claim
56 words
A dental dam as claimed in claim 10 and comprising markings on said sheet defining a third pattern of markings for an upper dental arch, which third pattern of markings is spaced a predetermined distance from the superior edge of said sheet and follows the alignment of teeth as they appear in the upper dental arch.
Claim 14
Dependent Claim
17 words
