Abstract

Introduction: This prospective analytical study was conducted with the aim of determining the prevalence, severity and factors affecting the short-term complications of implant surgery.

Methods: In a descriptive cross sectional study, patients referring to the implant department of Tehran University of Medical Science from 2020 to 2021 were included (292 implants in 152 patients). Patients underwent Simple implant placement without hard and/or soft tissue grafts were included. After 7 and 14 days, ecchymosis, bleeding, swelling, delayed wound healing, infection, and trismus were recorded. Pain, the most common outcome after surgeries was assessed based on the number of days the patient had pain, the number of analgesics used and the severity of pain (Numeric pain intensity scale) using SPSS software version 16. The relationship between complications and measured variables was examined by logestic regression analyses.

Results: The most common complications on the 7th day follow up were ecchymosis (3.9%) and delayed wound healing (3.9%). The mean pain score was 1.61 ± 1.32. No patient had pain more than 3 days after surgery. The mean number of analgesic used was 2.23 ± 1.82. Based on logistic regression analyses, only patient age and the number of days of analgesics use showed a significant relationship with the number of analgesics used (P˂0.001). Neither the level of expertise of the surgeon nor the patients' gender had nosignificant effect on the degree of complications pain and amount of patient pain and the consumption of analgesics (P˃0.05). Patients with poor oral hygiene used more analgesics in comparison to patients with favorable oral hygiene.

Conclusion: The overall prevalence of post-operative complications after simple implant surgeries was less than 4%. The older the patient, the higher the consumption of analgesics.
