Incidental findings of implant complications on postimplantation CBCTs: A cross-sectional study.
BACKGROUND
Survival rates of dental implants are reported to be very high and seem to indicate minimal complications related to dental implants.


PURPOSE
The aim of this report was to evaluate in a cross-sectional study the prevalence of implant positioning complications as appears in postimplantation Cone-Beam Computerized Tomography (CBCT) in two of the major imaging facilities in Bucharest, Romania.


METHODS
Demographic and implant data was collected from two of the three main CBCT facilities in Bucharest, Romania. All postimplantation CBCT imaging were assessed and evaluated for the presence of different implant positioning related complications. Data were entered into Excel spreadsheet and analyzed statistically.


RESULTS
Of the 2323 CBCT's that were analyzed, a total of 160 (6.89%) presented with implant positioning related complications. Out of those, 62 cases revealed penetration of the implant to adjacent anatomic structure. More specifically, there were 21 instances of sinus penetration, 19 instances of nasal cavity penetration, 9 instances of inferior alveolar canal penetration, and 13 instances of lingual plate perforations. There were also 15 cases of adjacent tooth injury noted.


CONCLUSIONS
Despite the popularity of dental implants, the surgical placement of these implants is not a riskless procedure. Implant mal-positioning might be life-threatening and can lead to serious bleeding, airway obstruction, and unnecessary postoperative surgeries. Complications of dental implants are not obsolete and dental implant associated problems may not be apparent immediately. Surgeons must have proper training and use evidenced-based treatment planning in order to prevent dental implant complications.
