Abstract
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.
Highlights
Implant-supported fixed dental prostheses (FDP) have been a well-established treatment option for dental treatment for the last 40 years since the development of dental implants [1]
external-hexagon connection (EH) groups showed significantly higher strengths than that of the one-body implant (OB) group (p < 0.05), but there was no significant difference between the EH, internal-octagon connection (IO), internal-hexagon connection (IH), and micro-locking implant system (ML) groups (p > 0.05) (Table 3)
It is possible that the part of the abutment that is engaged in the internal connection, which is longer than that of the external connection, affect load-bearing capacity
Summary
Implant-supported fixed dental prostheses (FDP) have been a well-established treatment option for dental treatment for the last 40 years since the development of dental implants [1]. The long-term clinical success of these FDPs are based on the advancement of surface technology, sophisticated surgical techniques, improved stability of the interface between implant, and abutment dental prosthesis, as well as osseointegration [2,3]
