Methods This review was conducted using PubMed and Scopus databases. It focuses on the following clinical and laboratory steps: the impression, the registration of the centric relation, the try-in and the finalization. Results According to the reported data in literature, impression, try-in and finalization are feasible with a complete digital approach. Registration of the centric is possible only combining the digital with the traditional one. Digital impression is accurate, but shows some limitations in the peripheral areas. The printing process, because of accuracy and its cost, can be used for the try-in of the prototype. Milling machine  is more accurate than  3D printing and offers a good level of retention and of satisfaction for the patient. Conclusions In relation to optical scanning, there are still some limitations because of the impossibility to perform selective pressure in the areas of the peripheral seal. Fully digital methods to register the centric are not described. More evidence based evidence on qualitative and quantitative results is required to validate digital denture protocols.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80190093","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}

Angulated implants used for implant placement which utilizes bicortical engagement of implants at the nasal cortex and pterygoid region in a flapless manner. The aim of this study was to evaluate the clinical outcome when 6 tall angulated implants were placed in a maxilla and restored with screw-retained fixed prosthesis after 3 years follow up.  Methods Total of 40 patients were considered for implant placement in the maxilla, 20 patients who underwent implant placement followed by delayed loading and 20 patients who underwent the same surgical procedure followed by immediate loading. Angulated implants were supported by Finite element analysis (FEA) comparing stress distribution on cortical, cancellous and basal bone on mesial and distal side of each implant with All-on-6 concept for maxillary arch.   Results Angulated implant shows 100% survival rate in implants and prosthesis, in both delayed and immediate loading protocols of maxillary rehabilitation. The FEA based on von Misses stress, shows little higher values for All-on-6 for cortical, cancellous and basal bone when compared with Angulated 6 implants design.   Conclusions Angulated implants a novel concept shows a good survival rate. Due to the bicortical engagement of implant the chances of marginal bone resorption around the implant, implant and prosthesis failure is minimal.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72693441","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}

One fiber post was luted into the root canal strictly following manufacturer’s instructions. Each sample was cut in slices in order to perform the push-out bond strength test with a testing machine. To express the bond strength in MegaPascals (MPa), the breaking load recorded in Newton (N) was divided by the area of the bonded interface (A) in mm2. The area of the bond interface was calculated as the area of the surface of a truncated cone using the formula: A = π (R + r) [h2 + (Rr) 2] 1/2, where R represents the major radius of the coronal post, r represents the minor radius of the apical post and h is the thickness of the slice in millimeters. The diameters and thickness of the slice were measured individually using a digital caliper with 0.01 mm precision. After the test, each slide was observed to detect the type of failure and classified as adhesive between cement and dentin (AD); adhesive between the cement and the post (AP); fracture of the sample, cohesive inside the post and dentin (FR); cohesive in cement (CC); mixed (M). \u0000Results  Group 2 recorded the highest values of adhesion strength,  group 1 the lowest. There were no statistically significant differences among groups 1 and 2 and controls. The most common failure mode was the mixed one and the less frequent was the adhesive type between the post and the cement. \u0000Conclusions  Within the limitations of this study, it can be concluded that the bond strength of experimental resin cements is comparable to that of a cement marketed by the same manufacturer, used here as a control and well known in the market.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2019-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81155195","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}

It may involve the paranasal sinuses (upper odontogenic infections, UOs) and cervical-fascial spaces.

A clear etiological and chronological relationship between the odontogenic focus and sinonasal infection was required for inclusion in the study. \u0000Results The causes of UOs were mainly dental implantation (29.8%) and tooth extraction (18.9%). In all cases, UOs were treated with transnasal endoscopic surgery, associated with transoral procedures in 24 out of 37 patients (64.9%). Empirical antibiotic therapy was used in all cases, whereas antibiogram-driven therapy was adopted secondarily in 22 out of 37 cases (59.4%).
