Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
- Adult
Accepts Healthy Volunteers
Yes
Description
Inclusion Criteria:
- All patients having completely edentulous maxilla and class I Kennedy mandible.
- Sufficient (not less than 15 mm) restorative space must be available (from the mucosa covering the crest of the residual ridge to proposed occlusal plane). This will be detected by a tentative jaw relation.
- All patients are of angel's class I maxillo-mandibular relationships
- Abutment teeth must meet certain requirements :
A. Abutment teeth should be healthy with good periodontal and bone support. B. should not show advanced destructions. C. should not show a pronounced degree of mobility or advanced gingival recession.
D. Crown Root Ratio for an abutment is 1:2
Exclusion Criteria:
- Sever undercuts or concavities on the buccal or lingual sides of the ridge.
- Systemic diseases that may affect bone changes such as diabetes and osteoporosis.
- History of radiotherapy in the head and neck region.
- Crown Root Ratio for an abutment is 1:1.
