Abstract
The study was design to investigate the clinical effect of Micro implant system in Italy on immediate mandibular implant-supported overdenture. A total of 192 patients with mandibular edentulous treated in our hospital were randomly divided into 2 groups in which the control group consisted of 96 patients treated with immediate mandibular implant-supported overdenture by Xive implant system, while the observation group included 96 cases treated with the overdenture by Italy Micro implant system. Patients were followed up for 1 year and then the states of implant-borne overdentures, marginal bone resorption around alveolar bone, the compatibility of implant restorations with adjacent teeth, adverse events and satisfaction degree were compared between the groups. According to the results of 1-year follow-up, the resorption around alveolar bone of the observation group was significantly higher than that of the control group (p<0.05). In the observation group the differences in labial gingival margin position, gingival color and texture were significantly better (p<0.05) as compared to control group. The incidence of adverse events was notably lower (p<0.05). The Italy Micro implant system has significant curative effect on mandibular implant-supported overdentures with good compatibility of the implant restorations with adjacent teeth and low incidence rate of adverse reactions, so it is worthy of clinical application and spreading.
Highlights
Implant overdenture, usually relying on attachments, provides good support, retention and stability (ELSYAD; ABID; ELKHALEK, 2017) The denture is connected with fixture abutments through different attachments to form readilyremoved implant supported overdentures in patients
This study aims to investigate application effect of the Italy B&B planting system so as to provide reference for mandibular overdentures, with the results reported as follows
The results of this study showed that compared with the immediate mandibular implant supported overdenture by Xive implant system, the overdenture by Micro implant system has significantly higher success rates of implantation and restoration
Summary
Usually relying on attachments, provides good support, retention and stability (ELSYAD; ABID; ELKHALEK, 2017) The denture is connected with fixture abutments through different attachments to form readilyremoved implant supported overdentures in patients. Several studies mentioned that by increasing the number of implants, the retention and stability improve, and correspondingly the loading placed on individual implants decrease (KRONSTRÖM; WIDBOM; SODERFELDT, 2006). Mandibular over-denture retained by 2 implants has become the first choice of treatment for edentulous individuals due to the decreased treatment cost, and invasiveness of the operation (FITZPATRICK, 2006; ODA et al, 2017). Based on the fact that mandibular canines and premolars are usually the last to be lost, and the most resilient teeth, recommendations have been reported for these teeth on abutment selection, load
