“…The use of pins will probably continue to decrease given the risks of placement and the advent of more durable adhesive bonding agents and composite resins (6,35,36). This in vitro research proved and concluded that the retentive shoulder design offers a conservative and safe approach in the prevention of early failures by enhancing and increasing the micro retention and resistance form of core builds-ups when restoring structurally compromised vital posterior teeth.…”

This study evaluated the influence of a retentive shoulder design to prevent early failure of three resin composite build-ups on molars. Ninety-six intact extracted human maxillary third molars were assigned to two groups (n=48) based on occlusal, buccal cusps only and all cusps reduction. The groups were divided into two subgroups: pin retained and non-pin retained build-ups resulting in four groups (n=24), according the cusps reduction: pin retained/partial, pin retained/complete, non-pin retained/partial, non-pin retained/complete. Occlusal reduction was 3 mm with a semi-lunar retentive shoulder of 3 mm and an axial wall height of 1.5 mm. Groups were restored using a microhybrid, flowable or titanium reinforced resin composite. Modified self-curing acrylic resin provisional crowns were fabricated, cemented with non-eugenol temporary cement and thermal cycled. An instron machine applied tension to the provisional crowns parallel to the long axis of the tooth until dislodgement. A three-way analysis of variance was conducted on the influence of the variables on the retention of the core build-up. Ninety-three build-ups were retained under tensile load, while three core build-ups without pins were dislodged. Three-way analysis of variance showed no statistically significant difference between core build-ups using a retentive shoulder and pin retained core build-ups when tested under tensile load. With the advent of adhesive systems, increased surface area and retentive shoulder design can provide a retentive core foundation to prevent early failures of core build-ups during indirect restoration fabrication which will contribute to the longevity of final restorations.

Wurzelkanalbehandelte Zähne wurden oftmals "reflexartig" aus vermeintlichen Stabilisierungsgründen mit einem Stift restauriert. In der restaurativen Zahnheilkunde gibt es zahlreiche Möglichkeiten, die den Stift im Wurzelkanal bedingen oder relativieren können. Ziel der hier vorgestellten differenzialtherapeutischen Aspekte ist es, dass wurzelkanalbehandelte Zähnebei korrekter Indikation oftmals auch ohne Stiftlangfristig restauriert werden können.
