Also shown is a method adapted from Ohno et.al. This is easier than any method of clips or putty that we have tried, and it is extremely accurate. This simple time saver has increased our use of bonded upper retainers. Bonding retainers and restoring cusp tips It is highly advisable to restore worn our cusp tips by bonding them onto teeth at the same time retainers are bonded. Ricketts has stated that orthodontists should be the masters of occlusion.
Proper occlusion depends on functioning cusp tips, especially canine cusp tips.
Canine cusp tips are usually the first to be worn away in Class II malocclusions. Orthodontists, not only general practitioners, realize the value of canine disclusion in protecting posterior teeth during lateral jaw excursions. Bonding is accomplished by holding the wire firmly in place with elastomers 1 or simple dental floss, while conditioning and sealing the entire lingual surface of the canines. Then, P50 3M filled posterior composite is feathered over the wires and light cured. Care should be taken to keep the composite off of normal occlusal surfaces.
