An Investigation of 131 Consecutively Placed Wide Screw-Vent Implants
Khayat, Philippe G. / Hallage, Pascale G. Habre / Toledo, Rafael A.
Between February 1995 and May 1996, 71 patients received treatment that involved 1 or more wide Screw-Vent implants. A total of 131 wide implants were placed. All patients were recalled 1 year after loading. Seven patients (14 implants) were lost to follow-up. Six implants were removed before completion of prosthetic treatment. One hundred eleven implants were evaluated at the recall examination. Almost all majority of patients (93 implants), it was a 17 months (range, 11 to 21 months). No implants were lost during the loading period. The overall survival rate was 95%. The survival rate for mandibular implants was 94%; for maxillary implants, it was 96%. These percentages were not statistically different. Crestal bone remodeling was examined using periapical radiographs. After 17 months in function, only 3 implants (2.5%) presented bone loss beyond the first thread.
