Clinical Trial Summary

3 groups of immediately Loaded implant-supported overdenture patients will be evaluated (overdentures supported by two standard-sized implant, overdentures supported by 4 mini implant d: 3.2 mm ,overdentures supported by 4 mini implant d: 2.75 mm) regarding stability, masticatory efficiency, patient's satisfaction, oral health related quality of life, Peri-implant crestal alveolar bone loss.

Description:

The implant-supported overdentures will be placed in immediate functional loading on the same day of implants placement. A direct restorative protocol will be applied to modify the existing prosthesis to implant-supported overdentures.

The evaluations of the primary outcomes will be conducted before implantation and after (1 - 3 - 6 - 12 - 18), except Peri-implant crestal alveolar bone loss will be conducted only after (0 - 3 - 6 - 12 - 18).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	change in denture stability	The evaluation will be by Digital force gauge, a Hook of orthodontic wire (18 gauge diameter) will attach to the labial flange of overdenture, the other end of wire will connect to the force gauge which will be pull vertically upward until denture retention lost, and then reading will record 3 times and means value will calculate.	T1: before implantation; T2: 1 month after loaded; T3: 3 month after loaded; T4: 6 month after loaded; T5:12 month after loaded
Primary	change in masticatory efficiency	The evaluation will be by test food filtering device,Where the subjects will chew a measured portion of test food (peanuts) for 20 strokes. The test food will strain through mesh sieve (2 mm opening). The volume of food remaining on the sieve and that passing through the sieve determined the masticatory performance.	T1: before implantation; T2: 1 month after loaded; T3: 3 month after loaded; T4: 6 month after loaded; T5:12 month after loaded
Primary	change in patient's satisfaction	The evaluation will be by 100 mm Visual Analog Scale (VAS), for which higher scores indicate greater satisfaction, They will be asked to rate their level of comfort, ability to chew, stability, ability to speak, ease of cleaning their prostheses and their general satisfaction.	T1: before implantation; T2: 1 month after loaded; T3: 3 month after loaded; T4: 6 month after loaded; T5:12 month after loaded
Primary	change in oral health related quality of life	The evaluation will be by oral health impact profile of edentulous (Ohip-Edent) instrument, Patients will answer questions of ohip-edent which included 7 domains: functional limitation, physical pain, psychological discomfort, physical disability, Psychological disability, Social disability, Handicap. Responses will made on a five-grade Likert-type scale: 0=never ; 1=hardly ever ; 2=occasionally ; 3= fairly often ; 4= very often. disability, social disability and handicap	T1: before implantation; T2: 1 month after loaded; T3: 3 month after loaded; T4: 6 month after loaded; T5:12 month after loaded
Primary	change in Peri-implant crestal alveolar bone loss	The evaluation will be by panoramic radiogram, Peri-implant vertical and horizontal alveolar bone loss will measure (in mm) at the mesial and distal surface of each implant.; implant	T1: on same day of loaded; T2: 3 month after loaded; T3: 6 month after loaded; T4:12 month after loaded
