“…For a prosthesis consisting of multiple implants, a new user may find it difficult to ascertain which implants are still engaged and keeping the prosthesis in place. 8,9 The Spread Fit Ti-Base System (SFIT; Cowellmedi, Busan, Korea) consists of a new structural screw and abutment that spreads the upper part of the abutment when screwing and is engaged to the groove on the inner surface of the prosthesis so that retention can be obtained without cement. Because of 11° taper of the Spread Fit abutment, axial divergences up to 22° between two implants can be compensated with these tapered abutment (Figs.…”

Ti-Base System was developed to overcome complications of conventional implant prosthesis system. This system uses a specific locking mechanism between the abutment and prosthesis instead of cement or screws, providing easy retrievability and no possibility of biological complications. This case report introduces clinical experience with a 3 -month follow-up of implant fixed prosthesis fabricated with SFIT Ti -Base System on a right maxillary posterior edentulous site. No biological complications or loss of retention was observed during the observation time. SFIT Ti-Base System is expected to be used in various clinical cases in the future.

“…There have been studies to overcome the limitations of screw- and cement-retained implant prostheses [ 13 , 14 ]. Shah et al [ 13 ] reported on an abutment system that can lock and unlock prostheses by replacing cement layers with precision-machined nickel-titanium sleeves, and Lee et al [ 14 ] reported on an implant prosthesis that could be maintained without cement by lining the surface of the crown with a composite resin. However, the research related to these prostheses is very limited, and the scientific basis is still lacking.…”

The aim of this study was to introduce the newly developed micro-locking implant prosthetic system and to evaluate the resulting its characteristics. To evaluate load-bearing capacity, 25 implants were divided into five groups: external-hexagon connection (EH), internal-octagon connection (IO), internal-hexagon connection (IH), one-body implant (OB), micro-locking implant system (ML). The maximum compressive load was measured using a universal testing machine (UTM) according to the ISO 14801. Retention was evaluated in two experiments: (1) a tensile test of the structure modifications of the components (attachment and implant) and (2) a tensile test after cyclic loading (total 5,000,000 cycles, 100 N, 2 Hz). The load-bearing capacity of the ML group was not significantly different from the other groups (p > 0.05). The number of balls in the attachment and the presence of a hexagonal receptacle did not show a significant correlation with retention (p > 0.05), but the shape of the retentive groove in the implant post had a statistically significant effect on retention (p < 0.05). On the other hand, the retention loss was observed during the initial 1,000,000 cycles, but an overall constant retention was maintained afterward. Various preclinical studies on this novel micro-locking implant prosthetic system should continue so that it can be applied in clinical practice.

“…3 Screw-retained FDPs have advantages including predictable retrievability, a minimal amount of interocclusal space needed, easy hygiene management, and easy removal upon repair or surgical intervention. 4,5 However, screw-retained FDPs may be contraindicated and may require increased production time and cost. 4 In addition, screw-retained FDPs require a high degree of accuracy to achieve a passive fit, 6 and residual stress from screw tightening can occur between the multiunit FDPs and the implant if passive fit is not achieved.…”

“…4 In addition, screw-retained FDPs require a high degree of accuracy to achieve a passive fit, 6 and residual stress from screw tightening can occur between the multiunit FDPs and the implant if passive fit is not achieved. 5 The most common complications to occur with screw-retained prostheses are prosthetic screw loosening, fracture, and prosthesis breakage. 7 Cement-retained FDPs also have advantages including compensation for inappropriately inclined implants, easier achievement of passive fit, the presence of an intact occlusal surface due to the absence of an occlusal access hole, and easier control of occlusion.…”

Implant-supported fixed dental prosthesis with a microlocking implant prosthetic system: A clinical report

A microlocking implant prosthetic system has recently been developed to address the limitations of conventional screw-and cement-retained implant-supported fixed dental prostheses. This prosthesis system consists of a precision-machined abutment and an attachment that includes zirconia balls and a nickel-titanium spring, thus providing retrievability and constant retention of the prosthesis. In addition, screw-related complications are avoided because there is no retention screw. The occlusal access hole is of a smaller diameter than that of conventional screw-retained prostheses, which is beneficial for esthetics and occlusion. It also prevents common complications of cement-retained prostheses because residual cement around the prosthesis can be removed extraorally. This article presents a clinical treatment with this new prosthetic system.
