Introduction</title><p>The use of short implants (<8 mm), especially in jaws with less bone height, has long been a source of debate and has been associated with a low success rate [<xref rid="B1" ref-type="bibr">1</xref>, <xref rid="B2" ref-type="bibr">2</xref>]. However, the development of implant designs such as the plateau root form [<xref rid="B3" ref-type="bibr">3</xref>] and implants with surface structures has increased the success rate to above 90% [<xref rid="B1" ref-type="bibr">1</xref>].</p><p>Primary stability, which depends on surgical technique (immediate versus normal placements, stage 1 versus stage 2) and the properties of the bone in which the implant is placed (types I, II, III, and IV), is important for dental implant success [<xref rid="B4" ref-type="bibr">4</xref>]. In bone of poor quality, increasing implant diameter may be the only way to increase tolerance to occlusal forces, improve initial stability, and provide a favorable stress distribution to the surrounding bone [<xref rid="B5" ref-type="bibr">5</xref>]. Finite element analyses have also suggested that maximum bone stress is particularly related to implant design but practically independent of implant length [<xref rid="B6" ref-type="bibr">6</xref>]. Successful osseointegration has been documented [<xref rid="B7" ref-type="bibr">7</xref>], and systemic factors such as advanced age and smoking [<xref rid="B8" ref-type="bibr">8</xref>] may be related to failure to achieve osseointegration and wound healing [<xref rid="B9" ref-type="bibr">9</xref>].</p><p>The Bicon short implant system (Bicon, LLC) is a screwless implant system. The implant and implant-abutment unit connect with a 3° locking taper in a screwless system [<xref rid="B10" ref-type="bibr">10</xref>]. The high-friction force created by the locking taper breaks down the titanium oxide layer, and the metals become fused together in a cold weld [<xref rid="B10" ref-type="bibr">10</xref>]. This locking taper connection-type implant with conical abutment has the potential to develop a microbial seal [<xref rid="B10" ref-type="bibr">10</xref>, <xref rid="B11" ref-type="bibr">11</xref>], leading to decreased peri-implant bone loss due to microbial invasion and successful osseointegration.</p><p>In the present study, we retrospectively investigated the cumulative survival rates of Bicon short implants (shorter than 8 mm) and compare them with 8 mm implants according to patient variables in a 5-year cohort study using radiological assessments during long-term follow-up.</p></sec><sec id="sec2"><title>2. Methods</title><sec id="sec2.1"><title>2.1. Study Design and Sample</title><p>The present study was a retrospective cohort study. We retrieved patient data, including radiographs, from medical records.

Study Variables</title><sec id="sec2.2.1"><title>2.2.1. Demographics and Health Status</title><p>All patient data, including age, gender, and systemic conditions, were noted before the surgical procedure. Age was classified as older or younger than 60. Patients who were categorized as being medically compromised, patients with evidence of bone disease, relevant drug consumption, skeletal asymmetries or trauma, congenital disorders, and pathological disorders of the maxilla or mandible, and syndromic patients were excluded.</p></sec><sec id="sec2.2.2"><title>2.2.2. Anatomical Variables</title><p>From patient files and radiographs, implant location and bone quality (types I–III; there were no type IV cases) were noted. Bone quality was ascertained clinically at the time of implant placement according to surgeon judgment. The two radiologist coauthors investigated patient panoramic X-rays (<xref ref-type="fig" rid="fig2">Figure 2</xref>) in terms of bone quality. All radiographs were taken with a conventional (Planmeca Proline, Helsinki, Finland) imaging unit at machine settings of 66–70 kVp, 6 mA (Eastman Kodak Co., Rochester, NY, USA), or with a digital unit (Planmeca ProMax) at 66–70 kVp, 8 mA, as recommended by the manufacturer. All postsurgical radiographs were obtained as digital panoramic radiographs. The conventional film radiographs were digitized with a flatbed scanner (Epson Expression 10000 XL) with a transparency adapter. Digitization was performed at 300 dpi and in grayscale. Digital films were stored in a computer database using the manufacturer's software (Dimaxis Pro, version 4.0.5, Planmeca).</p></sec><sec id="sec2.2.3"><title>2.2.3. Implant-Specific Variables</title><p>The Bicon Integra-CP system (Bicon, LLC) was used (<xref ref-type="fig" rid="fig1">Figure 1</xref>). Implant-related variables included length (5–8 mm), diameter (3–5 mm), and well size (2-3 mm). It was also noted whether the surgery was a two-stage surgery or an immediate or normal surgical placement. Normal implant placements were carried out in edentulous crestal bone areas. From the patient files, we also noted whether the type of restoration for each implant was a fixed or removable (overdenture) prosthesis.</p></sec><sec id="sec2.2.4"><title>2.2.4. Implant Survival Evaluation</title><p>Implant failure was the primary outcome variable.

Results</title><p>In total, 111 patients were treated with 371 short Bicon implants supporting fixed and removable prostheses.

Of the patients, 47 (39.9%) were women. All patients were in good health and 28% were smokers (<xref ref-type="table" rid="tab1">Table 1</xref>). Descriptive implant variables are summarized in <xref ref-type="table" rid="tab2">Table 2</xref>.</p><sec id="sec3.1"><title>3.1. Implant Survival Findings</title><p>The mean duration of clinical follow-up was 22.8 (range, 2–51) months after surgical placement of the implants (<xref ref-type="table" rid="tab3">Table 3</xref>). In total, 10 of the 371 implants failed, giving a cumulative survival rate of 97.3% with, on average, 22.8 months of follow-up (Tables <xref ref-type="table" rid="tab2">2</xref> and <xref ref-type="table" rid="tab3">3</xref>). All failures occurred during the healing or osseointegration phase before prosthetic loading.</p><p>Detailed statistical analyses revealed that some factors (demographic, smoking, and anatomical factors) were related with implant success. Patients with implants (<8 mm) older than 60 years had a higher failure rate than the patients under 60 years (<italic>P</italic> < 0.05; <xref ref-type="table" rid="tab4">Table 4</xref>). However, no significant difference was found for 8 mm implants according to age groups in terms of implant failure (<italic>P</italic> > 0.05). Overall, again no statistical significant difference was found according to gender groups in terms of implant failure for both <8 mm and 8 mm groups (<italic>P</italic> > 0.05).</p><p>There was no significant difference (<italic>P</italic> > 0.05) between tobacco users and nonsmokers in terms of implant survival rate (<xref ref-type="table" rid="tab5">Table 5</xref>) for both groups. However, surgical implant placement technique (immediate versus normal placements) significantly affected the survival rate of short implants (<italic>P</italic> < 0.05).

Similarly, there was no effect of prosthetic rehabilitation on implant failure rate for all implant groups (<xref ref-type="table" rid="tab9">Table 9</xref>).</p></sec></sec><sec id="sec4"><title>4. Discussion</title><p>After loading, all of the short implants were functional with no complications. Consistent with previous studies, all implant failures were seen in the early phases of treatment [<xref rid="B1" ref-type="bibr">1</xref>, <xref rid="B12" ref-type="bibr">12</xref>, <xref rid="B13" ref-type="bibr">13</xref>].</p><p>One of our main findings is the cumulative survival rate of 97.3% with, on average, 22.8 months of follow-up. The second major finding is the average marginal bone loss of 0.41 mm in the same follow-up time. Consistent with our results, Gentile et al. [<xref rid="B2" ref-type="bibr">2</xref>] reported a survival rate of 95.2% in patients with short implants during a 1-year follow-up. Vandeweghe et al. [<xref rid="B14" ref-type="bibr">14</xref>] reported a survival rate of 96.5% in 13 patients with short implants supporting single crowns (2 implants failed).</p><p>Short dental implants have become more popular in recent years because of increased survival and success rates due to changes in design and structural features [<xref rid="B1" ref-type="bibr">1</xref>–<xref rid="B4" ref-type="bibr">4</xref>, <xref rid="B9" ref-type="bibr">9</xref>, <xref rid="B10" ref-type="bibr">10</xref>, <xref rid="B13" ref-type="bibr">13</xref>–<xref rid="B17" ref-type="bibr">17</xref>]. One of the more popular short dental implant systems is the Bicon short implant (Bicon, LLC), which has a conical, 3.0° locking taper, is screwless, and has a plateau root form. The plateau root form provides some benefits in terms of healing and osseointegration, where the healing chambers become filled with a blood clot, which is eventually replaced with new bone, leading to biomechanical fixation [<xref rid="B15" ref-type="bibr">15</xref>]. When this process takes place as expected, it leads to significantly improved healing patterns compared to screw root form implants [<xref rid="B15" ref-type="bibr">15</xref>]. Plateau designs also have greater surface areas despite being shorter, maximizing osseous contact [<xref rid="B12" ref-type="bibr">12</xref>]. A significant advantage of having an abutment-implant connection with a locking taper is that there are no screws that can loosen or fracture or other component failures. It also seals the margin of the abutment—crown—implant interface, which can harbor bacteria [<xref rid="B10" ref-type="bibr">10</xref>]. Because of these benefits, Bicon short implants (<8 mm) were used to rehabilitate the patients in the present study.</p><p>Vehemente et al. [<xref rid="B18" ref-type="bibr">18</xref>], using the same type of implant as in the present study, reported 12- and 60-month survival rates of 95.2% and 90.2%, respectively. Rossi et al. [<xref rid="B19" ref-type="bibr">19</xref>] reported a survival rate of 95% in a cohort study of 6 mm implants with 24 months of follow-up. Finally, many other studies have reported survival rates of short implants ranging from 88% to 100% [<xref rid="B1" ref-type="bibr">1</xref>, <xref rid="B4" ref-type="bibr">4</xref>, <xref rid="B9" ref-type="bibr">9</xref>, <xref rid="B12" ref-type="bibr">12</xref>, <xref rid="B13" ref-type="bibr">13</xref>].</p><p>In the present study, implants in patients over 60 years old had a lower survival rate (91.84%) than those in younger patients for <8 mm implants (98.14%, <italic>P</italic> < 0.05). These findings may be related to systemic factors that decrease vascularity or contribute to delayed wound healing, such as those seen in the elderly and smokers [<xref rid="B8" ref-type="bibr">8</xref>, <xref rid="B9" ref-type="bibr">9</xref>]. In contrast, Gentile et al. [<xref rid="B2" ref-type="bibr">2</xref>] reported that the mean age of patients at implant placement did not affect the survival rate of implants.</p><p>In the present study, surgical procedures affected the survival rate. Implants that were placed using the normal surgical technique had a higher survival rate (<italic>P</italic> < 0.05) than those placed using the immediate surgical technique for both <8 mm and 8 mm implants. Prosthetic loadings were conducted 3–8 months after implant placement, and two-stage surgeries were the other standardized techniques used. Immediate placement of implants has several advantages: fewer surgical interventions, shorter treatment time, ideal three-dimensional implant positioning, presumptive preservation of alveolar bone at the side of tooth extraction, and soft tissue esthetic features [<xref rid="B20" ref-type="bibr">20</xref>]. In contrast with the present findings, most studies have suggested no difference between immediate and delayed surgical placement of short implants in terms of survival rate [<xref rid="B20" ref-type="bibr">20</xref>–<xref rid="B23" ref-type="bibr">23</xref>]. In a 2-year follow-up study by Palattella et al. [<xref rid="B22" ref-type="bibr">22</xref>], 16 patients received single tooth replacement with immediate implants and a control group received implants at healed sites; they did not find a statistically significant difference in marginal bone loss between the test and control groups. Other studies have reported similar results [<xref rid="B20" ref-type="bibr">20</xref>, <xref rid="B22" ref-type="bibr">22</xref>, <xref rid="B24" ref-type="bibr">24</xref>].</p><p>In the present study, survival rate factors including gender, tobacco usage, and restoration type did not affect the survival rate of implants but placed region, age, and bone quality did (<italic>P</italic> < 0.05). Consistent with the present findings, Kumar et al. [<xref rid="B8" ref-type="bibr">8</xref>] reported that smoking was not related to implant survival or the osseointegration process, especially when using surface-modified dental implants, as in this study. The fact that smoking did not affect the survival rate may have been due to the short follow-up time. Many studies have reported a relationship between smoking and osseointegration failure [<xref rid="B8" ref-type="bibr">8</xref>, <xref rid="B9" ref-type="bibr">9</xref>]. Various reports have correlated smoking with poor-quality bone, type IV [<xref rid="B8" ref-type="bibr">8</xref>]. Such bone may lower the primary stability of implants. Thus, using surface-modified implants with acceptable primary stability in poorer-quality bone, such as the HA-coated implants used in this study, may be better.</p><p>We also found no statistically significant differences (<italic>P</italic> < 0.05) between prosthesis types in terms of survival rate of the implant especially between single crown and bridge restorations. Patients restored with crown-bridges had higher degrees of survival rate than those restored with crowns. A possible reason may be the occurrence of lateral or overload application [<xref rid="B25" ref-type="bibr">25</xref>]. Aglietta et al. [<xref rid="B26" ref-type="bibr">26</xref>] reported that single-unit crowns and short-span fixed dental prostheses with cantilever-supported implants did not show any difference in survival of the implant. Similarly, Naert et al. [<xref rid="B27" ref-type="bibr">27</xref>] found that the use of subsequently situated single-implant crowns to restore an edentulous space did not lead to more marginal bone loss than around splinted implants.</p><p>In conclusion, using HA-coated, short (≤8 mm), plateau-type, locking taper, screwless implants, the cumulative survival rate was 97.3% with an average follow-up of 22.83 months, a satisfactory result. However, placed region, age, and bone quality had adverse effects on survival rate. Randomized controlled clinical trials with longer follow-up should be conducted to determine the cumulative survival rate and benefits of short implants in a grander context.</p></sec></body><back><sec sec-type="conflict"><title>Conflict of Interests</title><p>The authors declare that they have no competing interests.</p></sec><ref-list><ref id="B1"><label>1</label><element-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Maló</surname><given-names>P.</given-names></name><name><surname>Nobre</surname><given-names>M.
