Aim: To splint implant impression copings using long shank carbide burs for definitive implant impressions.
Background: The accurate transfer of the orientation recorded by impression copings to a definitive cast is a challenging step in implant prosthodontics. For achieving a passive fit from the mouth to the cast may include some discrepancies. Traditional methods of splinting can be time-consuming and troublesome to handle. Technique: This article describes a technique by using long shank carbide burs for splinting implant impression copings.
Conclusion: The favored implant splinting, evidence was inconclusive, and the data supporting splint pickup was the better performing technique, especially with an increased number of implants.
Clinical significance: This technique causes minimal discomfort and is straightforward when compared to other techniques.
