Which bite registration option is easy to trim and comfortable but may have less dimensional stability than PVS?

• A. Alginate
• B. Wax
• C. Polyether
• D. Zinc oxide-eugenol paste

Answer: (A)

Alginate bite registrations are favored when you want something that’s comfortable for the patient and easy to trim after setting. Its pliable, forgiving nature makes it pleasant for the mouth and simple to remove excess material with a scalpel or blade. The trade-off is dimensional stability: alginate can change shape with water absorption or loss and over time, so it’s not as stable as PVS. PVS bite registrations are highly dimensionally stable, which is why alginate is considered less stable in comparison. The other options tend to be either harder to trim, less comfortable, or more prone to distortion under clinical conditions, making alginate the best fit for the described criteria.
