Learn how to place UltraTemp REZ II temporary resin cement with a step-by-step provisional cementation process, common mistakes, and practical crown cement tips.

Quick answer

Use UltraTemp REZ II temporary resin cement when you need lasting retention for a provisional restoration. Mix it to a uniform paste, load the crown, seat it with firm pressure, and clean excess before it sets.

Why retention matters for temporary cement

Temporary restorations fail most often because the cement washes out or does not bond well enough to hold the crown through normal function. UltraTemp REZ II is designed for lasting retention, so the placement technique should focus on complete seating and clean margins rather than excess material. A cement that stays put reduces the need for reseating appointments and protects the prepared tooth between visits.

When to choose a resin-based temporary cement

Resin-based temporary cements like UltraTemp REZ II are a good fit for provisionals that must withstand longer wear or higher bite forces. They are not the right choice when you need easy cleanup at the try-in stage or when the provisional will be removed shortly; in those cases, a simpler temporary cement may save chair time. Also consider the restoration material: check compatibility before using any resin cement on a provisional.

Step-by-step provisional cementation with UltraTemp REZ II

Prepare the provisional and tooth: Clean and dry the provisional restoration and the prepared tooth. Remove any temporary cement residue from a previous try-in and confirm the restoration seats fully without rocking. Check that the crown is fully seated before applying cement; incomplete seating will cause a thick cement layer and high bite.
Mix UltraTemp REZ II: Dispense the cement and mix it to a uniform paste according to the manufacturer’s instructions. Avoid incorporating air or leaving streaks. A streaky mix will not set evenly; mix until the color and texture are consistent.
Load and seat the restoration: Fill the provisional crown with cement, place it on the tooth, and apply firm, steady pressure. Ask the patient to bite down on a cotton roll to help full seating. Do not rock or twist the crown during seating; that can trap air and prevent complete adaptation.
Clean excess cement: Before the cement sets, remove excess material from the margins with a scaler or explorer. Work quickly and check all surfaces, including interproximal areas. Leaving excess cement can irritate tissue and create a rough margin; clean while the cement is still soft.
Verify set and occlusion: Allow the cement to set fully, then check retention and occlusion. Adjust if needed and give the patient post-placement instructions. Confirm the crown does not rock or feel high; adjust occlusion before the patient leaves.
