Outcomes
Primary Outcomes
survival rates of the implants
Time Frame: 5 years
The term surviving refers to those implants that are still in the jaw of the patient but either have not met success criteria or have not been tested for success.
success rates of the implants
Time Frame: 5 years
Success is graded in three qualities, depending on the extent and results of performed examinations. Grade 1. 1. Absence of mobility is checked by individual stability testing of the unattached implant. 2. Radiographic evaluation of each implant reveals not more than 1.0 mm of marginal bone loss during the first year of loading, followed by not more than 0.2 mm resorption per year. 3. Severe soft tissue infections, persistent pain, paresthesia, discomfort, etc. Grade 2. 1. Radiographic evaluation 2. Severe soft tissue infections, persistent pain, paresthesia, discomfort, etc, are absent. Grade 3. 1. Radiographic evaluation. Peri-implant pathosis, such as a peri-implant radiolucency is absent. 2. Severe soft tissue infections, persistent pain, paresthesia, discomfort, etc, are absent.
Secondary Outcomes
- Marginal Bone Loss(5 years)
- Pink Esthetic Score(5 years)
- Patient satisfaction - Questions will be scored on 100mm visual analog scales. The patients marked their response on a horizontal line for which the most negative expression corresponded to 0 and the most positive to 100.(5 years)
- Patient satisfaction with single-tooth implant treatment measured with the Oral health impact profile-14 questionnaire(5 years)
