Patients who needed SFE for implant placement were recruited into this clinical trial. A staged procedure (lateral window technique using CO3Ap granules, followed by implant placement after 7 ± 2 months) was employed in 13 patients. Bone-height increase and insertion torque values (ITVs) were assessed along with histological evaluation. The survival and success rates of 3-year functioning implants were also evaluated. Mean of bone-height increase after SFE using CO3Ap granules was 7.2 ± 2.5 mm and this increase allowed implant placement in all cases (17 implants). Mean of ITV was 25.1 ± 13.2 Ncm and primary stability was achieved successfully in all cases. Histological analyses revealed mature new bone formation (36.8 ± 17.3%) and residual CO3Ap granules (16.2 ± 10.1%) in the compartment after SFE. The survival and success rates after 3-year functional loading were 100% and no complications were found. These results clearly indicate the clinical usefulness of CO3Ap granules for SFE..

Methods: Maxillectomy patients whose swallowing function defined by Eating Assessment Tool (EAT-10) score and tongue functions (oral diadochokinesis: ODK, maximum tongue pressure: MTP) with or without obturator prostheses had been evaluated were enrolled in this study. The effects of the history of radiotherapy and soft palate defect on swallowing function were evaluated. The effect of radiotherapy on oral dryness was also evaluated. To examine correlations of swallowing function with continuous variables, Spearman correlation coefficients were calculated.

Results: A total of 47 maxillectomy patients (23 males and 24 females, median age: 71 [IQR: 63-76]) were registered. The median value of EAT-10 scores was 3 [IQR: 0-14]. Patients with the history of radiotherapy, but not with soft palate defect, showed significantly declined swallowing function. ODK and MTP of patients wearing obturator prostheses were significantly improved. No significant effect of radiotherapy on oral dryness was found. A significant correlation was found between EAT-10 score and MTP (P = 0.04).

Conclusions: Swallowing function in maxillectomy patients was relatively impaired and the patients with the history of radiotherapy showed lower swallowing function. Obturator prostheses could contribute to the improvement of MTP and ODK (/ta/). MTP may play a crucial role in swallowing in maxillectomy patients..

, J Prosthodont Res., 10.1016/j.jpor.2019.11.003., 2020.02, Purpose: The purpose of this study was to evaluate the effect of oral rehabilitation (maxillofacial prosthetic intervention and oral hygiene instruction) on oral health-related Quality of Life (OHRQoL) and oral hygiene condition in patients with maxillofacial defects and to explore the correlation between them in these patients.Methods: Twenty-five patients with maxillofacial defects who had been treated since April 2016 to March 2018 were included in this study. The scores of the Oral Health Impact Profile (OHIP) and O’Leary’s Plaque Control Record (PCR) were also identified as the scores of OHRQoL and oral hygiene condition, respectively. Statistical analyses were performed to compare between the scores of “pre” and “post” prosthetic treatment and to evaluate patient-related factors influencing these variables (age, the number of residual teeth and occlusal supports, and occlusal units (OUs)). The effect of combined chemo-radiotherapy (CRT) on each score was also assessed statistically. Furthermore, the correlation of OHIP and PCR scores was explored statistically.Results: Both oral rehabilitations could significantly improve OHIP and PCR scores. Significant correlations of the change of OHIP scores with age and OUs were detected. CRT had no significant effect on OHIP and PCR scores. No correlations between OHIP and PCR were observed. Conclusions: Although oral rehabilitation such as maxillofacial prosthetic treatment and oral hygiene instruction would be highly effective for improvement of OHRQoL and oral hygiene condition in patients with maxillofacial defects, there was no correlation between them..
12. Nishimura T, Ogino Y, Ayukawa Y, Koyano K., Influence of the wettability of different titanium surface topographies on initial cellular behavior., Dent Mater J., 2018.06, This study examined the influence of the time-dependent wettability of different surface topographies on initial cellular behavior. Titanium disks with smooth topography (SM) and three kinds of rough topography (sandblasted (SA), microtopography (M) and nanotopography (N)) were prepared. Time-dependent changes in surface wettability were observed in all surfaces as shown in previous studies. On SM surfaces, hydrophobic alteration influenced cell spreading and the activity of RhoA (a small GTPase protein of the Rho family), while no alterations were observed on rough surfaces except for the number of adherent cells. Serum adsorption could recover these functional deteriorations by hydrophobic alteration. These findings suggest that surface topography is a more potent regulator in initial cellular behaviors such as cell spreading and RhoA activation than surface wettability..

Though many reports have described severe infantile-malignant autosomal recessive OP, few have described the prosthetic management of adult OP. This report discusses the prosthetic treatment of adult OP. Although prosthodontists should try to reconstruct occlusal function as much as possible, a conservative prosthodontic approach may be a reasonable and recommended treatment option for minimizing the risk of further osteomyelitis and osteonecrosis..

7. YOICHIRO OGINO, Lyndon F. Cooper, kiyoshi koyano, Topography influences cellular functions and RhoA activity of titanium surface-adherent cells., 9th International Wrokshop on Biomaterials in Interface Science, 2014.08, Purpose: RhoA, one of Rho-family of GTPases, is known to influence cell adhesion and motility through organization of the actin cytoskeleton in response to various stimuli. The aim of this study was to investigate cellular functions and RhoA activities of the adherent cells on titanium substrates with three kinds of topography.
Materials and Methods: Three kinds of surface topography Ti disks were prepared. Smooth (S) surfaces were passivated with 30% HNO3. HCl-treated (H1) surfaces were grit-blasted with 100-μm aluminum oxide (Al2O3) particles, subsequently treated with 5N HCl and passivated with 30% HNO3. H2O2+H2SO4-treated (H2) surfaces grit-blasted with 100-μm Al2O3 particles and subsequently treated with 30% H2O2 and 2N H2SO4. These surfaces were characterized by SEM analysis and the measurement of surface roughness. To evaluate the effect of surface topography and RhoA inactivation on cellular functions, murine mesenchymal stem cells were cultured on each disk and cell morphology, RhoA activity, wound healing rates (cell migration) and osteogenic markers’ expressions were investigated with or without RhoA inhibitor (C3).
Results: Each disk showed a specific surface topography and surface roughness analysis indicated the highest roughness in H1 surfaces (H1>H2>S). Cell morphology was influenced by surface topography and C3. RhoA was activated in a surface roughness-dependent manner. The highest wound healing rate was observed on S surface. RhoA inhibition also enhanced cell migration on S and H1 surfaces, but not H2 surface. The expression of osteogenic markers was inhibited by C3 in S and H1 adherent cells, but not in H2 adherent cells.
Conclusions: Topography influences cellular functions and RhoA activity. However, the effect of RhoA inhibition on cellular functions may be in a surface topography- dependent manner.
