Effects of abutment materials on the tissues surrounding dental implants immediately after loading: An in vivo study

Aim: The aim of this study was to evaluate the effect of PEEK abutments, an alternative to titanium abutments, with temporary acrylic restorations using immediate loading protocol on the marginal bone loss and peri-implant tissues. Methodology: This study was performed with temporary restorations using 32 titanium and PEEK abutments (14 titanium and 18 PEEK) on 32 implants performed on 21 patients (13 females, 8 males). Before surgical placement of the implants, intraoral and radiographic examinations were performed. The patients were divided into two groups as titanium abutment group (Grup Ti) and PEEK abutment group (Grup PEEK). In both groups, all implants were placed according to the manufacturer's recommendations. After surgery, impressions were taken using polyvinyl siloxane impression material and closed tray impression technique. The gingiva, which is thought to be formed on the model, was scraped and screwed onto the appropriate titanium or PEEK abutment analogue according to the groups and temporary restoration was prepared and applied on the implant. Results: The results of the statistical analysis show that abutment types have no significant effect on ISQ values (p>0.05), but the diameter of the implant significantly affected ISQ values independently from abutment type (p<0.05). Less marginal bone loss was observed in the PEEK abutment group compared to the titanium abutment group (p<005), and similar results were obtained in both groups in terms of periodontal scores (p>0.05). Conclusion: Within the limitations of this study, there was less bone loss in the PEEK abutment group (p<0.05). There was no difference between PEEK and titanium abutments in terms of ISQ values and clinical evaluations (p>0.05). How to cite this article: Gül İ, Zortuk M, Öztürk C.

The Difference

Abstract Introduction Marginal bone level is the criterion for implant success. Patient expectations for more natural looking implant restorations created the need to restore implants with more esthetically pleasing materials like Zirconia rather than conventional porcelain-fused to-metal (PFM) crowns. The aim of this study was to evaluate marginal bone loss around dental implants clinically and radiographically when restored with Zirconia and PFM prosthesis. Materials and Methods Two groups (control and test) were formed with 14 patients each. In the control group, the subjects were rehabilitated with PFM crowns and in the test group, the subjects were rehabilitated with Zirconia crowns. Rehabilitation was done after the healing period of 3 months. Radiographic evaluation was done at regular (baseline, 3rd, 6th, and 12th month) intervals. Results The results were statistically analyzed. Keeping in mind the limitations of the study, it was revealed that the difference in the crestal bone resorption in both the groups was not significant.

Distal Aspect

Evolution in the field of dental implantology made the replacement of missing tooth easy and quick. During initial phase of evolution, there was a need of 3 to 6 months of healing period to get teeth on implants but with advancement of technology and research, immediate replacement of missing teeth without waiting period could become a possibility. To access the efficacy of immediate loading in dental implantology using Hexacone® (IHDE DENTAL - Switzerland) dental implant. The objectives were to evaluate pain, infection, recession, loosening of abutment, fracture of implant/crown, de-cementation, peri-implant radiolucency, and marginal bone loss. Five patients (3 male and 2 female) who needed teeth replacement were included in the study. Among 5 patients, 3 patients needed single tooth replacement and the remaining 2 needed segmental replacement. Out of 7 implants 6 implants were placed in the healed bone and 1 was placed in the extraction socket. In case of healed bone, permanent prosthesis were given on 3 day. In case of extraction site, temporary acrylic crown was given on 2 day, which was replaced by permanent prosthesis after 3 month. These patients were evaluated at 7 day, 1 month, 3 months, 6 months and 12 months clinically and radiographically. Infection, prosthetic problems, peri-apical radiolucency, and implant mobility were not observed and marginal bone loss was observed during follow-up periods. On 6 months follow up, 0.5mm and 0.45mm marginal mean bone loss was observed on mesial and distal aspect respectively whereas the same was 1.24mm and 1.14 mm on 12 months follow-up respectively.The immediate loading for dental implants is a successful procedure that decreases the time for the patients to obtain a final restoration satisfying both esthetical and functional problems. Immediately loaded implants survive equally well in extraction socket. No significant difference was seen in survival when implants were placed in healed bone and extraction socket.

Abstract Purpose There is paucity in the studies that assess dental implants replacing failed dental implants due to peri-implantitis. This study aims to evaluate the clinical outcomes of these implants in terms of implant survival and marginal bone loss. Methods Patients in this retrospective study were selected if having one or more implants removed due to peri-implantitis and the placement and loading of dental implants in the same region from April 2010 to December 2019. Information was collected about the patient's demographic data, implant dimensions, surgical and prosthetic variables. Changes in peri-implant bone level, cumulative implant survival rate and technical complications were assessed. Results Three hundred and eighty one dental implants in 146 patients that were placed in the same position or one-tooth position mesially/distally to the site of explantation were included. The patients' mean age was 63 ± 10 years. Ninety seven patients were females and 49 were males. After a mean follow-up of 34 ± 17 months, two implants failed. The cumulative survival rate was 99%. The marginal bone loss was −0.1 ± 0.6. Immediate or delay replacement of the failed implant did not affect implant survival or marginal bone stability. All the prostheses were screw-retained and presented the following complications: ceramic chipping (3 events), resin tooth fracture (1 event) and prosthetic screw loosening (1 event). Conclusions Dental implants replacing failed implants due to peri-implantitis would be an option in the management of peri-implantitis. They showed high survival rate and marginal bone stability.

Abstract Objective The use of dental implants with different types of surface roughness and implant-abutment interface has brought about a situation of marginal bone loss. Therefore, the aim of this study was to analyze and compare marginal bone levels of different types of osseointegrated dental implants with platform switch (Group A: Ankylos, Mannheim, Germany) and platform match (Group B: Dentsply Xive, Mannheim, Germany, and Group C: MIS Implant Technologies, Karmiel, Israel). Materials and Methods One hundred and seven patients (52 men and 55 women) with a mean age of 54.79 (standard deviation ± 12.35) years and a total of 321 dental implants (Group A, n = 198; Group B, n = 58; and Group C, n = 65) placed in a private practice between April 2006 and May 2015 were retrospectively analyzed. In addition to demographic information and implant characteristics, marginal bone levels were evaluated by Image J (Wayne Rasband, National Institute of Health, Maryland) program. Results The mean age of all patients was 54.79 ± 12.35 years, and 51.5% of them were women. Implants supporting fixed bridge were most commonly used in all groups (65%), whereas only 20% were restored with a single crown and 15% with overdentures. In total, 47.5% of all implants showed no marginal bone loss. Mean bone loss in Group A was significantly lower (0.81 ± 1.60 mm) as compared to Group B (1.58 ± 1.59 mm) and Group C (1.18 ± 1.36) (p < 0.005). Conclusion Among different types of dental implants, platform switch seems to preserve marginal bone levels and increase the long-term success of dental implants.
