Oral health-related quality of life changes after placement of immediately loaded single implants in healed alveolar ridges or extraction sockets : a 5-year prospective follow-up study

Objectives: The impact of single implants on oral health-related quality of life (OHRQoL) is scarcely investigated, especially when combined with immediate placement and loading in extraction sockets. The aim was to describe prospectively the changes of OHRQoL with single implants placed in the esthetic zone in healed ridges or in extraction sockets after 5 years. Material and Methods: Ninety-six patients, enrolled at three clinical centers, received 102 single implants placed in a healed ridge (n = 54 implants/50 patients) or in extraction sockets (n = 48 implants/46 patients). Implants were immediately provisionalized, and permanent crowns were cemented after 12 weeks. Oral health impact profile questionnaires (OHIP-14) were completed before surgery, after 1 (provisional crown), 6 (permanent crown), 12 and 60 months, respectively. The overall OHIP-14 score pertains to seven domains with two items each and was assessed on a Likert scale of 0–4 (0 = never and 4 = very often). The evolution of the total OHIP-14 score and changes within all OHIP domains over time and between groups were assessed with a linear mixed-effect model analysis. Results: After 5 years, overall implant survival was 98%. The total OHIP-14 score for both groups combined decreased from 0.50 at baseline to 0.17 at 6 months (P < 0.001), indicative of improvement. For both groups, this remained stable up to 5 years (P = 0.41). However, after 5 years, the total OHIP-14 score revealed a statistically significantly higher improvement in the healed group compared with the extraction group (P = 0.027). Conclusion: Missing a single tooth in the maxillary esthetic zone leads to limited OHRQoL problems as reflected by a low overall OHIP score. However, OHRQoL improves less in the extraction group, reflecting that replacing a missing tooth is perceived as more beneficial than replacing a present tooth

Immediate functional loading of single implants: a multicenter study with 4 years of follow-up

Background: In the current scientific literature there are only few studies on the immediate functional loading of single implants. Aim: To present the 4-year survival rate, complication rate and peri-implant marginal bone loss (PIMBL) of immediately loaded single implants inserted in healed ridges and fresh post-extraction sites. Methods: Six centers were involved in this prospective study. The surgical and prosthetic protocol was defined in detail, before the start of recruiting patients. Recruitment of patients and performance of surgeries took place between February 2012 and February 2013. Criteria for inclusion were single-tooth gaps in healed ridges and fresh post-extraction sockets. All fixtures (Anyridge®, Megagen Corporation, Gyeongbuk, South Korea) were functionally loaded immediately after insertion and followed for a period of 4 years. Outcome measures were implant survival, complications, PIMBL. Results: Forthy-six patients (between 18 and 73 years of age) were selected. In total, 57 fixtures were placed (10 in fresh post-extraction sockets). After 4 years of functional loading, only one fixture was lost, therefore high survival rates (97.6% patient-based; 98.1% implant-based) were reported. In addition, a limited incidence of biologic (4.8% patient-based; 3.8% implant-based) and prosthetic (9.7% patient-based; 7.6% implant-based) complications was reported. The overall 4-year PIMBL amounted to 0.38 ± 0.21 mm (healed ridges 0.4 ± 0.21 mm; fresh post-extraction sockets 0.33 ± 0.20 mm). Conclusions: Loading single implants immediately seems to be a highly successful treatment procedure. However, long-term data are needed to confirm these positive outcomes

Clinical, aesthetic and patient-related outcome of immediately loaded single implants in the anterior maxilla: a prospective study in extraction sockets, healed ridges and grafted sites

Purpose: The objective of this prospective clinical study was to document the overall treatment outcome of immediately loaded single Astra Tech Osseospeed™ implants placed in extraction sockets, healed ridges and Material and methods: Forty eight patients in need of a single implant in the anterior maxilla (15-25) were recruited. Patients were allocated to a conventional implant treatment (CIT) or immediate implant treatment (IIT) group on the basis of specific criteria. If the buccal bone plate was damaged or missing upon tooth removal, patients were allocated to a grafted implant treatment (GIT) group. Irrespective of the treatment concept implants were immediately provisionalized. Hard and soft tissue alterations, aesthetic parameters (Pink and White esthetic scores, PES and WES) and patient’s opinion (OHIP-14 questionnaires) were registered at different time points. Results: After 1 year of function the overall implant survival rate was 98% with 1 failure following IIT. The mean bone level to the implant-abutment interface was 0.65 mm (SD 0.79), 0.85 mm (SD 0.64) and 0.56 mm (SD 0.44) for CIT, IIT and GIT. Complete papilla loss was rare following either strategy. Mean midfacial recession amounted to 1.00 mm (SD 1.15), 0.12 mm (SD 0.78) and 0.49 mm (SD 0.82) for CIT, IIT and GIT, respectively. The aesthetic outcome showed a mean PES of 10.30 (SD 1.89) and mean WES of 7.11 (SD 2.14), all patients considered. Patient’s satisfaction showed a significant improvement after 1 year of function on all 7 domains (p < 0.001). Conclusions: This prospective study showed that single implants clinically and aesthetically perform well under immediate non-occlusal loading conditions in the premaxilla. In this context it is of pivotal importance to stress that patients were carefully selected for IIT and GIT
