Implant failures associated with asymptomatic endodontically treated teeth

Incidence of Endodontic Implantitis and Implant Endodontitis Occurring with Single-tooth Implants: A Retrospective Study

“…Sussman presented two cases of type 1 and two cases of type 2 EIP, and three of the four cases involved mandibular anterior teeth. In 2001, Brisman et al (9 ) reported four type 2 cases in which implant infections occurred secondary to periradicular infection from adjacent teeth with previous endodontic treatment that appeared to be successful, one involving a mandibular anterior tooth and three involving mandibular posterior teeth. Two case reports involving six additional cases of EIP and two cases of implant failure after placement of implants into acutely infected sockets were also recently published (10,11).…”

The Resolution of a Periradicular Lesion Involving an Implant

“…Brisman et al (10) presented four cases of failing implants placed near a tooth with endodontic treatment. They concluded that "implant failures occurred adjacent to asymptomatic endodontically treated teeth with no clinical or radiologic evidence of pathology."…”

An Important Dilemma in Treatment Planning: Implant or Endodontic Therapy?

“…Some researchers suggest that implant failure may occur when the implant is positioned adjacent to teeth that are clinically symptomatic of periapical pathology or have radiographic periapical pathology (Shaffer et al, 1998;Tehemar, 1999;Brisman et al, 2001;Chou et al, 2010). According to these researchers, clinicians should be aware that if implant failure occurs in a tooth adjacent to one that has previously received endodontic therapy, further treatment or possible extraction of the previously treated tooth might be necessary before repeating the implant surgery.…”
