Lip bumper therapy effectiveness varies by design. While both types controlled incisor tipping, larger acrylic shields resulted in more molar tipping and greater transverse expansion in orthodontic patients.

Area of Science:

  • Orthodontics
  • Dental Biomaterials
  • Craniofacial Growth

Background:

  • Lip bumper appliances are used in orthodontics to influence dentofacial development.
  • Variations in lip bumper design and activation protocols may impact treatment outcomes.
  • Understanding these differences is crucial for optimizing orthodontic treatment strategies.

Purpose of the Study:

  • To compare the effects of two distinct lip bumper designs on orthodontic treatment.
  • To evaluate the influence of fabrication material and activation frequency on cephalometric and model changes.
  • To determine the impact on mandibular incisor position, posterior segment dental movements, and transverse dimensions.

Main Methods:

  • Two groups of 20 patients received lip bumper therapy.

  • Group 1: Stainless steel wire with shrink tubing, activated every 2-3 months.
  • Group 2: Larger prefabricated acrylic shields, activated every 4-5 weeks.
  • Pretreatment and posttreatment lateral cephalograms and study models were analyzed.

    • Main Results:

    • No significant difference in mandibular incisor position or controlled incisal tipping between groups.
    • Significant differences in posterior segment dental movements observed.
    • Group 2 exhibited significantly more molar tipping and greater transverse expansion of canines, premolars, and molars.

    Conclusions:

    • The type of lip bumper and activation method did not affect mandibular incisor position.
    • Different lip bumper designs lead to varying effects on posterior dental segments.
    • Larger acrylic shield lip bumpers promote increased molar tipping and transverse expansion.
