ABSTRACT

In the last decade, spiral implants were introduced in the market as a new tool for oral rehabilitation. A retrospective study has been planned to verify the effectiveness of this system to replace missing incisors. A series of 50 implants inserted to replace incisors were analyzed. Several variables related to the 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, 50 fixtures were inserted to replace missing incisors. Twenty-four were inserted in females and 26 in males with a median age of 55 (max-min 29-77, STD = 14 years). Two failed (i.e., survival rate SVR =96%), and 5 had a crestal bone resorption higher than 1.5 mm in the first year and an additional 0.2 mm in each following year of follow-up. (i.e., success rate SCR = 90%). Among the studied variables, none reached a significant statistical value. In the present report, the SVR and SCR were 96% and 90%, respectively. Statistical analysis demonstrated that no studied variable impacts the survival (i.e., lost implants) and clinical success (i.e., crestal bone resorption), so spiral implants effectively restore the aesthetic zone of upper and lower jaws.
