SILVA, Alessandro Costa da; CAMPOS, Antônio Carlos de  and  MOREIRA, Roger William Fernandes. Analysis of intercurrences and complications in the placement of dental implants: a retrospective study. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2010, vol.10, n.4, pp. 63-78. ISSN 1808-5210.

Intrinsically, every surgical procedure presents a certain rate of associated intercurrences and/or complications. Hemorrhages, infections, paresthesias or dysesthesias and primary loss of implants are some of the most common intercurrences and complications related to surgical procedures in implant dentistry. This study conducted a retrospective evaluation of the rate of intercurrences and complications related to patients submitted to osseointegratable dental implant placement. A retrospective evaluation was made of 660 clinical record charts of patients submitted to osseointegratable dental implants in the period of 8 years, attended in the Oral and Maxillofacial Surgery Department of Piracicaba Dental School - Unicamp. The results showed that there was a higher rate of intercurrences and complications when patients were attended by residents (p= 0.015) and when the panoramic radiograph was the only preoperative image exam requested (p= 0.011). The results also showed a higher rate of intercurrences and complications in patients when they were submitted to surgical procedures of alveolar bone reconstruction (p< 0.0001). The presence of post-operative infection had a significant influence on the increase in the primary loss of implants (p< 0.0001).
