“…(+)-Tartaric acid (5-10 wt.%) ( Figure 5A) improves the rheological properties of GPCs by extending the working time and sharpening the onset of the setting time [40]. Results of Wilson et al were confirmed by Prosser et al [87], who showed by means of 13 C Fourier transform NMR spectroscopy that tartaric acid reacts preferentially with the glass and prevents the early binding of cations to the polyanion chains, resulting in increased working time. Tartaric acid is fully complexed at pH≈3, and complexing by PAA then occurs with the pH of the set cement rising to pH≈5 [87].…”

“…These features have made them attractive candidates for expanded applications in hard tissue repair. However, whilst their use in orthopedic applications has long been mooted, their non-dental clinical use has been limited to ear, nose and throat applications [10][11][12][13]. This is due to certain outages in their properties, including the following [2,14]: (a) Clinical literature supporting defective osteoneogenesis and fatal encephalopathy arising from aluminum ions (Al The majority of research into CGPCs has focused on changing the glass composition because it is capable of controlling both setting chemistry, strength [15,16] and ion release.…”

Abstract Glass polyalkenoate cements (GPCs) have been used in dentistry for over 40 years. These novel bioactive materials are the result of a reaction between a finely ground glass (base) and a polymer (acid), usually poly(acrylic acid) (PAA), in the presence of water. This article reviews the types of PAA used as reagents (including how they vary by molar mass, molecular weight, concentration, polydispersity and content) and the way that they control the properties of the conventional GPCs (CGPCs) formulated from them. The article also considers the effect of PAA on the clinical performance of CGPCs, including biocompatibility, rheological and mechanical properties, adhesion, ion release, acid erosion and clinical durability. The review has critically evaluated the literature and clarified the role that the polyacid component of CGPCs plays in setting and maturation. This review will lead to an improved understanding of the chemistry and properties of the PAA phase which will lead to further innovation in the glass-based cements field.

The ossicles may be affected through the mass effect of the pathological tissue in chronic otitis media. Ossicular reconstruction may be accomplished using the patients' own ossicles or with alloplastic materials. Glass ionomer ossiculoplasty is a fast, efficient, safe and cost-effective method and it has been used more frequently in recent years. Forty-six patients who had surgery for chronic otitis media were included in this study. All patients had an incus long process defect and a normal stapes superstructure. Ossicular reconstruction was performed using glass ionomer cement (GIC) (Ketac-Cem, Espe Dental AG, Seefeld, Germany) in 23 patients (group 1), while incus interposition was performed in other 23 patients (group 2). Preoperative and postoperative air pure tone averages of the group 1 patients were 42.8 and 35.2 dB, respectively (p < 0.01). These values were 42.9 and 34.5 dB in group 2 (p < 0.01). Two groups were similar with respect to postoperative hearing gain (p > 0.05). The air bone gap of group 1 was 27 dB preoperatively and 20.7 dB postoperatively. These values were 28.7 and 20.2 dB, respectively, in group 2. The closure of air bone gap was statistically significant in both the groups (p < 0.01, p < 0.01). The comparison of the mean gains of the air bone gap revealed no difference between the groups (p > 0.05). In conclusion, the use of both GIC ossiculoplasty and incus interposition are efficient methods for reconstruction of incus long process and one is not superior to the other. A larger study population may be useful for comparison of these methods.

“…These techniques can now be replaced by ossicular bridging with hydroxyapatite bone cement. Biocements have proved their value in otologic surgery as they have ideal adhesive and osseointegrative characteristics [10] . A major advantage is the fact that the ossicular chain can be restored in a more physiologic way and with only minimal manipulation.…”

“…While biocompatible prostheses were initially developed to improve hearing in chronic middle ear disease and otosclerosis, they also proved their usefulness in traumatic disease treatment [2][3][4][5][6][7][8][9] . A recent innovation is the application of hydroxyapatite bone cement, which appears to be a reliable technique to restore the energy transfer in a more physiological way [10,11] . Ossicular dislocations are far more common than fractures.…”

OBJECTIVE:The purpose of this study was to investigate etiological, clinical, and pathological characteristics of traumatic injuries of the middle ear ossicular chain and to evaluate hearing outcome after surgery. MATERIAL AND METHODS:Thirty consecutive patients (31 ears) with traumatic ossicular injuries operated on between 2004 and 2015 in two tertiary referral otologic centers were retrospectively analyzed. Traumatic events, clinical features, ossicular lesions, treatment procedures, and audiometric results were evaluated. Air conduction (AC), bone conduction (BC), and air-bone gap (ABG) were analyzed preoperatively and postoperatively. Amsterdam Hearing Evaluation Plots (AHEPs) were used to visualize the individual hearing results. RESULTS:The mean age at the moment of trauma was 27.9±17.1 years (range, 2-75 years) and the mean age at surgery was 33.2±16.3 years (range, 5-75 years). In 10 cases (32.3%), the injury occurred by a fall on the head and in 9 (29.0%) by a traffic accident. Isolated luxation of the incus was observed in 8 cases (25.8%). Dislocation of the stapes footplate was seen in 4 cases (12.9%). The postoperative ABG closure to within 10 and 20 dB was 30% and 76.7%, respectively. CONCLUSION:Ossicular chain injury by direct or indirect trauma can provoke hearing loss, tinnitus, and vertigo. As injuries are heterogeneous, they require a tailored surgical approach. In this study, the overall hearing outcome after surgical repair was favorable.
