Abstract
The modified lateral-screw-retained implant prosthesis (LSP) is designed to combine the advantages of screw- and cement-retained implant prostheses. This retrospective study evaluated the mechanical and biological complication rates of implant-supported single crowns (ISSCs) inserted with the modified LSP in the posterior region, and determined how these complication rates are affected by clinical factors.
Mechanical complications (i.e., lateral screw loosening [LSL], abutment screw loosening, lateral screw fracture, and ceramic fracture) and biological complications (i.e., peri-implant mucositis [PM] and peri-implantitis) were identified from the patients' treatment records, clinical photographs, periapical radiographs, panoramic radiographs, and clinical indices. The correlations between complication rates and the following clinical factors were determined: gender, age, position in the jaw, placement location, functional duration, clinical crown-to-implant length ratio, crown height space, and the use of a submerged or nonsubmerged placement procedure.
Mechanical and biological complications were present in 25 of 73 ISSCs with the modified LSP. LSL (n=11) and PM (n=11) were the most common complications. The incidence of mechanical complications was significantly related to gender (
Within the limitations of this study, the incidence of mechanical and biological complications in the posterior region was similar for both modified LSP and conventional implant prosthetic systems. In addition, the modified LSP is amenable to maintenance care, which facilitates the prevention and treatment of mechanical and biological complications.

This retrospective study evaluated the mechanical and biological complication rates of implant-supported single crowns (ISSCs) inserted with the modified LSP in the posterior region, and determined how these complication rates are affected by clinical factors.</p></sec><sec><title>MATERIALS AND METHODS</title><p>Mechanical complications (i.e., lateral screw loosening [LSL], abutment screw loosening, lateral screw fracture, and ceramic fracture) and biological complications (i.e., peri-implant mucositis [PM] and peri-implantitis) were identified from the patients' treatment records, clinical photographs, periapical radiographs, panoramic radiographs, and clinical indices. The correlations between complication rates and the following clinical factors were determined: gender, age, position in the jaw, placement location, functional duration, clinical crown-to-implant length ratio, crown height space, and the use of a submerged or nonsubmerged placement procedure.</p></sec><sec><title>RESULTS</title><p>Mechanical and biological complications were present in 25 of 73 ISSCs with the modified LSP. LSL (n=11) and PM (n=11) were the most common complications. The incidence of mechanical complications was significantly related to gender (<italic>P</italic>=.018). The other clinical factors were not significantly associated with mechanical and biological complication rates.</p></sec><sec><title>CONCLUSION</title><p>Within the limitations of this study, the incidence of mechanical and biological complications in the posterior region was similar for both modified LSP and conventional implant prosthetic systems. In addition, the modified LSP is amenable to maintenance care, which facilitates the prevention and treatment of mechanical and biological complications.</p></sec></abstract><kwd-group><kwd>Dental implant</kwd><kwd>Dental prosthesis design</kwd><kwd>Peri-implantitis</kwd><kwd>Prosthesis failure</kwd><kwd>Single-tooth implant</kwd></kwd-group><funding-group><award-group><funding-source country="KR"><institution-wrap><institution>National Health Insurance Service Ilsan Hospital</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><floats-group><fig id="F1" orientation="portrait" position="float"><label>Fig. 1</label><caption><title>Three-dimensional view (A), cross-sectional view and photograph (B) of the modified lateral-screw-retained implant prosthesis (LSP).

The lateral screw can be tightened if necessary using a lateral screwdriver with a contra-angle attachment. The implant abutment/crown is manually tightened to a torque of 5-10 Ncm. (B) Since the lateral screw is designed for use with a lateral screwdriver and a contra-angle attachment, it is easily managed within the oral cavity.</title></caption><graphic xlink:href="jap-8-150-g003"></graphic></fig><fig id="F4" orientation="portrait" position="float"><label>Fig. 4</label><caption><title>Frequency distribution of implants according to their position in the jaw and the complication rates of the implant-supported single crowns (ISSCs) with the modified LSP in the posterior region.</title><p>ASL, abutment screw loosening; LSF, lateral screw fracture; CF, ceramic fracture; PM, peri-implant mucositis; PI, peri-implantitis.</p></caption><graphic xlink:href="jap-8-150-g004"></graphic></fig><fig id="F5" orientation="portrait" position="float"><label>Fig. 5</label><caption><title>Incidence of mechanical and biological complications according to the duration of functional loading.</title></caption><graphic xlink:href="jap-8-150-g005"></graphic></fig><table-wrap id="T1" orientation="portrait" position="float"><label>Table 1</label><caption><title>Characteristics of the study populations of patients and implants for implant-supported single crowns (ISSCs) with the modified lateral-screw-retained implant prosthesis (LSP)</title></caption><alternatives><graphic xlink:href="jap-8-150-i001"></graphic><table frame="hsides" rules="rows"><col width="60.15%" span="1"></col><col width="39.85%" span="1"></col><thead><tr><th valign="top" align="left" rowspan="1" colspan="1">Patients, n = 70</th><th valign="top" align="center" rowspan="1" colspan="1">Value</th></tr></thead><tbody><tr><td valign="top" align="left" rowspan="1" colspan="1">Gender</td><td valign="top" align="center" rowspan="1" colspan="1"></td></tr><tr><td valign="top" align="left" rowspan="1" colspan="1"> Male</td><td valign="top" align="center" rowspan="1" colspan="1">37 (52.9)</td></tr><tr><td valign="top" align="left" rowspan="1" colspan="1"> Female</td><td valign="top" align="center" rowspan="1" colspan="1">33 (47.1)</td></tr><tr><td valign="top" align="left" rowspan="1" colspan="1">Age, mean (range)</td><td valign="top" align="center" rowspan="1" colspan="1">54.9 years (25 -
