Retrospective clinical study on survival rate of osseointegrated dental implants in the early post

This retrospective clinical study was conducted to evaluate the clinical usefulness of a freely removable microlocking implant prosthesis (MLP) that was developed to overcome the problems with conventional implant prostheses. A total of 54 patients (male: 31, female: 23) and 100 implant prostheses were included. Patients were divided into three groups such as 6-12 months, 12-18 months, and 18-24 months according to the used period after implant prosthesis delivery, and the patients in each group were recalled for examinations of survival rate, marginal bone resorption, peri-implant soft tissue indices, and complications. The prosthetic complications were analysed by combining the recorded chart data during the periodic checks including the last call for this study. During a 2-year observation period, all the implants showed a 100% survival rate without clinical mobility and functional problems. There was no significant difference in marginal bone resorption, plaque index, and bleeding index over the observation period after implant prosthesis delivery. Probing depth of the 18-24 months group ( 1.5 ± 0.19 mm ) was significantly lower than that of the 6-12 months group ( p < 0.05 ). The main complication was abutment loosening (4%), followed by implant prosthesis fracture (2%) and food impaction (2%) which were recorded. Within the limits of the present study, the implant prostheses with MLP are considered to be an applicable and predictable treatment method.

Abstract Background: The purpose of this retrospective clinical study was to evaluate the clinical efficacy of mineralized collagen (MC) versus Bio-Oss for immediate implant implantation in esthetic area. Methods: Medical records of Department of Oral and Maxillofacial Surgery of Shandong Provincial Hospital were screened for patients who had been treated with immediate implant implantation in the esthetic area using either MC( Allgens®) or Bio-Oss®, between January 2018 and December 2019. All patients fulfilling the in-/exclusion criteria and following for a minimum period of 1 year after surgery were enrolled into the presented study. Implant survival rate, radiographic, esthetic and patient satisfactory evaluations were performed.Results: Altogether, 70 patients were included in the study; a total of 80 implants were inserted. All implants had good initial stability after implantation. The survival rate of implants was 100% at 1-year follow-up. The differences in horizontal and vertical bone loss between the Trail group (0.72±0.26mm, 1.62±0.84mm) and the Control group (0.70±0.52 mm, 1.57±0.88mm) were statistically no significant at 6 months after permanent restoration. Similar results occurred at 12 months after permanent restoration. Clinical acceptability defined by PES ≥ 6 (6.07±1.62 vs. 6.13±1.41) was not significantly different between groups. Patient satisfaction estimated by VAS was similar (8.56±1.12 vs. 8.27±1.44), and the difference was not statistically significant between the two groups.Conclusions: The biomimetic MC seems to be a suitable and feasible option for bone graft material in immediate implant implantation.
