Volume 18, Issue 5 (12-2010)
Abstract
Introduction: The concept of treating edentulous patients by osseointegrated implants was first proposed in 1960s. To minimize the failure rate of implants, it has been recommended to keep the implants free of load during the healing period .Recent studies have been directed to achieve faster integration and shorter healing periods prior to implant restoration. Loading protocols (immediate loading , early loading) can best be interpreted on the biologic basis of implant integration. Each of these protocols needs special prerequisites and there are special risk factors for different loading protocols. Objectives: In this review article, different loading protocols and their surgical and prosthetic considerations are discussed.

Abstract

Introduction: Dental implants are the choice of treatment for missing teeth. Despite the very good results, implant treatment is also associated with some failures and complications. The aim of this study was evaluation of survival rate and tissue health indexes around the Dio® SM dental implants placed in patients of dental school and a private office in Isfahan from 2005 until 2010.

Methods: In this cross sectional study, 94 Dio® SM dental implants in 72 patients via convenience sampling were selected. After that  demographic information and Gingival index, Gingival Bleeding index around Dio SM implants, plaque index, pocket depth, Bone loss were fulfilled for patients. Data analyzed using t-test, Chi-square test, Wilcoxon and Pearson test with SPSS Ver. 20 statistical software, at α =0.05.

Results: Among  94 implants, 55.6 % in maxilla, 44.4% in the mandible, 53.19% single and 46.81% were multi-unit. Survival rate of total implants was 80.6% and 19.4% were failed because of different
causes. Among indices Gingival index(p=0/001), plaque index(p=0/020),pocket depth(p<0/001) were
significantly lower than theeth. Periodontal indices except bleeding index were significantly higher
in maxilla (p<0.05) but bone loss was not significant(p=0.071).

Conclusions: The results of this study showed that survival rate of Dio® SM implants is lower than acceptable rate but needs to more studies.

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.
