Abstract

Aim and objective: This study aimed to evaluate the effect of removable partial dentures (RPDs) on masticatory performance (MP) and oral health-related quality of life (OHRQoL) in shortened dental arch (SDA) patients. Materials and methods: Twenty mandibular SDA patients with four occlusal units, opposing with maxillary complete dentition, that were natural teeth or fixed prosthesis, were recruited and measured MP by using gummy jelly (Glucolumn, GC Co. Ltd., Tokyo, Japan) and Glucosensor GS-II (GC Co. Ltd., Tokyo, Japan) (glucose extraction method). In addition, OHRQoL was assessed by using the oral health impact profile-14 questionnaire, which consists of 14 questions with seven domains. The total score and individual domain scores were calculated and used as parameters of OHRQoL. At 2 weeks after the final adjustment of RPD, MP and OHRQoL were assessed by the same method and questionnaire. These data were compared before and after rehabilitation. The p value of <0.05 was considered statistically significant. Results: A total of 20 SDA patients consisting of 17 (85%) females and 3 (15%) males who met the prescribed criteria (45–68 years, mean; 56 ± 8.23 years) were recruited. Both MP (p < 0.001) and OHRQoL (p < 0.001) were significantly improved after rehabilitation. Conclusion: These results suggested that rehabilitation with RPDs significantly improves objective MP and subjective OHRQoL in patients with SDA.

Abstract

Aim and objective: Compare the reliability and accuracy of shade selection done by the male observer and female observer with a digital shade matching device. Materials and methods: Tooth color was measured in 39 volunteer\'s maxillary right and left central incisor teeth with Vita classic shade guide by two different observers (male and female) against a digital shade matching device (Vita Easyshade compact). L, C, and H values and ΔE value determined by visual method using Vita classic shade guide against digital shade matching system (Vita Easyshade compact). ANOVA and Bonferroni multiple comparison statistical analyses were used to compare the data. Results: There was very little significant difference between shade selected by male and female observers against Vita Easyshade compact with respect to L, C, and H value (p < 0.001). ΔE shows a significant device difference where Vita Easyshade compact has the highest mean of 3.113 followed by Vita classic has least mean value of 2.475. Conclusion: Determining the shade of a tooth demands clinical skills and experience. The females achieved better results in terms of shade selection as they are more conscious about esthetics.

Abstract

Aim and objective: Interim restorations are a crucial part of fixed prosthodontic treatment. Frequently such prostheses are used to serve the purpose of the therapeutical strength of a specific treatment plan or the form and function of the designed definitive prosthesis. The present study has been projected to value the marginal fit of two dissimilar interim restorations fabricated by 3D printing and milling technique on two different finish lines (shoulder and chamfer). Materials and methods: Two typodont models of maxillary central incisors comprised prepared for the full coverage of dental restorations. Each typodont model was prepared using two different finish lines one with chamfer (C) and the other shoulder (S). Both the preparations were digitally scanned and exported as Standard Tessellation Language (STL) to software for the designing and fabrication of the full coverage dental restorations. Total 24 restorations were fabricated, 12 were 3D printed and 12 were computer-aided design/computer-aided manufacture (CAD/CAM) milled. In both types of restorations, half was fabricated on the chamfer finish line and the remaining half was fabricated on the shoulder finish line. Descriptive and independent t-test was done for intergroup comparison. Quantitative data were summarized using mean and standard deviation with a significance level of p < 0.001. Results: In this study, it was found that on shoulder finish line CAD/CAM-milled restoration showed the maximum mean marginal gap in the cervical margin as 77.42 μm, while 3D printed showed a gap of 41.08 μm. On the shoulder finish line 3D-printed restoration showed a maximum mean marginal gap in the cervical margin as 48.25 μm, while CAD/CAM milled showed a gap of 89.00 μm. There was a statistically highly significant difference present in the marginal gap between CAD/CAM and 3D printing at various locations in restoration with shoulder/chamfer finish line. There was no statistically significant difference in the marginal gap in both finish lines irrespective of the fabrication method. Conclusion: Both the shoulder and chamfer finish lines were equally effective. Restorations fabricated by 3D printing had less marginal gap than CAD/CAM milling but both values were within the clinically acceptable limit.

Keywords: Gingival zenith, Gingival zenith deviation, Gingival zenith line, Maxillary anterior teeth, Vertical bisected midline

PDF  |  DOI: 10.5005/jp-journals-10019-1317  |  Open Access |  How to cite  | 

Abstract

Aim and objective: To measure the deviation of the gingival zenith (GZ) of maxillary anterior teeth with the vertical bisected midline (VBM) and apicocoronal displacement of lateral incisor zenith from GZ level of central incisor and canine. Materials and methods: For 50 periodontally healthy subjects (age range 18–50 years) having all anterior teeth, alginate impressions were made and a diagnostic cast was obtained. Gingival zenith was marked and its deviation from the VBM was measured for the maxillary anterior teeth using the method described by Chu and Stappert. The apicocoronal distance of the GZ point of the lateral incisor was measured from the GZ level of the central incisor and canine. The data were tabulated and subjected to statistical analysis. Results: Gingival zenith deviation was greater in the central incisor, followed by lateral incisor and canine. The mean apicocoronal displacement of the GZ of the right lateral incisor was 0.606 ± 0.417 mm and the left lateral incisor was 0.537 ± 0.414 mm from the GZ level. Conclusion: Gingival zenith deviation can be mesial or distal and is tooth-dependent. It was found that in the majority of cases, lateral incisors showed coronal displacement of GZ from the GZ line.

Abstract

Aim and objective: This technique aims to demonstrate a practicable approach for the precise transfer of information from the provisional to the final full-mouth restorations. Background: The prosthetic rehabilitation of severely worn dentition often poses challenges to the dental practitioners as it necessitates several stages of treatment sequencing including multiple sets of provisional restorations, which require several adjustments over a reasonable period of time to establish the desired esthetics and functions. Provisional restorations help to visualize and communicate the treatment outcomes to the patient and the dental technician. The patient-specific information reflected in the provisional restorations should not be lost during the clinical procedures and must be accurately adapted to the definitive restorations. Technique: The method presented in this article is a variation of the “cross-mounting” procedure. The technique demonstrates the use of anterior composite index stabilized cross-mounting and putty matrix, which facilitates the design and fabrication of the metal framework and evaluates the available restorative space for the final prosthesis. Conclusion: This technique allows the restorative dentist to duplicate the prosthetic information gained from provisional restorations accurately in the final restorations, ensures better and accurate mounting, and allows verification of the centric relation before investing time in the fabrication of the definitive restorations.

Abstract

This case report aims to enhance the esthetics in the complete denture patients with the customized attachment cheek plumper by an innovative method. The loss of teeth in patients leading to a handicap can be severe due to the impairment of masticatory function and facial disfigurement leading to a negative psychological impact on the individual. To improvise on this, apart from the regular measures of teeth arrangements to obtain lip support, excellent denture esthetics can be obtained by providing additional support to the slumped tissues. A 62-year-old male patient with a sunken cheek appearance walks into the department a complete denture fabrication with cheek plumper is pronounced. This article narrates a basic, effortless, non-invasive, and innovative treatment substitute to enhance facial appearance in a completely edentulous patient with sunken cheeks by implementing detachable cheek plumper/cheek lifting prosthesis using customized attachments. The advantages of these attachments are that it allows ease of placement and cleaning; easily available and economic; due to their limited size can be easily jabbed in the denture flange. The present technique of cheek plumper/cheek lifting customized attachment can also be easily used in unconventional cases like restricted mouth opening, facial palsy, and so on.

Abstract

Rehabilitation of maxillary defects using obturator prosthesis helps in restoration of form, function, and esthetics. It obturates the oronasal communication improving phonetics and prevents nasal regurgitation of food and fluids. Successful obturator prosthesis relies on an accurate impression of defect site and a well-fitting definitive prosthesis with cast partial denture (CPD) framework. This requires precision and meticulous care at every step during the fabrication of the prosthesis. A functional impression allows physiological recording of defect site within anatomical limitations and fabrication of well-fitting hollow obturator. Esthetics may be restored by using cheek plumpers to provide fullness to the sunken cheek. This clinical report highlights a technique for fabrication of a definitive obturator using a functional impression technique utilizing tissue conditioner, light-curing resin for fabrication of CPD-based hollow obturator, and magnet-retained cheek plumpers to restore form, function, and esthetics in a patient with Aramany class II maxillary defect.

Abstract

The prevalence of head and neck cancers increases worldwide, the therapeutic arsenal of its management mainly includes surgery, radiotherapy (RTH), and the combination of these two therapies. Chemotherapy is also used as an adjuvant treatment. Brachytherapy (BT) is indicated for localized head and neck cancers of the tumors of the lips and the nasal pyramid, the oral cavity, and the oropharynx. Lead protection and positioning splints are generally used when BT is provided. They help protect uninvolved tissues as the dose that will be delivered is important. They are made before BT and positioned during irradiation. This case report presents a clinical case of a patient with lip cancer for treatment with BT and for which a lead protection splint for maxillary arch protection and mandibular positioning splint was given.
