“…adopted a generalized estimating equation statistical method to increase the reliability of the analysis and concluded that implants placed in augmented areas were more prone to failure and therefore bone grafting was a risk factor of implant failure ( 37 ). In agreement with these findings, Yang and colleagues after assessing the survival rates and risk factors of implants placed in an institution in China between 2006 and 2017 in the early stage showed that bone augmentation was a significant risk factor of implant failure ( 38 ). Furthermore, it has been suggested that alveolar ridges with severe bone loss should be augmented first and allow a sufficient recovery and healing time prior to implant placement to ensure adequate bone formation ( 39 ).…”

Background To retrospectively assess the failure rate of implants placed in augmented and non-augmented sites and to investigate whether the time of implant and bone placement are associated with the risk of implant failure in a university setting. Material and Methods In this retrospective study, data were retrieved from the electronic patient database of the University of Minnesota School of Dentistry, USA to identify patients older than 18 years of age who received dental implant treatment. Patient characteristics and the adequacy of available bone were retrieved from the patients’ dental records and analyzed. Performing sinus lift and/or alveolar ridge augmentation in stages or simultaneously with implant placement and the need for multiple bone regeneration procedures were recorded. Kaplan-Meier plots and Cox regression models were created to analyze the data. Results Data from 553 implants were analyzed in the study. More than half of the implants were placed in the maxilla (56.8%) and posterior regions (74.3%). The overall survival rate was 96.9%. Sinus augmentation was performed in 19.5% of the cases, while in 12.1% of the included treatments an implant was placed simultaneously. Staged and simultaneous ridge augmentation occurred in 45.2% and 18.8% of the cases, respectively. Implants placed in an area following ( p =0.018) or simultaneously ( p =0.025) with sinus augmentation showed a significantly reduced survival. Cox regression analysis showed that smoking and simultaneous ridge augmentation and implant placement increased failure rates. Conclusions Within the limitations of this study, implants placed in tobacco users as well as in augmented maxillary sinuses, simultaneously or in stages, and in augmented ridges lead to higher implant failure rates. Key words: Bone grafting, dental implant, osseointegration, risk factor, survival rate, treatment outcome.

“…The loading factor is also very influential on the stability of the immediate dental implant. 16 Menchini et al, suggested that the placement of an immediate dental implant with a single restoration can be an option in missing one tooth. 17 It has been proven either on short or long research period (approach 100%) and bone damage marginal (0.42-2.69 mm).…”

Data on dental implant treatment's success and survival rate are still limited. Meanwhile, the data on the success and survival after implant placement and restoration can be used to evaluate materials, improve the dental implant treatment, and enhance the service quality at Hasanuddin University Dental Hospital. The purpose of this study is to analyze the dental implant survival rate, the contributing factors that enhance the survival rate, and the factors causing the failure of the dental implants at the Prosthodontic Clinic of Dental and Oral Hospital, Hasanuddin Uni-versity. The final study group consisted of 11 patients with 20 implants. Implant failure was categorized based on implant loss, mobility, or removal due to severe peri-implant infection or implant fracture. Implant survival rates were grouped based on sex, age, smoking habit, placement location, diameter, length, and placement time. The value of implant survival rate was assessed based on the presentation of successful implants. Of all 20 cases, five implants failed, indicating a cumulative implant survival rate of 75%. Based on the failure period, there are initial failure cases before loading and late failure cases after loading. One implant failed within the first six months, and two implants failed 2 years after insertion of the superstructure. The leading cause of implant failure before loading is osseointe-gration failure. In the case of implants that failed after installing the superstructure, peri-implantitis occurs continous-ly. It was concluded that the implant survival rate for patients at the Hasanuddin University Dental Hospital is 75%. Dental implant survival rates include gender, age, implant placement location, smoking habits, implant diameter, length, and immediate or delayed implant placement. The factors causing the failure of the implant in this study were osseointegration failure and peri-implantitis

“…Cosyn et al (2019) found that immediate implant placement resulted in a higher risk for early implant loss than delayed implant placement [41] . discovered that immediate placement of implants could increase the risk of early implant failure [42] . Immediate implant placement requires sealing soft and hard tissues and adequate primary stability and is more susceptible to bacteria.…”

Objective This study investigated the factors associated with early implant failure. Material and methods This retrospective study was conducted on 3,247 implants in 2,061 patients. Patient-related and surgery-related factors, including smoking, sex, diabetes, bone grafting, implant length, implant width, implant design, adjacent teeth, and insertion torque, were manually retrieved and analyzed. Using univariate and multivariate analyses, a generalized estimating equation (GEE) model was employed to evaluate factors related to early implant failure. Results The mean age of the patients was 49.2 ± 15.0 (18–91) years. Ninety-nine implants failed during the healing period. Three factors were statistically significant regarding early implant failure: smoking (odds ratio [OR] = 7.060, P = 0.008), implant design (OR = 6.983, P = 0.008), and implant length (OR = 7.500, P = 0.006). Factors including diabetes, bone grafting, location, adjacent teeth (root canal therapy in the adjacent teeth and the distance between the implant and adjacent teeth), healing method, and insertion torque did not exhibit a significantly higher early implant failure rate. Ninety-three sites with failed implants received replantation, and six implants failed during the healing period. Conclusions This retrospective study identified three factors associated with early implant failure: smoking, implant design, and implant length. A prospective study with larger sample size is needed in the future. Clinical relevance: There is fierce debate on the factors influencing early implant failure (failure during the healing period) in the rehabilitation and restoration of oral function in partially edentulous patients.
