Study population: patients receiving dental implants in both arches by guided surgery using double versus triple scan protocol .

Brief summary: 16 implant placement by surgical guide using double scan protocol versus triple scan protocol to Evaluate angular and linear deviation of virtual implants and actual implant position in completely edentulous patients according to scanning protocol C1(double scan technique) and C2 (triple scan technique) .

Detailed description: In this study we discuss linear and angular deviation of actual implant position using planning protocol C1(double scan technique) or C2 (triple scan technique) in completely edentulous patient .

Both protocols C1(double scan technique) and C2 (triple scan technique) indicated in completely edentulous patient and require C.T scan for patient wearing scan appliance .

In C1(double scan technique) , after CT scan for patient wearing scan appliance , two optical scan for the model with and without scan appliance.

In C2 (triple scan technique) , after CT scan for patient wearing scan appliance , CT scan for scan appliance alone .

Teeth positions in both protocols were identified by radio-opaque scan appliance .

16 implant placement by surgical guide using double scan protocol versus triple scan protocol ( two groups - 8 implants in each group ) to Evaluate angular and linear deviation of virtual implants and actual implant position in completely edentulous patients according to scanning protocol C1(double scan technique) and C2 (triple scan technique) .

Eligibility criteria: Inclusion Criteria:

1. patients totally edentulous arches.
2. patients with Bucco-lingual bone thickness \>6 mm allowing flapless implant placement
3. patients free from any systemic diseases that may affect bone quality e.g diabetes.

Exclusion Criteria:

1. patients with thin ridges.
2. patients with systemic disease that may affect bone quality.
3. Patients with poor oral hygiene and active periodontal diseases.
4. Anatomical situations requiring regenerative procedure.

Primary outcomes:
measure: Evaluation of angular deviation between planned implants in surgical guide and actual implant position in completely edentulous patients .
timeFrame: immediate post operative
Secondary outcomes:
measure: Evaluation of linear deviation between planned implants in surgical guide and actual implant position in completely edentulous patients
timeFrame: immediate post operative
