Abstract: Objective: The prevention of traumatic lip injuries due to uncontrollable lip biting may be a challenge in the care of patients with (infantile) cerebral palsy. This is even more difficult when the dental anchorage options for a lip bumper are limited.

Case Report: A patient with dyskinetic cerebral palsy after perinatal asphyxia first presented at the Department of Orthodontics, in 2010 at the age of three years with severe injuries of the lower lip. Therapy was successfully performed by inserting a lip bumper, that was fixed with bands on the second primary molars. When she lost tooth 85 at the age of 8, further attemps at fixing the lip bumper dentally failed and the condition of the lip deterioriated again. Since we installed a skeletally fixed lip bumper, which we developed from two modified Mentoplates® (PSM Medical Solutions, Germany), the patient has been asymptomatic.

Conclusion: For the prevention of traumatic lip injuries due to uncontrollable lip biting, the use of a band-fixed lip bumper is a common treatment option. Since a lot of patients exhibiting that behaviour have a mixed dentition, future attachment attempts may be frustrating. In these cases, a skeletally fixed lip bumper may be the better long-term solution.
