Number of implants placed Number of implants lost Implant survival rate Method of implant osseointegration evaluation Results
Lorean et al. [1] 68 - IANL
11 - IANT
232 1 99.57% Not mentioned One implant loss was observed during follow-up period (average 20.62 months).
Morrison
et al. [2]
20 - IANT 30 0 100% Panoramic X-ray All 30 implants had successfully integrated. No evidence of infections, wound dehiscences, fractures or other serious complications.
Kan et al. [3] 10 - IANL
5 - IANT
64 4 93.8% Not mentioned Four of 64 implants had been removed. Two implants were lost due to infection after the patient had sustained a mandibular fracture. Two other implants were lost due to non-integration.
Peleg et al. [4] 10 - IANL 23 0 100% Panoramic X-ray All implants were clinically osseointegrated.
Khajehahmadi
et al. [5]
28 - IANT 65 0 100% Panoramic X-ray All implants survived and were subject to prosthodontic treatments. No evident of failure with at least 1 year of follow-up.
Dal Ponte
et al. [13]
1 - IANT 2 0 100% Panoramic X-ray On 2 and 7 years follow-up panoramic X-rays visible good osseointegration of implants without abnormality.
Vasconcelos
et al. [14]
1 - IANT 2 0 100% Panoramic X-ray Seven months after surgical procedure revealed excellent results.
Suzuki et al. [15] 1 - IANL 2 0 100% Panoramic X-ray In the postoperative period of 6 months, satisfactory results have been shown as regards to soft and hard tissues wound healing and temporary prosthetic rehabilitation.
Chrcanovic
et al. [16]
18 - IANT 25 3 88% Panoramic X-ray Three implants did not integrate.
Proussaefs [17] 1 - IANT 2 0 100% Perio-Test Unit The implants appeared clinically osseointegrated.

Three years post-loading revealed no clinical signs of pathosis (i.e., mobility, probing depth < 3 mm, pain, BOP)
Ferrigno et al. [18] 19 - IANT 46 2 95.7% Clinic and radiographic examination Two implants were lost (early failure). One implant was lost due to non-integration. Another implant was lost due to a mandibular fracture.
Kan et al. [19] 1 - IANT 3 2 33.33% Panoramic X-ray Three weeks after implants placement the patient experienced a spontaneous right mandibular fracture involving two anterior implants, which were finally removed.
Karlis et al. [20] 1 - IANT 2 2 0% Panoramic X-ray Panoramic X-ray revealed an area of radiolucency around the most posterior right implant with a non-displaced linear fracture through the inferior mandibular border. Finally, both implants were removed.
Proussaefs [21] 1 - IANT 5 0 100% Perio-Test Unit Implants appeared clinically osseointegrated 6 months after implant placement (tested with Perio-Test, Siemens, Bensheim, Germany). Implants were restored with cement-retained PFM restorations. Three years post loading X-ray examination revealed minimal marginal bone loss (< 1 mm).
Barbu et al. [24] 11 - IANL 32 0 100% Panoramic X-ray No implant loss was observed during the follow-up.
Del Castillo
Pardo et al. [26]
1 - IANL 3 0 100% Panoramic X-ray Six months after implants placement, no complications were observed.

IANL = inferior alveolar nerve lateralization; IANT = inferior alveolar nerve transposition.
