Several techniques have been described for use when either standard impression trays or the denture itself becomes too difficult to place and remove from the mouth.</p><p>Sectional dentures have been recommended, with the denture pieces connected by the clasps. McCord <italic>et al</italic>.[<xref ref-type="bibr" rid="ref1">1</xref>] describe a maxillary complete denture consisting of 2 pieces joined by a stainless steel rod with a diameter of 1 mm fitted behind the central incisors. Luebke <italic>et al</italic>.[<xref ref-type="bibr" rid="ref2">2</xref>] describe a sectional impression procedure for dentulous patient by using 2 plastic sectional impression trays assembled with Lego building Blocks and autopolymerizing resin.</p><p>In this article, a different design for the fabrication of maxillary and mandibular sectional trays and a foldable maxillary and mandibular complete denture is described.</p></sec><sec id="sec1-2"><title>Case Report</title><p>A 64 year old edentulous male sought treatment at the prosthodontic department in D.A.V. (C) Dental College, Yamuna Nagar, Haryana. He had a limited oral opening of about 25 mm [<xref ref-type="fig" rid="F1">Figure 1</xref>]. There was no suggestive history of smoking, alcoholism or any other systemic disease. On clinical examination, upper and lower ridges were found to be in favourable condition. Various treatment options were discussed and the patient accepted the treatment described below.</p><fig id="F1" position="float"><label>Figure 1</label><caption><p>Pre-operative photograph</p></caption><graphic xlink:href="CCD-3-349-g001"></graphic></fig></sec><sec id="sec1-3"><title>Procedure</title><p>Preliminary impressions for both dental arches were obtained with a putty silicon impression material (Imprint, 3 M ESPE, Germany) with the help of finger pressure. The impressions were poured in dental stone (Kalstone, Kalabhai Karson, Mumbai) to obtained primary cast. An autopolymerizing acrylic resin (DPI RR cold cure, DPI, India) tray was prepared on each stone cast. For each tray, 4 metal pins were attached, each 2.5 mm in diameter; two of these pins were 25 mm long and the other two were 15 mm long. In mandibular tray, the long pins were placed close to the distal end and the short pins close to the midline and in the maxillary tray, the short pins were placed over the residual ridges and the long pins close to the midline [<xref ref-type="fig" rid="F2">Figure 2</xref>].</p><fig id="F2" position="float"><label>Figure 2</label><caption><p>Sectional special tray</p></caption><graphic xlink:href="CCD-3-349-g002"></graphic></fig><p>The acrylic resin trays were lubricated with petroleum jelly, and an acrylic resin block that slid tightly on the pins was prepared. The trays were cut into two pieces with a steel disc and then joined with the acrylic resin block, which slid onto the parallel pins. The mandibular impression tray could be inserted into the patient's mouth in one piece because the acrylic resin block was elevated on the long pins and the tray could be folded in the horizontal plane.</p><p>Border moulding was alternately done for the first and second halves of the sectional trays. Impression trays were inserted into the patient's mouth in two separate pieces: Left and right and stabilized by means of the acrylic resin block. Final impressions were made by using zinc-oxide eugenol impression paste (DPI impression paste, DPI, India) in sectional trays, which were stabilized intraorally with acrylic resin block. After the impression paste set, the acrylic resin blocks were detached in the mouth, and the right and left pieces were removed separately by fracturing the impression material. The acrylic resin blocks were carefully joined out of the mouth and after it was determined that the fracture line joined smoothly, dental stone was poured [<xref ref-type="fig" rid="F3">Figure 3</xref>].</p><fig id="F3" position="float"><label>Figure 3</label><caption><p>Final impression in sectional tray</p></caption><graphic xlink:href="CCD-3-349-g003"></graphic></fig><p>The maxillary and mandibular denture bases were prepared in two pieces: right and left. These pieces were joined by overlapping one on the other by 2 mm in the midline. A stainless steel hinge was fitted with autopolymerizing acrylic resin in the centre of the axis connecting the denture bases [<xref ref-type="fig" rid="F4">Figure 4</xref>].</p><fig id="F4" position="float"><label>Figure 4</label><caption><p>Temporary denture base with hinge</p></caption><graphic xlink:href="CCD-3-349-g004"></graphic></fig><p>Jaw relation record was obtained with the use of occlusion rims oriented to the established vertical dimension of occlusion, the anatomic occlusal plane, and the patient's centric relation. The try-in sectional denture was evaluated to verify jaw relations and tooth arrangement.</p><p>Heat cure acrylization was carried out alternately for right and left halves of the denture bases and to prevent flow of resin into the connecting area, silicone impression material was placed into the gap in the hinge design. The denture was deflasked, trimmed and polished [<xref ref-type="fig" rid="F5">Figure 5</xref>].</p><fig id="F5" position="float"><label>Figure 5</label><caption><p>Foldable complete denture</p></caption><graphic xlink:href="CCD-3-349-g005"></graphic></fig><p>Home care instruction (oral hygiene instruction, insertion and removal of prosthesis) were imparted to the patient and routine follow-up appointments were scheduled.</p></sec><sec sec-type="discussion" id="sec1-4"><title>Discussion</title><p>Many authors have advised sectional custom trays and collapsible denture systems with complicated attachment devices, e.g. locking levers (Various pins, bolts, and Lego pieces),[<xref ref-type="bibr" rid="ref3">3</xref>] hinges,[<xref ref-type="bibr" rid="ref4">4</xref><xref ref-type="bibr" rid="ref5">5</xref>] orthodontic expansion screws, magnet systems, etc. For the patient described here, 4 parallel pins and an acrylic resin block fitted on these pins serve as a locking mechanism.</p><p>The use of different size pins in the mandibular impression tray made it possible for the tray to be folded in the horizontal plane and inserted in one piece, facilitating impression procedure. It was believed that the cross section of the mandibular impression paste was not wide enough in the midline and that this would negatively affect the stability of the right and the left tray pieces. Thus the pins on the mandibular tray were arranged in 2 different planes and the resin block fitted on these pins ensured the proper approximation of two halves of the tray.</p><p>When the oral opening is limited, joining the pieces of a sectional denture base intraorally may be problematic. For this reason, we preferred to fabricate the collapsible (foldable) design of maxillary and mandibular complete denture.</p></sec><sec id="sec1-5"><title>Summary and Conclusion</title><p>Severe reduction of oral opening renders access to the oral cavity difficult for dental procedures. This report describes the impression procedure for a patient with restricted mouth opening using a sectional impression tray and fabrication of sectional maxillary and mandibular denture. <xref ref-type="fig" rid="F6">Figure 6</xref> presents a patient who has been wearing such appliances successfully for the past 2 years.</p><fig id="F6" position="float"><label>Figure 6</label><caption><p>Post-operative photograph</p></caption><graphic xlink:href="CCD-3-349-g006"></graphic></fig></sec></body><back><ack><title>Acknowledgment</title><p>I would like to acknowledge with sincere gratitude, the effort put into this manuscript by Prof.(Dr.) Aman Arora M.D.S.</p></ack><fn-group><fn fn-type="supported-by"><p><bold>Source of Support:</bold> Nil,</p></fn><fn fn-type="conflict"><p><bold>Conflict of Interest:</bold> None declared</p></fn></fn-group><ref-list><ref id="ref1"><label>1</label><element-citation publication-type="journal"><person-group person-group-type="author"><name><surname>McCord</surname><given-names>JF</given-names></name><name><surname>Tyson</surname><given-names>KW</given-names></name><name><surname>Blair</surname><given-names>IS</given-names></name></person-group><article-title>A sectional complete denture for a patient with microstomia</article-title><source>J Prosthet Dent</source><year>1989</year><volume>61</volume><fpage>645</fpage><lpage>7</lpage><pub-id pub-id-type="pmid">2657017</pub-id></element-citation></ref><ref id="ref2"><label>2</label><element-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Luebke</surname><given-names>RJ</given-names></name></person-group><article-title>Sectional impression tray for patient with constricted oral opening</article-title><source>J Prosthet Dent</source><year>1984</year><volume>52</volume><fpage>135</fpage><lpage>7</lpage><pub-id pub-id-type="pmid">6379156</pub-id></element-citation></ref><ref id="ref3"><label>3</label><element-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Dhanasomboon</surname><given-names>S</given-names></name><name><surname>Kiatsiriroj</surname><given-names>K</given-names></name></person-group><article-title>Impression procedure for a progressive sclerosis patient: A clinical report</article-title><source>J Prosthet Dent</source><year>2000</year><volume>83</volume><fpage>279</fpage><lpage>82</lpage><pub-id pub-id-type="pmid">10709034</pub-id></element-citation></ref><ref id="ref4"><label>4</label><element-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Cura</surname><given-names>C</given-names></name><name><surname>Cotert</surname><given-names>HS</given-names></name><name><surname>User</surname><given-names>A</given-names></name></person-group><article-title>Fabrication of a sectional impression tray and sectional complete denture for a patient with microstomia and trismus: A clinical report</article-title><source>J Prosthet Dent</source><year>2003</year><volume>89</volume><fpage>540</fpage><lpage>3</lpage><pub-id pub-id-type="pmid">12815346</pub-id></element-citation></ref><ref id="ref5"><label>5</label><element-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Baker</surname><given-names>PS</given-names></name><name><surname>Brandt</surname><given-names>RL</given-names></name><name><surname>Boyajian</surname><given-names>G</given-names></name></person-group><article-title>Impression procedure for patients with severely limited mouth opening</article-title><source>J Prosthet Dent</source><year>2000</year><volume>84</volume><fpage>241</fpage><lpage>4</lpage><pub-id pub-id-type="pmid">10946347</pub-id></element-citation></ref></ref-list></back></pmc></record>Pour manipuler ce document sous Unix (Dilib)
