Inclusion Criteria

  • •Generally healthy adult patients (ASA â… , â…¡) ranging 20-65 years old;
  • •Good oral hygiene and periodontal conditions (full-mouth plaque and bleeding score ≤ 25%);
  • •Single-tooth vertical or combined alveolar defect in posterior mandible;
  • •Alveolar bone defects ranging 2-6 mm below buccal cemento-enamel junction (CEJ) connection line of two adjacent teeth.
  • •Narrow flat edentulous ridge leads to larger crown-implant ratio, unsatisfactory esthetics, unpredictable implant integration and long-term prognosis than normal ridge;
  • •Available bone height smaller than implant length selected;

Exclusion Criteria

  • •Severe systemic disorders that contraindicate oral surgeries;
  • •History of head and neck malignancy and related chemoradiotherapy;
  • •Long-term use of steroid or immunological therapy (≥ 6 months);
  • •Severe osteoporosis (≥ 2 fragility fractures);
  • •Oral / intravenous bisphosphonate therapy ≥ 5 years;
  • •Pregnancy and lactation for female patients;
  • •Interocclusal restoration height available < 4.0 mm at edentulous area;
  • •Severe tempromandibular joint (TMJ) disorders and parafunctions;
  • •Bone augmentation procedure at the same site within the past one year;
  • •Additional soft tissue augmentation procedures at the same site within the past six months;
