“…All 19 studies were non-randomized controlled trials ( Table 2). The follow-up period ranged from 1 to 11 years (mean 6.5 ± 3.6 years), including 1-year follow-up [10,15,16], 5-year follow-up [6,11,12,[17][18][19], 7-year follow-up [12,20], and more than 10-year follow-up [4,5,7,[21][22][23][24]. The sources of funding were only reported in four studies [7,13,20,21].…”

“…For IOD treatment, a bar attachment was used in 11 studies [4,5,6,12,13,17,19,21,23,25], and a ball attachment was used in three studies [17,21,23]. For the radiographic method to identify the average rate of PRRR, PAI was used in 10 studies [4][5][6][7]12,13,17,20,23,25], and vertical linear resorption was used in nine studies [10,11,15,16,18,19,21,22,24]. Among studies using the vertical linear resorption measurement, cephalometric radiographs were used in six studies [11,15,18,19,22,24], panoramic radiographs were used in two studies [10,21], and panoramic computed tomography was used in one study [16].…”

“…Among the 19 included studies, the mean rate of PRRR in patients using a CD was 0.5 ± 0.7 mm/year (range 0.01-2.4 mm/year) during a mean follow-up time of 5.8 ± 3.9 years (range 1-10 years) [5][6][7]10,11,15,16,18,22,24]. The average rate of PRRR in patients using a 2-IOD was 0.19 ± 0.15 mm/year (range 0.01-0.49 mm/year) during a follow-up time of 7.7 ± 3.3 years (range 1-11 years) [4][5][6][7]12,17,20,21,23,25].…”

Average rate of ridge resorption in denture treatment: A Systematic Review

Purpose: To clarify the rate of posterior residual ridge resorption (PRRR) in different denture treatments and the factors that can affect PRRR. Study selection: A bibliographical electronic search was conducted on MeSH, Web of Science, and Ovid databases. Hand searching was also conducted. Longitudinal studies recording the average rate of PRRR in the mandible were included. The effect size was calculated based on the mean rate of PRRR with standard deviation and group size. The random-effects analysis was used to perform meta-analyses across qualified studies. Results: A total of 2245 eligible studies were collected from the MeSH, Web of Science, and Ovid databases and hand searching. In the end, 19 studies met the inclusion criteria and were extracted. The average rate of PRRR in different mandibular denture treatments was assessed in this systematic review. The mean combined effect size was-1.05 ± 0.5 (95% confidence interval [CI]:-3.18-1.08) between four-implant overdentures and two-implant overdentures. The combined effect size was-0.01 ± 0.22 (95% CI:-0.93-0.82) between complete dentures and two-implant overdentures. Body mass index, number of dentures used, denture wearing habit, impression technique, artificial tooth material, and peri-implant bone resorption showed no significant effect on the rate of PRRR. Gender, denture material, and relining frequency showed a significant effect on the rate of PRRR. Conclusions: This review summarized different average rates of PRRR in mandibular denture treatments. Meta-analyses have reported that four-implant overdenture treatments can lower the rate of PRRR compared to two-implant overdenture treatments. However, there was no significant difference in the treatment effect between the complete denture and two-implant overdenture treatments.

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.
