“…Regarding the Polyan IC samples, the results from Figure 3 shows that for the Control group the observed injection shrinkage is below 1% and a value of 0.2-0.8%, which is close to that defined by the ISO 294-4 Standard [4] and previous reports [11][12][13]. The storage in a dry environment of these materials has no influence on the polymer's volume.…”

Objective: To evaluate the change of diameter of different injection-molded thermoplastic materials. Material and Methods: Four thermoplastic injection-molded materials were analyzed (Bre.flex 2 nd edition, Vertex ThermoSens, Perflex Biosens and Polyan IC). A total of 432 test samples were made in the form of an "hourglass". All samples were divided into three groups: Group I (Control) -consisting of 36 test samples for each type of material, that was not exposed to artificial aging or a wet environment; Group II -consisting of 36 test samples for each type of material, that were artificially aged through dehydration; Group III -specimen were subjected to artificial aging without dehydration. The diameter of each specimen was measured with a digital caliper. Data were analysed using the Student's t-test. Results: Regarding to shrinkage, the samples from the Bf Control group have a mean value of 1.56 mm and was observed a shrinkage of the injection-molded polyamide material within 0.25%. The comparison between the samples from Group II and Group III showed statistically significant differences (p<0.001). There were no significant differences between groups for Thermosens and Biosens (p>0.05). The comparison between Group II and Group III for Polyan IC samples shows that Group III has a higher arithmetic mean value (p<0.01). Conclusion: Shrinkage of the polymers during the injection process is present in all materials. The thermocycling and the storage in a dry or in a wet environment of the samples results in a change of the diameter in almost every single type of material.

Objective:The aim of this study was to evaluate masticatory efficiency and patient satisfaction of ball and silicone-based soft liner and metal matrices for mandibular single implant-retained overdenture. Subjects and Methods: From the removable prosthodontics department clinic, Faculty of Dental Medicine, (Boys, Cairo, Egypt), Al-Azhar University, 10 completely edentulous patients were randomly chosen. The patients were divided into two groups, group I received a single implant-retained overdenture with the ball and metal socket, while group II received a single implant-retained overdenture with the ball and silicone-based soft-liner attachment. Statistical analysis was done using student t-test, the data distribution of normality was done by using the Kolmogorov Smirnov test. Results: It was found that group I recorded a significant increase in masticatory efficiency and there was no significant difference between the two groups in patient satisfaction. Conclusion: Silicone-based soft liners when used as a matrix instead of metal housing produce lower values of masticatory efficiency and equal values of patient satisfaction.

Aim: It was to compare Locator versus ball and socket attachment systems for single implant retained mandibular overdenture in relation to retention and oral health related quality of life. Subjects and Methods: Twenty completely edentulous patients were randomly selected from the Outpatient Clinic. Patients were divided into two groups, group (I) received single implant retained overdenture with ball and socket attachment while group (II) received single implant retained overdenture with locator attachment. Retention was measured three months interval after overdenture insertion for one year using force gauge device. Oral healthrelated quality of life was evaluated using OHIP-EDENT questionnaire after one year of overdenture insertion. Results: Group (II) recorded higher retention values than group (I) and the difference was statistically significant. Group I recorded higher Oral healthrelated quality of life mean values than group II and the difference was statistically non-significant. Conclusion: Locator attachment significantly increases retention of implant retained overdenture than ball and socket attachment. There is no significant difference in Patient oral health and quality of life between locator and ball attachments.
