Historically, connecting a tooth to an implant is discouraged because differences in tooth and implant mobility would result in the prosthesis being cantilevered to stress the implant [<xref ref-type="bibr" rid="CR2">2</xref>–<xref ref-type="bibr" rid="CR5">5</xref>]. However, splinting the implant and natural tooth is occasionally used as a rational alternative for anatomical structural reasons or patient-centered preferences [<xref ref-type="bibr" rid="CR1">1</xref>–<xref ref-type="bibr" rid="CR5">5</xref>]. Endodontically treated tooth restored used a post and core build-up and full crown is occasionally regarded as an abutment tooth in a TISP with healthy periodontal stability and in dense bone situations [<xref ref-type="bibr" rid="CR4">4</xref>, <xref ref-type="bibr" rid="CR6">6</xref>–<xref ref-type="bibr" rid="CR12">12</xref>]. Potential physiological and engineering problems, such as marginal bone loss and implant or prosthesis complications (fracture) can occur under long-term higher bending moment acting at the implant site owing to the biomechanical dilemma resulting from the dissimilar mobility between an osseointegrated implant and tooth [<xref ref-type="bibr" rid="CR2">2</xref>, <xref ref-type="bibr" rid="CR12">12</xref>–<xref ref-type="bibr" rid="CR16">16</xref>]. However, the literature contains limited and conflicting data that addresses inclusion of abutment teeth with endodontic therapy in a TISP [<xref ref-type="bibr" rid="CR4">4</xref>]. A computer simulation study indicated that a 3-piece implant with a retaining-screw (RS) connection system produced higher stress compared with a 2-piece implant with a taper integrated screw-in (TIS) connection system [<xref ref-type="bibr" rid="CR12">12</xref>]. Unfortunately, the result from this static numerical study requires further evaluation using insight into the in vitro fatigue tests to provide more realistic consultation.</p><p>The acoustic emission (AE) technique is a non-destructive technique that offers the advantages of being a non-stop technique that monitors the condition of materials under investigation throughout the test [<xref ref-type="bibr" rid="CR17">17</xref>, <xref ref-type="bibr" rid="CR18">18</xref>]. Combined with conventional static fracture test machines, AE can identify failure initiation, the initial damage site, damage propagation and catastrophic material failure and help elucidate the complex failure mechanism [<xref ref-type="bibr" rid="CR19">19</xref>–<xref ref-type="bibr" rid="CR26">26</xref>]. However, the AE technique has rarely been employed in dental biomechanical testing under cyclic loads. Studies successfully combined the AE technique with fatigue shear testing to investigate micro-crack growth and damage in ceramic/tooth tissue adhesive interfaces and found that the cumulative number of AE hits increased with a lower load level in cyclic load tests before fracture [<xref ref-type="bibr" rid="CR27">27</xref>, <xref ref-type="bibr" rid="CR28">28</xref>].</p><p>Accordingly, this study applied the AE technique to monitor the resistance in an endodontically treated TISP using different implant macrostructures with 2-(TIS) and 3-(RE) piece implant systems under dynamic cyclic loads. AE signal results at different cyclic load stages were obtained and section-images of the tested samples were evaluated after fatigue testing to understand the biomechanical response in an endodontically treated TISP.</p></sec><sec id="Sec2"><title>Methods</title><sec id="Sec3"><title>Implant static failure test</title><p>A 2-piece implant with a TIS connection and a 3-piece implant with an RS connection were selected as the implant systems for investigation (Fig. <xref rid="Fig1" ref-type="fig">1</xref>). These two different macrostructure implant systems with the same size (4.5 mm in diameter and 13 mm in length) belonged to the same brand (IDEOSS Ltd.

All implants were embedded in an epoxy resin block at a distance 3.0 mm apically from the nominal bone level as the bone-anchoring part for all test specimens. The specimen was then clamped at a 30° angle (considered axial and lateral loads) between the implant axis and load direction in a universal testing machine (E3000, Instron, Canton, MA, USA) to perform the failure test. Compressive load was applied through a loading device (cap) at a rate of 1 mm/min until the force decreased below 20 % of the maximum load or the implant failed. The maximum static test force was determined.</p></sec><sec id="Sec4"><title>Endodontically treated TISP fatigue test</title><p>Ten freshly extracted intact mandibular second premolars with similar size controlling for a maximum deviation of 20 % from the root length and crown dimensions were selected as abutment teeth. The artificial PDL of each premolar was replicated with approximated 0.5 mm thickness around tooth from 1.5 mm below the CEJ to the root using silicon (Gingifast Elastic, Zhermack SpA, Badia Polesine, Italy). Ten abutment teeth and other prepared implants (three implants in each of TIS and RS connection types) were aligned and embedded into an epoxy resin block. The abutment teeth were prepared with a 1 mm wide chamfer finish line and 2 mm ferrule length above the CEJ. The N–Cr alloy post-core was restored and cemented after performing conventional endodontic steps. After wax-up and casting procedures, a Ni–Cr alloy (VeraBond II, Dentech Dental Ltd. London, UK) with two-unit crowns for the premolar and first molar were fabricated and cemented onto the endodontically treated teeth (Fig. <xref rid="Fig1" ref-type="fig">1</xref>).</p><p>The endodontically treated TISP samples were clamped into the INSTRON testing machine to perform the fatigue test. The fatigue test cyclic loads were carried out by applying 20N (Fmin) to 200N (Fmax) onto the abutment tooth with a 4-mm steel sphere contacting the buccal and lingual cusps to simulate the occlusal forces, i.e. the R value (Fmax/Fmin) was set at 10 [<xref ref-type="bibr" rid="CR30">30</xref>, <xref ref-type="bibr" rid="CR31">31</xref>] (Fig. <xref rid="Fig2" ref-type="fig">2</xref>).

All samples were stained, subsequently embedded in epoxy resin and bi-sectioned through the implant axis using a low speed diamond saw with copious cooling (CL50 Precision Saw, Top Tech Machines Co., Ltd., Taipei, Taiwan).

Although TISP used with a rigid connection has been advocated by some authors and found to reduce the risk of abutment-tooth intrusion. However, other influential factors such as implant type should be further evaluated, especially when an endodontically treated tooth is used as the abutment tooth in TISP. This study was designed to focus on how to reduce the risk of implant complications in an endodontically treated TISP. Our previous numerical study indicated that RS (3-piece) implant might induce higher stress when compared with the TIS (2-piece) implant. However, the clinical significance of the results from static finite element (FE) analysis is occasionally questionable because FE analysis results are usually dominated by many numerical assumptions, such as PDL non-linear material property, ill-condition element, load and boundary conditions. Particularly, a monotonic load does not accurately represent a clinical situation in which repetitive fatigue loading is characteristic [<xref ref-type="bibr" rid="CR12">12</xref>].</p><p>Repeated load fatigue has been recognized as an important concept rather than a catastrophic event, inducing TISP failure. The AE technique has also been employed in orthopaedic/dental material dynamic fatigue testing. The AE signal can be regarded as having high sensitivity as it registers even the smallest cracks as long as a noise is generated and thus is claimed to provide real time data [<xref ref-type="bibr" rid="CR19">19</xref>]. Cumulative numbers of AE hits are observed to increase with a lower load level in cyclic load tests before fracture [<xref ref-type="bibr" rid="CR27">27</xref>]. Fracture resistance and small cracks accruing and growth on the testing samples can be estimated depending on the cumulative number of AE hits. Therefore, this study attempted to combine the AE technique to monitor the failure process in an endodontically treated TISP when connected to different implant systems under dynamic loads. The fatigue test result indicated that non-significant differences were found in the accumulated number of AE signals between the RS (3-piece) and TIS (2-piece) implants due to their high standard deviations. A large number of AE signals were found in the four TIS implant samples because the corresponding abutment screws were fractured, producing large standard deviation in this group. This phenomenon can be interpreted as the unstable broken implant structure induced the AE signal to continue to record until the fatigue test was stopped. The AE monitoring system could not identify what load stage lead to the sample fracture during the fatigue test. However, the mean accumulated number of AE signals in the TIS implant were observed higher than those for the RS implant and implied that more micro-cracks might accumulate and grow in the TIS implant. This result can be verified in the implant static failure test that found maximum load for the RS (3-piece) implant (797N) was higher than that for the TIS (2-piece) implant (559N). The static failure testing ensures that the implant or implant/abutment system is subjected to both compressive and shear (lateral) forces, with no lateral constraint occurring. The fracture pattern also evidenced that endodontically treated TISP connected with TIS (2-piece) implant has lower resistance and two of the corresponding samples were broken. This phenomenon indicated that the RS (3-piece) implant might present better mechanical compensation among all components within the implant when receiving the moment condition. The color stained image indicated that a small gap occurred between the crown and tooth in the chamfer in the TIS samples due to the stress concentration generated after the implant broke. These results imply that using the RS (3-piece) implant may be a better option when an endodontically treated tooth is connected to an implant for patients with less than ideal implant sites.</p><p>This in vitro experimental study was designed to understand the relationship between the accumulated number of AE signals and fracture (load) resistance in different implant type connection for endodontically treated TISP. Some clinical situations cannot be fully represented in this study and need to be assumed, such as silicon material was only used to simulate the artificial PDL and complex (lateral) occlusal load conditions was not performed in the fatigue test. The axial load applied on the abutment tooth in this study simulated the bending moment effect on the implant. Standard internal implant-abutment connections, such as 6-point internal hex of passive fit (RS connection) and Morse taper with friction fit (TIS connection) were discussed but external butt-joint connection was not considered in this study. Otherwise, the situation regarding the number of occlusal contacts that occur in vivo, Delong et al. [<xref ref-type="bibr" rid="CR34">34</xref>] addressed that chewing tooth contacts equal 240,000 in 1 year. Ruse et al. [<xref ref-type="bibr" rid="CR37">37</xref>] pointed out that chewing and swallowing contacts equal 1800 per day. These numbers translate into 10<sup>5</sup> in 2–5 months. Owing to the constrained time available for collecting data, a 10<sup>5</sup> cyclic load was used as the relative number to simulate clinical chewing. Therefore, the experimental results provided in this study must be confirmed in further well-controlled long-term clinical trials.</p></sec></body><back><ack><title>Authors’ contributions</title><p>CLL conceived and designed the experiments; SFH and WRC performed the simulation and experiment; SFH analyzed the data; SFH and CLL wrote the manuscript.
