A toothbrush designed for the manual abilities and psychological preferences of the patients

An important aspect in dental care is the psychological effect assisted brushing has on the caregiver as well as the patient. The oral hygiene of the people caregivers help may become neglected if they are feeling overwhelmed by balancing their many duties, patients, and own self-care. Brushing another person’s teeth is a difficult procedure that requires appropriately designed cleaning aids and training on the complex positional requirements needed to maintain a proper technique.

As a result of not having proper tools or training, toothbrushing becomes a very unrewarding daily chore for caregivers.

Inducing negative feedback from the patient, like gagging, can discourage the caregiver and cause them to feel as though their efforts are not only unappreciated but totally ineffective.

If caregivers were given the proper tool to work with and reasonably doable instructions, they would approach this task with less trepidation and their anxiety would not be transferred to the defenseless person needing aid with daily oral infection control.

In short, if caregivers are given a realistic regimen to follow and they feel as though a good job has been done, their confidence will be felt by the patient and a positive psychological environment will prevail.


Collis Curve adaptive toothbrush makes oral care easy for Alzheimer patients. Watch the interaction between patient and caregiver during guided brushing and daily infection control is accomplished with ease and care.

Suggested procedures for assisted brushing:


Find a toothpaste that the person likes and fill the Collis Curve Toothbrush with toothpaste.


Slide brush over teeth until curved bristles touch gumline. If the person resists, do a circular scrub on the outside of their teeth until the person will let you cover his tooth with the brush. It may take a few days, but your problems will soon be over.



Move the handle laterally to brush back and forth on each quadrant of the mouth for 30 seconds. While doing this, tilt brush head side-to-side to allow curved bristles to slide along enamel surfaces and embrasures of teeth to scoop out debris in sulcus and gumline.


Use as a regular brush for a finishing scrub on the front teeth and any areas that may need extra care.

Dr. Collis demonstrates how the Collis Curve adaptive toothbrush uses standard obstacles to assisted brushing, such as patient biting down on brush and shaking, to enhance engagement with tooth surfaces and gingival massage.

Simultaneous brushing has made its way into research and dental literature.
