Introduction</title><p>For partially or totally edentulous patients in Korea and worldwide, dental implants have been widely used as restorative treatment for the loss of mastication ability, esthetics, and phonetic function. Studies on the osseointegration of implants with bone, biodynamics, and other diverse areas have been actively conducted. Nevertheless, the success rate of implants placed in the oral cavity using developed techniques is generally 93%<xref ref-type="bibr" rid="B1">1</xref>, although it varies among studies. Causes of implant failure are osseointegration failure, implant placement at the wrong site, lesion around implants, biodynamic failure, etc.<xref ref-type="bibr" rid="B1">1</xref>,<xref ref-type="bibr" rid="B2">2</xref></p><p>Damage to natural teeth adjacent to implants during implant placement may wield adverse effects on adjacent teeth and may facilitate implant failure; thus emphasizing the importance of its treatments and prevention. Its primary causes include: implant placement in erroneous sites and at an improper placement angle; errors in determining the distance to the adjacent teeth, and; use of excessively wide-type fixtures due to the insufficient height of the residual alveolar bone. Nonetheless, depending on the distance of the fixture to the adjacent teeth, symptoms may be present or absent, and opinions regarding these differences are not consistent between investigators.</p><p>Therefore, in these case reports, we discuss the overall causes, symptoms, treatments, and strategies for the prevention of damage to adjacent teeth, which may occur during implant placement.</p></sec><sec><title>II. Cases Report</title><sec><title>1. Case 1</title><p>A 63-year-old male patient visited our hospital with chief complaint of uncomfortable current maxillary removable partial denture. There were no special findings in his medical history. Including the immediate implant placement after the extraction of tooth #13, implants were placed in 6 areas (#17, #14, #13, #11, #21, and #27). On the postsurgical panoramic radiographs and computed tomography images, the implant (DAS, 3.8×10 mm; DAS Tech, Gwangju, Korea) placed in #21 was observed to be tilted to the distal side and positioned closely to the adjacent #22.(<xref ref-type="fig" rid="F1">Figs. 1. A, 1. B</xref>) The fixture did not affect the adjacent periodontal ligament space, however. The implant stability quotient (ISQ) using Osstell Mentor (Integration Diagnostics AB, Göteborg, Sweden) was 67. #22 did not show specific clinical and radiological findings.</p><p>The follow-up radiographs taken 6 and 18 months after surgery showed no extraordinary findings in the periradicular area of the natural adjacent tooth.(<xref ref-type="fig" rid="F1">Figs. 1. C, 1. D</xref>)</p></sec><sec><title>2. Case 2</title><p>A 55-year-old male patient visited our hospital primarily requiring repair of the implant placed in the missing maxillary molar area. According to his medical history, he had diabetes, which was controlled with medication. Clinical and radiological tests revealed the loss of several maxillary molars (#16, 17, 25, 26, and 27). The left maxillary first premolar (#24) showed a residual root with periradicular inflammation. On the day of the visit, the root was extracted. Because of the patient's personal situation, 18 months passed before an implant was placed in the corresponding area (Astra, 3.5×9.0 mm; OsseoSpeed TX, Astra Tech AB, Mölndal, Sweden), and allogenic bone graft (Allomatrix; Wright Medical Technology Inc., Arlington, TN, USA) was performed simultaneously. ISQ using Osstell Mentor was 72. Nonetheless, the fixture was observed to be located very close to the adjacent tooth (#23).(<xref ref-type="fig" rid="F2">Figs. 2. A-2. C</xref>) In addition, radiolucency was noted in the periradicular area of the fixture. The radiographs taken 14 months later showed that its size was not changed.(<xref ref-type="fig" rid="F2">Figs. 2. D, 2. E</xref>) There were no specific clinical findings in the adjacent natural teeth. After 1 year, the Periotest value (PTV) using PerioTest C (Medizintechnik Gulden, Hessen, Germany) was -4.</p></sec><sec><title>3. Case 3</title><p>An implant was placed in a 62-year-old female patient due to the loss of the left maxillary second molar (#27) (Biohorizon, 4.6×10.5 mm; Biohorizons Implant Systems Inc., Bir mingham, AL, USA). PTV was 7, which was slightly low. In addition, the postsurgical radiographs showed that, due to the dilaceration of the adjacent natural tooth, the fixture was located near the left maxillary first molar.(<xref ref-type="fig" rid="F3">Figs. 3. A-3. C</xref>) A second surgery was performed after 9 months. PTV was -6 (PerioTest C), and ISQ was 84, which were good levels. One year after surgery, endodontic treatments were performed to resolve hypersensitivity symptoms caused by the fall-out of the prosthesis in the mesial area of the adjacent natural tooth (#26) but were not associated with a fixture placed nearby. The follow-up radiographs did not show special findings.(<xref ref-type="fig" rid="F3">Figs. 3. D, 3. E</xref>)</p></sec></sec><sec><title>III. Discussion</title><p>As the placement of implant prostheses becomes more common in partially edentulous patients, damage to the adjacent teeth due to placement in wide areas must be considered a serious potential side effect.</p><p>Causes of such damage include errors in determining the distance to the adjacent teeth by radiological tests, erroneous placement and angle<xref ref-type="bibr" rid="B3">3</xref>, direct damage due to the use of excessively wide fixtures owing to the insufficient height of the residual alveolar bone, and indirect damage caused by the generation of excessive heat during osteotomy<xref ref-type="bibr" rid="B4">4</xref>. Consequently, due to the invasion of the periodontal ligament space, blood supply is impaired, resulting in the loss of viability of the endodontium<xref ref-type="bibr" rid="B5">5</xref>; hence the higher incidence rate of periapical lesions. In addition, the mobility of the tooth may increase<xref ref-type="bibr" rid="B6">6</xref>. The damaged natural tooth may require endodontic treatments or apicoectomy; if the symptoms persist, tooth extraction may be necessary<xref ref-type="bibr" rid="B7">7</xref>. Additionally, if the integration of implants and the alveolar bone are decreased due to apical inflammation, the bone defect areas may be restored, and the position stability of the fixture may be raised with guided bone regeneration using a flap<xref ref-type="bibr" rid="B8">8</xref>,<xref ref-type="bibr" rid="B9">9</xref>. If the prognosis is poor, and the symptoms persist, however, the removal of the fixture may ultimately be necessary due to a reduction in the initial stability of implants<xref ref-type="bibr" rid="B10">10</xref>. Moreover, this problem may occur not only with simple implants but also with the placement of orthodontic mini-screws.</p><p>To prevent the injury of the natural tooth by implants, the slope of the adjacent teeth should be measured accurately using radiographs prior to surgery, and the appropriate placement angle should be determined. This angle is pertinent to the postsurgical direction of mastication, and it is an important factor for the success of the prosthesis. In addition, the presence or absence of dilaceration of the root should be determined<xref ref-type="bibr" rid="B4">4</xref>. Finally, the thickness of the alveolar bone surrounding the fixture should be at least 1.0 mm<xref ref-type="bibr" rid="B1">1</xref>. This value can reach 1.5 mm depending on the study<xref ref-type="bibr" rid="B3">3</xref>. If an implant fixture is located closer than this range, depending on the biological width or stress, the resorption of the bone between the adjacent tooth and implants may be induced<xref ref-type="bibr" rid="B11">11</xref>. Errors in detecting this phenomenon can be prevented with the use of the parallel technique when taking intraoral standard images. In panoramic images, a distortion of approximately 25% is present, increasing the possibility of errors; thus, presurgical computed tomography may help ensure accurate diagnosis<xref ref-type="bibr" rid="B12">12</xref>,<xref ref-type="bibr" rid="B13">13</xref>. In addition, establishing a placement guide is helpful by preparing a surgical stent using a preliminary impression<xref ref-type="bibr" rid="B14">14</xref>. During surgery, the equilibrium must be assessed by inserting a guide pin after osteotomy. In placement, to prevent the generation of excessive heat, implants wherein the temperature does not rise above 33.8℃ during a maximum of 5 seconds of drilling should be ensured.</p><p>In our 3 cases, the possibility of root injury was increased by the erroneous position and angle during implant placement and movement toward the natural tooth. Nonetheless, specific symptoms of the corresponding implant and the adjacent natural teeth were not observed during the follow-up period. According to other documents, injury of the teeth adjacent to implants may result in poor implant success rate and difficulty in maintaining the viability of the endodontium of the natural tooth. Not all cases with injured natural tooth have increase mobility, loss of viability of the endodontium, or periapical lesions, but these manifestations can be prevented by accurate diagnosis using presurgical radiographs, appropriate placement angle, reduction of generation of heat during implant placement, and appropriate postsurgical treatments through continuous follow-ups.</p></sec></body><back><ref-list><ref id="B1"><label>1</label><element-citation publication-type="journal"><person-group
