We had operated on implants for 7 years. The number of patients are 51.The total number is 144 implants. We use all implant of intraosseous type (ITI). Patient age is from 28 to 76. We operate on 92 implants into mandibular, 52 implants into maxillary.

 We have two types of pretreatment of implantation,

One is autogenous bone graft and another uses β-TCP, Trade name is OSferion. Autogenous bone graft is 17 cases, and using β-TCP is 8 cases.

 Post treatment, the case of falling out within 6 months, there are 2 implants at maxillary molar region and 1 implant at Anterior maxillary region. The case of extraction more than 1 year, there are 2 implants at Mandubular molar region.
