초록
Purpose: This study aimed to investigate the prevalence of complications in adjacent teeth and implants when the occlusal scheme changed from canine guidance to group function due to implant placement in canine sites and to compare them according to prosthesis type. Materials and Methods: This study included 41 patients, in whom 52 implants were placed at canine sites by the same clinician. The biological and prosthetic complications of canine implants, adjacent teeth, and implants were recorded. Fractures or mobility due to the traumatic force of occlusion in adjacent teeth were also recorded. The implants were divided into three groups according to the prosthesis type: (1) single crown (SC); (2) fixed partial denture splinted with anterior implants (SA); and (3) fixed partial denture splinted with posterior implants (SP). The prevalence of complications was compared between the three groups using the chi-square test. Results: Nine implants were restored with a single crown, 26 implants were splinted with anterior implants, and 17 were splinted with posterior implants. The prevalence of complications in canine implants was not significantly different between the three groups. Fracture of the adjacent teeth and biological complications of the adjacent implants occurred only in the SP group. Conclusion: The results of this study suggest that changes in the occlusion scheme due to canine implants can affect adjacent teeth and implants. Canine implants splinted with posterior implants could be more harmful than single and canine implants splinted with anterior implants.
