Dental Implant Success Rate

2019 - 2023

Dental implants are routinely placed in the maxilla and mandible to replace missing teeth or to provide greater retention for removable prostheses (such as dentures or partials). Many patients undergo rehabilitation after cancers or tumors of the oral cavity are resected and reconstruction is performed.

Dental implant specialists at the Head and Neck Institute had an overall success rate of 95% for implant integration in 2023 (N = 216). Of the 216 implants, 10 had signs of early failure of osseointegration and had to be removed. The international average for implant success is reported as 95%.¹

Implant success is commonly defined as implant immobility; no evidence of periapical radiolucency; mean vertical bone loss of < 0.02 mm after the first year of service; no persistent pain, discomfort, or infection; and implant does not preclude placement of a functionally and esthetically acceptable restoration.²
