The Curved Bristle
“A toothbrush designed for the manual abilities and psychological preferences of the patients”

The Collis-curve ® is constructed with curved bristles so that the gingival sulcus and interproximal areas can be entered and cleaned with limited manual skill.  By scrubbing indiscriminately, the teeth and sulcus are cleaned and the soft tissue massaged. The Collis-Curve is designed specifically to brush all exposed surfaces of  teeth simultaneously, but can be used with any brushing method depending on the preference of the patient.

Brushing Techniques

 

Dr. Collis' theory on assisted brushing.

Aid and Comfort for the Caregiver and the Patient during Assisted Brushing”

An important aspect in dental care is the psychological effect assisted brushing has on the caregiver as well as the patient.The caregiver, in addition to having the burden of overseeing the patients dental health, also carries the burden of following difficult if not impossible procedures without proper or effective tools. Assisted brushing, with all the complex positional requirements, patient gagging, and negative feedback, becomes a very unrewarding daily chore. .The caregiver becomes discouraged and feels as though his effort  are not  only unappreciated but totally ineffective.  If the caregiver is given the proper tool to work with and reasonably doable instructions he would approach his task with less trepidation and his anxiety would not be transferred to his vulnerable patient. With respect to the psychological effects that assisted brushing has on the patient , the patient has no control over the pressure, placement, or attitude he perceives from his caregiver. In short, if the care giver is given a realistic regimen to follow and he feels he has done a good job, his confidence will be picked up by the patient and a positive psychological environment will prevail.

 

Collis-Curved bristles are shaped like a hygienist's curette for cleaning teeth.

Tilting brush head side-to-side allows curved bristles to slide along enamel surfaces and embrasures of teeth to scoop out debris in sulcus and gumline.
