Dental implant support significantly improves chewing performance in complete denture wearers. Implant-supported dentures require fewer chewing strokes compared to conventional dentures, enhancing masticatory efficiency.

Area of Science:

  • Dentistry
  • Biomaterials Science
  • Clinical Trials

Background:

  • Complete denture wearers often experience reduced masticatory performance.
  • Mandibular denture support can be achieved through mucosa or dental implants.
  • Implant-supported dentures offer enhanced stability compared to conventional dentures.

Purpose of the Study:

  • To compare the masticatory performance of complete denture wearers based on mandibular denture support.
  • To evaluate the impact of implant-retained overdentures versus conventional dentures on chewing efficiency.

Main Methods:

  • A clinical trial was conducted with complete denture wearers.
  • Participants received either a conventional mandibular denture (mucosa-borne), an implant-mucosa-borne overdenture (two IMZ-implants), or a mainly implant-borne overdenture (transmandibular implant).

  • Masticatory performance was assessed by the number of chewing strokes required for particle size reduction.

    • Main Results:

    • Conventional denture wearers needed 1.5 to 3.6 times more chewing strokes than implant-retained overdenture wearers.
    • No significant difference in masticatory performance was observed between IMZ-implant and transmandibular implant groups.
    • Increased denture stability from implants positively impacts chewing efficiency.

    Conclusions:

    • Implant support for mandibular dentures significantly enhances masticatory performance in complete denture wearers.
    • Denture stability, rather than the specific type of implant support, is the primary determinant of improved chewing function.
    • Dental implants offer a substantial improvement in masticatory efficiency for denture users.
