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.
