Abstract
Ideal implants should possess characteristics such as esthetics, morphology similar to natural teeth, durability, and high strength. Unfortunately, these criteria are sometimes unmet, leading to complications with the implants used. Therefore, this study aimed to compare periodontal indices between immediate loading (IL) and conventional loading (CL) implants. This study included 50 patients with dental implants: 25 with immediate implants and 25 with delayed implants. Inclusion criteria were age over 20 years and willingness to receive implant treatment. Exclusion criteria included smoking, pregnancy or lactation, history of periodontal treatment in the last 3 months, diabetes, cardiovascular disease, cancer, or immune system deficiencies. Research tools included a demographic form and clinical records collected via a checklist following the acquisition of the institutional ethics code. Data collection involved visiting dental clinics and completing the designed checklist for consenting patients. The mean probing depth (PD) after 6 months of loading was significantly increased in the immediate implant group compared to the delayed implant group (P < 0.01). Based on the results, the mean keratinized tissue width (KTW) after 6 months of loading was significantly increased in the delayed implant group compared to the immediate implant group (P < 0.05). The bleeding on probing (BOP) results showed that 44% of patients with delayed implants experienced bleeding, while 76% of patients with immediate implants exhibited bleeding. Furthermore, patients receiving delayed implants had a lower frequency of bleeding upon probing compared to those receiving immediate implants. Regarding implant location, 56% of immediate implants were placed in the maxilla and 44% in the mandible, whereas 52% of delayed implants were placed in the mandible compared to 48% in the maxilla. The gingival bleeding rate was higher in immediate implants than in delayed implants, while the gingival width was greater in delayed implants than in immediate implants. Additionally, most patients with immediate implants were located in the maxilla, and most patients with delayed implants were in the mandible.
