<title>Introduction</title>
<p>The osseointegrated implants are widely researched and safely applied in modern dentistry <xref rid="bib0005" ref-type="bibr">[1]</xref>
. The main goal of this technique is to increase the stability of prosthesis during the masticatory function, improving the quality of life of the patient <xref rid="bib0010" ref-type="bibr">[2]</xref>
.</p>
<p>The upper jaw region possesses a trabecular bone (type 3 and 4) and some critical areas such as the nasal cavity and maxillary sinus, which could complicate the installation of parallel implants with adequate height <xref rid="bib0005 bib0015 bib0020 bib0025" ref-type="bibr">[1,3–5]</xref>
. Additionally, the anterior region has a thin bone cortical from both buccal and palatal sides <xref rid="bib0030" ref-type="bibr">[6]</xref>
.</p>
<p>When this occurs, tilted dental implants may be installed to guarantee proper retention, as well as the preservation of important anatomical structures <xref rid="bib0005 bib0010 bib0035" ref-type="bibr">[1,2,7]</xref>
. The aim of the tilting is to improve the implant positioning, so that it is placed in the area that presents the greatest amount of bone <xref rid="bib0025 bib0040" ref-type="bibr">[5,8]</xref>
, since more contact with trabecular bone allows a better implant anchorage and permits the utilization of longer implants <xref rid="bib0010 bib0020 bib0045 bib0050" ref-type="bibr">[2,4,9,10]</xref>
. Also, it is a simpler and less invasive option than bone grafting surgeries <xref rid="bib0005 bib0015 bib0020 bib0035" ref-type="bibr">[1,3,4,7]</xref>
.</p>
<p>The dynamic universal castable long abutment (UCLA) is an alternative option of abutment used to rectify the implant tilting. That UCLA allows the correction of the implant emergence profile up to 20°, turning it to a favorable position <xref rid="bib0055" ref-type="bibr">[11]</xref>
.</p>
<p>Even though single tilted implants are frequently used at dental practice, few cases report their installation on anterior regions describing the whole process from the surgical procedure until the crown sets in <xref rid="bib0060" ref-type="bibr">[12]</xref>
. The aim of this paper was to present a rehabilitation of a patient with a dynamic universal castable long abutment (UCLA) for a single tilted implant in the anterior maxillary area.</p>

<title>Case presentation</title>
<p>A 57-year-old patient came to the Department of Dental Material and Prosthodontics of the Aracatuba Dental School, complaining of a fracture of the dental element 22 (<xref rid="fig0005" ref-type="fig">Fig. 1</xref>
). This element was previously restored with a single partial fixed prosthesis with a metallic core. The patient presented good general health. The clinical exam indicated a lack of gingival smile, a class IV fracture at the incisal portion of the 11 and a vertical root fracture of the 22. Due to this fracture, tooth extraction was indicated. The patient assigned an informed consent for proposed oral rehabilitation.</p>
<p>The treatment plan established was to replace the fractured tooth with a single implant. After the extraction, it was verified that the socket buccal wall thickness was unsatisfactory, so the implant was installed with an inclination of 20° to the palate (<xref rid="fig0010" ref-type="fig">Fig. 2</xref>
). The surgical procedure was a two-stage protocol, and three months after the extraction, a dental implant (external hexagon 3.75 mm diameter and 11.5 mm length; Osteofit, Campo Largo, Paraná, Brazil) was placed and a 40 N torque was applied for primary stability. The top of the implant was at crestal bone level. A provisional adhesive prosthesis was manufactured prior to the surgery and installed after the implant placement. Two weeks after the surgery, the sutures were removed.</p>
<p>After a six-month healing period, osseointegration was assessed through a radiographic analysis. No radiolucent line was observed around the implant. Then, the implant site was reopened and the healing cap was placed (<xref rid="fig0015" ref-type="fig">Fig. 3</xref>
). After the tissue remodeling, the squared transfer was positioned and had its setting to the implant confirmed through a radiograph. Then an open tray impression was made with addition silicon Express (3M ESPE, Sumaré, São Paulo, Brazil), alongside with the impression of the opposed arch.</p>
<p>The depth and thickness of the gingival tissue was evaluated to confirm that the abutment metal collar would not be visible. The depth of the gingival sulcus was 2 mm. A chrome–cobalt 20° UCLA was screwed to the implant (Mangran Internacional, Curitiba, Parana, Brazil) to correct its tilting (<xref rid="fig0020 fig0025" ref-type="fig">Figs. 4 and 5</xref>
).</p>
<p>After the metal casting (<xref rid="fig0030 fig0035" ref-type="fig">Figs. 6 and 7</xref>
), the setting of the coping was assessed through radiographs so the ceramic cover could be applied (<xref rid="fig0040" ref-type="fig">Fig. 8</xref>
). On the next session, a prosthesis try-in was performed, the occlusal and proximal contacts were evaluated with a carbon paper (Accufilm II, Parkell, New York, USA) and, with the patient’s informed consent, the prosthesis was finalized.</p>
<p>At the installation moment, the dental contacts were once again verified, as was the radiographic aspect (<xref rid="fig0045" ref-type="fig">Fig. 9</xref>
), a 20 N torque was applied to the abutment screw and, in a different session, the screw access hole was covered with a resin composite. The patient was pleased with the final clinical aspect (<xref rid="fig0050 fig0055" ref-type="fig">Figs. 10 and 11</xref>
).</p>
<p>After a twenty-month follow-up (<xref rid="fig0060" ref-type="fig">Fig. 12</xref>
), complications such as loosening or fracture of the prosthetic screw and implant fracture were not observed <xref rid="bib0065" ref-type="bibr">[13]</xref>
. Additionally, no bone loss was observed in the peri-implant bone area. The patient is pleased with the rehabilitation.</p>
<p>The 20° UCLA used in this case presents as an advantage the possibility of correction of the implant tilting in a screwed prosthesis whether a cemented one, in fewer clinical steps. Additionally, as the prosthesis is manufactured with the UCLA, only one screw is necessary in the assembly, between the abutment and the implant. However, there is a contraindication in cases of excessive load, especially in patients with parafunctional habits.</p>

<sec sec-type="discussion" id="sec0015"><label>3</label>
<title>Discussion</title>
<p>Some clinical reports presented acceptable success rates with the installation of tilted implants. These implants minimize the need of bone grafting surgeries decreasing the procedure length and complexity thus increasing the amount of patients willing to undertake rehabilitations with such procedure <xref rid="bib0035" ref-type="bibr">[7]</xref>
.</p>
<p>Tilted implants are mostly used in posterior regions, in cases of atrophic maxillae where the proximity to the sinus may restrict the amount of bone available to the anchorage of dental implants <xref rid="bib0045" ref-type="bibr">[9]</xref>
. However, some authors also report successful installation of tilted implants in anterior regions with no compromise of an aesthetic result <xref rid="bib0060" ref-type="bibr">[12]</xref>
.</p>
<p>There is no evidence that contraindicates the placement of tilted implants, no significant difference was noticed when evaluating the bone loss around axial and tilted implants <xref rid="bib0050 bib0070 bib0075" ref-type="bibr">[10,14,15]</xref>
. In addition, the complications reported are very similar to the conventional implants <xref rid="bib0050" ref-type="bibr">[10]</xref>
. Some of the complications reported were mucositis, sinus infection and periimplantitis <xref rid="bib0030 bib0050" ref-type="bibr">[6,10]</xref>
. In this clinical report no bone loss or complications were observed during the 20-month follow up period.</p>
<p>Bateli et al. <xref rid="bib0035" ref-type="bibr">[7]</xref>
 highlighted the importance of a tridimensional exam for the correct placement of angled implants. The authors affirmed that the inclination of dental implants prevent bone grafting procedures and should be used as often as possible.</p>
<p>The dynamic UCLA is a viable solution for cases in which the aesthetics is compromised during a prosthetic rehabilitation. The dynamic UCLA avoid possible discomfort that other systems may have, such as excessive buccal volume of the prosthesis infrastructure, depending on the planning and positioning of the implant. The dynamic UCLA handling is basically laboratorial. By means of an indexer, the dentist and dental technician select the best positioning and tilting of the system, to project a prosthesis that is both functional and aesthetic. This is possible because of the total freedom that the dynamic UCLA provides, with its characteristics of rotating on its own axis by 360° and tilting from 0° to 28° <xref rid="bib0055" ref-type="bibr">[11]</xref>
.</p>
<p>The clinical effect is: the dynamic UCLA provided movement freedom, pinpoint accuracy to the desired angle, gain in aesthetics and function, treatment agility and cost reduction.</p>

<title>Conclusions</title>
<p>The use of a dynamic UCLA to correct tilted implants is a viable treatment option for patients with atrophic maxillae, and may be faster and less invasive than bone grafts.<list list-type="simple"><list-item id="lsti0020"><label>-</label>
<p>The dynamic UCLA allows dentists to rectify up to 20° of the implant emergence profile, which ensure an aesthetic result.</p>
</list-item>
<list-item id="lsti0025"><label>-</label>
<p>This treatment can result in high levels of patient satisfaction, with reestablishment of function and aesthetics and longevity of prosthetic rehabilitation.</p>
