SummaryObjectivesThe aim of this study was to test the effect of a single‐implant mandibular overdenture (SIMO), compared with conventional complete denture (CD), on masticatory performance measured by the mixing ability of a two‐coloured chewing gum.MethodsA sample of edentulous subjects was randomly assigned to the SIMO (n = 15) and CD (n = 19) groups. Patients in both groups received a set of new complete dentures, and the SIMO group received a single implant in the symphyseal region of the mandible (Straumann® Standard Plus SLActive®) and an eliptical matrix and ball attachment for denture retention. Masticatory tests were performed using a two‐colour chewing gum (Vivident Fruitswing, Perfetti van Melle, Turkey) for 20 and 50 chewing cycles. Colour‐mixing ability was assessed by electronic colourimetric analysis (ViewGum©, Dhal Software, Greece), expressed by the variance of hue. Tests were performed at baseline and at the 6‐ and 12‐month follow‐ups. Multilevel linear regression...

The purpose of this within-subject crossover clinical trial was to compare and evaluate the chewing efficiency, masticatory bite force, and patient satisfaction with conventional dentures and two implantretained mandible overdentures after 4 weeks of usage. Method: This within-subject crossover clinical trial was carried out in the Department of Prosthodontics in K.D Dental College and Hospital. A total 15 patients were selected for the study. To report the changes in chewing efficiency by chewing 6gms of peanuts with 40 chewing strokes and comparing the particle size of the chewed material between two implant retained mandibular overdenture with that of conventional denture using micro vu excel gantry type visual measurement machine. To report changes in masticatory bite force after transition of conventional complete denture patient to implant retained overdenture after using the prosthesis for four weeks each and recorded by digital transducer. To assess the patient satisfaction after transition of conventional complete denture patient to implant retained mandibular overdenture with help of OHIP edent patient satisfaction questionnaire. Results: The chewing efficiency for implant retained overdenture increased significantly than that of conventional denture. The particle size decreased to 76.34% for implant supported overdenture than that of conventional denture. The chewing strokes required by conventional denture was 69 strokes and that by implant supported overdenture which was 40 strokes to get the same mean particle size. The patients satisfaction after receiving the implant retained overdenture was significantly higher than that of complete denture. Conclusion: The provision of two mandibular implants significantly improves measures of oral function and better quality of life for edentulous patients.

Objective. The aim of this randomized clinical trial was to compare the masticatory ability subjectively between ball and Cendres+Métaux Locator (CM-LOC) attachment for a single implant retained mandibular overdenture throughout a 24-month follow-up period. Materials and Methods. Eighty completely edentulous patients were recruited. All patients received new complete dentures, and masticatory ability was recorded using a questionnaire (baseline record). All patients received a single implant in the midline of the completely edentulous mandible. After 3-month healing period, patients were randomized using sealed envelopes into two groups: ball or CM-LOC attachment. The same masticatory ability questionnaire was used to record masticatory ability for both groups after 2 weeks of pickup and 3-, 6-, 9-, 12-, and 24-month follow-up. Comparison between the study groups was done using Mann–Whitney U test for independent samples. Two-sided P values less than 0.05 were considered statistical...

E dentulism is considered a critical physical disability. 1 Tooth loss significantly reduces masticatory performance, 2,3 and masticatory disability in elderly individuals may lead to an unbalanced diet, reduced nutritional intake, and reduced health. 4 Although most edentulous patients wear conventional complete dentures, two-implant overdentures have been suggested as the first choice of treatment for mandibular edentulous patients in Europe and the United States. 5 The use of two-implant overdentures is reportedly associated with improvements in masticatory performance and satisfaction, reduced denture movement, and enhanced stability, as the two dental implants contribute to anchorage. It has been reported that the masticatory performance of complete denture wearers is approximately one-half to one-sixth of that of dentate patients. 6-8 Approximately 30% of complete denture wearers are reportedly dissatisfied with their dentures and experience various problems, 9 such as difficulty with chewing hard food, pain, instability in the denture,

A n implant-supported mandibular overdenture (ISO) with only two implants is a simple treatment in edentulous subjects. The number of implants to support the ISO may be restricted to two, as the number has been shown to be of minor importance for the treatment outcome. 1 Good long-term results with ISO treatment have been reported even in patients with severely resorbed mandibular ridges, 2-5 but the outcome has been described mainly in terms of implant survival rates and durability of implant superstructures. The relatively few reports on patient-based assessment of the outcome and on the functional effect of such therapy have shown better quality of life, greater patient satisfaction, better chewing and speaking performance, increased maximum myoelectric output, higher jaw-closing force, and less age-related bone loss after implant-supported prosthetic reconstructions 6-12 than with a conventional complete denture. This study assessed the outcome of treatment with ISO with two implants in a longitudinal, prospective controlled clinical trial on (1) patient satisfaction with the ability to chew and bite; and (2) chewing efficiency, bite force, and electromyographic (EMG) recordings. Materials and Methods Subjects The present study deals with functional data from 12 consecutive completely edentulous Caucasian patients (nine women and three men; Table 1) as part
Aim: The aim of this study was to evaluate chewing efficiency of the mandibular implant supported overdenture with OT Equator and mini ball and socket attachments. Subjects and Methods: From the removable prosthodontics department clinic, Faculty of Dental Medicine, (Boys, Cairo), Al-Azhar University, 10 completely edentulous patients were randomly chosen. The patients were divided into two groups, group I received mandibular overdenture supported by two implants with OT Equator attachment while group II received mandibular overdenture supported by two implants with mini ball and socket attachment. Chewing efficiency in terms of unmixed fraction (UF) was measured using chewing gum (after 5, 10, 20, 30 and 50 strokes). The measurements were performed at the time of insertion of overdenture (T1), after six months (T2) and after twelve months (T3). Results: It was found that OT Equator attachment recorded a significant higher chewing efficiency than mini ball and socket attachment in all observation times. Conclusion: OT Equator attachment is preferred regarding chewing efficiency in mandibular implant supported overdenture than mini ball attachment.

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.

Statement of Problem: Over 30% of the world population suffers from edentulism. Implant supported overdenture have been a relatively successful treatment option for edentulism and have shown to slowed the rate of residual resorption and maintain the vertical height of the residual. Purpose: The purpose of this study was to measure patient masticatary efficiency and satisfaction with the mandibular one-, two-, and three-implant-retained overdenture therapy when compared with conventional denture in a the same patients. Materials and Methods: Ten complete edentulous patients, who were wearing conventional complete dentures, were involved in this study. Three single piece endosseous implant of 3.0 mm in diameter and 13 mm in length were surgically placed in the mandible in the region of B, C, and D. Mandibular denture was connected for single, two, and three implant supported overdenture periodically and checked for masticatory efficiency using a bite gauge and patient satisfaction using a questionnaire. Results: Statistical analysis was done using Wilcoxon signed rank test. Four groups of bite forces when compared to each other. Group 1 was compared with Group 2, with the statistical value showing significance. Signed rank test showed no significance (0.268) when Group 2 was compared with Group 3. When Group 3 was compared with Group 4, and Group 1 compared with Group 4, rank test showed significant values. Four groups were compared with each other for patient satisfaction, Group 1 was compared with Group 2, with the statistical value showing no significance. Conclusions: A single midline implant supported overdenture can be considered as a suitable and cost-effective treatment option over conventional denture. The study concludes that masticatory efficiency of this single midline implant supported overdenture is better than the conventional complete denture.

One-year prospective clinical study comparing patient satisfaction and masticatory performance of mandibular overdentures supported by one versus two implants There is a lack of clinical evidence on mandibular overdentures (MOD) supported by a single implant. Objective: To compare patient satisfaction and masticatory performance in MOD supported by one versus two implants in a two-group parallel randomized clinical trial. Material and Methods: Twentyone patients wearing new maxillary and mandibular complete dentures (CDs) were randomly divided to receive one (GI, n=11) or two (GII, n=10) implants in the mandibular arch. Four months after implant placement, o-ring abutments were installed in the implants, and matrix attachments were placed in the lower complete dentures. Patient satisfaction with their dentures and masticatory performance were compared at baseline, 3, 6, and 12 months after the procedure. Data on patient satisfaction were analyzed using the Friedman test and the Mann-Whitney U test. Data on masticatory performance were analyzed using one-way repeated measures analysis of variance (ANOVA) and Student's t test (α=0.05). Results: Both groups exhibited a significant increase in overall patient satisfaction in all periods evaluated (p<0.05), except for GI after 12 months, which had values similar to baseline (p=0.74). Satisfaction levels of GI and GII were similar at baseline, 3 and 6 months, but GII showed higher satisfaction levels (p=0.01) than GI at 12 months. GI and GII exhibited a significant increase (p<0.05) in masticatory performance for all periods relative to baseline. However, GII had higher masticatory performance with dentures than GI, regardless of the period (p<0.05). Conclusion: MOD supported by two implants demonstrated better patient satisfaction in the follow-up at 12 months and better masticatory performance than MOD supported by one implant.
Clinical Efficacy of Single One Piece Implant Retained Mandibular Overdentures
The retention and stability of dental prostheses can be dramatically increased with the use of dental implants and subsequently oral functions of the edentulous patients can be greatly improved. This study was conducted to evaluate the clinical efficacy of single one-piece implant-retained mandibular overdentures compared with conventional complete dentures. Twelve edentulous subjects (mean age: 64) with moderate to severely resorbed mandibular ridges were treated with conventional complete dentures. The clinical efficacy in terms of retention, stability, tissue scores, satisfaction level and masticatory capacity was assessed after 6 weeks. After data collection, single one-piece ball type implant was placed at the mandibular midline area of each subject. After 6 weeks of implant placement conventional mandibular complete dentures were modified into implant-retained mandibular overdentures by O-ring attachment. Clinical efficacy was assessed at 1 week, 3 months and 6 months after lo...
