Inclusion Criteria:
- Partial edentulism
- Missing more than three teeth in succession
- Presence of adjacent teeth
- Systemically healthy
- Good maxillomandibular relation
- Maximal mouth opening>5 mm
Exclusion Criteria:
- Poor oral hygiene
- Severe parafunctional habits, for example, bruxing and clenching
- Presence of clinically active periodontal disease as expressed by probing pocket depths≥4 mm in combination with bleeding on probing
- Maxillary sinus involvement
- Conditions that might lead to a possibly lowered regenerative capacity of the bone, for example, osteoporosis and Paget's disease
- Pregnant or expecting to be pregnant
- History of drug and alcohol abuse
- History of systemic diseases that would contraindicate oral surgical treatment, for example, uncontrolled diabetes (defined as HBA1c level >7%)
- Radiotherapy in the head and neck area
- On certain medications like bisphosphonates or steroids currently or within the past three months
- Unwillingness to return for the follow-up examination
- Smokers (more than20 cigarettes per day). Subjects smoking <20 cigarettes per day were requested to stop smoking before and after surgery

Aktiv komparator: GuideMia surgical template
A radiographic guide is prepared before CT/CBCT scan.
The CT/CBCT scan DICOM files are loaded in GuideMia program and converted into 3D computer images.
A surgical template is fabricated through this virtual planning.
