Can Different Impression Techniques Affect the Chewing Efficiency of Mandibular Implant-Retained Overdentures?

Area of Science:

• Dental Prosthodontics
• Biomaterials Science

Background:

• Implant-retained overdentures offer improved function for edentulous patients.
• Various impression techniques exist, each with unique benefits and drawbacks.

Purpose of the Study:

• To compare the chewing efficiency of mandibular implant-retained overdentures fabricated using three distinct impression techniques: mucofunctional, selective pressure, and minimal pressure.

Main Methods:

• Twenty-six completely edentulous patients received three sets of mandibular implant-retained overdentures, each using a different impression technique.
• Chewing efficiency was assessed three months post-prosthesis insertion for each technique.

Main Results:

• The mucofunctional impression technique group demonstrated significantly higher mean chewing efficiency parameters compared to the selective and minimal pressure groups.
• This suggests a superior outcome in functional restoration with the mucofunctional approach.

Conclusions:

• The mucofunctional impression technique appears to be more effective in enhancing the chewing efficiency of mandibular implant-retained overdentures compared to selective and minimal pressure techniques.
• This technique may offer improved patient satisfaction and functional rehabilitation for complete edentulism.
