Primary outcomes

  1. implant stability analysis at the time of implant placement

    Time frame: baseline

    Implant stability will be measured by the resonance frequency analysis

  2. implant stability analysis 3 weeks after implant placement

    Time frame: baseline, 3 weeks

    Implant stability will be measured by the resonance frequency analysis

  3. implant stability analysis 6 weeks after implant placement

    Time frame: baseline, 6 weeks

    Implant stability will be measured by the resonance frequency analysis

  4. implant stability analysis 8 weeks after implant placement

    Time frame: baseline, 8 weeks

    Implant stability will be measured by the resonance frequency analysis

  5. change in pink and white esthetic score 2 months of loading

    Time frame: 2 months

    Pink esthetic scale and white esthetic scale will be used for evaluation of changes in white and pink esthetic parameters for implant-supported crowns

  6. change in pink and white esthetic score 6 months of loading

    Time frame: 6 months

    Pink esthetic scale and white esthetic scale will be used for evaluation of changes in white and pink esthetic parameters for implant-supported crowns

  7. change in pink and white esthetic score 12 months of loading

    Time frame: 12 months

    Pink esthetic scale and white esthetic scale will be used for evaluation of changes in white and pink esthetic parameters for implant-supported crowns

Secondary outcomes

  1. analysis of new bone formation 2 months after preservation of alveolar ridge

    Time frame: 2 months

    New bone formation will be assessed by histological analysis and histomorphometrical measurement

  2. analysis of new bone formation 4 months after preservation of alveolar ridge

    Time frame: 4 months

    New bone formation will be assessed by histological analysis and histomorphometrical measurement

  3. analysis of new bone formation 9 months after preservation of alveolar ridge

    Time frame: 9 months

    New bone formation will be assessed by histological analysis and histomorphometrical measurement
