入选标准
- •Patients are free from any systemic conditions and bone metabolic diseases that might interfere with the surgical intervention, soft tissue or hard tissue healing.
- •Edentulous anterior or posterior maxilla with deficient alveolar ridge that is less than 5 mm measured from the crest of the alveolar ridge to the nasal or maxillary sinus and less than 4mm in buccolingual width.
- •The minimum number of missing teeth in the alveolar ridge is two adjacent teeth.
排除标准
- •Intra-bony lesions (e.g. cysts) or infections (e.g. abscess) that may retard the osteotomy healing.
- •Previous grafting procedures in the edentulous area.
