Impression making remains the most vital step for a successful prosthesis placement after surgical phase of implant therapy. Open-tray technique has been the most advocated method to make accurate impression in implantology. In case of making impression for multiple implants, various methods have been used for splinting of transfer copings in open-tray technique. This article mentions the use of a novel material for stabilizing splinting transfer copings.

| Introduction|| |
Open-tray technique has been proven to be the most accurate method for impression making in implantology. Splinting of transfer copings is usually done to prevent micromovement. This article describes the use of composite-based material for stabilization.
- Attach transfer copings on implant head after removing the gingival former
- Use dental floss (Oral-B) to splint the transfer copings for better stability [Figure 1]
- Extrude Protemp (3M ESPE) and adapt them over the floss using a plastic instrument [Figure 2]. The advantage of using Protemp is that it can be handled easily
- Proceed with the regular impression technique usually followed for opentray method.
| Discussion|| |
Splinting of open-tray transfer copings is usually followed when multiple implants are placed in an arch. Splinting material should be selected based on their property to resist any dimensional changes. This is done to prevent the movement of individual copings during impression making. Unsplinted impression copings may show individual movement which contributes to its greatest inaccuracy., The brush-bead technique for pattern resin may show polymerization shrinkage. The accuracy of flowable composite has also been studied by Selvaraj et al. However, it polymerizes by light and requires the use of light-emitting device. Any dual-cure composite has the advantage of ease of handling of material. The less polymerization shrinkage ensures that the splinting remains stable. The amount of material used is less. The advantage of material outweighs the cost since the impression obtained is very accurate due to the stability of transfer copings.
| Conclusion|| |
The use of a temporary dual-cure restorative material such as Protemp proves to be very helpful for splinting of transfer copings in implant-level impressions.
