The objective of this invitro study was to evaluate gradual loss of retention at different time intervals between four different colour coded retentive caps of locator R-TX attachment system through 3000 cycles resembling 3years of attachment usage. Material and Methods. According to prosthetically driven implant placement, two implants were digitally planned and placed by 3D printed surgical stent in an epoxy model. Forty-eight mandibular complete dentures divided into four groups (12 dentures for each group) were constructed to compare Loss of retention between (12 pairs of locator R-TX each retention cap: zero retention, low retention, medium retention and regular retention), each was subjected to insertion and removal cycles resembling 3years of patient usage. Retention values at zero, one, two, three years were recorded using universal testing machine. Results: Locator R-TX medium &low retention showed no statistically significant retention values through three years while locator R-TX regular retention cap showed better retention values at zero, first, second year of use. Conclusion. Locator R-TX attachment systems low, medium, regular retention cap had no statistically significant different retention values at the end of third year of use while there were only statistically significant primary retention values.

Single Bond™ universal adhesive was used to bond each dentin substrate either after no etching or etching of dentin, after which, resin composite was used for build-up. These specimens were then tested for shear bond strength (SBS). The results were then analyzed by two-ways ANOVA. Results: Single Bond™ universal bonded to sound dentin had statistically significantly higher SBS mean values compared to CAD. Single Bond™ applied after separate etching step of dentin showed a statistically higher SBS compared to self-etching method when bonded to sound dentin.

Methods: Thirteen patients with age range 21-40 years old having atrophic anterior maxillary ridge ≤3mm horizontally were included in the study. All patients were subjected to ridge augmentation using composite bone graft and retromolar cortical shell that was fixed in place by two micro-screws. The alveolar ridges were assessed and compared by cone beam computed tomography (CBCT) in the pre-operative, immediate and 4 months post-operative phases by taking linear measurements at the same points after making fusion. The measurements were taken at the crest of the ridge, midway and more apically. The CBCT images were evaluated for the actual gain in width of the alveolar ridge. Statistical analysis was performed to compare CBCT and clinical findings. Results: At the crest of the ridge, midway and more apically the results showed a statistically significant difference between pre-operative and immediate post-operative results (P0.05). The mean increases in crestal bone width, midway and apically at 4 months postoperatively were 3.66mm, 4.01mm and 3.5mm respectively. Conclusion: 3D reconstruction of anterior maxillae with autogenous retromolar cortical shell is a reliable technique with stable outcomes. Two micro- screws Stabilization provides stability and minimal graft resorption. Moreover, the technique allows for implant placement 4 months post-operatively without further re-grafting.","PeriodicalId":100562,"journal":{"name":"Future Dental Journal","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79664150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many treatment modalities with different success rates have been proposed aiming to solve this complication or prolong the survival of the dental implant, of which are guided bone regeneration and soft tissue regeneration around the affected implants. Patients and Methods: This prospective study was carried in the hospital of Future University. 11 Patients (1 Male – 10 Females) with 20 Maxillary implant sites demonstrating soft tissue dehiscence were randomly allocated to either a guided bone regeneration (GBR) group (Control) in which patients received a mixture of autogenous and xenogeneic bone graft substitute covered by a native collagen membrane fixated with titanium tacks over the affected implants or a connective tissue graft and coronal flap advancement (CTG + CAF) group (Intervention) in which patients received a de-epithelialized connective tissue graft harvest from the anterio-lateral hard palate combined with a coronally advanced flap. Recession levels were measured at baseline and at 1,3 and 6 months post operatively, while probing depths and bleeding indices were measured at baseline and 6 months post operatively and patient satisfaction levels were recorded through a visual analogue scale (VAS) questionnaire 6 months post operatively after completion of the follow up period. Results: Out of the 11 patients (1 Male – 10 Females) enrolled in this study, no major post-operative complications were encountered, the most common complication was post-operative swelling and edema that usually peaked 48 hours after surgery, which was more evident in the GBR group. Soft tissue recession levels measured from implant platform to gingival margin was significantly higher at baseline in GBR group compared to CTG+CAF group (P=0.042).

Material and Methods: This is an in-vitro study in which translucency of six pre-sintered and pre-shaded zirconia materials (In Coris ZI, In Coris TZI, Bruxzir Solid, KATANA HT, KATANA ST, and KATANA UT) was compared to a low-translucency, lithium disilicate glass-ceramic material (IPS e.max CAD LT, Ivoclar Vivadent). The ceramic blocks were cut in the form of plates of dimensions (14x10 mm) and of different thicknesses (0.5, 0.7,1 mm). Thirty specimens of each ceramic material were classified into three groups according to thickness (n=10) such that the total number of specimens is 210. After all zirconia specimens were sintered and lithium disilicate samples were crystallized, TP was determined using dental spectrophotometer VITA Easyshade Compact. Same procedure of translucency measurement was done again after samples were subjected to accelerated autoclave aging. Results: Paired-Samples T- Test showed that aging caused significant reduction in TP in all materials in all thicknesses. Moreover, there was statistical significant difference (P < 0.05) between different ceramic materials where e.max CAD LT showed the highest (TP) and In Coris ZI showed the lowest TP in all thickness groups.

PI3k/Akt signaling pathway plays a significant role in regulating diverse cellular functions. This includes cell growth, proliferation and survival via inhibition of apoptosis, transcription and protein synthesis. One of the most acknowledged and approved chemotherapeutic agents is Doxorubicin (DOX) which is a non- selective class I anthracycline. In spite of DOX being one of the most acknowledged chemotherapeutic agents, its use has been limited by its toxic side effects and the development of chemoresistance. Nowadays, Thioridazine (TZ) which is a newly repurposed drug that was originally used in the treatment of psychosis, schizophrenia and anxiety, has been tested in the treatment of breast, ovarian, gastric cancers and leukemias. Methods: MTT was employed to assess the effect of TZ and DOX on the separately and in combination, with different doses and durations on the HEp2 cell line. The efficacy of both drugs was evaluated separately and in combination with different doses and durations on inhibition of cell migration on the HEp2 cell line. Results: The results of this study revealed that the highest viability was with the control group followed by the TZ group I (low dose), compared to the other groups. While it showed that the lowest mean viability was with the combination group VI (high dose) compared to other groups.
