Luscent Anchors from Dentatus USA
The effectiveness of esthetic fiber resin posts for core stabilization and reinforcement of endodontically treated teeth has been proven again and again in 2 decades of research. Here are some tips for clinical success.
Unlike many clinical innovations used regularly in esthetic dentistry procedures, the effectiveness of esthetic fiber resin posts for core stabilization and reinforcement of endodontically treated teeth has been proven again and again in 2 decades of research.
Strength and Reinforcement
While the concept of flexure in natural teeth has been written about extensively, a post-and-core restoration must be an integrally sealed unit that does not yield, bend, or flex. Extreme impact forces should be absorbed by the periodontal complex, and the internal structures of the root should be reinforced to resist fracture. With fiber resin posts, when excessive force occurs, impact is at the postand- core interface, preserving the remaining root for future restorative procedures. This has lead to an evolution in the research on restoring endodontically treated teeth. The focus has shifted from the post itself to maximizing the post/core complex in function.
Enter Dentatus USA?s Luscent Anchors, combining strong longitudinal fiberglass rods encapsulated in a resin matrix with a modulus of elasticity similar to dentin. Additionally, the glass fibers contain silica, similar to the fillers of composite materials. This construction enables the posts to homogeneously attach to the canal and core material, creating a monobloc for exceptional strength and longevity. The resulting post and core is retentive and antirotational because sound radicular and coronal structure is maintained. Let in the Light Luscent Anchors transmit polymerizing light within the canal, allowing composite curing within the canal and refl ecting natural hues for lifelike esthetics. The radiolucent anchors transmit the tooth color without being visible under most adverse light conditions. They also provide asound core/crown gingival interface, radiating natural color through soft and hard tissues surrounding teeth. Luscent Anchors can be used with dual-cure resins and bonding techniques, which allow suffi cient time for exact centering and seating of the anchor, as well as a complete fi ll of the composite inside the canal. The Luscent Anchor integrally bonded to the composite core/crown complex provides durable support with natural background hues for esthetic restorations.
Compatible with all restorative materials, Luscent Anchors are compatible with all conventional adhesive techniques and materials. The posts can be placed in very narrow and large canals. They are offered in 6 size and diameter combinations, ranging from 15 mm long and 1 mm diameter up to 19 mm long and 1.80 mm diameter.
Dentatus also offers another fiberglass resin post-and-core system?Twin Luscent Anchors. Also offering a combination of light transmission and esthetics, Twin Luscent Anchors have a slim mid-section that creates a ?physical choke? for enhanced retention and assurance against accidental debonding. Additionally, Twin Luscent Anchors incorporate a vent groove that eliminates air resin entrapment and prevents rotational dislocation.
