Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
56 words
A method for bonding orthodontic brackets to teeth comprising the steps of: a) applying a photopolymerisable adhesive to the base of the bracket or a tooth; b) applying the bracket to said tooth in the desired position; and c) directing a pulsed radiation source to said bracket and tooth so as to cure said photopolymerisable adhesive.
Claim 2
Independent Claim
56 words
A method for bonding orthodontic brackets to teeth comprising the steps of: a) applying a photopolymerisable adhesive to the base of the bracket or a tooth; b) applying the bracket to said tooth in the desired position; and c) directing a pulsed radiation source to said bracket and tooth so as to cure said photopolymerisable adhesive.
Claim 3
Dependent Claim
21 words
The method according to claim 1 wherein said pulsed radiation source has a primary emission in the visible spectrum wavelength region.
Claim 4
Dependent Claim
22 words
The method according to claim 1 wherein said pulsed radiation source has an emission in the 380 to 600 nanometer wavelength region.
Claim 5
Dependent Claim
23 words
The method according to claim 1 wherein said pulsed radiation source reaches a peak power in the range of about 1×10 6 watts.
Claim 6
Dependent Claim
26 words
The method according to claim 1 wherein the pulsed radiation source is pulsed at a frequency in the range of 0.01s -1 to 0.50s 1 .
Claim 7
Dependent Claim
17 words
The method according to claim 1 wherein the pulsed radiation source is pulsed 10 times per second.
Claim 8
Dependent Claim
29 words
The method according to claim 1 wherein said pulsed radiation source is directed at said bracket and tooth for a time period in the range of about 3-5 seconds.
Claim 9
Dependent Claim
22 words
The method according to claim 1 wherein said bonding adhesive includes a means for continuing to cure the adhesive during post-radiation excitation.
Claim 10
Dependent Claim
27 words
The method according to claim 1 wherein a plurality of orthodontic brackets are simultaneously subjected to said pulsed radiation source so as to cure said photopolymerisable adhesive.
Claim 11
Dependent Claim
16 words
The method according to claim 1 wherein said pulsed radiation source is directed through the bracket.
Claim 12
Dependent Claim
19 words
The method according to claim 1 wherein said placed radiation source is directed toward said bracket through said tooth.
Claim 13
Dependent Claim
19 words
The method according to claim 1 wherein pulsed radiation source is directed to said bracket at two angled positions.
Claim 14
Independent Claim
106 words
The method of bonding orthodontic brackets to teeth comprising the steps of: a) cleaning and preparing the surface of the teeth in the area to which the bracket is to be applied; b) rinsing the teeth and then drying said teeth; c) etching the surface of the teeth for a predetermined time; d) rinsing said teeth with water; e) drying said teeth; f) applying a photopolymerisable adhesive to the surface of the tooth or bracket; g) applying the bracket to the tooth in the desired area; and h) directing a visible pulsed radiation source toward said bracket and tooth so as to cure said bonding adhesive.
Claim 15
Independent Claim
106 words
The method of bonding orthodontic brackets to teeth comprising the steps of: a) cleaning and preparing the surface of the teeth in the area to which the bracket is to be applied; b) rinsing the teeth and then drying said teeth; c) etching the surface of the teeth for a predetermined time; d) rinsing said teeth with water; e) drying said teeth; f) applying a photopolymerisable adhesive to the surface of the tooth or bracket; g) applying the bracket to the tooth in the desired area; and h) directing a visible pulsed radiation source toward said bracket and tooth so as to cure said bonding adhesive.
Claim 16
