Abstract
Although many prosthetic materials exist for fabrication of implant-supported telescopic overdentures, available materials have not been thoroughly evaluated from a functional standpoint. This case report describes the use of polyaryletherketone (PAEK) based polymer for an implant-supported telescopic overdenture, a seldom used material in dentistry. This material is lighter than traditional materials, can accommodate changes in retentive forces, and is an easily retrievable by CAD/CAM fabrication. This case highlights the possibility of using new polymer materials for implant-supported telescopic overdentures.

Implant-supported overdenture prostheses can be divided into bar overdentures and single attachment overdentures. Single attachment elements for overdentures include single retentive anchors, single magnet anchors, and individually cast telescopic copings.<xref rid="B1" ref-type="bibr">1</xref> Among these, telescopic copings have the benefit of implant splinting found in bar overdentures and the retrievability of single attachment overdentures. However, this method is typically fabricated using gold materials, so it is not an economical treatment option. Also, if an inner crown will be worn, it is difficult to maintain appropriate retentive forces.</p><p>In this case report, a telescopic implant-supported overdenture prosthesis was made using a new material, polyaryletherketone (PAEK) based polymer (Pekkton ivory, Cendres + Métaux SA, Biel/Bienne, Switzerland). It shares benefits of typical telescopic coping, in additional to being highly economical, wear resistant, and light in weight compared to conventional implant overdenture prostheses.</p></sec><sec><title>CASE REPORT</title><p>A 79-year-old woman with mobile maxillary dentition and caries (<xref ref-type="fig" rid="F1">Fig. 1</xref>) presented to the Department of Prosthodontics at Chonnam National University Dental Hospital. After clinical and radiographic examinations, maxillary full mouth rehabilitation was planned to improve esthetics and functional oral health.</p><p>After maxillary teeth extractions and use of provisional maxillary complete denture for six months, six small diameter implant fixtures (3.0 × 10.0 mm USII, Osstem implant Co. Ltd., Seoul, Korea) were installed due to insufficient bone width (<xref ref-type="fig" rid="F2">Fig. 2A</xref>). The definitive prosthesis was planned as a telescopic overdenture using PAEK based polymer.</p><p>After a making definitive impression by polyvinylsiloxane (Honigum, DMG, Hamburg, Germany), a polymer telescopic abutment and an outer overdenture frame were fabricated with consideration of the patient's vertical dimension (<xref ref-type="fig" rid="F2">Fig. 2B</xref>, <xref ref-type="fig" rid="F2">Fig. 2C</xref>). Telescopic abutment and framework design were laid out by CAD software (Exocad dental CAD, exocad GmbH, Darmstadt, Germany). The milling machine (S1, vhf camfacture AG, Ammerbuch, Germany) made the final framework and abutment according to the design. Polymer abutment and titanium link were sandblasted by 110 um grit aluminum oxide, and bonded with primer (SR link, Ivoclar Vivadent, Schaan, Liechtenstein) and bonding agent (Multilink N, Ivoclar Vivadent, Schaan, Leichtenstein). After that, the definitive prosthesis was made by autopolymerized pour-type resin (Press LT, Retec, Rosbach, Germany) (<xref ref-type="fig" rid="F3">Fig. 3</xref>). The telescopic overdenture was fitted intraorally (<xref ref-type="fig" rid="F4">Fig. 4</xref>); the design and weight of the prosthesis were adjusted to achieve acceptable esthetics and phonetics. After 6 months, there were no problems with alveolar bone around the implant fixtures and retention of the overdenture prosthesis.</p></sec><sec sec-type="discussion"><title>DISCUSSION</title><p>A previous report<xref rid="B2" ref-type="bibr">2</xref> has discussed implant overdenture types and materials for successful treatment. However, no treatment modality meets all criteria for successful treatment, and conventional overdenture material can sometimes be limited by economic, functional, and technical considerations. Now, many new prosthetic materials are available to overcome these limitations, and as in this case, a new polymer can be used to make telescopic crowns and frameworks to obtain satisfactory results.</p><p>PAEK based polymer, Pekkton ivory, as used in this case, is a member of the high performance semi-crystalline thermoplastic resin group, recognized for its keto and ether group ratio. PAEK has good dimensional stability at high temperature, high chemical and mechanical resistance against wear, and high tensile, fatigue and flexural strength, making it an attractive material with expanded uses in medicine and dentistry.<xref rid="B3" ref-type="bibr">3</xref> However, PEEK (polyetheretherketone), a conventional PAEK-based polymer, cannot be used as a permanent material due to its relatively weak physical properties. A new material, Pekkton, is mainly composed of PEKK (polyetherketoneketone); its molecular structure has an added ketone to the structure of PEEK with and has a wide range of uses due to its amorphous and crystalline structure. PEKK reveals up to 80% greater compressive strengths than PEEK, so this polymer may be used in permanent prostheses according to the manufacturer.<xref rid="B4" ref-type="bibr">4</xref> Thus, this new polymer can be considered to have greater strength than PEEK and have greater esthetics titanium, higher resin bond strength than zirconia, and a lighter weight (1.4 g/cm<sup>3</sup>) than metal. Therefore, this material is found to be mechanically suitable for FPD frameworks, milled overdenture bars, clasps, telescopic crowns, and other applications. Despite the reportedly good bond strength, bonding between the titanium link and the telescopic abutment is still very sensitive, with the risk of fracture of the thin abutment wall due to connecting titanium link; hence more studies are needed on such cases.</p><p>The patient was monitored following delivery of the prosthesis. She reported satisfaction with its strength and esthetics, and no negative symptoms. Due to the lack of evidence on the long term retentive capabilities of this material, continuous follow up would be beneficial.</p></sec><sec sec-type="conclusions"><title>CONCLUSION</title><p>Due to its functional and economic advantages, PAEK based polymer is a good alternative material to conventional materials and methods in the fabrication of implant overdenture.</p></sec></body><back><ack><title>ACKNOWLEDGEMENTS</title><p>The authors thank the Young-Chul Cho, Vision Dental Lab, for making implant-supported telescopic overdenture using PAEK based polymer.</p></ack><ref-list><ref id="B1"><label>1</label><element-citation publication-type="book"><person-group person-group-type="author"><name><surname>Zarb</surname><given-names>GA</given-names></name><name><surname>Hobkirk</surname><given-names>J</given-names></name><name><surname>Eckert</surname><given-names>S</given-names></name><name><surname>Jacob</surname><given-names>R</given-names></name></person-group><source>Prosthodontic treatment for edentulous patients: complete dentures and implantsupported prostheses</source><edition>12th ed</edition><publisher-loc>St. Louis</publisher-loc><publisher-name>Elsevier</publisher-name><year>2004</year></element-citation></ref><ref id="B2"><label>2</label><element-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Zarb</surname><given-names>GA</given-names></name><name><surname>Schmitt</surname><given-names>A</given-names></name></person-group><article-title>The edentulous predicament.
