ABSTRACT

In the last decade, spiral implants were introduced as a new tool for oral rehabilitation. A retrospective study has been planned to verify the effectiveness of this system in replacing cuspids. A series of 26 spiral implants inserted to replace cuspids were analyzed. Several variables related to a patient, anatomic site, implant, and surgery were investigated. Implant failure and peri-implant bone resorption were considered predictors of clinical outcome. Cox regression was then performed to detect statistically associated variables with the clinical outcome. From June 2010 to June 2014, 234 spiral implants were inserted in patients. Specifically, 26 fixtures were inserted to replace missing cuspids. Fifteen were inserted in females and 11 in males with a median age of 55 (max-min 29-77, STD = 14 years). One failed (i.e., survival rate SVR =96%). The mean follow-up was 16 months (max-min 1-41, STD = 10 months). Among the studied variables, none reached a significant statistical value. In the present report, the SVR and SCR were 96% and 88.46%, respectively. Statistical analysis demonstrated that no studied variable impacts the survival (i.e., lost implants) and clinical success (i.e., crestal bone resorption), so SPI is a reliable device to replace cuspid.
