THE D2 APPLIANCE TAKES ADVANTAGE OF DECREASED RESISTANCE, MAKING MOVEMENT EASIER AND FASTER.
D2 APPLIANCE IS A MOLAR DISTALIZING APPLIANCE COMPRISED OF TWO SEPARATE COMPONENTS THAT ATTACH WHEN BONDED ON THE TEETH. THE MOLAR COMPONENT HAS A LARGE, MICROETCHED, EIGHTY GAUGE MESH PAD TO MAXIMIZE BOND STRENGTH. A FREE-FLOATING BAR COMES ATTACHED TO THE BUCCAL OF THE DISTAL COMPONENT WHICH ALLOWS FOR MOVEMENT IN ALL THREE PLANES AND CUSTOM SIZING TO FIT ALL PATIENTS.
Patient visits are scheduled 8-12 weeks apart. Adults may benefit more quickly by bonding maxillary 1st bicuspid to 2nd molar instead of cuspid to first molar. It is important to consider the amount of resistance and relative anchorage to determine appropriate force. In general, 1/4” 4oz elastics are sufficient to move teeth when maxillary 2nd molars are not fully erupted. If 2nd molars are fully erupted, 3/16” 4oz may result in better movement. Additional mesial-out molar rotation may be obtained by increasing the bend at the molar end using a three-prong plier at any routine check visit. The appliance is usually worn 4-6 months. It can also be used in mild Class III cases by bonding the D2 on the lower arch. Sample Class II case below before Invisalign treatment: Photo on right taken at 2nd visit. Appliance was removed at this appointment and the patient was scanned for start of Invisalign. Patent is pending. Questions may be directed to Dr. Todd Dickerson at D2Appliance@gmail.com.
