A Case of Aneurysmal Sac Enlargement after EVAR Treated with a Relining Technique

A survey of impression materials and techniques in fixed partial dentures among general dental practitioners and prosthodontists in India

Background: Replacement of missing tooth plays an important role in patient’s comfort and self-esteem. Aims and Objectives: The aims of this study were to investigate the most commonly used impression materials and techniques practiced for crowns and bridgework by prosthodontists and general dental practitioners compared to the theoretical methods suggested in the literature and to determine the clinical factors that might influence the decision-making process for the selection of impression materials and techniques. Materials and Methods: Pre-tested and pre-validated structured and closed-ended anonymous questionnaire was shared with general dental practitioners and prosthodontists. Results: Most of the prosthodontists use diagnostic impression compared to general dental practitioners (P<0.01). Full-arch tray was used by general dental practitioners significantly more frequently compared to prosthodontists (P<0.01) for single anterior, single posterior, anterior, and posterior bridge preparations. Alginate hydrocolloid was used by general dental practitioners significantly more than prosthodontists (P<0.05); however, addition silicone and condensation silicone were used by prosthodontists significantly more than general dental practitioners (P<0.05). For the impression technique followed in case of using elastomeric impression materials, the prosthodontists used the two-step putty reline technique with spacer more commonly, while general dental practitioners used the multiple mix technique (P<0.01). For the use of provisional restoration for single tooth crowns and for all the bridges, prosthodontists used provisional restoration in significantly higher proportion as compared to general dental practitioners (P<0.01). Conclusion: According to our study compared to general dental practitioners, practices of the prosthodontists regarding use of fixed partial denture is more in line with the current global trend.

Quality of Life, Satisfaction, Occlusal Force, and Halitosis after Direct and Indirect Relining of Inferior Complete Dentures.

Objective The aim of this study was to compare the direct relining technique with the indirect relining technique in relation to quality of life, satisfaction with the relining, occlusal force, and halitosis of users of acrylic complete dentures. Materials and Methods Twenty bimaxillary edentulous individuals were selected. They had to use the same pair of complete dentures for a minimum of 1 year and a maximum of 5 years. The subjects were randomly divided in groups of direct relining and indirect relining of the inferior denture ( n = 10). Both groups received the same silicone-based relining. The clinical tests verified the quality of life (Oral Health Impact Profile in edentulous individuals), the satisfaction with the relining, the occlusal force, and halitosis. The tests (halitosis and occlusal force) were performed initially (before the relining), immediately after the relining, and 30, 60, 90, and 180 days after the relining. The questionnaires (quality of life and satisfaction with the relining) were performed initially (before the relining), and 30, 60, 90, and 180 days after the relining. Statistical Analysis Analysis of variance and the Tukey test were used ( p < 0.05). Results There was no statistical difference comparing the two techniques in all the evaluations ( p < 0.05). There was a significant statistical difference for the factor of time in all clinical tests for each relining technique ( p < 0.05). The quality of life and satisfaction with the relining increased significantly 30 days after the relining when compared with the initial time point, for both techniques ( p < 0.05). The occlusal force increased significantly after 90 and 180 days when compared with the initial time point, for both techniques ( p < 0.05). Halitosis decreased significantly immediately after the relining when compared with the initial time point, for both techniques ( p < 0.05). Conclusion Independent of the relining technique used, there was an increase in the quality of life, satisfaction with the relining, and occlusal force, as well as a reduction in the level of halitosis. Both techniques generated similar results and therefore can be options in clinical practice.

Endovascular Relining of Chronically Occluded Infrainguinal Venous Bypass Grafts

Treatment of chronically occluded infrainguinal venous bypass grafts in patients presenting with recurrent chronic limb threatening limb ischemia (CLTI) represent a clinical challenge. Recent case reports have suggested the use of endovascular recanalization techniques without preceding thrombolysis. This study assesses feasibility and mid-term outcomes of this technique. A retrospective review of 5 consecutive patients (3 men, 2 women, mean age 70 ± 5 years) presenting with chronic venous bypass graft occlusion and recurrence of CLTI during 1 year was performed. Patients were treated with relining of the bypass grafts. Patients were followed up at median 26 (6-36) months. All patients were treated successfully with restoration of flow in the grafts using recanalization and relining technique without thrombolysis. In 4 patients, a Viabahn stentgraft (SG) was used with the addition of interwoven nitinol stents (INS) in 3. In 1 patient, the graft was treated with INS without the addition of a stentgraft. No peripheral embolization was encountered during the procedures. One patient occluded the relined grafts after 6 months. The remaining 4 grafts were all patent at 24-month follow-up. A total of 6 reinterventions (in 3 patients) were performed to reach 80% secondary patency. This case series demonstrate feasibility and promising mid-term results, from relining of chronically occluded infra-inguinal venous bypass grafts using stent grafts, interwoven and bare-metal stents without preceding thrombolysis. The technique could be an alternative treatment option in the treatment of these challenging cases.

Relining effects on the push-out shear bond strength of glass fiber posts

Abstract Introduction The correct use of glass fiber posts in endodontically treated teeth is essential for the clinical success of restorative treatment. Objective This study evaluated the push-out shear bond strength of relined (R) or non-relined (NR) glass fiber posts, cemented with self-adhesive resin cement [RelyXTM U100 (U100)] and conventional resin cement [RelyXTM ARC (ARC)]. Material and method Sixty human single-rooted teeth were endodontically treated and divided into ARC-NR; U100-NR; ARC-R; U100-R groups. The teeth were sectioned into cervical, middle and apical thirds, and subjected to the push-out test. Bond strength was analyzed by the Friedman test; cement and post types were compared by the Mann Whitney test. The pattern of failures was evaluated with digital camera through images at 200x magnification, and was classified as adhesive (at the cement/dentin or cement/post interface), cohesive (cement or post), and mixed failures. Result In ARC-NR, bond strength values were higher in the cervical third; in U100-NR and ARC-R they were similar between the thirds. In U100-R, in the cervical and middle thirds the bond strength values were similar, and there was lower value in the apical third. For non-relined glass fiber posts, the highest mean bond strength values were observed with self-adhesive resin cement. Whereas, relined posts cemented with conventional resin cement had stronger cement layer in comparison with non-relined fiber posts. Conclusion The post relining technique was efficient in ARC-R. ARC-NR and U100-R showed improved bond strength in the cervical region of canal walls. The main failures were adhesive at the cement-post interface.

Dimensional Accuracy of Multiple Pour Cast from Different Elastomer Impression Techniques

ABSTRACT Context The elastomeric impression material is the most widely used impression material in contemporary dental practice; their accuracy is critical for the outcome of indirect restorations. The accurate duplicate cast obtained from single impression reduces the professional clinical time, patient inconvenience, and extra material cost. Aim To compare the accuracy of the cast obtained from various impression methods utilizing elastomer impression materials. Materials and methods The stainless steel working cast model assembly consisting of two abutments and one pontic area was fabricated. Two sets of six each custom aluminum trays were fabricated, with 5 mm spacer and 2 mm space. The impression methods evaluated in the study were additional silicone putty reline (two step), heavy-light body (one step), monophase (one step), and polyether (one step). Type IV gypsum casts were poured at intervals of 1, 12, 24, and 48 hours. The resultant cast was measured with a traveling microscope for comparative dimensional accuracy. The data obtained were subjected to analysis of variance test at significance level &lt;0.05. Results The die obtained from putty reline two-step impression techniques had the percentage of variation for the height -0.36 to -0.97% with 0.40 to 0.90% increase in diameter. One-step heavy-light body impression dies recorded the increased width by 0.50 to 0.80% and height reduced by - 0.73 to -1.21%. The resultant dies from additional silicone monophase impressions had a percentage of variation for width 1.20% and height by-1.34%. The similar value for width and height for polyether was -1.46% and -1.30% respectively. Conclusion Putty reline technique dies had better dimensional accuracy after repeated pour followed by dies from heavy-light body additional silicone impression. Key message The multiple pour cast from putty reline elastomeric impressions is clinically acceptable, while cast from polyether was smaller in dimension.

Endotension-related aortic sac rupture treated by endograft relining

Endovascular aortic aneurysm repair is an effective alternative to open surgical repair in high risk patient. Endotension is an unpredictable late and rare complication of EVAR. Clinical significance and choice of technique for treatment are controversial. At present, there are no cases of endotension-related aneurysmal sac rupture reported in literature, altough it is frequently associated with late surgical conversion. In this case report is described a case of a patient treated with a first generation Gore Excluder(TM) endograft for abdominal aortic aneurysm, with late aneurysmal sac enlargement without evidence of endoleak and subsequent contained rupture without anemia and shock. We have successfully treated the patient by endovascular procedure, through bilateral percutaneous femoral approach, with relining technique. Three years CT scan follow-up showed the endograft patency and size sac reduction.

Simplifying the use of a reline jig

The use of autopolymerizing acrylic resin to reline a complete denture is a time-effective procedure to accomplish refitting a denture to the supporting tissue. The use of autopolymerizing acrylic resin can be an effective adjunct to the standard heat-processed acrylic resin reline methods. It is cost-effective, quick, and easy to accomplish in most office settings. The most common disadvantage to this technique is the inability to control the acrylic mass during the polymerizing stage. Securing the denture to the jig with sticky wax (Sticky Wax; Kerr USA, Romulus, Mich) or other materials can also be messy and time-consuming. This article describes a reline technique using a vinyl polysiloxane material to retain the denture in the reline jig and to control excess autopolymerizing acrylic resin from bonding to surfaces not being corrected.

Reline materials--handle with care? An investigation into the effect of varying the powder/liquid ratio on some properties of auto-polymerising acrylic resin materials.

The fit of the denture base to the alveolar ridge progressively declines with alveolar ridge resorption. Once a denture becomes ill-fitting there are two main treatment options: to construct a new denture or to restore the fit of the existing denture. A denture may be relined as a laboratory procedure or at the chairside in the dental clinic. The chairside reline technique involves the direct application of auto-polymerising acrylic resin materials to the prepared denture base and the material is allowed to polymerise in the patient's mouth. The reline materials are generally supplied as a powder and a liquid. Clinicians and laboratory dental staff do not always follow manufacturers' recommended guidelines and the tendency can be simply to add varying quantities of powder and liquid until the desired consistency is achieved. This method however may have deleterious effects on the properties of the resultant material. The aim of the study was to investigate the effect of varying the powder/liquid ratio on some properties of three auto-polymerising acrylic resin reline materials. The properties investigated were the flow characteristics in terms of the manipulation and setting time and the hardness. Four powder and liquid ratios were chosen. For all the materials studied, a clinically useful lengthening of the manipulation time can be achieved by increasing the amount of liquid added to the powder. However, this is perhaps offset by the fact that it is associated with a corresponding increase in the setting time and resultant increase in clinical chairside time. There were significant differences in surface hardness when the powder/liquid ratio was altered.

Effects of reheating on the accuracy of addition silicone putty-wash impressions

The effect of the relatively high thermal contraction of addition silicones (polyvinylsiloxane) on the accuracy of stone casts was evaluated using the putty/wash relining impression technique and acrylic resin trays. Impressions were made at 37 degrees C and were divided into two groups. One group was poured at room temperature (22 degrees +/- 2 degrees C) and another group was reheated to 37 degrees C before pouring. Measurement of the dimensional changes failed to reveal improved accuracy of the stone casts poured at the same temperature as that reached during impression making. On the basis of this limited sample, it can be concluded that reheating the impression using the putty/wash relining technique did not improve the accuracy of the stone cast.

Tensile strength of elastomeric impression materials, adhesive and cohesive bonding

Numerous factors are known to effect the accuracy of elastomeric impression materials. Factors often overlooked are the quality of the bond between low-viscosity and high-viscosity elastomers and the presumed cohesive bond between materials during an impression reline procedure. This study examined the bond strength of condensation polymerization polysiloxanes, addition polymerization polysiloxanes, polyethers, and a light-cured polyether urethane dimethacrylate. Of the tested materials, light-cured polyether urethane dimethacrylate exhibited the greatest bond strength. The reline technique, light-body cured to previously cured heavy-body putty, yielded results similar to the simultaneous-cure technique. In terms of bond strength there is no advantage of one technique over the other. The corrective reline technique yielded acceptable results in bond strength. In general, the tested materials exhibited greater tensile strength than bond strength.

A prosthodontic approach to the surgical treatment of the epulis fissuratum

Simple excision of the epulis fissuratum results in loss of sulcus dept hand scar formation, hence the peripheral seal of full denture are obstructed. In order to avoid these condition, lyophilized porcine skin or dermis were used to excised surface for wound dressing, and treatment dentures were inserted one week after the operation which act as a splint maintaining sulcus depth. Furthermore, occlusal correction, which included to restore an optimal vertical dimension of occlusion of the old dentures, and correction of the extent of the tissue coverage by the old denture base were accomplished by modifying the old (treatment) dentures.Consequently, it seems that loss of sulcus depth and scar formation were reduced. The ridge relation was improved, and this improvement faciliated the eventual registration of the jaw relation.In broad lesion, it is difficult to correct the extent of tissue coverage by the resin bordermolding materials. Therefore, the extent of tissue coverage of old dentures without lesion by the impression technique before operation, and refitting the excised surface by instant chairside reline technique after the operation, it may be useful for the resolution of this difficulty.

Fabrication of custom trays from existing dentures

This technique rapidly and simply provides a custom tray which duplicates the tissue surface of the patient's previous denture. The custom tray is then used as if it were the denture in a reline technique to make a final impression.

Cost analysis of relined mercaptan rubber impressions

An investigation was conducted to compare the time and amount of material used in a corrective reline impression procedure and in a complete remake of a new double-mix impression. The reline technique required 22.22 gm less material, and the reline technique was achieved in approximately 7.6 minutes less time than that required for a complete remake. This results in a monetary saving while preserving quality.

The wing relining technique

The wing relining method has been described. It represents a simple laboratory relining technique with an effective control for alterations in the vertical dimension.

A Relining Technique in Activated Acrylic Resin for Complete Dentures

Good reproductions of the oral tissues and borders can be developed by the impression technique. A greater density of the activated acrylic resin is accomplished than is possible in the “direct” method. Dimensional stability is improved, and occlusal relations are maintained or can be developed. Color stability, density and accuracy of activated resins are greatly improved. Time-consuming laboratory flasking and heat-curing are eliminated. The procedure, from impressions to insertion, can be completed in 4 hours when necessary.

Relining complete dentures

A relining technique for complete dentures has been described. Wax impressions are made in the denture bases with the use of centric relation as a guide for positioning the dentures. The correct vertical dimension of occlusion is reestablished while a new interocclusal centric relation record is made. Centric occlusion is preserved by correctly positioning the lower denture to the upper denture after the casts have been mounted on the articulator. Hard Klinging Liner Plastic is used as the final relining material.
