Hollow obturator with removable lid.

Area of Science:

• Biomedical Engineering
• Prosthetics and Orthotics

Background:

• Obturator prostheses are used to replace missing anatomical structures.
• Weight reduction is a key factor in prosthesis comfort and usability.
• Different hollow obturator designs exist, each with specific functional characteristics.

Purpose of the Study:

• To review the benefits of hollowing obturator prostheses.
• To compare the advantages of closed and open hollow obturator designs.
• To highlight the benefits of obturator prostheses with removable lids.

Main Methods:

• Literature review of existing studies on obturator prosthesis design.
• Analysis of functional benefits associated with different hollow obturator configurations.
• Description of advantages pertaining to removable lid mechanisms.

Main Results:

• Hollowing the obturator significantly reduces prosthesis weight.
• Both closed and open hollow obturator designs offer unique advantages.
• Obturator prostheses incorporating a removable lid present additional, described benefits.

Conclusions:

• Weight reduction through hollowing is a primary benefit for obturator prostheses.
• The choice between closed and open hollow designs depends on specific patient needs.
• Removable lid obturators offer further advantages that enhance prosthesis utility.
