The Incidence of Mechanical Complication in Patients Treated with Single Tooth Implant: A Retrospective Cohort Study
Keywords:
Mechanical complication, Single tooth implantAbstract
Background: Nowadays, replacing lost teeth with dental implants has become more popular while the mechanical complications of the implant are still being reported. In Thailand, a few studies are relevant to the number of implants due to the increasing use rate. Objectives: The research aimed to study the incidence of mechanical complications and related factors of single tooth implant in patients from 2017 to 2018.Methods: From the study of dental records and intra-oral examination, 40 patients were treated with 70 single tooth implants by the Institute of Dentistry in 2017–2018. The test consisted of a clinical assessment and radiographs to assess mechanical complications and record them in dental records. Then the data was analyzed and displayed as a percentage and correlated the mechanical complications with other related factors. Results: The incidence of mechanical implant complications was 18.5%. The most common complication was loose contact, accounting for 12.8%, followed by screw loosening at 4.3%. Porcelain veneer fractures were found to be 1.4%. In this research, no other mechanical complications of the implant were found. A study of the relationship between the factors studied and the implant mechanics complications revealed that gender and improper occlusion of the crown were significantly associated with implant mechanical complications (p < .05). Conclusion: The incidence of mechanical complications and related factors of single tooth implant in patients of the Institute of Dentistry during the year 2017-2018 revealed the most common complication is proximal contact loss, screw loosening, and fractures of porcelain veneer respectively. Gender and improper occlusion of the crown were significantly associated with the occurrence of implant mechanical complications.References
