Endosteal implant

the spiral designmodification was

Cotinued by creating burs to ease

and fit the insertion of the implant

.As the progression continued, the

subperiosteal (on the bone) implant

was developed inthe 1940’s in Swe-

den.And we became able to de-
termine the greatest strength and

thickness of bone to place screws

as fewer supports over the ridge

crest supposed and fewer struts

were needed .
The blade implant is now recognized as an endosseous implant. then Vent-

plant implant were developed and also crystallized bone screw . The basic
spiral design was turned into a flat plate with various configurations the two

variations made them possible to place it in either the maxilla or the mandi-
ble.

In 1975, an implant device placed through a submental inci-

sion was introduced it is the first transosteal implant called the

mandibular staple implant.Dr. P. Brånemark presented a two-

stage threaded titanium root-form implant; using pure titanium

screws it was the first time to be placed Four implants were in-

serted into the mandible for patient.The bone actually bonded to

the titanium surface. When the concept

of “osseointegration”.
