Abstract

Aims: To aid the dentist, in a more precise method for the mental health assessment of edentulous patients, and isolates those who refuse complete denture wearing for psychological reasons. Materialsand methods: The study was conducted during the period from July 2004 to November 2005. One hundred members with especial criteria were agreed to participate in this study. They were collectedrandomly from Dental College of Mosul University and Dental Health Center at Mosul city. The members were asked to answer the Mental Health Questionnaires. Results: It was found that mentalhealth score decreased with females especially who refused the prosthodontic treatment, also groups with low educational and financial levels at same group. Members that received their prosthodontictreatment at the Dental Collage with age between (55–64) years old seamed to be achieved a highestlevel within the Mental Health Scale. Finally the members with high anxiety tendency, showed less mental health scores. Conclusions: The completely edentulous who refused the prosthodontic treatment, especially females, low educational and financial groups achieved the minimum scores with Mental Health Scale.

Abstract

Aim: To measure the depth of the palate for completely edentulous patients and relate this parameter to the type of reflection of the soft palate. Materials and methods: Fixed reference point was determinedin the hard palate of a hundred upper edentulous casts made by pouring impressions of completely edentulous patients attending the prosthodontic clinic in College of Dentistry, University of Mosul.This reference point was determined by drawing two lines, the first line from the center of incisive papilla to the fovea palatinae, and the second line crossing the first line exactly in its middle. Thecrossing point of these two lines was considered the point of measurement. A depth measuring digital vernia (Lezaco art, 2406 China) measuring to the nearest of 0.01 mm recorded the measurement. Thecurvature of soft palate was determined by measuring the angle formed by the highest point of the palate and a point one centimeter posterior to fovea palatinae. Results: The results showed that 65% of the measurements of the palatal depth fall in the moderate category of palatal depth and 79% of soft palate reflections were of gradual type. Conclusion: There is an acceptable success rate of completedenture could be achieved in cases of moderate palatal depth with gradual reflection of soft palate

Abstract

Dental laboratories are commonly confronted with individuals seeking alterations on their complete or partial dentures. Some of these problems may not be related procedure followed to produce such dentures in the dental laboratories, rather they may be the result of improper use or even unrevealed certain dental history by the patient due to lack of knowledge or just as a matter of careless.
Identifying the most common problems may help both technicians and patients avoiding repeating of casting procedure and costs as well as unnecessary efforts. The most common problem exhibited by wearers of complete and partial denture are loose dentures and lack of retention.Gum diseases are only found in patients wearing complete dentures (4.3%).

Abstract

AbstractAn impression taking for edentulous ridge is the first step in the fabrication of thecomplete denture prosthesis. Various theories have been proposed by differentauthors as how to achieve an optimum impression in different ways.The purpose of this study was to compare the retentive forces required to dislodgemaxillary complete denture bases fabricated by using different impression materials.Twenty completely edentulous patients were selected and three types ofimpression were made for each patient. The 1st group; final impression were madewith zinc oxide eugenol "ZOE", 2nd group; final impression were made with lightbody addition silicone impression material and 3rd group; final impression were madewith condensation impression material. Three stone casts were obtained for eachpatient and three denture bases were fabricated by short curing cycle, retention forceexamined and compared using strain gauge force transducer.Statistical analysis for the data collected using descriptive statistic, ANOVA andLSD, the result revealed that group A "Impression with ZOE" and B "Impression withaddition silicone" show nearly the same results while group C "impression withcondenation silicone" significantly less retentive force than that of group A and B.Retention of complete denture bases is greater in denture bases produced by zincoxide eugenole final impression material than the other examined final impressionmaterials.

Abstract

Background: Using of denture adhesives improved the retention and stability of complete denture, so it is important for the success of complete denture treatment when it is used according to its indications.Materials and methods: This project was carried out in an attempt to measure and compare the effectiveness of denture adhesives (Boots, Super corega, and Lacalut denture adhesive) in a well fitting maxillary complete denture at various time intervals. The retention of well fitting maxillary complete denture with saliva alone and with the use of denture adhesives at different time intervals was measured as a resistance to dislodgment using loading apparatus.Results: The study revealed that there is a highly significant improvement in the retention of a well fitting maxillary complete denture after using any one of the three types of the denture adhesive. Statistically the three type of denture adhesives used in this study have approximately the same effectiveness with slightly difference in the time of action.Conclusion: The use of any type of these denture adhesives that were accepted by patient (whether vegetable gum or synthetic polymer, powder or paste) can improve the retention of the complete denture.

Abstract

Background: The establishment of the correct vertical rest position is considered essential, because this position is a critical landmark in determining the vertical relation of occlusion. Unfortunately, the physiologic rest position is variable as it may be influenced by muscle tension, fatigue, and properioception. A study was therefore, undertaken to investigate the repeatability of vertical dimension measurement by different education degree groups. Materials and methods: thirty patients were investigated for vertical dimension measurement by different education degree groups (5th class undergraduate students, house officers dentists, MSc and PhD), depending on a very popular and simple method by using millimeter ruler. Result: the result showed that the difference in the vertical dimension measurements by the four different education degree groups was clinically not significant. Conclusion: 1.The vertical dimension measurements obtained from the undergraduates and house officer dentists were dependable. 2.The time-span of the measuring procedure has no effect on the determination of the vertical dimension throughout a single visit. 3.The caliper method was practical, simple and accurate in academic work. As The result of this study reveals the reproducibility of this method by all of the investigators.

Abstract

Background: The most common problem associated with the lack of retention of maxillary complete denture is faultyposterior palatal seal pps. The methods for achieving a pps include arbitrarily scraping the cast, selective pressuretechnique, and the physiologic impression technique.Material and Method: In this study forces required to dislodge a maxillary complete denture bases were comparedfor different types of posterior palatal seals (PPS) with different palatal forms by using a specially designed straingauge force tranducer and strain measuring device. Nine male and female subjects are selected with age range55-70 years. These patients with different palatal forms according to House's classification of palatal forms: Class I flat,Class II intermediate and Class III high. Using different impression technique the first ordinary impression with Zincoxideeugenol and scraping the cast for pps, the second physiological impression by using korecta wax No.4.Result: The results show very highly significant difference, between the different designs of pps and physiologicalimpression for each group.Conclusion: The physiological impression of pps give better retention because no over compression of tissues (withinthe physiological limit) and concluded that the form of palate has direct influence on the retention of completedentures and will aid in the selection of type of posterior palatal seal needed

Abstract

The denture retention and stability are dependent on saliva flow rate and quality,patients with dry mouth may have problems with the stability or comfort of maxillarycomplete dentures.Dry mouth is a common feature in the elderly, but is not clear what proportion ofincidences is related to functional disturbances and whether age persue and Genderplay a role. The aim of this study is to determine the effect of age on unstimulated(Resting) whole and stimulated saliva flow rates. It was determined in 100unmedicated, healthy individuals wearing complete dentures. The subjects weredivided into two age groups: group A(< 70 years), group B(> 70 years). A significantdecrease in the secretion rates of unstimulated whole saliva in relation to age wasobserved in the study population (p< 0.001).Females had significantly lower mean flow rates than males for unstimulated(resting) whole saliva.
