“…No significant differences regarding cumulative 1‐year survival rate, both at the implant level and at the patient level between the Short‐ and the Standard‐MDI groups indicate good clinical behavior of short MDIs. Survival rates obtained in this study for the both groups are in accordance with other reports for standard length MDIs (Elsyad, ; Elsyad et al, ; Goiato et al, ; Griffitts et al, ; Hasan et al, ; Klein et al, ; Lemos et al, ; Marcello‐Machado, Faot, Schuster, Nascimento, & Del Bel Cury, ; Mundt, Schwahn, Biffar, & Heinemann, ; Mundt, Schwahn, Stark, et al, ; Park, Lee, & Shin, ; Peršić et al, ; Scepanovic et al, ; Šćepanović et al, ; Schiegnitz & Al‐Nawas, ; de Souza et al, ; Zygogiannis et al, ).…”

Objectives To assess peri‐implant bone level, survival and success rates of short (6 or 8 mm long) one‐piece mini‐implants (MDIs) in edentulous patients with extremely resorbed alveolar ridge (interforaminal height <10 mm) rehabilitated with mandibular implant overdentures and to compare them with patients having standard length MDIs in 1‐year prospective clinical study. Material and methods The Short MDI group consisted of 28 participants with interforaminal height ≤10 mm. Implants being, both, short and slim (short MDIs: 6 or 8 mm long, 2 or 2.5 mm wide) were inserted. The Standard‐MDI group included 35 participants (interforaminal height >13 mm) who received standard length MDIs (10–14 mm long, 2 or 2.5 mm wide). Primary outcomes were assessments of MDI peri‐implant bone level, survival and success rates; secondary outcomes were assessments of peri‐implant tissue, oral hygiene, and prosthodontic maintenance. Results The Short MDI group had mean marginal bone loss (MBL) of 0.26 ± 0.35 mm, 6.4% of failure, and 92.6% of, both, success and survival rates. The Standard‐MDI group had mean MBL of 0.34 ± 0.40 mm, 5% of failure, 95% of survival, and 94.3% success. There were no significant differences in MBL (p = .420), survival (p = .414), and success (p = .571) between the groups. The Short MDI group had significantly less plaque (p = .001) and bleeding on probing (p < .001). Conclusion Within the limitations of this study, short MDIs (6 or 8 mm long) in extremely atrophied mandibles (interforaminal height <10 mm) showed good clinical results in the first year of function.

“…The results of the study revealed non-significant difference between both groups regarding the first part of questionnaire (related to phonetics and esthetics) which support the null hypothesis that as long as there is no significant difference between the two treatment modalities so it is preferred to rely on the minimal simple treatment of edentulous mandible (two mini-implant) to decrease surgical intervention, time and cost of the treatment 9 .…”

“…Edentulous patients can be rehabilitated satisfactorily through implant-retained overdentures, eliminating problems common to conventional denture users, such as pain, decreased bite force (1), unsatisfactory retention, stability, aesthetic and phonetic (2), that too much compromise masticatory function (1). Thus, this type of prosthesis provides fewer injuries to the supporting tissues and more comfort to patients and increases their satisfaction with the rehabilitation treatment (3,4).…”

Effect of Cleanser Solutions on the Retention Force of O’ring Attachment: An in Vitro Study

et al. 2020

The aim of this study was to evaluate the effect of cleaning solutions on the retention force of o-ring-type overdenture attachments. The effect of four solutions on nitrile rings were evaluated: Cepacol (C), Cepacol with fluoride (CF), Listerine (L) and 0.05% sodium hypochlorite (SH); deionized water (DW) was used as a control. Matrices containing two implants and abutments and acrylic specimens with the metal capsules were obtained and divided into the groups. A simulation of 90 overnight immersions (8 h) was performed, and the tensile strength value was obtained at the beginning (T0) and in every 30 days (T1, T2 and T3) (n=6). In order to analyze o-ring surface damage after the immersions, a scanning electron microscopy (SEM) was used (n=1). For statistical analysis of the results, analysis of variance (ANOVA) and multiple comparisons with Bonferroni adjustment (test power=1.000; a=0.05) were used. There was a significant difference for the factors time (p<0.001), solution (p<0.001) and for the interaction time × solution (p<0.001). Considering the times of each solution, only for DW there was no significant loss of retention over time. Comparing the solutions in each moment, there was no difference among the solutions in T0. From T1, CF and SH provided less retention than DW (p<0.005). Through SEM it was possible to observe changes in the surface of the CF and SH nitrile o-rings. CF and SH should be avoided due to deleterious action in o-rings.
